Re: why does the engine stall when accelerating?
1. Remove the airfilter box and try to rev. it up but dont yank it up rev it up in a 3sec time interval from 0-9000rpm. If it revs up replace your airfilter it might look ok but the material it is made of ages and with damp in the air closes up the micro holes in it and chokes the engine as soon as you rev it up. If you have an airbox don't fit those smaller individiual airfilters you would have to get it jet dynoed, what I am saying is fit the same type air filter back on or you will have fuel air problems. 2. Remove the exhaust manifold from the head, start it up and rev it up in a time interval of 3sec from 0-9000rpm. If it revs up your exhaust is blocked and you either have a wasp stuck in your exhaust outlet or it is aged and blocked. Try closing your mouth and nose with your hands and breath in or out, this is the same with your engine.
3. If this does not rectify your problem you will have to look at your carburator float levels or your coil packs. Let me know if it work or don't so that we could fault find your problem this is the easiest and the firts steps to follow.

Not sure on this one could be a restrictor in the carb top or a restrictor ring within the exhaust system which needs removing.My Yamaha ttr125 was the latter, it simply needed the silencer removing from the header pipe and the first 6mm of pipe cutting off.
The setting of the ignition is too ADVANCED and so there is PREIGNITION. Perhaps this is done to have the engine respond well into higer RPM and so if there was backfiring only when the start was missed , I would suggest that you try out to start and if not you must get the bike tuned once again for fuel settings and ignition setttings including timing.
hi, quite often i find people come to me with this problem, and the most obvious reason is that they clamp the pipe to high up, if your exhaust came with a supplied clamp, and the silencer has been manufactured with slots cut out where it fits onto original headers, place the clamp on the silencer but dont completely cover the slots, covering them will not alow you to tighten the silencer, remember you cant tighten up on a solid peice of pipe, you will have to leave about 3 or 4mm of the slot visible on the uper side of the clamp, the slot will soon seal up after rideing for a couple of weeks. hope this helps
It could be the exhaust baffles which are in the exhaust pipe tht have given away, you can remove the exhaust pipe assy and get it cut underneath and get the baffles electric welded..or rather spot welded and weld the exhaust back but the chrome will burn off and rust may thn take over ..or unless you paint tht area black( heat ressistant paint.),or better off is to replace the complete exhaust pipe assy.
Hope this helps!
Please check your exhaust pipe or the silencer. It must have been chocked with carbon and you have to remove the carbon deposit to run your motorcycle. Also clean your fuel tank as it could have dust deposits at the bottom chocking the fuel flow once it is in running condition. Please change the spark plug as recommended after covering a distance specified.
