Because somehow fuel gets in the exhaust and backfires, the best way to fix this problem is to clean out your carb, clean the pilot and jets inside of it, most people that done this said that it was the problem.
backfiring is a sympton of a lean condition. look for vacuum leaks and fuel delivery problems.
MY HONDA EX400 2000 ATV IS BUSTING OUT BAD. CLEANED GAS LINES AND CHANGED PLUGS. RUNING TO HIGH RPM, BUSTING OUT SO BAD. IT HAD BEN SETTING FOR SOME TIME. THANKS, STEVE racingfordruns@yahoo.com
I do not know of any snowmobiles that have a button like that. They all have a kill switch that shuts the engine down, and if you push it while under higher rpm's and release it, than there is a chance for backfire.
removed cats, backing down from high rpm rev ranges, hot engines, high amounts of fuel going into the engine, and the excess gets burnt after the combustion process in the muffler. a good cold air intake will help with backfiring, and a wide full exhaust system.
rev limiter will only let the RPM's get so high then it cuts back
Unburned fuel is igniting in the exhaust, you may have a fuel metering problem, or a timing problem. If the timing chain is stretched it could throw off the spark timing at high rpm.
The rpm required for an alternator will depend on the result that you want. At the very least, you will want 1200 rpm. The rpm's can go as high as 5000.
a 4 0hp 4000 rpm 3 stroke engine with 2 fly wheels and standard transmission.
The torque spec on a 1989 Yamaha 350cc ATV is 75 foot pounds at 2000 rpm. Torque is used to get the vehicle moving at low speeds until the horsepower takes over at higher speeds.
Say when you pull up to stop light or sign and take off, engine boggs dwon until RPM's rev?
when u first start the car it will idle high, around 1.5 rpm to 2 rpm. when its warm up it should idle between 700-1000 rpm
it only studders at low rpm it runs great at high rpm or accelerating only at idle and take off rpm
