A Tear-down Begins

3/24/2016

Number 18 is a 1986 VFR750 R/W/B with 10K miles showing. Yesterday I began stripping the bike to prepare for its first start-up in at least seven years. This always begins with removing the bodywork followed by getting the carburetors on the bench. With the fuel tank off I was greeted by this "high performance" modification.

Peering through the many hi-speed holes I glimpsed some fuzzies, which past experience has told me would be a mouse house.  Sure enough. Amazingly, no other evidence of the little critters could be found. 

The carbs appeared clean and shiny. I once had project where the mouse pee had worked its way downward through the air filter and soaked the carbs, freezing the butterflies in place.

These look great. Problem is, the throttle shafts are locked in place, with no obvious clue why. That will require some further investigation.

The old fuel, which long ago turned to a puddle of varnish in the fuel tank, must have been drained or evaporated away before solidifying in the carb bowls. They too look very clean.

With the carbs removed I found only a nice protective layer of shop dust in the cylinder valley, with the factory markings clearly displayed in pale blue. I've found these on all my VFRs and assume they were some sort of engine assembly notations.

With some fogging oil sprayed into the cylinders, the engine turned over normally by hand. Next up I'll adjust the valve clearances, do a compression check, remount a fresh set of carbs and see if she wants to run.

Update: Next day the engine fired right up and warmed up normally with a jetted set of carbs installed. The Kerker sounds great. All the valve clearances were .001" tight, and the compression readings were nicely consistent. Now I'll remove the carbs and begin detailing the rest of the bike.
