I seem to be getting very mixed suggestions on what octane to run in my Superjet. Please vote and help me decide! :) Here's my setup: - 735cc Ported 61x cylinder, ported 62T case - Speedwerx High Comp Head with 35 cc Domes (the domes have a pretty wide squish band ~17mm and my squish is set to...

Ok so here's the issue. @BRANDO6X and I both have 701 engines for our SJ's, which we presumed the cranks were identical so we both ordered new billet couplers from epic. The issue is both sets fit on my crankshaft as well as his oem coupler. However neither billet coupler sets will fit on his...

Hey Guys, I'm hoping you Driveline ninjas can give me some advice. I'm currently going to be running a 08 superjet impeller on my 735cc with ported 62t cases and 61x cylinder, msd enhancer, light weight couplers and flywheel, v force reeds, high comp heads, dual 44 carbs, factory pipe & 85mm...

So a @BRANDO6X and I are trying to figure out if we need a fuel line restrictor (with changeable jets) in our return fuel lines or not? We are both using SBN44 carbs with the stock/oem fuel restrictor build into the return port of the carbs. We are both going to be running a/m pipes (b pipe and...

Looking to make a custom electrical box for my RN build and I am wondering if anyone knows the wire gauge(s) on a superjet stator harness and the start/stop switch harness? I'd measure it myself but I'm not at home and wanna order up some connectors ASAP. Thanks guys!

So I am currently in the middle of my ski build (link below), and would like dump a little more money into it to give it that little bit more oomph. I'm trying to decide between investing in an Advent Ignition or a Solas 12Vein Mag Pump and Skat Hooker prop? My goal is purely freestyle, mostly...

Hopefully you guys can shine some light on this. @BRANDO6X asked me to post this of his Nynja Head pipe. As you can see there is some sort of wire or nail or something in this pipe. From my understanding this is a brand new pipe never used, we sand blasted it so it could be powdercoated.

Ok guys, so I finally took the plunge and upgraded from a 95 Kawi 750 to a 96 RN Superjet 701. I ended up buying it in the spur of the moment because it presented itself as a ridiculously good deal. That being said I haven't even heard it run and I'll be honest I didn't know much about these...
