has it been sitting for a long time with gas in it? maybe the main jet in the carb is gunked up? how does it look inside the tank? if its orange or red that is rust, you may have chunks of rust in the carbs.

when it first started i was riding it regularly and i stopped and let it sit for about 3 months then fired it back up today and let it idle for about 25-30 minutes and same problem with the throttle. gas looked alright, i did add a can of sea foam carb cleaner to it hoping that would help but didnt.

on top of that i took the gas tank off to get to the carbs and none of the freaking allen head bolts would break lose without stripping. lol its starting to get frustrating with all my friends out riding in the great weather

Sounds like carbs to me. Ethanol will do a number on the carburated system starting w just a week. Idle does not allow gas to flow through all the jets. Seafoam is great if used every gas tank etc. But the damage is already done.

W the screws, use some good pliers or channel locks to loosen the bowl screws. I have the same problem w my carbed bikes. Be sure to soak the jets, needles, clean out all the gunk and use wires to clean the remainder. Blow them out w air. Remember, nothing w rubber should be touched by carb cleaner.

Or, Motorcycles Unlimited has a great cleaning procedure that uses a parts washer until all the stuff normal hand tools cannot get off. Contact them for more info. GL!



Note: if you keep the choke all the way up and flutter the throttle, you can slowly unclog the junk in the mid/high jets. However takes several minutes and needs to be done each time the bike sits.

Thanks for all the suggestions guys! Cycle shack north offers a duni jet kit for 125 bucks do I have to get that to clean them or can I do it without a kit just breaking them down and cleaning it?

Jets are clogged. You are not the only one having that problem on that bike. If I remember the jets on that bike are tiny and clog easily.

Ahh good to know, is unclogging them a major project? I'm pretty mechanically sound but never done jets before, I'm on a budget and can't afford cycle shacks labor . Is the kit worth buying an doing myself or can I unclog them without a kit? Thanks for the quick reply!

They are not affected nearly as bad as carbed bikes.

If you've never "cleaned" your carbs you probably don't want to do it by yourself
the first time. Also you'll need to resynch when done.

A "Dynojet" kit isn't going to do anything for you. If it ran fine before, it'll run fine again after it's fixed. The DJ kit has parts for recalibrating the carbs for
changes to the motor, intake and exhaust parts.

Good Luck.

Also if the pilots are plugged it is usually easier to replace then then to try to clean them. A set of 4 usually runs +/- $20.
