It has 28189 miles and was stored indoors, is that bad mileage?Coyote wrote:First off, don't automatically assume the crank seals are bad. I bought a 77 GT750 that sat idle in a chicken coop for 25 years. The crank seals were fine.
For the wiring, there are 2 harnesses. Forward and rear. Paul Miller generally has both. They are pricy, but worth every penny. I bought mine from him. Supple, soft and correct.
For flushing the oil lines, buy a cheap pump type oil can. Remove the pump from the bike. Remove the six bolts that retain the banjo fittings from the block. Now fill your cheapo oil can with plain old rubbing alcohol. If necessary, grind the tip of the oil can so it fits in the tiny hole in the oil line manifold NO COMPRESSED AIR! It will destroy the check valves. Just pump alcohol through the lines from the manifold end several times. Now stick all six banjo fittings (one at a time) in your mouth and try to blow back through them.. No air should pass in that direction. If it does, the check valve is stuck open and needs further attention.
As a final test, dump the alcohol out of the can and fill it with 2 stroke injection oil. Pump all six lines full of the oil and hang the manifold on a nail. Place a clean rag on the floor beneath it. Wait 24 hours and check. All lines should still be full and none has leaked out onto the rag. If one or more has drained out, that check valve is still stuck open.
2 questions. How many miles on the clock? Was the bike stored indoors or out?
Turns over just fine.
Thank you for the details on the oil pump.
1. Your bike was not fitted with a fan from new,this was dispensed with by Suzuki fairly early into the production of the K model in most markets around the world,but you could at one stage buy the fan if you wanted one as a spare part.
Be very concerned,do not put the bike back together until you have this sorted with the piston!!
