Dear forum,
Assembling the engine finally once againg. Had to dissamble it when the TW200 crank connecting rod bearing went bad. Got off ebay a used XT225 crank and a balancer to go with it. Had the crank rebuilt and now assembling it back together. The case is originally a TW125 and to fit the balancer i had to replace the left bearing with another one with same outer diameter but bigger inner diameter. The crank fits without modification. Cylinder opening have been machined up to allow 225 sized cylinders previously.
Windage house prevents oil splash from being directly sucked out vent on 125/200cc
Waiting for a new clutch lock washer before i can proceed...![]()
Yes, the ventilation is different on the 125 and 225 TT TW (XT).
But this did not influence the pressure in the crankcase.
The ventilation of the 125 is sufficient
I placed the clutch housing 225 on the 125 engine, no problem!

Not on mine, mine's closed
I know it will run, but they made an alternate design, to deal with the oil splash when using that 6 disk cover
Early 225cc cases (1983 and 1984 trikes and quads) did NOT have a 225 vent house, they vented the same as the 125/200cc mc cases....they also used the Yamaha15A XT200cc engine balancer instead of the later 1KH 225 balancer.
