got a T5 std 125 but it needs a but more pep.

will a lml 5 port 150 fit?

No, the T5 is a 5 port motor anyway. The only 2 kits that are really available are the Polini 152 and the Malossi 172. The Malossi is Nikasil lined, whereas the Polini isn't. A T5 shouldn't need any more pep, they're as quick as PX200's when they're standard. What sort of top end speed do you get out of it?

mine does 62 on the clock at best flat out in best conditions.
looking for 65ish in all but the worst conditions.

It should do a little more than that. What condition is the motor in? Have you seized it up at any point, and what exhaust are you running?

not been siezed, got a sito plus.
its needs a clutch side seal so is going to be rebuilt.was looking for a little more performance for not much more cash
what are the options for rebore and nicasil and a different piston.

go for that 152 Polini, maybe T5 exhaust and the correct jets and you'll like it!

put the motor right with new seals etc. replace piston rings (they need replacing quite often on a T5) and fit a PIAGGIO original exhaust. mate of mine has just replaced his sito plus with a proper standard silencer (it was £100 quid !) and it has made it run great.

Yer rings are proberbly worn
