Toomey T6 pipes

[gatoman28]

Hello, I need your help.

 

I bought a T6 toomey pipes with the 2:1 HFFS, instead of using the foam filter they sent with the kit I used the KN filter #RU0210. When I rode in Glamis I felt that I had to use more throttle when taking off from a dead stop. Does anyone have an idea on what might be happening???

 

stock motor

Toomey T6 pipes

main jet 280

KN Filter RU-0210 / one on each carb

Pilot jet is stock not sure what number yet

 

 

any help is appreciated

Just did my neighbors 05. We ditched the AB lid and went 300 mains, moved the needle clip down one(fourth down from blunt end) left the stock pilots, and turned the air screw out 1.5 turns. Runs pretty damn good for being otherwise stock.

 

Try this and I bet you'll get better results.

You are running lean in the pilot jet curcit. You need bigger pilot jets. If you ride under 1500ft use #30 pilots. If you are over 1500ft try #27.5 pilots.

I'm going to stick with what I said when you posted in Repairs/Mods....

 

This may very well get moved to the jetting & exhaust forum, but.... My opinion is that you are jetted too lean.  I know Toomey sends the "Perfect Jet Kit" with 280's, but they send those jets with the kit that does not replace the airbox as well.  I've never been there, but I believe Glamis is at or below sea level correct?  When I intalled my T5's with the 2:1 from Toomey (using the UNI filter that came with the kit) I ran 320-330's depending on the temperature.  A friend of mine with the same exact mods, at the time, was running the 280's that Toomey sent, and he had a significant loss in power. We rejetted it with 330's and it ran like a champ.    So, you probably want to jump your mains to somewhere around 320-340 depending on elevation/temp. Did you switch to the Dynojet needles at the same time also? If so you'll probably find the fourth or fifth clip position (from blunt end) to be very close. You may also need to bump the pilot one size to 27.5, but this can really go either way. Hope this helps, again I am running T5's, but jetting specs seem to be real close from what I've found.

 

edit: Sorry forgot to mention that my jetting figures for my bike were at sea level, approx 60 degrees.
