You got 26mm Mikuni's on their now..AKA stock carbs. Your going to bump it up to 35mm? SHIT YEAH your gonna need to change your jetting. My advice would be to buy two of every size mains for your carbs and a few pilots so you can tune the bitch..yeah it'll cost ya more but you'll never worry about not having that jet you need.

you will need to rejet. any time you add more air you will need more fuel.

I went from a single 35 to a single 38 and gained topend.

A little softer on the bottom,but still better than stock carbs.Definitly better than the 35 by the seat of pants feel. GPS showed a gain on the top, average 3-5 MPH faster. Hoping to dyno with both this winter.
