Im going to upgrade my series 2 engine firstly I cant afford a muggelo,rt, imola etc so Im going to put on a 175 kit. I have a jetex and a AF clubman so will be run with these. What I dont no is what is best.
Should I
1. Buy an of the shelve kit?
2. Take a 150 barrel out to 175, If so what piston should I use and what is the best barrel to use as in a gp150 or li etc.

Get a good quality piston..maybe asso or the like and get some decent porting work on it..you know the man. my stage 4 has exceded all my expectations..

Which of the many men would that be?

It has been noted that some 175 kits have small piston - bore clearance. This could lead to seizing, however carefully they are run in. If you go this route it's worth checking before you fit. I know, I've been there

So its prob best to get a 150 barrel bored out and a decent piston as appose to a of the shelf kit

Prob cheaper as you might not get a decent quality piston..

Any idea mate what would be the best 150 barrel to use or would it not make much difference seeing as I will get some porting work done on it

actually ...i would go for and recomend the AF 175 kit...and then get that sorted and ported...as opposed to any bored out 150 /or 175 cc cast cyl...

Is the piston up to the job with the AF kit Sean
