Rebuild project backfires as soon as you let go of the throttle - and I don't mean pop, pop, pop I mean BANG! BANG! BANG!. Immediate thoughts?

There are many options for my RD07A, but which one is the most gooder? I have a leo vince on my 690, and I like it, but im not against other manufacturers. Please let me know which one I should get, which is best bang for buck? Highest performing? Lightest? whatever info you got I wanna hear...

thinking ahead to what could happen if my engine died! so,has anyone put the 650 into a 600 frame? what other parts would be needed,electrics and carbs i guess? dont really see any big probs with this just interested in hearing views. dont think my engine is going bang! just a daft idea i have...

Has the brake pedal on it. Mine's bent and a big hammer has failed to bang it straight. Don't need the footpeg. That's still fine.

Our PVR box is playing up and the cheapest way to get the latest whizz bang version is to take either Sky Sports 1 or 2 for one month and they will send us a new box. We can then cancel and keep the box with just the basic channels. Question is which is the better (or more diverse) channel. We...

Two times in the week i had this issue, but it was perticulary violent this morning. -When I start the engine after a night at -1/-5°, it takes 4-5seconds before a big BANG sound... I really do not know what it can be, and I am worried to damage the motor/exhaust. A weak battery is not...

Thought the title would get some attention, however the problem is somewhat dull annoying (for the neighbours anyway). My Alp has just started backfiring on start up. Not every time but often enough to worry me. It's due a service at 18,000 in 400 miles and although it shouldn't take long to...

Hi all, need a bit of help and advice on this one. Last week my exhaust started blowing, traced it to the joint from the real cylinder behind the shock. As a temporary fix I slapped on a little exhaust paste to seal the joint until I had time to sort it properly. Today I got the bike out of...

I crack my transalp650 to start it after a week of rest. It cranked for 1.5 seconds and then a loud bang sounded. I thought the engine blew to a million pieces. I could see some black smoke coming from the exhaust. I got scared attempted to start it after 2 minutes it started immediately and all...

My Vara's not liking the recent snap of cold weather. Noticeably down on power, requiring more revs to get to "normal speed", feeling like I'm dragging a weight behind me (other than myself of course) and popping and banging like a goodun on the over run. Oh and not keen on idling either unless...

I have a strange problem with the @ that i have lived with for a long time - and the time has come to do something about it....after having an "altercation" with an old lady.. :argue: I have a Dynajet fitted, with an after market Micron exhaust and a K&N filter. Sometimes(without any pattern)...

Ignition kill switch on the over run + group of chavs = :lol: Feck me it makes a loud backfire! Just hope it's not too bad for the bike. :oops: :twisted:

Hi!! Just since two days, the exhaust does an occasional 'bang'!! This happens when I release the throttle... not while accelerating. Is my exhaust on its way out?? Cheers, Tijn
