Gillera st125

hi bought a new st125 back in 2010 still in showroom condition and still only done 2k. used to own a sp 180 that would do 100+ mph.so now im wanting to tune the st125 but unsure witch parts to go for as ive always messed around with 2T.any help would be appreciated

thanks in advance

are they both 2T?

 

no st125 4T

 

I would of said would the 180 engine fit in the st.

but I thought that might prove difficult putting a 2|T engine where a 4T engine is

 

suppose it could be possible

 

Your 180 sp must have been very special as there's not many Runners that would do 100+mph, was it a 38hp £2000+ PSN engined Runner!
