I was under the impression that no modifications were needed on the Speed Engine crankcase?
Thanks, I had some hopes it might be better as it performed as well as the Leovinci SP.
I asssume that the Proma City Power is about the same as well?
So, did anyone test the new carter-version?
Do you have a picture of it?
Point taken… I’ll try to find an original one in good shape or a Nuovo Mazuchelli
~40 Euros, still pretty cheap
Had a Top Racing in an engine two years ago and it broke so I’m a bit hesitant….
Haven’t been able to find any original moped cranks in good shape, but maybe I should go for a Nuovo Mazuchelli instead
Strange, I run the old-timer coils with the 991790 flywheel to the right in the bottom picture and it works fine?
The 990955 flywheel to the left does not work with the old-timer coil or the “green” coils in the bottom picture due to the larger outer wall thickness, it has to use the smaller coils in the bottom picture.
I probably have an old-timer flywhell as well.
Update
Changed to the correct coils for the flywheel I have and now both the tube lamp, 5W/12V, and the tail lamp, 4W/12V, works fine 🙂
Still don’t understand why the head lamp that is 15W/6V survives and actually is’t that bright….Update
The tail light lamp broke again… The problem could be that I’m using an old-timer coil with a newer flywheel giving too high voltage.The pilot light is the small tube light in the headlight.
Changed the tail lamp and tube lamp to 12V variants, 4W/12V for the tail lamp and 5W/12V for the tube lamp.
The head lamp is still 15W/6V (for some reason the P26s head lamp seems to be more voltage tolerant than the other two lamps)When running head lamp + tail lamp the load is 19W and the voltage seems to be at a reasonable level giving OK light performance.
A 10W head lamp would probably be even better but I can’t find any P26s with 10W/6V.When running tube lamp + tail lamp the load is only 9W and the voltage is still too high so the lamps will most likely not last long.
Not a big issue since I never run it in that mode.Ok, but I guess I can keep the headlight bulb 6V (the P26s) as that one does not break?
They are all 6V
I changed the clutch disc (to another used one, should probably get a new one) which solved 95% of the problem.
Still have more transmission sounds than I want but it hasn’t changed since the change, ~500 kmOn the coils they fit with the thin walled flywheel, 21 mm wall width.
How many flywheel variants are there?In this case it’s a metal rod that I unfortunately lost when moving to my new garage….
Has anyone got a picture of how it looks without pedal brake?
Thanks!
I used 3% during break-in the first 500 km but did have a feeling it was unnecessary to continue with.Main point for running Alkylate is there is less carbon build-up and soot in the engine, also more or less zero smell…
Did you find any solution to the problem?
Removed the flywheel but there were no obvious issues.
I did however find some suspiciuos things:
The flywheel contact area with the cranskaft is not optimal. As can be seen on the picture below the flywheel seems to “vibrate” or “move” causing markings.
The clutchdisc also seems to move and has caused a mark in the crankshaft:
The clutchdisc has marks on the rear side from the bearing, I compared with some other clutchdiscs I have and none had these types of marks.
