Hi Ox noob on here

Question & request - buddy has a 1995 Big Bear 350 2 x 4 chassis num # 4UH 017286 1995 # I have the YFM 4 x 4 manual & wondered if they did one for the 2 wheel drive as it runs like a cripple dog, tried carb settings for 4 x 4 but no joy.

TIA

all i have is the 4x4 on page 1 of this thread, post #3. i know the carbs are a real pain to get right, i had to do mine about 8 or 9 times before it was right. not sure if the specs would differ that much ...

Appreciate your reply, that was my thoughts also but may need to try messing with needle height & Pilot jat a bit more, unfortunately I am not the firsy person to look at the machine so will have to strip carb myself & check all gaskets & diaphram etc yhen take it from there, forgot to mention this is a Euro model also so could be different specs due to temps & altitude here etc.

One other point would the carb being out of adjustment cause occassional backfiring when trying to rev engine or is it possibly Ignition related ?

Grateful for all comments though

Cheers....... Fishy

i think if the bike is back firing, there is too much air mixing with the gas. i could be wrong, but i thought that is the problem. check the rubber manifold from the carb going to the block for leaks and cracks. you can spray some quick start while the bike is running at that location and if the bike changes rpm, that's the problem ... anyone else on here have an opinion? please share ...

OK, thank you anyway. I already tracked it down to a dirty headlight switch and cleaned the contacts. I have seen this type of plastic before, avoid contact cleaner spray! No idea what the next thing will be, got to ride it a while and see.
