which one is best for the 650? i have a 'motion pro' model and its works like shi*. the fluid inside the tubes always gets seperated and lies everywhere in the tubes. it never seems to pool back at the bottom. anybody have good results w/ another brand, maybe gauges? thanks for any help, tom

I have four cheap gauges I bought from ebay a couple of years ago, I paid $60 back then and I have had no problems at all with them.
I tested them at work on a known vacuum source and they were all spot on.
The biggest problem I have is getting them back because all my friends keep borrowing them.

Just do a visual sync and that's it.
Vacuum sync is fine tuning and maybe is helpful for racing applications.
Moreover you only benefit if everything else is set all right.

Have a look for your specs (cam chain, valves, ignition etc.), clean your ignition related contacts, lubricate the advancer and be happy.
No need to play around with sync tools to get a good idle around 1000 and a reasonable throttle response.
