Can anyone help with gear selection for a kart?
What I am wanting to know is like for a certain size track, what gear to go with to get me in the ballpark.
And what # of the teeth on the clutch is a good all around to adjust with. I have several # of sprokets in cataloges and dont know what to order.
Any help with this or any tips to a NEWBIE kart racer will be greatly appriciated, Thanks.

Well in karting I have learned that one gear same track never works.On 1/8 mile high banked we use anywhere from 13clutch 63-68sprocket.The best way to adjust is to remember that 1 tooth on the clutch is equal to 4on the rear.approxamatly.Example 13 and 64 is almost equal to 14 and 68.But also to remember 200 rpm to a briggs is everything.So if your engine builder say take it to 6700 find the best combo that will do that.Sorry there just aint no simple awnser to the gear selection thing.

I have a 13,14 and 15 clutch drums.A 12 would also be helpful.In sprockets I have 56,58,60,61,62,64,65,66,67,68,70,74and 75.Generraly on most tracks here we run 13 and 62-68.Hope this helps but we dont travel much.Mostly 1/8 mile high bank and 1/10th mile flat.

If the track that you are run at has a lot of banking than i would start out at about 5 on the left and 6 on the right but if there is no banking that you need to run a little more air in the right rear to keep the rim from digging into the ground so i put about 5 in the left, 7 in the right rear and 6 and a half in the right front. I hope this helps.

Well it really depends on banking,stagger and set up.But tyler is in the right direction.I mean he has a good feel on things.Those pressures work for him and these are what we run on high banked lf 5,rf 6.5-8psi,lr 6psi,rr 7-8psi.But it all depends.But tyler and mine numbers will get u in the ballpark as to where u need to be.And remember the best thing u can do is scale the kart!!That is an absolute must.No if ands or buts.!If u dont have good scales buy good bath room scales.I have a few tips on useing them successfully if u need them.
