GRUBEE SkyHawk GT5A 66cc Angle Fire Slant Head Bike Motor Kit
- Product Review (submitted on July 10, 2013):
Just purchased the GRUBEE SkyHawk GT5A 66cc Kit. It was my first build although I did have another unit to compare it to. Total time was 3 hours, including testing. It took about an hour to make sure the rear sprocket was aligned perfectly. The first trip out was 10km and it worked great. The motor has good compression (10 hours so far) and I expect the performance to improve after break-in. The only adjustment outside of factory I can see is to change the carburetor jet for proper location (elevation) during full power. Of course it always goes to the shop for inspection after every ride. I will be ordering the performance parts to go with this kit right away.
