Is all that power from the Morini going into an NV hub??? Does it handle it? That is a wild mo-sheen!

Its still in the proving grounds, but yeah its working. Documentation on it is in the Morini section.


Phildo looking forward to seeing this run! Your the man! You know there is a slant head version of cylinder heads out there that provide better frame clearance for a spark plug? Thought I would mention it in case ya did not know? That bike is gonna prolly do wheelies! Love that thing

Alrighty, finished up a while ago but have been tweaking since. Have another 6 hour endurance Mopedathon coming up so need to do some performance improvements...

Also upgraded to a 3 speed hub. Although at this stage the 3rd (high) gear is not working. Will have to sort that out before the next race.

Its been up to 73kph with the rider in safety jandals and shorts. A little bit scary but thats just what we do here in NZ.

Controls take a little bit of practice with brake/clutch/twist gear on the left and brake/accel/kill switch on the right.

...and a few more pics.

Got a slant plug head on the way, apparently they are higher compression??..

Will also cut up the exhaust and make adjustable for length leading to expansion chamber (kinda like a trombone).

Me and a couple of guys are going to build an inertial dyno for better tuning.

Other than that ill just align the bearings, make everything spin nicely, and hopefully get it tuned well.

any other sweet ideas for improved performance?

got a bit of a sore arse. surprisingly had no problems with the engine or drive train over the 6 hours. came off once just after a bit of rain. it hurt (combined with the hangover at the time...) next one coming up in November. some guy has built his own roots supercharger to go on his water cooled 4 stroke 50cc. crazy.

gonna build a inertial dyno to see what power all the scooters are putting out. will see what this chinese engine puts out too.
