Hey guys new on these forums new to blasters not new to working on quads,bikes,etc
Anyway customer sent me a blaster engine to work on. Said it ran poorly couldn't describe anything to me by what he meant. Anyway first thing came to mind would be wore top end..what you know took it off and I could physically move the top end around in the jug. So we decided to replace with new cylinder piston rings gaskets all back to stock.reeds looked intact so I left them alone..Anyway brings bike over I install motor mixed some 32-1 fuel with some spectro and it started and sounded great..off he went yay!....two days later he said he was riding it lost all power won't idle and has no power...still riding with the gas I mixed for him as it was a full tank and he claimed was his first ride...brings it back only will start with playing with the gas..doesn't idle. And will not rev and will only go maybe 2mph and smokes bad. Pulled plug and it's a oily mess. So now I'm thinking leaking crank seals. I go replace both and the clutch side is bad. Put all back together new plug..and start it its the same thing..not so much the smoking now but no idle no power checked the comp it's 60psi full throttle about 20kicks. Put it on another bike in shop to check Guage and it was right on the money..also when I pulled the plug it was wierd it has no color to it I mean it looks like I just put it in there with no run time. When i had it running for like 5 min trying to adjust the carb to see if it was off. Haven't took the jug off yet to check top end. So my question being with the bad crank seal could that roach the top end that fast? I'm not a 2 stroke guy so this is alil foreign to me..I didn't leak down test either due to a so called friend borrowing my tool and not returning it..any help be appreciated. ..
