I'm looking for a more reliable replacement transmission for my Grubee 4G transmission. Anyone know of something more reliable for less than$200? My HS 142 engine still runs fine even better after replacing the crappy stock carburetor with the 2 stroke NT racing carburetor. But after fixing my 4G T belt transmission it broke AGAIN a month or so after the repair! the same way to. The clutch bell broke clean off the shaft while I was driving at 25 mph which isn't even the bikes top speed & I was driving on a smooth, level road. From the looks of it the clutch bell & shaft seem to be made out of a cheap flimsy brass material which is probably the stupidest material to make engine parts out of whether its for a high RPM machine or not. I get they are trying to build this stuff on the cheap but gesh! At almost $150 for the transmission alone I would expect at least a better built clutch bell & shaft which is a pretty crucial component. At least bolt on the clutch bell instead of welding it on there in such a flimsy way would have been more preferred.
