I went with sprocket on the inside. When you put the engine on your frame, you'll see that you need it this way. Allows better placement of the engine Left/Right and better balance.
I had same problem until I put spacers (washers) on the handle bar mounting bolt to snug it to the frame. I could see it needed this because there was play up and down along the mount. Now, no more rattle, shimmy, or popping.
Has anybody put an AGK header on their DB30 (w/ 6.5hp clone)? I'm wondering about clearnace with the straight, candycane, or other styles they sell.

Instead of a flap wheel, I used a dremel sanding drum bit to open up the bore on the clutch just a smidge. Finally got this thing on the stock engine.
I think I get about 10% more torque on the low-end during take-off with the new clutch. 11 teeth instead of 12. Also higher RPM engagement...
Just bought a dremel flap wheel, but it's too big to fit in the 5/8" shaft for this clutch. Will keep looking.
Sucks a big one that I may end up buying $30 worth of hardware to get a $24 clutch on the bike.
no luck
I sanded off the bore on the clutch, and still doesn't fit. lightly tapped it onto shaft with rubber mallet, and it goes on 1/64" at best. Feels like a lot of metal will have to be ground out of the clutch shaft to make this thing fit.
Tried it on a 2nd stock engine shaft, and same...
I just got a Max Torque clutch (5/8") for the stock DB engine. The stock clutch slides nicely off the crankshaft, but the new clutch won't go on. Even with key removed from clutch, no go. Caliper shows shaft is 5/8" and clutch ID is 5/8".
I tried sanding the crankshaft down, but still no...
My new Max Torque (#35, 3/4") clutch has some play along the crankshaft of a new 6.5HP Lifan engine I just bought from HF. Has anyone seen this before? I guess I'll look for a washer/spacer to keep the clutch from slopping back and forth along the shaft.
Bolts are "M6×20" according to parts list.
