SteveCZ28 Posted November 27, 2011 Report Share Posted November 27, 2011 well its been a very long process since i blew my banshee up 4th of july thanks to a bad crank seal, causing the bike to diesel then lose compression. so ive been gathering parts for it since then, and have been slowly building my motor. has a new hot rods crank, new seal kit throughout motor, bored top end with new wiseco pistons. i was very weary of building this motor and i was really stressed about the possibility of another air leak in the new motor then destroying the money i put into it.and i wasnt sold on the yama seal stuff (the thin gray runny waterlike gasket maker) so i built a leak down tester for it. put in 6 psi of air, and watched my gauge like a hawk....it easily surpassed what would be acceptable leak down. as i only lost .5 psi over a 30 minute period so i went ahead and buttoned the motor up and installed it in the bike, then did my compression test today (as its hard to do a compression test on a motor flopping all over the ground when trying to kick it over. 4 kicks it peaked at 150psi on both cylinders. another pat on the back for me as i was just stressed about that. hooked up wiring, and nice to see spark again, although it had spark when it blew,which i was surprised to see it had spark after all the mud i scraped and cleaned off the flywheel. its spick and span now. but its always nice seeing it again after a re-install of all components. i do need a idle kit for my carbs as they are the tors version and dont have idle screws and i should be able to hear this beast scream again, and do some heat cycles on it....but sorry to ramble on, im just excited about my findings on the motor, so maybe ill have more than 15 minutes of ride time on this thing again haha Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted November 27, 2011 Report Share Posted November 27, 2011 Good to see another person has been helped out by this site.... and good job on tearing your motor apart (and from what it sounds) re-assembling it and doing a good job and taking your time. alot of people out there just slap them together and melt them down again and scratch their head....then point the finger at the machine shop.
