jetting

Elevation where I am located is 889ft. Was curious if stock mains would be an option with Dyna-Jet stage one needles and springs and drilled slides. Maybe moving the clip on notch to the rich side. The bike has K&N air filter and Super Trap slip-ons. It was running lean so I tried bumping the...

Hi guys. I am new to the forum and also to Vmaxes. I recently purchased a like new 85 all stock. I installed Cobra 4 into 4 and K & N filter. I plan to remove the "y" also. Does anyone have a recommendation of the main jet size I should try first. I am at approximately 1000 feet elevation...

Ok, Ok, here it goes I have installed a HMF 4-2 "2D9S" full system into my 2WF engine. I have had to swap out the 2WF Carb due to two of the Idle mixture screws being totaly FUBAR. It is being replaced with a 49 state Carb with Stage 1 needles and stock jetting; 152.5 mains, PAJ#1...
