Hello again, you may remember me with the fuel problem....
To continue the quest for a better performing bike, I need to know what others have experienced with their vacuum guage.
Mine will wildly swing at idle but will smooth out as throttle is increased.
I syncronized the carbs today and they will sync at 4000 rpm but at idle the rear cylinder has a lot higher vacuum than the front.
I am using Marty's yard stick manometer
any sugestions? I know from a vacuum check on my car, that the needle should be steady at idle, otherwise you have a vacuum leak or the carbs are too rich or too lean. Which is it for these bikes? Do I need to enrichen the jets? (Oh yeah, I forgot to tell you I only have one vacuum line from the front carb, all the others are gone, and I replaced that hose so probably not a leak.....will the idle adjust effect the sync?
The bike seems to run ..OK, not super, but ok. Maybe I am too pickey and expect this 2 cylinder to run like my '71 honda 750 4cyl.
Thanks for any assistance you can provide.
I will be ear shaving in the very near future and need access to a set of jets and shims, I have tried the links in the verses, but none acctually tell me which jets and shimms are for the VN750.....
