Atomic Monkey Posted July 6, 2014 Author Report Posted July 6, 2014 Does anyone know if UPP part # 1106 is the one for use with the crossover tube? Having problems finding that out on the Googler... Quote
slobanshee Posted July 6, 2014 Report Posted July 6, 2014 Why not remove the crossover all together Quote
Atomic Monkey Posted July 6, 2014 Author Report Posted July 6, 2014 I want to keep the crossover. Maybe its just being anal-retarded about things, but I think it helps buffer the intake pulses and aids in keeping the airflow across the jets more consistant at lower RPMs. Also, I set the cylinders up individually, and the adaptors I made for my sync gauge fit real nice in those ports with the crossover removed.

Atomic Monkey Posted July 6, 2014 Author Report Posted July 6, 2014 Anybody remember the days of "Roost Boost" and the Yamaha "Energy Induction". I was surprised to see a stock "boost bottle" on a newer Rotax 600 when I helped rebuild some carbs last winter. Seems like its more than just an aftermarket gimmick if OEMs are doing it. Granted, it won't really do anything if you run WOT all the time. Quote
Nightmare Posted July 6, 2014 Report Posted July 6, 2014 My 35 PWK'S never hit with UPP's Neither do my Mikuni 41's It's the billet intakes that are the problem. Get the UPP. Agreed, next intakes I buy will be upp's. Imo the wicked motorsports intakes are probably as good as it gets when it comes to billet. Quote
