Puch polini stuff

Hello guys!

I’m building a polini kitted e50 for my maxi project. The motor has a rito crank, bushing type lightened bell, treatmetric clutch, and treats cdi. I case matched it but didn’t go too crazy since I’m not extremely experienced with porting. I will be running a genuine 15mm bing with the intake and reed valve that the kit comes with. I realize that I could go with a better block, intake and carb, but I do not plan on making this bike rip too hard because I can’t afford to replace all of this stuff.

I have a few questions about tuning and stuff

What’s a good pipe for this bike?

I was going to use the technigas or Estoril sidebleed but they’re all out of stock

What’s good jetting with a similar mid/low end pipe?

What clutch springs should I use?

Any tips on setting the timing for cdi?

Does the piston ring come gapped correctly? I understand I should have it gapped at about .174mm?

Any other tips?

Thanks!

Jacob

Timing depends on temperature, start low around 14° before top dead center with a timing light you could always add more timing if you run cool at full throttle runs,

Around 90-86 main jet, 217 atomizer/needle jet with a clip rich on the needle maybe full rich needle, a derestricted estroil pipe is best for it runs cooler and is quiet, super stiff springs 2 or so turns in from from flush if stock clutch, Ring Gap may never be right on kits so measure

Thank you for all of the info!

I will remember that went setting the timing and will be certain to check the gap. I have the treatmetric jammer clutch. What colored springs would be best for that particular clutch? The stiff ones still?

I cannot find any Estoril pipes since they are all sold out.

This was the pipe I was considering? Would this perform similar to an Estoril sidebleed

Can’t stand the jammer clutch because shoes are not asbestos lined which means you can’t use synthetic motor oil you have to use junk tranny fluid, can’t stand the side bleed peoples pipe either as well as junk India made CDI, so you’re on your own sorry,

Wonderful stock six wire point ignition, estroil pipe, stock 2 shoe clutch with thick springs:

The video is over five years old but My set up was built 13 seasons ago and still runs perfecto with maintenance to ring piston and ignition.

You’ll be lucky to get one season out of what you’re trying to do and there’s no way you’re going to get the 58+mph I do with great take off for the years I do.

The weak links are the India CDI, aftermarket clutch which goes sparkless at the worst times that has Kevlar lined shoes not asbestos, a pipe that’s not a derestricted estroil plus you have no clue on gearing and whatever else you did wrong by buying aftermarket crap when stock euro stuff is superior,

Right now is the 13th season of this wonderful maroon maxiluxe and it blasts almost all step/most any mopeds and many small motorcycles and scooters, including Honda mb5, elite 50-80cc, Yamaha 60-80cc all of them are all in my rearview mirror,

Today I even blew by Toyota Prius like it was standing still at 55-57mph,

Sweet reliable set up, 1980 maxiluxe built in late 1979, oh ya still has the stock brass bushing non needle crank too. I’ve had several bikers/Harley Davison owners ride this bike and they Couldn’t believe it was a moped,

It put a smile on my face today like it did years ago :)

I hope you live with a few miles of where you ride because you’ll never be able to ride all day every day and make it home with all the crap you’re using on your build,

Re: Puch polini stuff

This reminds me, I need to get off my ass and build my Polini Free Spirit. Time to put together a parts list.

Re: Puch polini stuff

I bought one of those MLM peoples sidebleed and it works best hanging on the wall... It de-tuned my polini w/19 dell and Dio reeds... I run 3 polini e50's w/same set-up 2 of them have the sidebleed Estoril and one with de-re-Estoril pipes... The MLM peoples pipes have small chambers and are built thick and might work good on milder cylinders....

Thanks for the input. The only issue is that all of those Estoril pipes are out of stock. Are there any good alternatives?

Re: Puch polini stuff

Post for used in Buy & sell, Treats have been out for such a long time... I sure hope they get more in...

Re: Puch polini stuff

Just found out Denny cycles has them. Just snagged one! They were out everywhere else.

Puch black pipe/chrome pipe/raw pipe performs very similarly to estoril, a little better all around. I imagine it would do well paired with a polini.

Re: Puch polini stuff

i would definitely skip the treats cdi on that setup, the only time its worth going to CDI is if you need the auto-retard feature to keep things cool.

stock points will be just fine, one less thing to fight with for your first build.

Re: Puch polini stuff

Jacob Becker /

I thought the auto retard would be important on this particular kit. I already bought the cdi anyways, but do have a points setup I could go back to. Thanks!

Re: Puch polini stuff

Naw, you only need it on stuff with big pipes, big carbs. You know you will need a jog box or something like that too get it to retard, right? The box that comes with the treats cdi is fixed timing

Re: Puch polini stuff

honestly, i have to second or third not using those treats cdis. I chased issues with them on my polini setup for months until i swapped it out.

also, one of the fastest polinis i ever saw used points, so ymmv

and even though roffman comes across as a dick, i also kind of agree on the two shoe. (edited)

Re: Puch polini stuff

Jacob Becker /

Fair enough. I didn’t mention that I was going to be using the pietcard cdi box with it which would probably be making a big difference.

I have a 80 euro kit on an e50 with treats cdi with that pietcard box and a hammer clutch and haven’t had issues.
