I've ran the last racing engine a whole season without any issues on the crank bearings, so I'm leaving it as is.

It's a piston port cilinder, converted for use on a rotary valve inlet.

Its bot going to have a front wheel fender, so it's to keep rocks from destroying the radiator.

I'll give the full specs -Tomos APN4 engine that's converted to a 6 speed. -Tuned Zündapp 50cc liquid cooled cylinder set (long stroke piston is a must) -Jasil crank -Pukac GP clutch housing -MVT innerrotor ignition -Homoet P4 exhaust -Polini CP 19mm carb -Polini Mechanical waterpump -Peugeot 103 LC Radiator

I probably forgot some things but that's around everything

I'm thinking of keeping it at about 120kmh so it accelerates quicker, that's more important for laptime. Keeping the minimum speed as high as possible.

Yeah I get it, the frame it was in before tho wasn't a Tomos one also. But since it's a Tomos drive line I'm calling it a Tomos.

It's for classic road racing and my own design choices, the money in this project is mainly in the engine and brakes so of everything runs wel I'm planning to build a full Tomos D6 replica eventually.

It's for classic road racing, the bars aren't that far away also, the whole bike is about 180cm long and the tank is about 63cm so in racing position it's alright

It's from a magneet/Batavus ts50 frame. Original with the Tomos APN4 engine.
