I've tried a quite a few but Silkolene Pro 4 is my preferred choice.

Never actually compared the two but I think the Seeley hubs/backplates were sourced from the CR125M.

Sorry, it's the other way round. Early production bikes had white Preston Petty 'mudders'. Later bikes had black VFs. We've had both variants from new. The change to black VFs was made before frame #1118. Neither had integral front mudflap. Still got both bikes - white looks best!

Try this . Don't use any throttle till it fires. Even when it's hot, if it won't start use the choke and no throttle, just knock the choke off as soon as it fires. Had the same problem with one of the kid's 125 pro racing. I did the float level and iridium plug etc to no avail but this routine sorted it out .

I had a similar problem with mine, drove me mad. Turned out to be the fuel. It has to have fresh petrol, if it's more than 2 weeks old the bike won't rev. Before you do anything else drain your carb and tank, put in the highest octane fuel you can get with a good 2 stroke oil and see if that sorts it.
