Yesterday, Billy Musgrave (Factory Karts X1-23 / MRC IAME SSE 175) won Pro Shifter at the SKUSA Winternationals.
This is the first win by an American-made chassis at this level since the Fausto Vitello days.
The advantages Willy and Billy have found are designed and built into every Factory Kart. Come down and experience the difference at our manufacturing facility in Riverside, California.

That’s is a fantastic bit of news. well done. This is the thing about following the crowd… you’re following not leading 
I’m not taking away from what Billy did or how good the factory karts are, but iKart won a SKUSA Winter Nationals (with your same driver) and won a SKUSA Summer Nationals with Jesus Rios in 2015. So, be proud, be excited, but lets not get crazy.
Congrats! That’s quite an accomplishment and they are cool looking karts, too. Danny did a nice job defending in an earlier round, frustrating Billy rather well.
Why no torsion bars?
Glad to see a non Italian kart win
Congrats on the win! Made in the USA!
I miss seeing those little flags on everything.
I’m not sure why anyone would want to set up shop in comifornia, I mean California, BUT I am glad to see at least some American made products out there winning in a predominantly Italian based market.
Cali is a hotbed for karting in many ways, which makes sense given it’s origins.
I think the biggest asset and challenge for factory karts is Billy. He could probably drive a barn door to a podium. Interesting that it was on a 175 too.
With some time off between contracts at work I should probably put together a media/pricing kit for KP.
Is it really that interesting? That track looks like it makes the torque of the 175 shine.
Lots of stop and go, 175 was pulling stumps.
Not to mention as I understand it the rules for the 175 have been opened up so it’s now like a KZ1 with extra 50cc.
I can’t find these new rules. The last updates I can find to the 175 rules is the removal of the exhaust spacer and the slide carb.
Billy was using the Tillotson 34mm pumper carburetor.
Regardless of what carb he ran, those two changes are the ONLY ones I can find regarding the 175 rules with SKUSA, but people are talking about the 175 now being “open”…
I’m not super versed on the comings and goings of sse rules, but from what I gathered the lack of squish and ignition timing rules were definitely brought up. Can’t find them in the rules either. No idea when that was changed.
Ignition timing and squish is open in the main SKUSA rulebook, but that’s really it. There’s only so far you can go before it doesn’t help. Acting like it’s a totally open engine package is a stretch. You still can’t port, etc., and everything has to match the “fiche” that SKUSA has published.
yep Good Driver Curse. It’s almost a disadvantage to have a good driver on your chassis in karting, especially if numbers of said chassis are relatively low.
We’re looking for another fast driver or two and a very large number of ordinary ones to demonstrate how good our chassis is for everyone else - including me.
None of the changes allowed in the rulebook get us away from the limitation on the SSE: it’s a large-displacement, slow-turning, high-compression engine forced to run on a fuel that’s at least 2 RON short of Eastern premium e15 pump gas.
