hurtank Posted September 27, 2009 Share Posted September 27, 2009 i think my bike is misfiring. i did a little research and the symptoms are similerBasically. my problem is. i recently got my road bike back with a few engine adjustments. and since then. after running for about an hour. my bike. at low revs. starts to sputter untill its above 30 MPH. i dnno whats causing the problem. i will get a video of it but it sounds like the engine is dying. its all brand new parts in the engine exept my gearbox. and im worried becuase i just splashed out 340 quid on it.

hurtank Posted September 27, 2009 Author Share Posted September 27, 2009 lol i cant. shops not open till monday. i would rather not go back though. i checked my spark plug today becuase someone told me it could be that. and its not the original spark plug :S also i was told that alot of MX bikes often have pressure build up in the petrol tank where there quite highly revved so i opened the cap a little it made a small diffrence.

hurtank Posted September 28, 2009 Author Share Posted September 28, 2009 ok small update. i tried running with my choke fully on so it seems to be a fuel issue. luckily. i have a carb built for a 125CC engine ready to stick into my bike. i hope to god this works. i changed spark plug and put a new breather pipe on my petty tank to no avail. only other think i could think would be a valve making a popping noise also whilst im here. im thinking on putting a smaller sprocket on the back of my bike. if i get a pic could anyone reccomend me something?

hurtank Posted September 30, 2009 Author Share Posted September 30, 2009 the bike only had 2347 miles on the clock and smaller sprocket on the back. its acceleration is fine i just want to go faster. Quote Link to comment Share on other sites More sharing options...
ozz Posted September 30, 2009 Share Posted September 30, 2009 if you just put a small sprocket on the back without changing the front then it will just slow down you acceleration but give you slighty better top end.change the front sprocket along with the back to sort this out.
