gstallons Posted July 11 Share Posted July 11 Now , I do not know what the allowed % of leakdown is on this cylinder is . MOST tests allow 5% or less as being perfect . I would test at BDC, halfway and TDC to know how it is doing throughout the cycle. It doesn't take that much more time to do . Use a ratchet/socket on the c/shaft for no surprises ! Watch some YouTube videos to make sure you are happy w/your procedure. 1 Link to comment Share on other sites More sharing options...
Chuck Posted July 11 Share Posted July 11 (edited) On airplanes, the cylinder needing checked is put at TDC compression stroke. The prop is dangerous and is held tightly before turning on the air. The regulator sets the first gauge at 80 psi, and the second gauge shows the leakage. The prop then can be turned back and forth a degree or so to get the highest reading. A normal cylinder will be 75 psi or above. I don't get terribly concerned until it reads 70 or under. This will show leakage from rings at the crankcase breather, intake valves at the carb, or exhaust valves at the (wait for it) exhaust stack. It won't tell anything about valve guides, but since it is at TDC you can feel how much clearance there is by wiggling them around. Edit: I would put an on/off valve on the hose to the cylinder on the pictured rig. It makes things simpler. Edited July 11 by Chuck 4 2 Link to comment Share on other sites More sharing options...

Relay #2 is working because the headlamp is ( I assume) working ? The way to verify it is working (since you don't wont to lean over the bike) is to push the horn button. Relay #3 is working because the starter is allowed to crank. Relay #4 is working because it supplies +to Relay #5 Relay #5 would give you evidence of working when the fuel pump would (make noise) function . The #5 relay controls the + to the fuel injectors , ign. coils and the fuel pump. I oughta print this diagnostic rundown and carry it on the bike and leave a copy in the shop manual. 2 Link to comment Share on other sites More sharing options...

guzziart Posted July 13 Share Posted July 13 Yeah, I marked up my relays, fuses, etc. after seeing yours Doc but mine aren't as elegant. 3 Link to comment Share on other sites More sharing options...
