Re: PX 125 Gearing

The T5 fourth is the same as a px125 one I think. Using a clutch with more teeth is the easiest way to upgear your engine. I think a px125 has a 20 tooth clutch. A 21 tooth will give a 5% upgear. A 22 tooth clutch will fit but your scooter might not be powerful enough with only a pm exhaust and no o...

Re: Squish too large?

I agree with Holty. 1.2 would be a good target. I always thought that a large squish would give a cooler running engine but that wasn't the case with my bro's polini. We were shocked at how much cooler a lower squish runs.

Re: Vespa wobble

Small wheels and quick steering geometry make scooters very agile in town but on the open road handling gets interesting to say the least! Even after years of scooter riding it still takes me time to adjust after riding a motorcycle. I hope you stick with it!

Re: Vespa wobble

I've never ridden a 946 but things to check; Tyre bulge or damage. Buckled front wheel. Buckled back wheel. Forks too tight with either overtightened bearings or slightly bent and not turning side to side easily. Worn bearings causing play in the wheel on the front or back. Under inflated tyres. May...

Re: Importance of Leak Testing

I'd never build without a leakdown test now. Maybe it's the most important thing I've learnt in the last 5 years.

Re: Mag flange all the same?

Mine was the same. Being paranoid about overheating an expensive engine I tapped the headcowling over to fill the gaps as much as possible. Not pretty but it put my mind at ease!

Re: CHT Meter

Mine is on a gt240 below the cylinder head nut furthest from the fan. The wire comes out of the spark plug hole in the cowling. For me the temp is a relative thing. Uphill against a wind in fourth at low revs I can see 170 plus degrees, in normal speedy riding it can be anything from 135 to 165. Whe...
