It's a 350J pipe. Jetting was last set at 180 main, 52 pilot after some dyno tuning. Was thinking about boring the carb or looking into a Lectron possibly.

Engine and Bottom End / Sphinx TRX363R HP Numbers

« on: October 12, 2022, 12:12:07 PM »

Looking for some guidance on this. I recently built a Sphinx 350 cylinder with 4 mil stroker(363) with MX port, V-Force 3 reeds, Keihin 38mm A/S carb, OEM intake boot, open aluminum airbox, LED big bore pipe, CR Ignition. I love the motor, am very happy with it and am not trying to bash the builder or anything of the sort. I trust his work and experience but was told it would be in the area of 60-65 hp on his dyno. When I had it put on a dyno locally it made 53 hp. I understand each dyno can vary with different results but was not expecting that much of a gap. On the track it does feel a bit under powered when compared to the 450s. Just looking for some guidance on what I might be doing wrong or where I could gain some extra hp such as going with a bigger carb, aftermarket intake, etc. Thanks

Looking for a kicker knuckle as mine is stripped. Are there any other kicker/knuckle combos that would work such as TRX250X or TRX300..etc? Thanks

Engine and Bottom End / BDT Extended Clutch Arm and Cable Guide

« on: December 27, 2021, 06:15:08 PM »

Is anyone running the BDT extended clutch arm and cable guide? Do you have to notch the cylinder for cable clearance? My clutch was completely rebuilt last year but is still pretty stiff and wondering if this would help. Just looking for some feedback. Thanks

Carburetor, Intake, and Exhaust / Turbo Blue Race Fuel

Has anyone tried running this fuel in big bore motors? I've been running VP C12 but its pretty scarce right now out my way. Looking to start the break in process on the Sphinx 363 motor this weekend but all I can find is Turbo Blue. Was told it is 110 octane? Any input would help. Thanks

Everything was disassembled as I'm doing a fresh build. Calipers have been rebuilt but not recently.

Suspension and Chassis / Bleeding Front Brakes

« on: April 19, 2021, 08:47:15 PM »

I'm in the process of troubleshooting the front brakes. Got them to where they will pump up and build pressure but once I let the lever out for 2-3 seconds, I lose all pressure. Not getting any air bubbles out of the bleeders and I also tried zip tieing the front brake lever over night with no luck either. I did replace all crush washers on the brake lines as well. I'm going to try re-building the master cylinder next. Anyone have any other suggestions or have this same problem? Thanks
