Thanks for everything guys. I talked to him and just told him to 212 swap it. I already ordered the max torq clutch and the motor adapter plate. I said the same thing as you guys, it’s not worth it and to just swap it. Last question. Will I have to lengthen the chain on it for the new motor? Or will I have to shorten it and I can reuse the chain?
Need to know how many teeth on the clutch you ordered, & what the rear sprocket tooth count is also.
The DB -30 rear sprockets are usually 70 - 75 tooth.
Gearing I would recommend would be 5 - 1 with the 212.
That would be a 13t clutch & a 65t rear sprocket.
I guarantee that will still be plenty.
You can get the 65t ''6 bolt hole'' sprocket on like Amazon ect.
Going with a larger rear sprocket than 65t with the 212,, you are going to have a ''wheelie machine'', with how much you Guys weigh,, especially if the rear sprocket that's on it is 70+ tooth,, & the clutch sprocket you ordered is ''less'' than 13t.
I don't use motor mount adapter plates either.
I just cut off the front drain plug flush, & mount the engine all the way forward up against the foot peg cross frame tube,, with drilling holes in the stock motor mount plate.
Not using an adapter plate will also help in lowering the center of gravity on the bike a bit, & save weight.
Added,,
The Max torque SS clutch generally comes with the ''silver'' 2,200rpm spring.
The best spring as far as I & most others are concerned, for ''larger'' engine ''Mini Bikes'',, is the Max torque 2,550rpm ''green'' spring.
It's night & day smoother & safer engagement for all around riding.
There is a Max torque vid & others also,, for the spring changing procedure.
I highly recommend doing it.
