ok, so i took my 4 wheeler to an authorized honda repair shop because after installing an HMF sports slip on exhaust i kept bogging while trying to run in the winter time. I was also having the problem with the cold start as i see many others are. so the repair place installed a 170 main jet, and a 42 slow jet and adjust the carb, it's still a pain to get it to start in the cold (i live in northern Ohio) but when it does and gets warmed up it will actually run if i keep the choke on a lil over half way.. is that normal? i'm thinking it's probably not for the best to ride it like that but thats the only way it'll run, if i move it up anymore it'll bog out realllll bad..

any help would be greatly appreciated!

thanks,
tim

Welcome to the forums..

I think you may actually have to step up the main jet during the cold months, and drop back to the 170 in the summer...Are you running with the airbox lid on or off?

If you are running no airbox lid, put it back on for the cold months. Or rejet for the cold weather. Don't run with your choke on.

Agree also^^^^^^ plus running the choke on builds excessive carbon on the plug causing premature fouling, by running the choke your trying to richen up the carb by restricting airflow to get more fuel delivery, like red stated if your lid is off put it back on and that should help.

Choke is only meant to be used to richen up the mixture while starting. Try going up a size on the pilot jet.

Pilot controls idle to about 1/4 throttle needle controls 1/4 to 1/2 main jet covers all the rest of the range. Being that if you run your choke on you are restricting airflow....therefore allowing more fuel to enter the combustion chamber. if you were to drop back a size on the slow jet (pilot jet) you should be fine.

But Moose, if he goes down in jet sizes he will reduce the amount of fuel being added. Why would he want to take fuel away?

Were getting you there!!! LOL

ok Im starting to confuse myself!!LMAO I can phisically do it tell is another story. how about resetting the air mixture screw then instead of say 3 turns out crank it in about 1/2 turn to restrict a little airflow?

DUDE.. bring me your quad I can fix it!! my dad was a tv repair man he has all these cool tools I can fix it!!!lol
