Understandable on the Dyno. There was also another 250 dynoed there and it made 33-34, so it could be how he has the dyno set up.
No huge tricks for the setup. No airbox, Factory jet kit and area P exhaust.
Bone stock internals.

Do you mind sharing any power related mods? (airbox, oil weight, jetting)

what about drive train? You still have 520 chain? Did you go with aluminum rear sprocket? OEM wheels?

Another option is to run light sprokets and a non-o-ring chain. We did some research and looks like a light 520 chain works about as well as a 415, and lasts a bit longer.

So sounds like there is no airbox? Are you running a pod filter setup?

That's what he is doing. He is running 415 sprocket conversion with the non-o-ring chain

Pretty sure the kit comes with an aluminum rear sprocket, so you save good bit of rotational mass there along with the mass of the lighter chain = a little more power to the wheel.... but how much is the question?

Yea...I'm pretty sure all the builders are calling bs on this one. those mods would be about 32 at best.

Good looking bike though with a nice looking paint job. Glad to see this coming along.

Go easy guys, it's not my dyno and I did not calibrate it. Those were the numbers.
Another 250 with air box got 33-34, so maybe it's a little high I dunno.
To compare my superbike sv made 95hp. Which is right about where it should be for the mods I have in it.
Ultimately I'll see how strong this is in two weeks. I'll let you know how well it pulls.
