just bought my son a 2004 txt 50 boy and it runs great until its hot, say 15 mins riding ,then it will not rev correctly and sounds as if its either missing or running out of fuel and also has no power. If I stop it for 3 mins then kick it into life it runs great again for 15 mins??? Has anyone had similar problems with this bike? Oh and while i'm here does anyone now which friction plate I must change to enable the clutch to engage sooner?

Hello everyody, I have just bought a beta 250 after watching trials for a couple of years, only been around the garden so far but by God its a damn site harder than it looks, fair play to you all out there. I am now looking for a Beta rev 50 for my son as he thinks I look like a complete fool trying to balance and thinks he can do a lot better!! if anyone knows of one for sale please drop me a line.
