small block engine upgrade options ?

thanks mawso I guessed the kit used Suzuki parts somewhere but wasn't sure how.

I bought a 200cc cylinder kit a couple of days ago . When I get around to fitting it I'll probably do a stage ll tune on it myself . i don't think I would want to spend £200+ on a cylinder kit and then have to pay loads for stage 4 tuning and other machining etc I'd just buy a Mugello and whack it straight on.
