Just got done cleaning my carb and the engine still bogs down in everygear and in neutral and has a hard time staying alive at 1/4 throttle. I put carb cleaning liquid in my gas tank and let the bike run for a good half hour. then i went to rev it and some black smoke came out of the pipe and then it went back to the normal exhaust color. I changed the oil and it is still good so i know the oil is alright. Any ideas on whats wrong with it? it also back fires through the carb and into the airbox like hiccup at 1/4 throttle

Thanks for the help

 

You didn't say what year it was, but if it is a 96 or newer, it could be your brake safety switch is bad, which kicks in a rev limiter, and barely lets you get above idle. Look for some wires running up to the left side by the parking brake, there is a plug that can be taken off, if that fixes your problem, leave it off or get a new one. A lot of people,like me, kept frying the rear rotor on the 95 Wolverine, so they put it in to keep it from happening again.

 

it a 99 there are i think 3 wires. witch one disables it?

 

I have a 95, so I don't have these wires, but I'm sure one is for the start in gear switch, follow the wires, two of them should go to a plug somewhere,just unplug and tape it off, sorry I can't be more help, I just know about the switch,not exactly where it is.

 

what about the backfire through the carb the e brake wire would'nt cause that would it?

 

sounds like the problem i had with my 03 wolverine. the boot was off of the front of the carb a little bit. put it back on and it runs like new. you might look to see if its off or cracked.

 

See, now that's something I wouldn't have thought to check, the 95 Wolverine has a bolt on carb, like the Warrior, in 96, they switched to a CV type carb and a different intake. Mean, do you know where the parking brake plug is?

 

It's a good idea to put another clamp on the motor side of that boot. Mine was sucking a little air.

 

not sure where the parking brake plug never had a problem with it so i never messed with it .when i bought it the dealer told me not to use it because it didnt work after the first couple of times anyway.

 

If you figure out what is wrong with your please letme know. I have tried everything with my 1997 yamaha wolverine it has the same exact problem your describing I've tried the cleaner also made no diff. then I pulled the carb of ripped it aprt and cleaned everything by hand and adjusted the valves also put in new plug checked output of coil and so on.
