bosch 4214 is the one I found. I really based my test on wich one gave me the biggest spark outside the engine, and which one gave the best acceleration.
The bi-turbo is working great. I finally got a UNI foam air filter, and took it out for a nice long ride. It's better, but still a slug on take-off. The top end is soooo much faster. I still need to order a speedo. cable from handy bikes, but that can wait- I'm going on vacation for a week, starting Thursday.
35? Man I bet that feels a lot better than 25. You still using that proma pipe from the honda?
