Here ya go:
Rex 12v conversion

Will it work for a 250

do you have strong ankles.you will need um with rexs kick back..

What is the British L conversion? how much to ship & how long to get it? The # looks to be a foreign country? Or am I wrong?

I'll look into that but when you find a good one tell me

So I've heard, I did also hear that it was taken care of when timed right but I thought it was a bolt on system. I wish someone with the Vape kit would chime in, that's why I originally made this post. The Vape kit is more but if it works better and is a true plug and play kit then it's worth it.

Rex's system is Plug n Play, and since I de-coked the decompression hole in the cylinder, kick back minimal, but again I've nothing to compare with and as I never ran the bike with the 6v system I don't know how poor it was, can only speak from my experience and I think £260 is a pretty good price, but as Ive only covered a few hundred miles since my rebuild Im still in the learning phase. Hope you get sorted which ever one you choose.

Thanks for the information, I am leaning towards the Rex kit at this time so we'll see. Thanks again!

Hi AirborneSilva, You might want to hold off on the Rex for now, as Ive got the same problem again with mine literally 2 weeks after getting it back, ill ring after the bank holiday and update

Thank you, I'll hold off and I appreciate your feedback! Good luck in getting it sorted out.
