Great Product Priced Right

A must have around the shop! We do a lot of carb work on all types of bikes that roll through for custom builds. If your doing any carb work at all your cheating yourself by not syncing them ! We picked this up as a replacement to another brand and are very pleased. Make sure you fit the dampeners to get a accurate reading. I placed ours a few inches from the gauge for easy adjustment while tuning. Highly recommend this tool.

Got my bike up and running

I had rebuilt my carbs over the winter, and there was just something left to be desired... syncing. I picked this up the other day, quickly found out my carbs were way out of sync and was easy able to get them back together with this tool. Great asset to have around for any older bike builds.
