Motion Pro SyncPRO Carburetor Synchronizer Tool for ATV, Dirt Bike & Motorcycle - White (One Size) - Perfect for Carb Tuning & Engine Performance Optimization

Quality product that is easy to use and very effective. Pays for itself after two uses. There was other ways to rig up some home made tool to try and achieve the same effect. Normally I am all for this but quality tools make a job go by quick. The cost to get your TB sync'ed at a shop is much more than this product so I was glad to buy this tool.I'll always own a bike so it will pay for itself!very happy with product came quick and in good shape. thanks guys you saved me a lot of money ;)Works well, I'm used to the electronic ones don't lose fluid over time "I live in the desert" or cant be sucked into the engine "over revving" but it works well and its affordable.The fluid dries out in these syncpros. You can take the hoses off and cap all four tubes to slow the evaporation, but after about a year the evaporation will cause the colored water to gap badly when you try to use the device. On the youtube instructions from motion pro, he says max 1/4 inch air gap at the top of the column by the screws, or you need to refill the fluid. The waiting for shipping and paying more for shipping than the fluid costs, is a pain. Rather have the old mercury models, no evaporation.
