not much to say here other than this is a good item to use when it comes to needing to sync your carbs easy to use as one would expect even if you are a novice such as myself I would reccomend it if you want to sync your own carbs,which is alot easier than most people say and i have no mechanical back round at all.plus shipping is fairly fast
Tried the liquid filled ones and they did not do the trick. These work great and can be adjusted so the is no needle bounce at all. 5-10 minute sync time. Worth the money. They also are half the price of the others and easier to use and maintain.
Bought this same tool many years ago. I forgot how valuable it is as a tuning tool. Works equally as well on sync'ing EFI t-bodies as it does carbs. My 99 Busa's (65,000 miles) idle improved immediately and gained 3 MPG the first tank of fuel. A must have for any biker's tool box!
If you are looking into purchasing a synch tool, then you have come to the right place!! it arrived nicely packed and ready for use. Dont be folled if the guages appear to be a little off. A quick connection to a single pouint of vaccuum will show that they are very accurate. the included restrictors will allow you to dial out the dreaded needle"bounce". It took 10 minutes to setup, set restrictors, and dial in the carbs. if you suspect that you're out of synch, then this tool is worth the investment. FYI... the local shops here charge $125 to resynch your carbs
