So there's two kits I'm looking at as simplish upgrade on to a 43mm stroke pk75xl motovespa. Scoot has the tougher 20mm crank , 20mm shbl carb and the more robust xl clutch.

Theres an iron 5 port 102 pinasco or the aluminum nicasil lined 6 port 102. Scooter centre claim the aluminum kit more reliable for longer journeys and full throttle runs due to heat reduction. Theres a 35 quid difference in price . Anybody had any experience of these kits on small frames? Is running i time less on the nicasil lined one? Thx

35 bucks is cheap insurance for better heat handling the way I do math.

Never had the chance to A/B and iron vs alum pinasco. I do love the 177 aluminum, on my VNB. (And, I stayed at a Holiday Inn Epress last night!)

Thanks for that input. I note the pinasco has a 26mm outlet which is same as my new bgm pipe so didn't want to lose this exhaust as it performs well on the 75 and since fitting it I have no vibration issues with panels, headset and toolbox. The bgm will bridge 52 to 56mm exhaust stud gap so can still be used. Just got to find a pinasco dealer in the uk now as not easy to find.,if anybody knows of one can they let me know. I think a 3.00 ratio primary would be right for this kit but as the xl75 is an oddity need to check what's in it already .

like birbs I'd go for the alum for peace of mind, especially at that price difference.

the only down side is that you can't rebore and go next over if you lunch it real hard. so, like, jet it fat my dude.

my advice is worth exactly what you paid for it and no, I did not stay at a holiday inn last night.

The scoot is currently waiting the arrival of parts from SIP, tomorrow in fact.
Ive ordered all of this. I have the 20mm carb, uprated clutch and BGM box pipe already. Should be a good little runner and take my miserable 5hp to god knows what. The scoots on the ramp and hopefully be on the road couple of weeks.

Ferris,

are you sure that crank works with those bearings? The bearings look to be standard casings with ETS crank. I thought your engine was ETS style cases, and that looks to be a standard 20mm bearing crank rather than a 25mm ETS crank. The same with the seals.

I got it wrong, the engine is 20 crank. It's 96m engine. Weird 125 stud rods but uses a 43 crank with 75 cc barrel . That's why we couldn't fit a 102 kit as it uses bolts not studs. I got sent a 102 kit which I had cancelled on realisation but they refunded cost and not asked for kit back. Brand new dr102 kit available cheap to anybody wants it. As a 75cc it would hit 50mph gps which is crazy for tiny capacity standard. It even has the ets 20mm carb and inlet . It's all confirmed correct by mechanic , the stator and flywheel kit we bought in the year is for 20mm crank cone so clearly not an ets crank . The parts were also matched on a configurator for the 75xl which is nion impossible to find info for. A very strange engine setup to meet Spanish legal age driving requirements.

Are you getting the standard flyside bearing and seal to go with the crank?

And yes, it is a very strange engine. With the 102 kit, you can remove the long studs and replace with the short type for the smaller kits. I've only ever done it the other way round but the stud spacing is the same.

Crank is probably wrong, it should be the 20/20 version. Are you sure you have a 19mm cone flywheel?? Kit is a bit meh, 1400050R is better, with a better head and studs. Bearings may also be wrong. Have you split the engine to make sure what you got inside??

Kit is the following and only 7€ more expensive than the "Mono" version...
