Porting a Morini

Has anyone here had any experiance porting a morini mo1 case induced engine if so con you help me out with tips or pointers really any info about this process would be fantastic. Where will I get best gains what can I do how far to go ect.

Re: Porting a Morini

good luck, I have the same engine and not many people know about it. Look at my post called "need help finding a rare kit" Let me know if you find any info out, I want to port mine as well.

Get good at this Rick. Mark is probably getting another morini engined ped this weekend. There'll be as many morinis as puchs around here soon. haha

Re: Porting a Morini

I haven't ported an M1 yet, I'm still working on the M01 now. So far I've polished the crankcase and matched the case halves to their respective transfer ports, you'll need a dremel tool and various bits, I finish off the case with a small hand file and 300grit sandpaper it doesn't get a mirror shine but good enough. I have some port window statistics if you'd like those?

Porting a Morini

When you start porting a top end that not many people have ventured into, START SMALL. Tuning of 2 strokes is tedious as balls. But, if you start by dremeling away at the intake, and only the intake and you find that you go faster/have better throttle response/acceleration/whatever, you then move to the exhaust. You do a little bit, then move to the transfers...etc.

When you do the full cylinder, if you want to go a little further, you go a little further. and continue the circle. Just keep removing material.

Also, have fun, and remember that if you really really fuck your cylinder up, Handy Bikes will have another one.

Re: Porting a Morini

I know what you mean, the M01 espcially has very little material to remove before the case is matched...very shitty transfers IMO. I thought about shaving down the cylinder head a bit to drive the CR from 1:8 to 1:10. How did you access your transfer ports to widen them? There just isn't enough space to work a hand file and I don't use a rotary tool on the cylinder only the cases.

Re: Porting a Morini

Dremel is your best friend...take it slow, and have a light hand...DREMEL <----seriously.

Re: Porting a Morini

There is a top end for that ...metra makes under a different name I think I have one...its new and you can try it before you pay me... it only works for case induction...email your #

Re: Porting a Morini

I won't be ready to accept your offer until my exams are over and snow is off the ground, probably in the next 3 or 4 weeks but thanks I'll make sure to ask again.

Re: Porting a Morini

Shaw,

You have that mysterious new metra that works on the M1 case inducted engines..... may want one of these in the future for my girls bike!

How much they run?

Re: Porting a Morini

Yeah please share that metra info here where we all can see and benefit from your knowlage . ps I'm smoothing out a cylinder now but I have no ideal where to get a bigger better intake for this damn mo1

Re: Porting a Morini

I got one a while ago on ebay. It's not that big though (12mm) but it's better than the stock 10mm. I tried looking recently for one but found nothing. Sorry.

Re: Porting a Morini

I was under the impression that the case inducted Morinis are M1's ??

Re: Porting a Morini

They are. M1 is case-reed, M01 is single speed piston port, M02 is two speed piston port.

Re: Porting a Morini

well I have both of them and they both could use some work

Re: Porting a Morini

Shaw tell me more about that metra kit or call me 314 258 6994 anytime

Re: Porting a Morini

Shaw were you just joking about the metra or what ? Anyways I put my m1 "freshly ported"exhaust port back togather today and saw big gains. Hitting 30 plus on the flats woowooo I did a good thing.Next I need to fit a pipe on that thang.

Click on Downloads. In the general catalog on page 36 is a kit that will supposedly work on a Morini M1.

Worth a shot.

Re: Porting a Morini

oh wow interesting...good find chris.

Re: Porting a Morini

YEAH looks correct to me but that site is goofy

Re: Porting a Morini

did you record the specs of the port job? what exactly did you change and to what extent?

Re: Porting a Morini

or here rather but no records because Im gunna keep going

Re: Porting a Morini

BASICLY I lowered the exhaust port to the crown op the piston and widened it up a little. Its a little scarry grinding into the cylnder wall but it is making a big difference so I wil do more to it soom maybe a little to the intake side of things will help out some

Re: Porting a Morini

so you just ground it down till it was an even circle? I wonder if I should do that to my kit....

Re: Porting a Morini

think like the germans meaning they put scooter kits on puchs all the time. have to know some kool ass friends that owns scooter shops and has shit laying around plus hmm maybe have something mills like make a plate to fit block to cylinder. Spend the money. Its worth it. Ed:)

Re: Porting a Morini

You should read about porting mapping look at how squre everything is meaning the ports. Ed

Re: Porting a Morini

NOOO ITS NOT ROUND

NO i DIDNT CHANGE THE SHAPE AT ALL

I ONLY MADE IT LARGER EXACT SAME SHAPE AS STOCK ONE

LOOK AGAIN , MAYBE I'LL POST A BETTER PIC

SPEND THE MONEY ? ON WHAT MILLS? WHAT DUDE?

I DONT UNDERSTAND WHY YOUR DISSEN MY SHIT
