TheHarbage Started a new thread Blown Clutch Case Gasket

11/20/2018 11:39am
tc 250 2015, the bike conked out on me at the track and wouldn't kick over again. I noticed that oil was seeping out from the clutch case gasket by the power valve. Would this cause the bike to not kick over? On a side not the kick start sometimes doesn't fully retract back and gets about half way when...

Thanks for the tips guys! I’ll put them into practice and report back ! I’m always baffled the amount of riders who don’t warm up at all! I’ve seen pensioners warm up more before a game of bowls. Going to readjust my levers, breath more ect Being told to grip a 250 2 stroke less seems counterintuitive when it’s trying...

after not racing for over 5 odd years thought it would be a wise idea to throw my leg over a hussy 250 and I'll be starting my first race back this sunday coming. Thing is I've been practicing a handful of times and even though i feel good my arm pump doesn't seem to shake off, any tips?

Yeah its a 2015, yeah it seemed to run fine on the 178 before i rebuilt. if i recall when i contacted the shop they said as its was a nickel lined cylinder it couldn't be bored out and so my only option was a sleeve. Never really considered a new cylinder....expensive much i guess?.

Yes Keating all back up and running now! Smile so had the mechanic run through it all turns out my top end rebuild was done correctly and so couldn't explain why there was score marks, you can't feel them with your finger tips so I'm going to run it in and ride a couple of hours and take it off...

Cheers will do! Update swell..... I ran a compression test and it only hit 130psi -_-, i have changed the base cylinder gasket as i thought i could see some coolant in the cylinder (could this have caused the score?). put it back together and the compression was the same, I'm guessing its the ring gap now. Question is now...

If it's not the ring gap, it might be too big of a piston for the cylinder plating.... You possibly got a slightly larger piston for slight worn cylinders!! Check and make sure your piston is the smaller size. I think Vertex pistons come in size I & II.... Look on the top of the piston and see. To be sure of proper clearance, check the measurements with a micrometer. Good luck!!!

Ive had a profession race mechanic go all over the bottom end and replace the main end bearings so thats fine. I did have an issue with the power valve first time installing it as it was getting stuck but i cleaned it up and it now has movement. Ive just checked the jetting and the only thing that was...

Also....When i sent it off for the replating they took the power valve apart so it came back in pieces, i reinstalled it but it would get stuck open. I managed to lube it up well so it stays down now, i can push it up with force as its under tension. Don't know whether that helps.
