Hi Vinny,

Vinny:  if i want to convert my regular pipes to drag. how much rejetting do i have to do

Mark:  DynoJet carb kits are available to compliment aftermarket pipes. Look a into Stage 1 jet kit with V&H pipes. Both are easy to install and include all necessary instructions. Basic hand tools are needed.


Vinny:  what is the difference. performance. high . medium or low speed performance .

Mark:  When properly installed, the Stage 1 kit gets the carburetion very close. I find little tuning is needed.


Vinny:  do i have to keep checking the plugs.

Mark:  Sure, especially after installation to know if the jetting correct for your MC. After that, just check plugs according to perodic adjustment table in the Owner's Manual. Keep the plugs clean and properly gapped.

If in doubt about this task, have a pro do the work. You can booger up parts if you're not careful.

Respectfully,
