QUATTRINI M1XL

[MattsDad]

You don't get 24 out of the box I'm afraid, probably 16ish"

Well that's what those Germans @ SIP are claiming!

Spoke to Chiselspeed yesterday about the build - and they' were real helpful, seem to know quite a bit about this kit & suitable spec's, set-up's, ect - so seems like they'll be the best option for the build.

Cheers All...

Ha ha, small world.
I was there when you rang, so it was you!

Well... picked up me freshly built M1XL motor yesterday afternoon.....






.... I Decided to go with Scooterotica Garage in Ripon for the build.... Dan only recently built a Polini 221 for me & I was very impressed with their service & set-up - I wouldn't hesitate to recommend them to anyone, and I don't think I would now go anywhere else...

Sean Brady did the build on the Quattrini & has done a first class job, with a very fast turn around (only two & a half weeks from drop-off to collection)....

Build Spec is;

• PX125e Donor Engine - Casings welded to accommodate re-porting of transfers to match kit - electric starter removed & hole blanked-off
• Quattrini M1XL Cylinder Kit - Inlet Manifold re-angled to prevent carb fouling on engine - and ported/flowed internally
• Mazzucchelli 57mm Full circle Crank
• Dellorto PHBH 30mm Carburettor - jetted to suit kit/pipe (ballpark till I get it dyno'd)
• Tassanari VForce 3 Reed Valve Kit - substituted the reed block supplied with Quattrini kit for a VForce 3 item
• Vespatrionic Ignition Kit
• DRT 65t Primary Gear
• SIP Cosa 2 ‘Sport’ 22t Clutch
• SIP ‘JL Curly’ S/S Expansion Exhaust
• All Bearings/Seals/Gaskets Replaced

Great looking engine, what frame is it going in & would you mind showing the exhaust side.

It's going into another Motovespa 150s frame that I have - which is away getting painted at the minute, so hoping to get it back in the next week or so...

Could be a little while yet before I get it fired up & running in this frame though - and it won't fit into any of my other frames with that curly pipe on...

Do you have to modify, the battery side panel for the pipe to fit. I know if I was going down that road I would need to cut the bottom of the GS150 panel, but that doesn't bother me as they are remade panels. I was more concerned with the height of the pipe. They are fcking expensive exhausts, so don't really want to waste the money and it doesn't fit. Im a sucker for things that are over engineered, I would like to fit a rear disc brake for that reason, but feedback on them put me of. Are you fitting a front disc brake?

[cartmel808]

No modifications were needed to the side panel for the pipe to fit - the panels on the Spanish 150s are very similar to (if not the same as) a GS160 - so more room under there than most other models I would have thought.

I've had to to cut-off the the battery tray/spare wheel carrier from that side though, in order to accommodate the pipe - but this isn't really an issue for me, as it's a non-battery model anyway - plus I'm fitting SIP tubeless rims, and will only be using it for short runs & hooning around on - so not to bothered about lack of a spare.... (famous last words!)

I was originally planning on putting this motor it into my Sprint Veloce frame - but this has a sealed left hand panel with glove box (similar to your GS150), so I would've had to butcher the panel to accommodate - or go with a different pipe.
Once I get it bolted into the frame, I'll measure where the top of the pipe comes to on the side of my frame & PM you the measurements - that way you can see if it's a viable option with the GS side panel.

I am planning on fitting a hydraulic front disc brake set-up - I bought a Harry Barlow fork conversion off eBay last year, so gonna use that - but need to research which disc brake kit will be best to go with..

Really appreciate the positive feedback.

Glad you are pleased, it always makes a job worth doing when you get feedback like that.

Thanks

Looks good just a couple of questions have you sorted an air filter for it? And secondly what are you doing to overcome the inherent cooling issues caused by poor air circulation?

[cartmel808]

I've not got as far as looking at air filter options yet - & TBH, I'm still undecided as to whether I'll fit one at all...

And as for any cooling issues - I'm still a way-off getting the motor into the frame & up 'n' running, 'cos the frame it's destined for is still at the painters - and then it'll all be to build-up - so this motor's just art for me garage at the minute ..... but - what are the 'inherent cooling issues' associated with this kit - no-one's ever mentioned this before?? ....

if I were you , I"d fit either a foam filter, or some kind of bellows to the carb, the proximity of big carbs on large frame vespas puts them right in the firing line for any s**t hoyed up by the back wheel. frame to carb bellows on mine, but as yours faces rearwards, a foam , or even a fine gauze would be my choice. a lot of money to go up the shitter by a stone or piece of shite getting whacked in by the back wheel.
