Honda CB125 - CB150 12500 RPM

Marshland@marshland.co.nz. I have been playing with this bike for about 18 months.
I have had a few blowups, but each time I learnt something.
I have completed 5 race meetings and it is going well.
Power output is in the order of 18.5 HP.

The bike produces about 18.5 hp at the back wheel.

See the new frame. About 160 lb

marshland.co.nz/CB150Frame.htm­l _Not sure how you make 120 lb as everything on my bike is made from thinwall tube and aly.. Maybe the slicks add to my weight.

It was Graham Harris's dyno but I now have my own one in the shed.

Are you running a standard cam profile? Doesn't sound like it?

HMM still think you will get humped by loads of125lc`s of the same decade , as the unrestricted versions were pushing 21bhp (standard) along with kawasaki`s AR 125 21BHP and yamahas 125lc . Been intresting , but i feel using what is basicaly a low reving CG125 engine was a bit of flogging a dead horse even when giving it an extra 25cc .

@deathmetaldude468 All engines run best at a certain RPM, 2 stroke or not, but its more noticeable in small and tuned engines. A stock CB100 kicks at about 6000 RPM.
