seals

[dlporkchop]

Have a 88 blaster. Replaced top-end gaskets (base, head, intake, exhaust). Cleaned carb, adjusted float to spec. Changed oil & smoked like a mosquito truck. Replaced right &left main seals. Ran great for one day. Next morning went to river & ran good. Tried to start again and had no power to barely run. Compression before main seals 138 psi, after 136-138 psi. Is there another seal (countershaft?) where I can be losing compression while running. Positive of seal replacement (manufacture mark out). Any suggestions? Be back in an hour in an hour.
Thanks

leakdown test..you replaced seals, how were the main bearings?? try a fresh plug?? does the smoke smell funny? hows the tranny fluid level??

New iridium plug. Main bearings tight as far as me turning crank over. Oil was low, and when I changed it to 650mm? per spec, white smoke as in right main seal leaking trainy fluid into crank. Replaced, ran good that day and next morning? Still good compression when I try to kick start it. 2004 stator in, good spark and power out of cdi. Just seems like right main seal didn't hold?

that or the case halves are leaking.

Never broke case! But after changing oil & filling to capacity, white smoke when running,(indicates right main bearing seal. Replaced both left and right seals, ran great one day and one morning. Now won't start unless I pull-it. Then not enough power to put in gear. Does left counter shaft
bearing seal leak into crankcase if bad?

Did you grease the new seal when you put it in??

 

[dlporkchop]

Definitely! Just replaced wheel bearings and A-arm bushings on 2002 today. Cleanliness and grease all the way!
