99 blaster looking for the most power.

[Gcorey82]

The work done to the bike is. Fresh rebuild bored .20 over with wiseco piston. Full fmf exhaust. K&n air filter lid not modified yet. Looking for a direction with carb work and reeds.

VF3 reeds are most popular. you really need port work and head rechambering, with about a 30mm carb. OKO makes a knock off of the kehin carbs, pretty nice. you will need a cap and cable with it.

i had the head work done when i had the engine built.

Have you rejetted for the pipe yet.

 

[Gcorey82]

Haven't done any carb work yet. What size jets should I use if I also remove the lid?

im feeling around a 280-290 but you need to check your plug to be sure. if it were me i would start at 290 and work my way down

 

[Blaaster]

Gee I sure hope you have not ridden it yet!

Dont forget to do heat cycles, and easy riding when you break it in.

When you re jet, do plug chops to be sure you have it right.

The bike runs great. Been riding since summer. No problems. Just want more power

What size main jet are you running?

You state that you have done no carb work, did you rejet for the FMF, if not you need to before you do damage.

You can gain some power with the FMF in the low/mid range, with a reed spacer block between the reeds and jug, and a +4deg timing mod.

 

[Gcorey82]

So what I've gathered I should be running around a 290 jet and +4 the timing and remove the lid. What kind of power do you think I'll gain?

 

[Blaaster]

Its not going to pull your arms out of the sockets, but combined with a good set of reeds it will be noticable.

15.5289% increase now take the lid off the airbox and rejet before u blow it. If you really want some more out of it send it off to get ported
