hello i have a 96 bearcat i have just replaced the voltage regulator and main wire harness , it starts nice runs good untill i hit a high rpm , voltage regulator gets hot and wires running to it are warm. i cleaned carb and checked voltage at battery - voltage is in speck . new spark plug and plug cap. i also took the air filter off and it seemed to of helped a little. any ideas would be greatly appreciated tacklebox

 

I am wondering if your machine is running rich. If it is running rich the excess fuel will burn inthe exhaust and cause it to be very hot and sometimes glow a nice cherry red color.

Restricted air flow OR your valves being out of adjustment can cause this. This extra heat may be what is causing your trouble. These are also both easy to check.

That would be where I would start.

ok thank you sj i ran it in the garage for a couple minutes and notice a strong fuel smell comming out of the muffler. i checked the diaphram and it has 2 pin holes in it so i am waiting for a new 1 to come in appreciate the help tackle box

 

you order it already? put some rtv on the old one, and try, as back firing is fromt way too rich, usually... and thats probably not going to fix it..

check your float, turn your fuel/air to 2.25 turns out, and try again

 

ok well i will hang on to the old 1 i guess , when i took the old 1 off it seemed somewhat flimsy.... ,im not shure how firm it is suppose to be but my engine has very good vacume { when i put my hand over the air filter hole it darn near sucked it in, also noticed the spring had been cut and it had a flat wear spot on the outside of couple 3-4 rings . i am getting tired of taking the carb off so ... the screws are getting warn out ... i really appreciate the help on this site . i will rtv the old one befor i put it in the kitty parts box to help me remember the tip, bye the way she has 9600 + miles on her thankx again alot todd

 

Tacklebox, the kitty is just hitting her prime mileage wise! I am at just over 15,000mi on my 400.

Also was it backfiring while you were riding at a high speed or was it backfiring when you hit and then let off the throttle quickly while idling in neutral?

hello sj i turned the jet out 2/12 turns and it is better (didn't fix hole in diaphram....too cold out today and it snowing so i will leave it for now so i can plow later) not as much gas smell comming out of muffler .... speeking of muffler mine is in kinda rough shape when i started it today i noticed exauast comming out before muffler so it appears it has a leek , might this hamper the perfance cause it seems like there is still not as much high end speed . it is better i guess it's fine tuning now todd
