Question for anybody who has used a motionpro syncpro.

[YZ125]

I agree, the sync levels on the last page are close enough, I just did mine with a set of vacuum guages, drove myself crazy trying to get it too perfect for about an hour. Also the closer the throttle bodies come to pulling the same vacuum the idle will drop, its normal because you are eqaulizing the butterflies valves, stopping one from trying to run faster than the other, just keep the idle at 1150 or a little higher as you become closer in adjustment. I must say, I rode today after sync & TPS adjust, the low speed running is much improved. When I turn my switchable TRE on the change is not as dramatic. I had now idea it was that bad out of tune.

Hey Wag. special thanks to you as it was your "knocking feel in the handlebars" post/thread that helped me solve my problem. cheers

Sometimes, I synch the wiff's Gixxer juuuuuust a little bit off. Makes for some happy times! ::
