I would go with a Serval or low port Driveline set up. Go with a 421. My engine is in the dyno section if you want to look at what that set up can get you hp wise. A builder like Redline or Driveline knows the formula for their engines so they can set you up all the way. Youll need a pro mod transmission and billet clutch basket for the extra power along with the internal mods like high flow impeller, pancake bearing etc.

thank you

Im going to put a black frame and white plastic. I'll match the seat after that. Envoyé de mon SM-N975W en utilisant Tapatalk

Smh.... We are not using cv carbs ffs!!! The stock carbs are not cv carbs. The most popular carbs (keihin pwk, or airstriker) are not cv carbs. Envoyé de mon SM-N975W en utilisant Tapatalk

Claude, put a matching seat cover on that unit.

Try this with the eccentric screw first. Hopefully you didnt bend a fork.

There may be room for stacks in there.

You start running out of room for the filters and pipes between frame. Stacks would set em back farther yet.

Weird, i was just talking about this. I run 28s on a 421 serval and they are dialed in with the Snipers from Cam himself. He did have trouble with these carbs air screw adjustment. I have switched to Shearers and i cant get the jetting where i want them. I just bought 33 PWK from a guy running Driveline set up who couldnt get his 28s working either. This guy eneded up going 35s. Driveline seem to perfer 35s on their 421s, thats how id go.
