Thanks for all the info, but unfortunately he dont ride in the winter, so we are just gonna have to wait and see what happens this summer, when it happens ill be sure to post the results, thanks again

 

He won't ride during the winter?

..You'll win either way like everyone else has said.

 

Why wont he ride in the winter???

 

Just wondering but who the hell does engine work before having a full pipe??? a slip on with engine work? that just sounds funny. He is modding his quad out of order! lol[img]i/expressions/face-icon-small-smile.gif[/img]

 

my cousin has a 440es, white bros slip on and at ported and polished head, and when i would race him with my raptor ct pipe and k&n, it was no competion, i could smoke if i wasnt even trying, i could get 5 lengths on him on the hill, i also weigh 250, and he only weighs 120. a well built 440ex, is very good runner. but it has to be very well built, and then it comes down to the rider, but if you buddy just has the drop in 440 with a slip on, dont worry about it, as long as your able to get traction your kill him

 

We have 5 ported polished, race cam, 440ex's that ride with us and my mom's stock raptor takes them most of the time (rider difference) but some 440's RUN EXTREMEMLY WELL and it takes a well built 686 to beat them... Totally depends on the combination of the 440's build and who built it... Some are extremely fast some run well...

totally depends... to many variables to give a definant answer of course...

 

I dont meen to get anything started here but its a differeny story in southern ohio, 440's put up a hell of a race to unstock raptors, and a stock raptor might as well not even waste his gas, There are some true 440's around here, and i meen not just the bore, everything else to go with it and there aint a good anuff runnin raptor around to run with them, but then again a raptor aint a high populated quad around here, never figured out why?

 

I'm going to get in, and say that you will beat him, like every one is saying, it takes a really well build 440 to perform good. But on the other hand, I've seen some 440's running on alky, beating pipe YFZ's and more. Very impressing.

 

I've seen 440's on alky beating 727's!!! an EX can be built to fly just not too many people own them. Then again I think I've seen some raptor riders that would probably been beet by a stock 400ex (rider experience/gearing)
