Web 384 vs Duncan X1

[YamahaNutz]

I'm going all in on seeing how much power I can get on a stock bore size.

Raptor 350 with a 11:1 piston, ported head, FCR 37 on a custom full bore intake adapter, HMF muffler.

Got a knock-off Ninche cam, currently. Looks to be similar to a Hotcams stage 1.

I ride full throttle, everywhere. I run out of high rpm power very quick. Sand dune riding is what I want to aim for.

Deciding between the Web Cams 384 and the Duncan Racing X1. Both are similar, but if anyone has any experience, or more insight, I'd greatly appreciate it.

Also already have Kibble White valves and springs.

My opinion the best with your setup for power would be the megacycle .450. I would probably switch to the 39mm fcr as well. That setup will put you in the low 40s but you won't have a lot of torque off of idle. I had the same setup but just recently put the smaller web .430 in it to bring back some low end.

Actually that Duncan 252x1 is the megacycle .450.
