Arrow Ok well then

I am having a little trouble with my bike. In second gear with the throttle in the same place the bike picks up speed. It is kind like it is all the sudden getting more fuel. Any Ideas?

Surging could be air leak on the intake/carbs or it could be an issue with the vacuum diaphragm in the carbs.

Thanks for the info. I will start by checking my carbs.

My bike does this a bit before the engine has fully warmed up. I always assumed it was normal/nothing to be concerned about. The surge I experience isn't something that I cant compensate for (mine is very minor... its not as if the throttle has gone from 0-100% on it's own... sounds like yours may be more severe) when I know to expect it. Once the bike is warmed up throttle response levels out.

How old is the clutch and when was it last adjusted?
Is intake and exhasut stock?

it seems to be worse as the motor gets warm. I just traded for the bike and am new to riding. meaning that I don't really know the answers to the questions you asked. I am planing on changing all the fluids this weekend. I am have some experience working with motors but nothing of this type. It almost sounds like I can hear air leak by at the top of the motor by the carbs, I don't know if that is normal or not. Thanks for you help, it is greatly appreciated.

Default Not sure you are getting help here

Read several of the responses and can't quite figure out what the oil has to do with the throttle issue, or the clutch for that matter. If it is gaining speed, the clutch has to be out all the way for it to engage.

Unless they are saying that it wasn't completely out and was gradually letting itself all the way out, which WOULD allow for an increase in speed as it disengages.

This could be a sticking throttle line, sticking enrichers, and, I guess, a sticking clutch. Grease all your lines, blip and release the throttle (you don't have to have the bike running to do this) to make sure it is free and returns to it's original position.

Meanwhile, I assume that you have taken a motorcycle safety course (?) or something that assists you in learning how to ride. Those guys usually will also assist in figuring out these kind of issues. Making friends with local folks that have experience and TOOLS is a great way to spend the afternoon and for a six-pack of your favorite brew, you can get alot of information and skills.

Enjoy! Oh, a disclaimer is required, "don't drink and then drive."
