50mm bore kit

These are questionable.
A great price BUT the ring gaps have been wayyyy too wide (.020 or more) on all the ones I have bought. I have been buying these and replacing the piston and rings with the Hoca piston and ring kit from Parts For Scooters. that brings the price total up to about $90 but they have worked well doing this.

yeh i bought one of these & 2 mates also after seeing the results i got with mine and a few more goodies!
my baotian tops out over 60mph with this kit, decent cdi, coil, & trans mods - first away from the lights and straight to 45 / 50 mph & doesnt really slow on hills.

i was more than impressed with the quality of the kit for the price... even with postage to uk it was a good buy... and it came with a full gasket set & uprated oil pump... and new head c/w valves.
the ring gaps on the ones i've seen were 13-15 thou which imo is well within tolerance.
the only issue i had was the top ring groove was a bit tight & stuck after a few 100 mile... sorted with a hacksaw blade at the roadside lol!

recommended tbh

Got another one of these kits in and the rings were ok on this one. I guess its a shot in the dark as to if the rings will be ok or not so be prepared for that if you buy one of these kits.

I just installed one of these and minus the piston and rings its a good kit...I to am going to replace the piston out for a hoca. my problem was my rings didn't seat at all...even after a few biker tricks.
