High Elevation Jetting Set-up Help
Posted May 28, 2013 - 05:28 AM
Currently ride from 0' to 1000' elevation
Need jetting and total set-up advice for 8,000' - 14,000' max (Colorado Rockies)
Most of our riding will be in the 8k' - 10k' range
Lexx Exhaust with spark arrestor and 34mm outlet
No Toil air filter
All free mods done
Thanks in advance!
BTW, any other hints/tips for riding in the Rockie's would be great too!

But your current jetting probably works OK at up to 4000, so call it good for 2000 feet and go about 8% leaner.
Needle adjustment MAY be necessary, but as the needle meters fuel already metered by the main, you might not need to lower it.

thanks fellas, i got the JD jet kit, adustable fuel screw and a few extra jets.
running 15/46 gearing with a rekluse z-start pro, it's been working awesome in the tight stuff, climbs and equally well on the road stints
Run 16/50 for longer chain/sprocket life. Make sure your engagement is set for extra hard extra low rpm to keep bike cooler

Red needle clip in 5th slot
Fuel screw 1 1/4 out
Since I'll be riding between 6k and 14k feet elevation, would it be smart to add an adjustable vent to the airbox to allow more flow in the higher elevations?
I was looking at the TPI adjustable vent with prefilter.
