I suggest you get a haynes manual and read it, then you'll know what's involed. It's not an engine out job, just top end, new gaskets required (£20for top end). pistons will be he hardest to source I think +.75mm is the only ones you can get now and a specialist to rebore and hone the engine (who will need the pistons for measurement) I woudn't recommend running the bike like that as you'll blow seals in the crankcase, Get a second opinion off someone who can actually see the bike in person, because I can only go off what you tell me on here.

Wow i guess i would probably have to get someone to help me on this.man i was really exited with this caferacer project when i saw the show on discovery channel the worst thing is that i already invested over $1,000 o well it is what it is. i check compression today again and the left side stay on 0 the right goes up to 70 so i will do both sides. thanks for your help Drewpy.
