Polini 177

I am planing to put polini 177 on px 150 with electrostart. My plan is to put polini177(14000800), longstroke crankshaft(46000000), carb from px200(400000T7) and simonini racing exhaust(40307000). But I'm not sure about gears and clutch,do i need to change it? Also do I need to modify engine casing to fit the cylinders? What else will be good to change?
Thanks in advance

i think the px200 gears and cluch will be the best choise for you

 

best regards!

if you want the easiest/cheapest way, i'd go with the 22 tooth cosa clutch. it will give you a bit of upgear.(about 2-3 mph.)

the px200 gearing is great.(more upgearing then a 22 clutch with your stock gearing.) but, alot more work and cost.

Hi dude

 

I guess it´s ok to mount a 22 dents reinforced cosa clutch.

Yes the engine modifications are necessary for a polini.

If you dont want to modify take the DR177.

I recommend you also to change bearings and oilseals.
