The mods I have are in my sig, I also have a g-force axle on its way in. I ride ALOT of trails and plan on hitting the MX course a couple times this year to see if I like it (which im sure I will), im a finatic when it comes to jumping. So here is what I was thinking to give my motor a low-end bite. I would also like to keep the shee a sleeper (keeping the stock look).

 

Paul Turner mids (get them bare metal and powdercoat them black)

Head milled .020 (plan on running 94 oct whats the most I can mill?)

Cylinders ported .020 over (with wiseco pistons and mx port job by rb racing)

Crank trued and welded

Removing the lid

15/41 gearing with an o-ring chain (im at 13-41 now and the gears are too short for mx)

Maybe a 33mm single carb later on

 

Any suggestions would be appreciated. Once I get the pipes im going to send the guts out to R&B and see what he reccomends.

Timing advance +4.........then check compression to see if you need a mix of race gas. If the compression is too high (>150 psi or so), you can back the timing back off and stay with 94 octane. I had a head milled 0.020 and I had right at 150 psi, with +4 timing and it ran fine on pump gas, but that's borderline.

What have you already done to the suspension?

If nothing, leave the motor stock, get +2 +1 a arms, better shocks all the way around....

 

Mods are in my sig, I have arms and shocks.

I must be blind...didn't even see that when I posted earlier (you're not playin tricks on me...are ya? ) :rofl:

 

Are you going to be racing against other banshees in MX?

 

If not, you're pretty much at a disadvantage to a stock 450 on a track, out of the crate.

No im not playing tricks on you.

 

I will be fine vrs the 450s on the mx track. Im just going for practice days anyway. Im in school and dont have time or money to compete right now.

 

I have one friend with a shee that will be racing with me, other than that there is a couple 400's a couple 450's and a 250r that i know of.
