Should I go down a tooth to clear big doubles?

[m4crampt]

I'm running the stock 49 tooth sprocket and I'm having trouble clearing big doubles and triples. I'm especially having trouble clearing the jumps right out of turns. Should I drop a tooth in the rear or just keep trying to clear the jumps with the stock setup?

Go up to a 51 tooth on the rear! I did and was having the same trouble your having and it is a difference between night and day, you'll love it:applause: and love the way it pulls from a dead stop in second. And dont forget to do the 1/4 turn throttle mod!!!! with those two combos it will RIP!

Amm, you don't drop teeth on the rear sprocket to improve acceleration. You add teeth. For someone jumping big doubles and triples, you should know that already!

If i were you i would go up one tooth at a time.

A 50 or 51 tooth rear sprocket, plus a different pipe that increases the low end. You could also try the zipty carb mod. Those three things should get you over just about anything, no matter how close the jump is out of the turn.

Are you being serious?

whatever, simple mistake

I assume you are twisting the throttle .... but I had to ask as a lot of riders think they are but are not

Try going up 1 tooth at a time on the rear....all depends on track conditions, size, length, tightness etc.... If you go up you do lose some top end, so going up too much can be bad, again depending on the track. You may clear every jump with ease but you may get spanked on every long straight....A 49 or 50 works as a avg baseline,,,,each track will differ on what gearing to go with. Supercross type tracks usually always mandate 2 + or more from 49.

Also any way to increase bottom will help. The Zipty mod, the 1/4 throttle mod a new pipe etc........the list is endless, just don't over gear it, you will be sorry:thumbsdn:

It depends on why he's having trouble clearing the jumps, doesn't it? What if the gear he leaves the corner in revs out too quickly, and the next higher one doesn't pull off the turn well because it's too high? You could cure that by going either way with the gearing. Depends on how the rest of the track lays out.

Thanks for all the help, I appreciate it. I'm going to try adding a tooth in the rear and twisting the throttle a bit more. A bit more gas couldn't hurt anything. Well, unless I hit the face of the next jump.

Thats when you know you twisted the throttle....completely

It really depends on how you look at it. If you are coming out of a corner and having to shift to 3rd and not getting enough pull as you hit the jump, you might consider reducing teeth as you initially said. This can enable you to stretch your gearing out which would let you hit that same jump in 2nd instead of 3rd which helps reduce your shifting and achieve what you want. The downside to increasing your teeth is you reduce your overall gearing which can cause you to shift a great deal on longer tracks. So alot depends on which type of tracks you ride.

In all honesty, most people can't tell much of a difference of one tooth on the rear sprocket (on a track) and the people that can wouldn't be asking if changing the gearing will help them clear a double.
