my t5 isnt as fast as it used to be, replaced the rings early last year which helped a fair bit for a while, have had a go on mates t5's and they just seem that bit quicker pulling my 17st arse, im looking at going down the 172 or 152 route, i mainly use me scooter for drashing round town but do the odd rally hundreds of miles away so want reliabilty i preferably go for something bolt on , at the moment the only engine mods are a right hand sterling exhaust. i like the 172 because of the small running in miles and the facts it a nicosil lined however the price is a bit steep specially without the cost of the head included, what are the 152 kits like and would i be able to run one with the standard head? im more than happy with my t5 topspeed once she gets going but any sort of hill or headwind kills my chances of getting there.
cheers for any help/advice in advance :)

another option would be to get a knackered 152 polini barrel (plenty around) and get a Suzuki conversion on it, chiselspeed will do this for you, and your cylinder head machined to match. pistons are cheaper than malossi if it goes bang. Polini 152"s are good kits, but you need your head done to suit, and they are very tight fom new, and need a good hone out and the port edges chamfering, but when done pull really well. I run a malossi, but me mate swears by his polini.

Is the Sterling pipe the issue? Too peaky for your...er...bulk... perhaps? :oops:
You said you mates T5's go better than yours. What exhausts to they use?
If your cylinder plating is sound then a new piston and a better exhaust may get you where you want to be without any semi-serious engineering.

I wasn't meaning to be rude as I'm hardly twiggy myself as my hard of hearing mother-in-law likes to point out. One time a new TV game show was advertising for contestants on the Radio. She told me it sounded perfect for me. "allmost certain to win it our Spanish lad". So she put my name forward. When the paper work came through it turned out the name of the show was Fact Hunt! Bitch.
