In regards to 00 and up,,,what jug would be the best for modification for an 02 CR125? I know a few years back, Yamaha was running 94 250 jugs on their 250 race bikes, same priciple here. I would think that if you went w/ an earlier year cylinder, you would have to get the ignition system too, no? Reason being, I have a new 00 CR125 "B" jug that I can either sell, or use. I think I remember reading somewhere that the 00 jug was best for low end, and that top was easier to get modification wise than low end. What do you guys think,,,,let the bashing begin :aj: :aj: :aj:
