Re: Is there a reason why this happened and can i prevent it
Maybe the plug cap is a wear part in the same way as a cruciform is. The cap does alot of heating up and cooling down and maybe hitting potholes along with the heat takes it's toll. Have had a loose exhaust bolt once. It cut a nice tread in the tyre!

Re: best exhaust for px125

Re: Malossi Polini swap?
Sounds perfect. I'm shocked it runs ok with only a 125 main jet. It wasn't enough in my brother's polini iron barrel/grand sport/jl but it just goes to show that not every scooter runs well on the same set up, each individual case is different. Enjoy the miles!

Re: Vespa PX200 Top Speed
My brother bought his px200 new in 2003 . After the cushdrive failed we realised his scooter was fitted with a 125 primary . Is there a chance yours is the same ? We were always shocked reading about p200's struggling with 4th gear when his would rev out easily but only doing 60ish mph !

Re: more cool air
Sounds a good idea to me . I'd never have thought of it . I doubt there'd be a huge difference in any intake method but I'm definately interested in the result . Another benefit might be some extra storage under the seat for wetgear or whatever after a small bit of cutting . It would be a great spot...

Re: HELP needed, t5 engine bogging
Have you a standard pipe you could try ? I've never tried a sterling exhaust but have tried a few others......in my experience standard T5's never work great with performance pipes . They just make an already narrow powerband even narrower ! Soulboy is on the mark with the airscrew but you could exp...

Re: 172 transfers
Thanks ducksta for the quick reply . In fairness , I think the T5 must be the only engine where the transfers in the casing are larger than those on a malossi barrel . They aren't much bigger but there's a difference all the same . I think it must be a cooling thing where the fresh charge splashes t...

Re: catastrophic....
I had the same thing happen to my 172 on the way back from the Norway vespa world day . I decoked my scooter 3 weeks before going on the journey and changed the rings too just to be on the safe side . It ran perfect on the outward journey but returning on the M25 I had meltdown . Luckily I was trave...

172 transfers
I've a spare T5 engine on the workbench and a malossi 172 kit ready to fit . I'm wondering has anyone matched the barrel transfers to the casing ? Does it give any noticeable power increase and nearly more importantly , would such work silence the malossi rattle ? The other thing I'm tempted to do i...
