May sound silly but I was wondering if anyone has tried using a more modern tuner on their F4i such as a PCV for instance? I'm run a shop based out of Wilmington, NC and we are building a track bike to play on right now. Running Wiseco +2 pistons with Carrillo rods, cbr zone cams and kibblewhite supporting valvetrain. 600rr swinger with an Elka 1000rr rear shock and 1000rr front end. I just wanted to give everyone a little taste of what the bike is like. I'll post some pics once I get them uploaded at the shop. I have looked into MegaSquirt for a tuning option and it can be done. It's a lot of work though so I was wondering if anyone here has tried any other tuner. Thanks for any input.

 

can you even connect a PCV to an f4i...?

 

The plugs look close but I'm not sure if there's actually any benefit by using the PC-V. I have port work on the intake and the throttle bodies are ported as well. I ported the tb's by hand and then capped one end off and did a fluid cc test to be sure they were all exactly the same.

 

I seem to remember someone having used a bazzaz on an F4i but don't remember specifics.
