Sparks Advanced Timing Key

A 5 gallon pail of U4.4 would be the biggest bang for the $70. About 3 to 5 hp .

[12345mrjeff]

what is U4 never heard of that and what do you do with it

[nyates450]

You put it in your tank. It's a high octane, high oxygen content fuel.

don't do that... its not gonna help you gain anything. Trust me... High Octane in an engine that doesn't need it can actually cause a decrease in power. Give me a list of the mods you already have so i can better help you. But DON'T buy that fuel....

[12345mrjeff]

i got a pipe and jetted and filter and got different sprockets on there just looking for some cheap power

Have you ever dyno tested U4.4 on a stock compresion engine?

No i have not... BUT... It is the worst HP for $ mod that he can do. If you have to buy that stuff more than once, you might as well bore your engine and get a Hi Comp Piston. and by the way, running anything over 97 in a stock compression engine is not advised.

[12345mrjeff]

well i do have a 440 big bore kit and a hot cam 2 but i don't have it in yet the guy that is going to do it for me is very busy working on other ATV so am just waiting for him to call me then it goes in the shop

I put a big gun revbox on my raptor 660 and it really helped the response time.
