I'm not so sure now! Put mine in on my Raptor and now have an intermittant "bog" or miss that will sometimes even kill the engine. It strikes me as being ignition related. Everything was installed exactly per instructions. This happens randomly and follows no pattern, although it seems to happen after the engine is fully warmed up. I don't think this engine likes the timing advanced 6 deg. It kind of ruined the dune trip that I just returned from. What observations have you guys made who have done this modification? Any problems? Is the performance better? I'm really bummed out, because I can't pinpoint the source of this problem, and I'm not wild about pulling the sidecase and stator rotor off again. Any help and/or suggestions would be appreciated! Anyone else with these symptoms?

 

They say they are suposta be good but I have always thought at a certain point since it is advanced 6% and all that sometime along the line it will get "thrown off" the current if that makes any sense?? or send the spark too far in advance and misfire? something along those lines, if that made ANY sense at all??! lol!
I just think its a bad idea...

 

I must have mine installed wrong because I have had no problems with it at all except that it starts differently now. A little slower. I like the acceleration now. Putting it on is easy except for the oil mess.
