Hi you have any questions about this listing, please call Charlie on 07719607758

Ok so this was originally a yamaha  tzr 125 2rh/2rk motor.

It has been converted to take the yamaha  thai model 3RR TZR 150 59mm bore top end and the cases have been machined to take the long 54 stroke crank that takes the cc to 147cc with lots of pulling power/ torque and horsepower.

The stator plate has a spacer machined and fitted to allow correct pick up alignment 

The motor doesn't come with clutch or the cover  what you get is what's in the pictures.

There is a small mod needed  to the cylinder head rear support to align it .

I have fitted one of these conversions before and it's not a big mod 

It comes with reed and the 3RR big yam manifold to take bigger 30 mm carb but coukd be set up using the stock 2rk carb and manifold 

There is also optional 34 mm intake that allows use of dellorto vhsb 34 mm carb if you wanted.
