2- 27mm carbs. This is all conjecture. It was a long drive thur Atl on Friday night traffic, then back. 4-1/2 hrs, with a stop at Jersey Mikes Deli. Incredible reubens BTW, but I am SURE glad I live in the country!! It is still on the trailer, she'll wait until the morn. Same size tires as the 200GY-2, 15 inch rear. It looks like a better dual sport than what's on the Vento. Almost new. 2,256 miles on the od, though that could be wrong. I'll post pics tomorrow. I hope the engine will fit the UM frame, as I have a title for it.
Do you plan to put better, off road tires on your Zong/Vento?

Yes I do. The rear has maybe 30 % tread, but the front has slight dry rot causing it to oscillate at anything over 40mph. A bit scary entering a curve. I will replace the front soon, as it's much easier to find an 18" dual sport. The rear tire on the Longbo is the same size as the Zong. It's a Duro. The tread looks great, not quite dual sport. I'll post pics in the morning. I believe it was one of the tires mentioned in your tire thread.

You have lots of good choices for the front wheel. The rear wheel is an entirely different matter.

You might be interested in this Duro 627 tire for sale on eBay.

http://www.ebay.com/itm/Dunlop-K627-...180661?vxp=mtr

You can also check if this vendor in Ontario can sell you a CST C7208 tire in size 130/90-15.

Great find. Thanks Spud! The sidewalls on the Dunlop looks like it will handle terrain much better than the Duro.

You're welcome. I always enjoy the opportunity to help a fellow Zongite.

Awesome score! i wish we had stuff like that around here. The only road legal China bikes I've seen locally are 200cc DS Honda clones, and they're rare.

Mmm, reubens.

Looks like good bobber material. At that price, you certainly wouldn't mind chopping it up.

Most definitely. I think the seat on the kids Schwinn bicycle in the picture is higher!

Dig the flames!

I presume that you're not going to run open exhaust, and the engine will smarten up considerably with mufflers. The carbs might not be as bad as you think.
