Alrighty i'm thinking about doing some work on my 4 wheeler during the winter months here and i'm think about a HMF slipon pipe, UNI air filter, STage 1 came (hotcam) and a 14T front sprocket. Now With a pipe air filter and cam will a 14T make it it down low? or will the 14T bring it in just right for the extra power without losing a bunch of top end?

You guys think its worth the 300-400 bucks it'll cost me.

those are really good mods youve chosen.

in my experience -

hmf - low end
hotcam stage 1 - low end
14fnt sprocket - low end
uni - all around

your bike will go the same speed as normal, it will just get there a lot quicker. cant really understand what your question is :ermm:

I guess i just was wondering with the extra lowend from the cam and pipe if the 14T would make it hard to find the right gear making them too low? I dunno maybe i'm just screw up lol.........

Mostly trail riding. I dont do any racing, just ride trails and ride around the farm.

i would just spend the $10 on the front sprocket and if you dont like it you can easily change back to the stock 15 in like 5-10minutes. im actually considering a 14t front also.

would a 14 tooth over a 15 tooth be a noticable low end gain?

Only reason I can see you running a 14T after your motor up grade is if your running 22 inch rear tires. I can actually run 22's just fine with a 15T but the 14T makes it better.

I'd run with a 15T first and see if you like it, then decide on the 14T.

I have two filters for the 400ex for sale. They are Twinair and K&N both are new. If you are intrested.

I would not get the cam just yet. Instead I would go ahead and get a complete HMF exhaust. You can always get a cam next year. If you eventually bore it to a 416 the complete exhaust will be a must. That would also be a good time to add the cam. But that is just my opinion.

I won't ever bore it.......... I don't know for sure if i'll do the cam or not. I might just pipe it and 14T front.
