I just installed my t5 pipe kit with jets and new needles included in the kit, and I am using the 280 main jets, also I installed a pro design air filter kit with a K&N air filter with no lid and I was wondering if this setup would be to lean? I live in the central valley in california, But if I go to Pismo, will this setup be too lean? Toomey said that this jetting is good anywhere above 60 degrees. What's your opinion??

thanx

Too lean. I think you need to be at least 300 maybe 310 or 320 depending other mods. With my mods I need a 320 at sea level.

 

But here in the cental valley it 's running perfect, perfect color on the plug and I called toomey and they told me that with there jetting kit that I might have to go up to a 290 or 300 if the temps are below 60 degress. WYO?
