The exhaust might restrict it some.
It's quoted as "Making a peak power of 17.5 HP at 12300 RPM when used with the correct exhaust system 21mm or above carburettor."
Probably 10-12hp then.

I would hazard a guess of 3-5hp You have been buying too many of those stock 60MPH Chinese scooters. It's made you jaded  |

I agree with AeroxBud...shooting for 12 is a good goal. I am curious about your stated air-box insert. What is a "high flow insert"? Pictures? I do my own air boxes for 4T FI engines, but 2T air box mods are not easy to gain results. Keeping it though is smart.

Update from the dyno: Hk = 15,1 at the wheel, with 13500 rpms Top speed = 86,99 mph It did pretty good I think  Not blue printed or anything. I tried opening up the stock air box a bit. It gained a little top end, but the loss of torque in the bottom end, made it not worth it. |
