what size rear sprocket??

[Silver400EXinBR]

if I get a 16 tooth sprocket in the front what is the smallest rear sprocket i can get?

The rear sprocket is the same on all honda sport atv's and even some 250r atc's. I run a 36t that's the smallest I've found ,36-44t is the range they come in.

IF I run a 16/36 set up i know that will help my top end alot but how much will it eat from bottem end... I mean will it be critical if racing 100 yeards or so? WIth all my mods in my sig. what do yall think it would do? And what do yall suggest to gear it as.. I tried 14 tooth front and stock rear and I mean.. I got beat by a stock 400ex with a pipe... not off the line but after 4th there he came... I sure dont want that.. I want something I can just roll by onceI hit 3rd, 4th and 5th...

There are 34 T sprockets. But I don't see why you would want a 16/34 gearing unless drag racing. If you plan on doing some trails and drag racing you may want to look at a 15T and 36T rear. You will get beat by most anything until 5th with that high of gearing unless you have some pretty good mods.

so with 15/36 i will do good with drag racing and top end as well?

It would be my guess with your setup. I dont have a setup like yours so I couldn't say. Depends on what your head work was made for. Question is are you going all out drag racing? If so 300' drags? Or longer? What you may want to do is Purchase a 36T rear which will run you probally about 20. A 15 and 16T front. Fronts are pretty cheap like $10. And see what one you get better times with in your lenght of drags. If you are doing 300' id stay at 14T.

I played with a 16/36 gearing a while back to just play around with top end. I have a similar 416 but with JE 12.5:1 piston in it. It may have lost some bottom end, but it sure did pull in the top-end. But I'm not sure how it will be in a 100 yard dash. I've been at 14/36 now for riding in the dunes. I was playing around with a friend and we were doing some straight drag racing with that setup and it was useless. It would reach top-end in at must have been about 65 yards if I had to guess (again this is in dirt). I know renthal makes a 36t rear but there site says they don't make anything smaller than that. Then again, it says they don't have a 16t front, I know for sure they have one b/c it's sitting in my roll-away.
