hi,i have a 2013 px 150,it s a stock motorcycle till now and i was reading a lot on this forum about the best tuning parts so i would appreciate your help on my plans for tuning my motorcycle....

1.i would start with the cylinder kit,i know a lot people would suggest a malossi or polini kit but i was thinking about the parmakit 177 mostly because its made of alloy and i think the price tells it all compared to the polini or malossi

2.im not so sure about the exhaust but by reading alot of people are suggesting an exhaust with an expansion chamber so i was thinking about

3.i was planning on buying a long stroke mazzucchelli crankshaft (60mm)

4.to put a bigger carburettor ,maybe the
Dellorto VHST26BS Racing Red Carburettor

5.ignition:Parmakit Electronic Ignition System 1kg Flywheel

6.clutch: a cosa clutch ,i heard they are the best

7.gear ratio,transmission:???????




I would really like to hear your opinion on my plans and i am open to any suggestions
