Tuning / porting for 55mm stroke

Has anyone got any recommendations who to use to get my new 172kit tuned / ported for 55mm stroke ? I done the long stroke myself on my vespa. but for the italjet I would like some one who has more experience to do it for my dragster.
I know pm tuning do it still

 

Whereabouts are you? I know a good place in Peterborough ..

 

I'm from Kent 20 miles from London

 

Not sure then bud, not very familiar with Kent

 

I'm from Peterborough originally. I'm wondering if it's the place my buddy Kyle works

 

I don't know about that mate but they used to be called Taz motorcycles and they're now called Wheels, and when I had Italian bikes I would go there from Cambridge and the servicing was great but not particularly cheap. Now I'm older I do my own servicing anyway. I would still recommend them though.

 

Yeah not the place my mate works at, is bikes trikes and stuff still next door to wheels?

 

Not sure, it's been a long time since i went there. A14 roadworks makes it too much hassle!
