opinions and experience on a few tech questions - Drag Pipe, 40.5 Carb

you will have to talk with matt about a inframe, on the gearing try the 15 tooth that will not be as high as a gear change as trying to launch in 3rd gear

Dont worry about if it will not pull 5th or 6th gear when you are drag racing the first 100 feet will normally win or lose the race so use the gear that launches the bike the hardest. trust me all the fast guys run extremely tall gearing.
MX/WOODS gearing is never a good drag race gearing, time and time again I see big cc MX bikes get killed by smaller properly setup drag bikes mostly do to tires and gearing.

You should be running the rear shock as hard as possible to plant the tires, and then use a adjustable link to change the height of the bike and adjust the angle of the rear swingarm. The more horizontal(flat) the swingarm the less wheelie, the more angle to the swingarm the more wheelie. If you are lifting the throttle because of a wheelie then you have already lost the race.

OK will have to try that wheelie is no problem in ever wheelie even on pavement I break the tires loose and the swinger I will have to change back I got a +6 stellar arch I think too long as of right now its sitting pretty parallel should I go with a full blown drag port ? Like was stated earlier

[rsss396]

I would leave the +6 swing arm on it but tighten the spring tension as light as you can and raise the angle of the swing arm by using a adjustable link if you still have the factory link style setup.  If you do not have a link setup and just run a shock like the Marvin shaw then increase the length of the shock to increase the angle of the swing arm. You want to make the bike wheelie just a little that way you know you are getting good bite.

not sure what type of surface you run on but paddles are for sand to loose dirt style surfaces if it's hard dirt then maybe some other members can recommend a good tire that can be modified some to work on dirt, I believe some people cut rows of knobs off MX tires to create better bite

If you are breaking the tires loose now, than the last thing you want is a high strung engine, that every time the engine comes  on the pipe, you are going to make the wheel spin issue worse.

Like others have said, you need to taller gearing (numerically lower). Taller gearing will "load" the engine and will make it less prone to excessive wheel spin. Also by "loading" the engine correctly you will get faster and you will enjoy riding it more

IMO there is more to being fast than just having a big engine. Set up your bike for your body weight.

Hope this helps
