I have an rxl that I just got this winter, and have had a bunch of problems getting to run right. At first it would run but with no power. I replaced the fuel filters, the plugs, the battery, the driven clutch & belt, and still no luck. So yesterday I got the idea to put a car battery in it, and now it rips for about five minutes and then it runs like it did. I'm thinking gas tank vent is not venting and i'm getting a vacuum to it after enough fuel is sucked out of it. Then it no longer has preasure like it should. Has anyone else run into this before?
Its not the vent it works fine and it's not a fuel presure problem I have almost 40psi. When i first start riding it will go like it should. After about 1/4 mile it seems like there is a loss of power. I don't think it has anything to do with the engine. Is it possible that the bogey and idler wheel could be bad? Could they cause a loss of acceleration after they get warm or something? I'm really at a loss here please help! Any ideas would be great.
