Or maybe on the wheel end but mine was on the clocks. I bought one a few years ago for my nc30 jap import to convert kmh to mph and was quite an expensive bit of kit, cost me around £100 so if that is the case you could probably sell it if you can put it on eBay France or anywhere in Europe.

Years later, £££ spent on tuning, I'm lucky if I can get 70 out of it. Yeah, I put on weight. My RS on the other hand flies!

Also appreciate that a lot of these bikes were ridden by youngsters weighing 60-70kgs.

Here's a link to a German website which explains the different CDI's. http://dtpedia.de/mediawiki/index.php/CDI_Steuerteile
I don't think your problem is a restriction problem, only starting on full throttle from hot? Maybe fuelling or maybe compression? Sounds like your bike is a full power unrestricted french import.

Get yourself an aftermarket CDI and all those problems will go away and it'll fly through the gears.

Looks tidy though!

Also the powervalve is pinned open so after about 6k it sort of comes alive. Is your powervalve working ok?

Welcome to the forum.

That's certainly a long time ago? What DT did you have back then? An mx?
