I bought one for my road bike to try and get a little extra power out of it after doing the head mod again. Incredibly impressed.
When I tried the RM125 CDI on my bike I knew there was a hell of a lot to be gained by a bit more ignition advance. And after 6 maps tested out on the road on the SM, its starting to feel perfect with about 4 degrees earlier on, and 2 degrees later on, advance only. (which is surprising as most of us would believe a bit more retard at high rpm would help, but I suppose the porting and exhaust suggest otherwise!).
Anyway, the unit cost me 154GBP. And the second time you buy you get a nice discount, and if you order more you get a sizeable discount!
Even better, I ordered 1 day, and it came the next from the Czech Republic!
http://www.ignitech.cz/en/ is the website, the AC unit isn't listed anywhere but the price list. I will make another order on Monday. If anyone is interested let me know and I should be able to get at least a little bit of discount!
