Has anyone built one of these for an unlimited class? I’m considering it for fun but can’t find a builder that will touch it. I saw on YouTube someone added a power valve and bigger carb. Seems like they should be good for 55+hp if done right.

we have one of those fitted on george"s kart and its a joy to ride . Tons of fun and torque , it kills instantly all of us with the 125cc inside the racetrack .
easy to service also , has no real difference with the x30 , but the parts are a little bit expensive if you put them near the prises for the 125 cc
Yeah IAME recommended only replacing the top end every 105 gallons of fuel for recreational use! Considering there are 125s without a power valve making 35-38hp (ok n and x30 s), it should be able to make at least 50hp. It seems very conservatively tuned from the factory.
Gallons or Liters? Gallons is huge!
Never mind, Google AI lied. It’s every 150 liters or 39 gallons. Still a crazy long time. It would take about 40 hours in my KA 100 to burn that. But I’m sure this will use a lot more gas.
Just ordered one this morning and found a builder willing to take it on. I’ll post the results/dyno and videos when it’s done.

Does anyone know the limits of a 219 chain? I wonder if they can even take 50hp.
You are not gonna have problems with the chain if its from a good manufacturer . Just more frequent replacement coz the 175 , eat those fast .
Read the above thread it was very helpful for us when we first meet with the 175cc
