To Mod or not to Mod...?

7 posts in this topic

Any suggestions on what mod. I should do next? Just looking for a little more horses, because I use the bike for Supermoto. In the dirt it was fine stock.

05 WR450F current mods:

YZ Throttle screw

Gray wire mod.

AIS removal

Zip-ty fuel screw

Yosh full exhaust /w header

Airbox opened up

Twin Air air filter

Jetting: 165 Main (#4 on clip), 48 Pilot (it maybe a little lean...I think)

I'd say you're pretty much golden with what you've done. Not sure what else you can do. What is your gearing for S.moto?

Right now I am running the 14 in front and a 47 in the rear. I don't need a to go smaller in the rear that is for sure. Do you think a 48 or higher may make a difference?

Ya, I guess not much more I can do unless I starting putting cams in and that may not make much of a difference and I am not sure if I need to go there right now. I do need to open the airbox a bit more. I have the side cut outs cut out and the snorkle out, but I ran it without the side cover and it was very noticeable the increase in most all ranges.
