Any sprocket increase puts a strain on the engine, but 14 isnt bad. I never needed a larger front until I had cam, piston, pipe and filter. Even then it was only for a particular flattrack. If you really want to gear up that much (I cant imagine a useful reason why) then you really should reduce the size of the rear sprocket instead. Much less strain on the engine and you are less likely to have to buy a new chain.

I don't know how much faster, but it will be noticable! Pull out the baffle, take the rubber flap off under the tank/ seat, put in K&N and rejet... for about 50$ you will get a significant increase! This is the Easiest and Cheapest mod to make to a stock rappy!

What? You should not be running a 15 tooth front on a stock machine. You will lose all kinds of bottom end and it will take you a very long stretch of road to reach top speed. Most stock and piped raptor owners go with a 12 tooth front or equivlent rear sprocket. A sprocket that big on the front puts a serious strain on the engine as well. Its better to change the rear sprocket some as well if not for the entire change.

Yes, go 12 BIG difference over stock. [img]i/expressions/face-icon-small-wink.gif[/img]

first of all, don't be in a hurry. that will co$t you. research your parts carefully. i ended up putting a white bros e-series on, rejetted (gyt-r kit), new filter (gyt-r), removed the air-box lid, and put a 12-tooth front sprocket on. it is a new machine. you won't believe the difference.

Ya, I donno where you figured 15 but I'd say go down to 12 and get that acceleration and holeshot. A stock bike WONT be able to pull a 15 tooth countershaft sprocket in higher gears and the lower gears will bog very easily.

If I just pulled out my Baffle on my Stock Raptor would I have to rejet or would it still be a good increase with out rejetting, I also heard it will be way louder, How much louder should it be?
