Mine is still in transit, it was probably a better idea to order it from the international warehouse instead of the European....
But a clubmember did get his one and did let me work on it
(it is the onroad version)
The engine is published as a super long stroke but the 16.2mm diameter of the piston shows a normal long stroke model. The timings are not bad for an offroad model but for sure the exhaust is far of from an onroad model.
In this list what it original had and what it did become.
The crankshaft looks good, with a 9.8mm hole and a large timing it is set to performance. Als doing some grinding on it it shows it is not that soft.
The carburatot is an onroad type but is set to a max of 8mm which is also not onroad worthy, I drilled it up to 8.5mm
The only thing I noticed was that it had no hone profile on the chrome layer (crossed scratches)
Some pics if the motor and work:
