Just got a rgv250L (seems to have 89,90,parts with 91 fairings), picked it up cheap because of the high ks (51k) and rebuilding it.
So far i have:
Cleaned the hell out of it!
then,
Started with the brake lines, bleed them and still spongy as hell, so binned them for braided lines. new rear pads, had to split the caliper to get them in... doesnt look good, hopefully pistons wont leak! also on brakes, should i use dot 4 or 5 fluid?
Ordered new Power valve actuator cables, bottom valve was jamed open. no wonder it had nothin under 8000rpm.
Pulled the powervalves and after getting them out with an impact driver, replacing philips screws with internal hex, who thought philips heads in a hot end was a good idea? anyway PV look good, after carbon removal, no cracking or fracturing, a little scoring on rear cylinder pv faces. Apparently the pin can fail and blow the engine?
Nil marks on the rear piston i can see through the exhaust and PV ports a little wear on front piston from exhaust port divider.
Attempted to remove carbon from expansion chamber and exhaust... no luck yet... will try and get hold of an oxy acetylene torch, that should fix it!
Thinking about doing a top end rebuild.... cost and where do i get a kit?
And exhaust, expansion chambers for more power. any susgestions?
Any help/advice will be appreciated.
