Make sure it is tuned correctly. After that check your clutch, fuel lines tank etc...

Questions??

I checked every thing you guys said and there is only one thing that i saw that i thought might be a problem. there is a set screw in my center diff on the front side and when i turned it it wasnt tight so i tighted it but i havent ran it sense. do you think that this could have been my problem?
THANKS

If that is the set screw I think it is... That is a set screw that allows insertion and removal of the pin that the Sun gear sits on. This would not cause a problem from being loose. It just needs to seal the hole not really hold anything.

while its apart you should put some aluminum shoes on there, your get a little more bite outta the hole. Ive got a hyper 7 and it came with plastic shoes, so i bet yours did too.

Yep throw the ofna silver shoes with 1.0 springs on it and a Dynamite 086 pipe..It really wakes up that engine. That .21 is hands down the strongest 100 dollar engine on the market. Very well made too. I ran mine on Byron's Gen 2 30% race with O'Donnell's purple sport plugs. She screamed and ran nice and cool.

I can vouch for the engine as far as it being a screamer... Im still using the stock tuned pipe on it and no one can pull on me down our long straight. Its very quick out of the corners too!! But be prepared for it to run on the warm side... Mine is happiest around 270 but it is a Picco so thats normal lol

Default shoes

The ofna ones are 24.99 and will come with the black springs and gold springs.The black springs give great bite but the gold ones are for even more bite so you would just use the black springs not the gold.Hope this helps.kevin.
