That Suzuki 200 is making 22ft lbs of tq stock with a 30mm carb. That's like 4ft lbs more than the current 250 4stroke

Its more of not listening to screaming little 125 engine. Because the either 2016 or 17 the motrex motors shared by husky,gasgas,ktm,125's etc are capable of 45hp at the wheels. Found this engine will definitely need a much larger expansion chamber than a 125 https://youtu.be/WNjy6vsP5Yg?si=kgh9krjPHfJRAMQT 200cc Suzuki 2stroke may have had powervalve problems but its making as much or 4...

A sleeved down 2002 cr250 is.gonna be too big for a 125frame. I need to find out if there's powervalve problems with the susuki is making 22ftlbs of tq stock with a 30mm carb. I found this healthy 150psi bike with a 33mm carb. But its not that rare anymore https://youtu.be/d93hQ8YO4Zc?si=7zUA25AbUeTUYE0N The newer yz200 he got rid of it because...

You could very well be right. But its gonna be a trailbike with way too small of carb which makes it run well on the bottom end. As you can see they sell a race 35mm carb already japan.webike.net/products/27427.html

Thank you for clarifying that. I wasn't planning on racing it. I was thinking about setting it up in a full race trim and having a expansion chamber can make or break a motor made. Im trying to find out if the factory race team had tinkered with it like the ktm200 It is making 22ft lbs of tq stock...

I'll probably just mess with this thing

Ya, that valve probably kills the engine as far as max hp. Theres said to be another version that makes 34hp, probably in a ported raised compression form it also says it was a competition motor but you can't trust what the net says 60 percent of the time

It doesn't look like a real performer, doesnt appear to have a powervalve. It was made till 1998

Do you happen to know if the top end of the 98 will bolt on to a 98 125 bottomend?

I have a titanium lite 2008 rm125 frame laying around
