Drag Gearing

Im headed to the strip next week and was looking to get some imput on gearing. Last year i ran low 10s with my bike being completely stock the whole way around. Im looking to go 9s this year. My bike will be lowered, but still swb. My question is what kinda gearing should i go with. i was thinking about just going down a tooth up front, but didnt know if that would be enough. I dont want it to be too wicked or anything, but would really like to see 9s lol. Oh yeah btw im only 140 lbs suited up if that has any influence on gearing. Thanks in advance!

I managed 9.82 swb with only -1 up front. I think it could have used a little more, but I would start there and see how you do.

Oh and Im about 145 suited if that helps and get a strap.

I was -1 +2 last weekend running high 9's (I'm 230 suited) until I stripped the teeth off of my aluminum sprocket. With that setup I could run through the traps in the top of 4th. I'll be -1 + 4 this weekend (or until I get a new 41 tooth sprocket) and will probably have to shift to 5th.

If you can do it, I'd go the -1 +2 route - it's not too crazy and as light as you are, it should be perfect.

Start with -1... move up in steps. If you like that and feel you still need more gear then add to the back.

Also, unless your chain is pushed pretty far to the back of the adjuster... I just don't see +4 working out for you on stock chain.

Yeah im going to try out -1 up front see how it feels. I was just trying to get a handle of how far i could go. I know -1 up front will be fine with my chain, but wasnt sure if i could go up a tooth or two on the back without changing chains.

I was able to run -1/+2 using stock chain but I had the rear wheel SHOVED all the way forward. It was impossible to WOT 1st gear let alone launch hard. It wanted to flip badly and I weigh 200+ suited in leathers.
This was on a gen2 and I believe they have more chain length adjustment than other gens looking at the swingarm differences. -1/+2 may be tough on stock wheel base unless you are definately lowered and strapped. You'd be pointing at sky otherwise.

hey racejunkie im -1 +2 with the adjusters all the back in the arm. i went with a 112 link chain so i can use all the wb i could with the stock arm. you can do -1+1 with the stock chain but thats it. +2 will have the chain WAY to tight and very hard to fit.
