brunow - 007 Posted May 4, 2017 Report Share Posted May 4, 2017 Hello, So i'm looking for a spare engine for my TR35 Beta (50cc) The current engine spare parts are of Unobtainium or extreme expensive. The clutch is slightly worn out and i hope it will last some time. But i like the bike! So the idea is to run the bike for the rest of the season. And rebuild the bike this winter to twinshock & install new engine. AM6 / DERBI engine. +Lot’s of spare parts +performance upgrades. +Cost of a tuned engine quite high (70cc, good crankshaft, heavy clutch) -> 300-400€ + Engine size is quite the same, some welding required -Still a 50cc gearbox -> easy to fail -Water cooled (cost of radiator, non classic look) Honda mtx / Tml – Suzuki Ts x 50cc engine +Air cooled! +Engine size is quite the same, some welding required +Lot’s of spare parts +Exhaust exit in the middle +performance upgrades. (cheap) +Proven engine from the Tlm50 -Still a 50cc gearbox -> easy to fail -420 chain instead of 428 Suzuki AX100 engine +Air cooled! + only 22kg crate weight (with kickstart, carb & elektrics) + Square bore/stroke (50x50mm) -> 98.2cc + Low compression -> No chance of overheating while driving slow + 428 chain -> same as the beta + Low first gear ratio -> 32/11 + Cheap parts: Clutch same as Suzuki A100 -> 30€ new plate & springs Bigbore upgrade (115cc) 50€ + Engine size is quite the same, some welding required + Good price for NEW engine + Still produced for export markets (india, africa) proven engine -low power 5.9 – 7.8 BHP to start with (tuned 50cc power) -The exhaust goes tot he right instead of the middle. Any more? I like the AX100. It’s a heavy gearbox / clutch / crank with little chance of breaking. There is room for upgrades and they are cheap!
