Specialists like Race Tech also offer upgraded cartridge kits for the early VFRs, usually referred to as "emulator" valves, along with springs, fork parts…even in-house rebuilding services. So, if you feel that your suspension could use some modernizing, there are options. In our case a careful reassembly with 10-weight fork oil is as far as we'll go with this project.
Next on the Project 37 list is the front suspension and steering bearing replacement. I begin with fork disassembly and inspection. These forks were found to be in excellent internal condition, which would be expected at only 16K miles, needing only oil seal replacement. Here we see the assemblies freshly disassembled and before cleaning. (Right) Beginning with the third-generation VF/VFRs our forks advanced to "cartridge-type" fluid damping. What changed is the addition of the flow restricting cartridge (circled). The advantage of a cartridge is that it can be tuned to restrict fluid (fork oil) flow to a lesser or greater degree, allowing fine tuning of damping rates. This is accomplished mainly by the number of wafers stacked internally in the cartridge (a simplified explanation). Instead of being limited to altering the size and number of restrictive holes (arrow) in the damping tube as done with the earlier forks, the addition of the cartridge gave the VFR a step up in suspension sophistication.

Here in the northlands, we're enjoying a "cold snap," as it's euphemistically phrased in these parts, so I spent a day at the indoor workspace, tackling the various hydraulic actuators on Project 37. These include the two brake master cylinders, clutch master and clutch slave along with their associated assemblies. The neglected clutch fluid on this bike meant extra cleaning of those components plus a new sight glass, but everything went together well. I always break these assemblies down to their individual pieces, clean, inspect, polish, etc., and reassemble with fresh rebuild kits from K&L. The right-side foot brake assembly in particular is a lot of detail, but you're rewarded with a smooth operating, good-looking part.
Next, fork assembly and mounting. With Project 37's body panels away for painting, I'm tackling the brake systems. This bike will require a full rebuild, including all three calipers, brake master cylinders plus the clutch hydraulic components. Jeff, the owner, has chosen to go with complete caliper rebuild kits from Brakecrafters. These were sourced directly from the company via their eBay store and cost about $60 per caliper. The kits are very complete: Seals, pistons, bleed valve, rubber bush/seal, crush washers and even Red Rubber Grease. The listing states that these parts are made in Japan and Europe and they look, feel and fit like high quality components should. This is a convenient and cost-effective alternative to hunting down individual components on the web. I had heard of this magical Red Rubber Grease but had never tried it, but I'm a believer now. This stuff is made from castor oil and is specifically formulated for rubber brake parts, NOT for metal-to-metal lubrication. It lubricates while adding corrosion and oxidation protection. A very light coating is all that's required and the parts just glide together, compared to using brake fluid during assembly. The tiny containers provided in our three kits will probably last me five years. It's always nice to find another useful tool. Next up I'll rebuild the three master cylinders and the clutch slave. Keepin' 'er movin'. What: 1985 VF1000R Interceptor Where: Elkhart Lake, WI Why: A striking example of an iconic model Price: Bidding at $4050 UPDATE: Sold for $11,000, then relisted for $12,500 BIN or make offer. The VF1000R needs little introduction. Built and styled for European endurance racing, the "R" was offered in the U.S. market for 1985-86 and is a Honda collector's staple. This example shows 27,569 miles and is offered from Throttlestop's collection. The photos show an original condition bike with a near-perfect paint presentation — I suspect it must have had a quality repaint at some point. They state that the mufflers are original, but they look like period slip-ons to me, possibly Cobra brand. The eBay listing has lots of hi-res photos and the bike claims to have been recently serviced. There's also a short running video included in the listing. It looks like a nice one. The listing ends Monday, Feb. 7. Throttlestop is a collector vehicle seller, repair/restoration and museum facility, located adjacent to the beautiful and storied Road America race course in the rolling hills of the Kettle Moraine State Forest in Elkhart Lake, Wisconsin. The museum is open to the public (fee applies) and Throttlestop hosts a cars & coffee type event during the summer months. After many hours of cleaning, repairing and sanding, the 18 individual pieces from Project 37 are finally ready to be delivered to the painter. Fortunately, the wheels cleaned nicely, again with hours of detailed labor, but being able to mount the bike's original wheels is a good thing. I have a reproduction decal set on hand, which I will apply to the fresh color and then back to the painter for clear coat. We have settled on a Chrysler pearl paint code, which we will tweak for the best match to the original Pearl Crystal White. Steve at Steve Nick Customs, Woodstock, IL, is the paint artist for this project.
The 2022 Mecum Las Vegas auctions concluded this past weekend. I had hoped to be there with my 1112-mile 1986 VFR700 but a smart buyer grabbed it from me last Fall, so I was left as an internet spectator. Here's the results listed for the various V4 models crossing the block this year. 1986 VFR750F Sold: $7700 This RC24 shows 21,371 miles and presents well. Mecum's typically uninformative description states simply, "running condition." The bike appears to be in mostly original condition with damage-free cosmetics, period correct Kerker slip-ons and Fox shock. The passenger seat cowl is present but the windscreen molding is missing. An above average example with a bit less than average miles. The selling price indicates a general rise in second-gen values — and it's about time. 1984 VF1000 F2 Sold: $2420 The auction listing is a little confusing on this Euro-spec VF1000. It's listed as an '84 but the description states that the fully-faired F2 was introduced after the '85 model year. In any case, this is a unique take on the big-block VF in the U.S. and sports the extra fairings, a second radiator and twin headlights. This example looks to be in average condition with 41,842 miles and an aftermarket seat. 2001 Magna 750 (VF750C) Sold: $2200 This V4 power cruiser stayed in Honda's lineup until 2003 and featured an internally-modified 750cc V4 tuned for mid-range power with 5-speed transmission. This example shows beautifully with only 8043 miles on the odometer. It's selling price seems to indicate the general lack of interest in the mid-displacement cruiser market. 1985 VF500F Sold: $3300 This mini-'ceptor is represented as an original survivor and certainly shows the appropriate patina, all Armor-All-ed up for the auction. Showing 10,530 miles, I would call this bike an average example, and the seller should be very pleased with the sale price. 1992 VFR400 (NC30) Sold: $13,750 Here's a beautiful example of the final-year VFR400, cleverly coded by Honda as the NC30 to channel it's famous sibling, the RC30. This model was never offered in the U.S. market but have become a desirable (and now legal) import for collectors and lovers of small displacement point & shoot sport bikes. This one shows 11,657 miles and proudly displays its classic 90's livery. Very nice. 1988 VF1000 FE Sold: $5170 This Euro-spec VF1000 is designated "FE" and is a lovely survivor despite its 64,468 kilometers. There's some expected patina including some left-side muffler rash and the mirrors are not original to the model. This is a very unique bike here in the U.S., and a pretty cool alternative to the over-priced and less-friendly "R" model. 1982 V45 Sabre (VF750S) Sold: $1980 This may be the buy of the weekend — a first-year V4 Sabre in very original condition. No word on the miles (or anything else) but this appears to be a well-preserved example. Aluminum corrosion is an issue with the early VFs, but this one doesn't look too bad, and the irreplaceable mufflers are intact. A lot of motorbike for under $2000. 1987 VFR400 (NC24) Sold: $7700 The NC24 is the second generation of the VFR400 series ('87-88) and introduced the 8-spoke rear wheel and single-sided Pro-Arm swingarm to the model. No mileage listed, but this example is exquisite in one of the three color schemes available this model year. Well bought and well sold. 1982 V45 Magna (VF750C) Sold: $2750 Another first-year example of the V4 lineup, the Magna was Honda's response to the Japanese cruiser trend of the 80's. This example is mostly original, is all shined up and shows 18,580 miles with muffler rash on both sides. These are not sought-after models and I think the seller should be pleased. 1985 VF1000R Sold: $12,100 The "R" model VF1000 was sold in the U.S. in 1985-86 but introduced in Europe in '84. A complete redesign of the "F" model, the "R" brought gear-drive cams and many performance upgrades. It was also 85 pounds heavier and was less comfortable, a nod toward its intention as a homologation bike for endurance racing, which never materialized. Still, the "R" remains a desirable classic, and there's no denying the punch delivered by the big-block V4. This bike indicates 27,900 miles and is said to be "highly original." If that's in fact the case, it's an exceptional example and the selling price reflects it. 1984 VF1000F Sold: $7700 Wow, what a beautiful example of the single-year VF1000F. Belying its 38,892 miles, this example sparkles in its classic red/white/blue livery. Looking over the photos, I have to believe this one has had a cosmetic restoration. The listing also states that the engine was rebuilt in 2017. The selling price is the highest I've ever seen for the model, and hopefully, it signals an uptick in value for the traditionally underrated "F" bikes. 1984 V65 Sabre (VF1100S) Sold: $1870 Another great buy, this big-block V65 is represented as original and unrestored. These bikes were stoplight brutes, could smoke just about any comers and were direct competitors to Yamaha's V-Max. Available only in 1984 and '85 with its trendy square headlight and long fork styled for a chopper-esque look. This one shows 32,023 miles and is going to bring back some memories for very little money. As I progress through the refurbishment of Project 37, a 1993 VFR750, one of the items at the top of the checklist is a valve clearance check and adjustment. Beginning in 1990, the VFR's valve adjustment is accomplished via the "shim-under-bucket" arrangement whereby replaceable shims of varying thickness are exchanged to achieve the recommended clearance, also referred to as "lash." This design provides a very positive mechanical setting which is able to survive high-RPM operations without the threat of "spitting" out a shim as can happen with a "shim-over-bucket" arrangement. Honda must have thought that our high-performance, high-revving engines deserved this design, though interestingly, the earlier generation VF/VFRs seemed to have gotten by with the simpler screw & locknut approach. In fairness, those earlier systems required old-fashioned rocker arms for valve actuation which are more complex and heavier, adding reciprocating mass and, likely, high RPM flexing. But, that earlier design makes our life easier when adjustment time comes about. In any case, owners of 1990+ machines will need to set aside more garage time (or expect to pay a shop more) in the event their valves are in need of clearance adjustments, which likely leads to this task being put off or outright ignored as part of a normal maintenance regimen. Of course, that's understandable when an owner realizes that, in order to replace a shim, the appropriate camshaft needs to be removed from the cylinder head…and there's four of 'em. So, if you're confident in your wrench-turning abilities, here's a video showing the steps involved in accessing the area for the clearance checks and removing/installing the cams, if necessary. In this case, all eight valves of the rear cylinders required adjustment along with three of the front intakes and none of the front exhaust. So, three of the four cams required removal. The second video shows the math exercise required to select the correct replacement shims. I wish I knew how to make math interesting but, alas, I don't. NOTE: Once I gained access to the valve covers this entire operation took me about 2.5 hours of labor plus the better part of a week waiting for my local dealer to provide the three shims I didn't have on hand. There should be no additional parts needed beyond the required shims, though this is a perfect opportunity to replace the spark plugs. As noted in the shims video, the Haynes service manual is the more thorough guide for this operation. Carbs From December, 2015 The old carburetor vs. fuel injection debate is long dead. "Fuelies" may have had a rocky start with the old mechanical automotive systems, but the EPA writing was on the wall and technology won out — for the better. The first mass-produced motorcycle injection system appeared on the 1980 Kawasaki Z1000 Classic, and our VFRs joined the game in '98 with the VFR800FI. But those of us who play with old bikes still fumble about with carbs. I should create a T-shirt which states, "Still Plays With Carburetors." It's often interesting to disassemble a set from the latest project bike to see what mischief has been wrought by previous fiddlers. Even nostalgic types have to admit that the new-generation performance tuning via digital mapping is more precise, effective and much, much easier than old-school trial & error with needles and jets. It's also a natural approach for this digital generation. But we're stuck with our carburetors and I will say that there's a certain satisfaction in getting all the parts and ports to align and end up with a sweet-running carbureted V4. Or maybe I'm just old. What: 2000 VFR800 FI Where: Southwest Florida Why: Exceptionally well-kept 5th-Gen Price: Asking $5000 1998-2001 VFR fans will tell you in no uncertain terms that theirs is the best generation of Interceptor out there. And owners of the one-year Pearl Shining Yellow bikes may be the most vocal. They all have a point, of course. Sitting in the sweet spot between the gear-drive cam design of the previous generations and the new age chain-drive VTEC models, the fuel injected 782cc V4 got a few tweaks for the 2000 model year. These included an updated EFI system, oxygen sensors and the "fast idle" lever deleted, while all 5th-gen bikes got Honda's new CBS linked braking system. This two-owner example presents beautifully despite showing nearly 29,000 miles. Obviously well cared for with full maintenance records and a few nice extras: Bar risers, alarm system, aftermarket windscreen and color-matched Corbin seat. The $5000 asking is at the high end, but I'm thinking you get what you pay for here. If yellow is your color, you'd be hard pressed to find a nicer example. While in the process of dismantling the various systems on Project 37, a 1993 VFR750, I came upon this science experiment inside the clutch master cylinder. This is exactly why there's a universal recommendation to flush brake fluid every two or three years. Yes, this will clean up with a water scrubbing but the situation is the same downstream in the lines and clutch slave cylinder. In fact, when I attempted to drain the fluid via the slave's bleeder valve it wouldn't even pass this crud. Flushing/bleeding your hydraulics isn't difficult, costly or time-consuming, but, if allowed to reach this point, it's just the opposite. This will require a complete system disassembly, cleaning, new master and slave seals and ideally a hydraulic line replacement, which we're planning in any case. If you presented this to a shop you're facing hundreds of dollars in parts and labor. Flushing your own systems costs a $4 container of brake fluid and 30 minutes of garage therapy. Flush your fluids! |
