Hi! You need a kit for the cylinder that include a metal plate for the base (3/4 mm i don't remember) in order to increase the height of the cylinder and a new head beacause you don't want to have a 3 mm space between the piston and the cylinder head, that's it! You also abviously need a larger carburetor, 38 mm will be fine 😉 i've bought the kit from HTM RACING, they have a website, you have to write a email to them in order to get a price for the kit and for the shipping, here you go the mail: info@htmracing.ch I hope this will be helpful and sorry for my bad english.
Oh also change the exhaust, Arrow will be ok, it is also homologed, but if you want real performance i suggest you Scalvini or Fresco in order to braaaaap
Officina C thanks for answering your English is just fine i use autocorrect so my text is readable😂 the thing is im on a budget so first thing im going to do is change the exhaust and so on where are you from btw?
Yes, so if you are on budget i suggest you to follow this order: 1 - exhaust (small improve, linearity) 2 - cylinder kit (big improve, power) 3 - carburetor (final step) The original exhaust has got a sort of catalyzer, and the original cylinder is exactly the same of the WR version but with the holes (i don't know the right word for "travasi" in italian) shifted 3 mm down in order to don't open fully when the piston is at pms (the kit provide this) and eventually the original 28mm carburetor... is a 28mm carburetor 😂
