Frustrated, I left the damn thing alone for a few days, then thinking that the restriction may have something to do with the revs,i remembered a video id downloaded off youTube that mentioned a pink wire, and after hours of collaborative research into it, i was under the assumption that as my CDI was 6 pin with 6 wires, one being predominantly white with a pink stripe, and being located at the pin that leads from the CDI to the stator trigger pulse, that temporarily cutting this wire would fool the bike into thinking it is standing still, and allow you to rev the bike as high as you want!, alas guess what happened when i cut it ;) thats right absolutely JACK $H|T, it wouldnt even start, so reattached wire an starts fine as usual.

There are some other exhaust restrictions. are there other black boxes? Oh well, sorry for rambling, hopefully youve got a clue about how my moped is restricted, because being LOCKED down in 50 KPH is very annoying. P.S MOT last week showed no indication of pulley trouble, or anything else for that matter! Whilst this can be done it is usually not worth the effort.

Got to thinkin bout rollers in vario. Alternatively it is also possible to buy unrestricted exhaust manifolds (e.g. Best, Daniel. I noticed that the variator roller weights are pretty . To avoid that the restriction piece falls into the manifold when grinding you should build a hook out of some wire and secure its position. You can try squeezing out a bit more by modifying the stock airfilter. Do you have a 125cc scooter and don't know how to get more performance out of it? All Piaggio engines are the same, therefore if the exhaust doesnt fit, its probably for a different engine Although the Stage6 have shown some horrible quality control in the past with their China goods Anyways, get in touch with the dealer and ask for a replacement.

I was looking here, for info just to get the bike performing to the levels it would in a higher-pressure, warmer climate, with a lack of hills with 10% inclines. The rear pulley acts weirdly and doesnt fully close, hence does not allow the belt to travel all the way up. Derbi has Minarelli engines I believe. CDI The problem with those CDIs is that they are a) not documented, so youd need to reverse engineer the circuit yourself and b) they are usually one big piece of glue underneath the plastic. To modify it, youd need to identify which transistor controls the maximum RPMs, and what components set the frequency at which the transistor stops allowing the oscillator to speed up. Alter the variator system by removing the restricting washer underneath the front pulley wheel.
