Hello, Im trying to Sync my V4 cyl VFR 750 dirt bike (its dirty :laugh: ).
I got the carbs synced ok and then put the intake and airbox back on with the filter and checked again. I had to fine tune the carbs agan but Cyl 3 was WAY high. I adjusted the linkage all the way out and got it better but its still high. Cant think of what would cause it to do that, I changed the cyl over to anoter tube on the vac guage to check it and same reading. I did not touch the PAJ but thats the only thing I can think could be causing it. When the vacume is high, dose that mean that cyl is getting more fuel than the base cyl or less?
The bike runs Way better now that I synced it but Im just worried about that one cyl. I still feel a bit of lug when diriving at constant speed and giving just a bit more throttle, but anything more than a slight crack and it feels great.
