what is the top speed of a 250EX if it is pinned? does anyone have a DG xccelerator on their 250EX? how much faster and power does it add!

 

I don't have a DG xccelerator but I have a full race Big gun exhaust system and a K&N air filter. My 250ex will go 54-55 and the revlimiter starts kicking in. I think the Big gun exhaust system is worth the money it adds alot of power. My revlimiter kicks in and I weigh 180 pounds. I raced a blaster that has a fmf pipe and 18 inch tall tires. The kid that owns the blaster only weighs 115 pounds. We raced about a quarter mile and I only got beat by about 4 fourwheeler lenghts.

 

The 18 inchers had ALOT to do with that.

 

does smaller tires make a 4 wheeler faster or slower?

 

it decreases top speed but increases acceleration.
