just rebuilt top end now exhaust is blowing

[adz_244]

hi am i right in thinking on my expansion chamber its just the 2 o rings and then you push it into the cylinder ? ive just rebuilt my top end put new orings on the exhaust and its blowing pretty bad from the cylinder any ideas?? should anything go into the exhaust port before the pipe or no

looks like there should be a washer that goes in the cylinder before the expansion chamber can anyone confirm this

ya isnt there a copper or steel washer/ring ?? i always put a little grease on it to keep it from falling out when i put my pipe on sometimes they get stuck up in there or sometimes they fall out to easily ... i would imagine there is one that should be there??

thanks i found a microfische online and yes there should be one, dunno where the hell it went or even if it was there in the first place.

No, it should only weigh a few grams. ?

I doubt the missing washer is causing your leak. I would take a closer look at the o rings as they are what really seals the pipe. Sounds like they aren't tight enough going into the cylinder.

I'm assuming you replaced the springs, they'll weaken over time and can allow some movement

im going to take a closer look at the orings cause im sure that washer was not there i'll also replace the springs thanks for the tips

found the problem.. where the springs hook on to the bracket on the pipe i found a split in the pipe on the underside of the bracket
