hya, well ive jsut got a 12 tooth front sprcket and i was wondering if in a drag against someone with the same riding ability but 13 tooth sprocket, how much would i win by?and what speed will my raptor top out at now?also i was thinking that i would be faster round tracks and trials now right?cheers

 

Its still going to come down to rider...you should get him in 300 foot drag..But he will slowly start to pass you...Dunno about your top speed really..All i do is sand drag 300 foot so im running a 12-44 gearing...Im in 4th at the end of 300 foot...but if you still have stock gearing on the back it sould be a 38 on the back...so you will be running a 12-38 and your buddie will have 13-38...its not that big of a jump...I think in 300 foot it will be who ever gets out of the hole first...

 

hmmm stock rear is 40, erm i prefer using 12 tooth though, pulls out of corners a lot better without any downshifting.i'll try find a 13 tooth raptor to race, see how i get on there

 

lol my bad i was thinking the stock gearing for the back was 38..sorry
