Thanks, ordered the other type of clips for my Speedengine build.

Hard to say, but it dropped out when I removed the cylinder.
The inlet and the crank are both ok.The “scratch” is 1 mm deep so I had exhaust gas recirculation which explains the poor running

Ouch… I completely missed that it was the plastic part from the carb….. :D, I thought it was a completely different inlet type that was thinner…. (I actually don’t have the engine yet, it’s on its way by mail)

But the alu-part of the inlet doesn’t look to be 13 mm?

Great list, thanks!
I’ve seen many Simonini exhausts called “Racing”, do you have a link to a shop?

THanks!
Will the Gianelli Fire or Leo CC give decent low-end torque?
Has anyone tested Simonini Calibrata?

Dea_944t reageerde in het onderwerp Really bad brakes… in het forum General questions 10 jaar, 11 maanden geleden
I’ve already tightened the cable as much as possible, any more and the wheel won’t be able to run freely.
The brakes has benn getting worse and worse the last couple of weeks and now they are simply dangerous…. I degreased very carefully but I guess my only option is to open the hubs again and check.

Forgot to mention that I don’t have a vario, that’s why I need decent low-end torque and not only high-rpm boost.

Yes, I sanded that braking surfaces lightly and then cleaned them.
The adjusters are set so that the brake shoes make contact almost at once, the problem is just that they don’t give enough friction no matter how hard I press…

Are ferodo available for the front wheel as well?
Just changed to Newfren but I’m not impressed with the braking
Available but hard to find.

Dea_944t reageerde in het onderwerp Liquid metal for orig carters – DR EVO 43 in het forum General questions 11 jaar geleden
Any differences between the port size in the cylinder and the port size in the carter will led to air turbulence and less efficient flow.
When using the DR cylinder the cylinder port will be smaller at the middle of the large transfer ports so the air going up to the cylinder will hit “a wall” and cause turbulence.The best solution is to fill…[Lees meer]

Dea_944t reageerde in het onderwerp Crank timings, original and modified? in het forum Opvoeren 11 jaar, 1 maand geleden
Agreed but since it’s the combination of crank timing and inlet opening that gives the complete timing it would be very interesting to get measurements on other original and tuning cranks.
Where can I find the timing calculator?

EDIT:
Just disregard the part below, I confused the moped/brom cranks and the mofa/snor cranks….

I will measure the cranks and put up some pics on how I plan to modify them, if it doesn’t work I will try to get hold of a a moped crank (unfortunately almost impossible in Sweden as only the mofa version was sold here) or get a good quality…[Lees meer] -

I couldn’t decide so I’m building two engines 😀
One with the Speed engine carter and the 46 mm Polini and one with a “belgian” carter and the DR Evo 43 mm.I opened the engines I had and the only moped crank was an old one without needle bearing…..
Looking at the difference it should be possible to change a mofa crank into something that…[Lees meer] -

Thanks for the comments! this really is a great forum.
I’m building two new engines:
1) Polini Speed engine + modified “brom” crank + Polini 46mm + Dellorto 13/13 + Polini airbox
2) Belgian carter + modified “brom” crank + DR Evo 43mm + Dellorto 12/12 + Polini airbox
Low end torque and “original looks” is most important, not top speed…[Lees meer]

This engine will get a DR Evo 43mm and a 12/12 Dellorto so it seems to fit perfectly.

Interesting, the “brom” carter version was never sold in Sweden.
I think the inlet is 12 mm.

Interesting, I didn’t even know that there were different versions of the crankshaft… I have a couple of original crankshaft in my garage, let’s hope at least one of them is for moped…
I thought that low-end torque increased if the opening intake timing was increased slightly?
I want torque 🙂 no variator and a lot of hills where I…[Lees meer]

Removed the springs and now it works 😀
From time to time I still have to run a few meters before the start shoes engage.
All washers are in place and the clutchhousing has been degreased and the surface roughed up a bit.
Still not sure why they started sticking but I will file the inner sides of the start shoes and use some high-temp grease to…[Lees meer] - Meer laden
