Necessary Addition when Increasing Horsepower on the Grom
About quality and texture: I am happy with the quality of the crankshaft support adapter from SP Takegawa. Complete kit that includes a steel radial ball bearing, machined aluminium bearing hold plate and shaft nut.About the feeling of use: A necessary addition for my latest higher powered Grom that I am hoping will be sufficient to keep the stock crankshaft in place until I am ready to install the SP Takegawa strengthened crankshaft.Products to buy together: A stronger crankshaft from SP Takegawa or Kitaco would also be desirable to purchase alongside the crankshaft support adapter for the ultimate crankshaft setup.Difficulty of installation: The process to install takes about one hour. Remove the left crankcase cover, flywheel nut and 3 bolts retaining the stator. Lubricant the ball bearing, push into the left crankcase cover and install the bearing hold plate. Install the shaft nut with a torque value of 64 N m and use the new included gasket for the left crankcase cover. Not difficult to do.Cost performance and comparison with other products: Good costing as you are getting a well designed product that could save you from also having to install a strengthened crankshaft depending on the horsepower your Grom is making and from what I can see the only other company offering a similar product is inferior to this design from SP Takegawa.About shipping and packaging: Sea freight was my preferred method of shipping due to the lower cost but currently unavailable due to Japan Post. Webike kept me updated on the status of my order up to when it shipped. The parcel arrived within the expected date range and was well packaged with no chance of the part being damaged.Any concerns, cautions, or advice when purchasing: If your engine has high kilometres then you should definitely being checking the runout of the crankshaft to ensure it is within the standard value before purchasing and installing the crankshaft support adapter.
