2001 Yamaha Raptor 660 Engine Dies

[turbo833]

hi, im new to this forum. came here to maybe get some advice on whats wrong with my raptor. i have a 2001 660...i let it sit for almost 6 months without starting it. i charged the battery and it fired up, but it idles and when i hit the throttle it dies. so i cleaned the carb, put fresh gas and it pops and spits. it will rev up after it bogs for awhile, but it is popping real bad. and its popping at idle. anyhting else i should look at?

thanks

You probably just need to clean the carbs better. They need to be completely disassembled and every nook, cranny, and orifice needs to be cleaned. The air screws should be removed so the pilot circuits can be properly cleaned. The jets also need to be cleaned out well.

I agree with Dirt Demon, you should do a good cleaning. Here is a nice general how to: HOW TO CLEAN YOUR ATV CARBS

Dunno if it would work for you, but I put STP fuel injector cleaner in mine and it worked well!

make sure your parking brake is OFF. 01's have a rev limiter switch on the parking brake on the left control assy. make sure it moves in and out.

with the parking brake on it will bark and pop at you. If that little switch is stuck it will think the brake is on....handlebars, LH side.

it should run correctly with the switch closed, as in parking brake off.

oh be careful backing up the 01- there is NO rev limiter in reverse- it will haul butt in reverse and pitch you right off! LOL in 02 they limited it.

STP or race gas [a little] is a good idea to clean out misc crud. you have 2 carbs- buy a book before you go tearing into them!

Make sure your choke is turning off as well. sometimes the cable gets cruddy inside and you may think they are off, but not true. How: go to the left handlebar control and sit down under it so you can look up at it. Now work the choke control and make sure the cable is sliding smoothly and not wadding up under the lever. if it is, then follow the choke cable to the carb [sticking out, LH side] unscrew it and pull it straight out. It's a little piston. it may need a little emery cloth to make it slide smoothly in the choke bore. wrap some emery around a drill bit or pencil and slide it in the bore to clean out the white crud that gets in there. It's electrolysis- brass piston against aluminum housing. wish I had a nickel for every one I've cleaned.

Hold the cable up in the air and squirt some lube inside it while you're at it. this should fix it.
