and ive had to spend WAY too much money on this thing now. basically spent what amounts to another kit, gaskets, cylinder head, etc

 

really hoping I don't have this issue with my new kit cause ima be pissed!

 

Might be a good idea to keep the 249cc OEM cylinder and piston next time like I decided. $175 core is way less than it would cost me to buy new parts and if my 351 craps out I am just a couple of gaskets and MCM away from they way the bike used to run, and reliable.

 

Curious to see what might be causing this issue. Sorry to hear of the problems encountered by buyers. I feel fortunate the 350 kit I received is still running great with no issues. Thank you bill

 

Could be worth looking at the kit number to see if there might be a grouping related to materials used at that time.

 

I just ordered a 351 kit and it should be here this week, should I hold off on installing it? :S

 

I'd end gap the rings off the piston just to make sure that's been taken care of. Reinstall them as described in the service manual.
As a precaution I'd go over the top & bottom of the cylinder gasket mating surfaces with a scouring pad n contact cleaner before assembly to be 100% positive they will seat properly.
I would ask for suggestions from bill before assembly.
Best of luck and enjoy !

 

^ agree.

 

i put about 70 miles on my (2nd) rebuild this weekend. taking short trips to break it in, "prove" it, and hopefully learn to trust it again for longer rides.

 

Okay thanks, I'll make sure to gap the rings and I downloaded a PDF of the service manual. The kit is still stuck in customs, I'll report back when I get it.
