Nice curve, Seymour's done a good job of that barrel. Wish you could have bought something like that back in the day rather than crappy old MBs and TSs.

Holly crap that thing has a ton of Torque from 8 to 10k! It wants to rev, thankfully something is holding it back. Its not the pipe, maybe those silly flappy things you have in the inlet. Thank goodness you don't have that cylinder on a rotary valve bottom end
You bastards are forcing me to do some more work on my air cooler

The 110cc rule change was supposed to force us to push these things to the back of the shed.

PS - if ANYONE can do a 125 Aircooled with 24mm carb and make anything like 30 Hp at 10500, then its here in writing - free blowys for life.

that is a good point .as a rs it revs to 14 max .think rs reeds go in it .forgot to try

you can't use RS125 reed block or petals. But test away, would love to see the result

That torque curve is certainly the big surprise to me as well, we still have a couple of adjustments to make up our sleeve, but the debate has raged over whether it should go on the MkII, or we risk it on the prototype. The GP is getting closer, and it may have to wait in case it wasn't to pan out.

Looks like the CNC magician needs a new challenge...

The current curve suggest a probable winner in Regans hands, especially if you have a clutch that can be slipped out of the Tokoroa hairpins. The shitty KE125 clutch is either off or on, that KR bottom end may just hide the key.
Sad thing is the KE is getting pretty close to being a race winner, but the current rider is well and truly past it. I think another glass of self pity maybe in order. Waiter, bring me my whine.

What reed block you using? The stock NSR250 ones will flow enough for over 40hp standard as you already know.

Maybe try adding a nice bellmouth / radius to the end of the carb if you haven't already. 24mm is a restricter for sure. Hard to imagine it revving much higher with such a small carb.

Not that you need any more HP but over rev would be useful. Observation based on what Rich just mentioned carbs that are to small auto enrich at high revs due to the velocity. have you considered a solenoid to reverse this effect? or using a low lead fuel that responds to too rich a mixtures at high revs?

Second one are you using a carb designed like TZ did with the venturi. Robs was based on the famous TZ750 restrictor that actually allowed the TZ to go faster and lap faster with a smaller carb.
