Bert Rod down in Miami Florida is now making cast iron sleeved chinadoll cylinders.
This is a GREAT upgrade for those of you wishing for a more durable and forgiving top end for performance builds.

While I have not personally seen one of his jugs, I have long been waiting for this part to appear. It is the very next performance part I will own when finances allow.
The durability alone is worth a look, much less the potential for better porting allowed by the more durable jug.

Mods feel free to move this if it belongs in swap&shop. I posted it before I thought about it in my excitement!
 
Nice! I drew up an iron jug with aluminum fins and copper spacers 5 years ago but never got around to making it, as I decided to move to 4-stroke.

I've long felt that the original chinagirl jug is a piece of crap, made worse by the inconsistency of chinese production.
Looking forward to seeing results from anybody who gets one! I might have to build a chinagirl bike again! :D

this will set you back 275.00 us dollars for a stock 47mm bore........
Straight from his page.
 
275 might sound expensive but if you think about what he had to do to get these, I understand the price. Not saying I will run right out and get a couple. But others might.
 
Speed cost money. How fast do you wanna go?
The price is high because it's custom hand work by a talented machinist.
But I guarantee one of these jugs will outlast fifteen or twenty Chinese plated jugs....
For me, it's more about the durability than the speed potential.
 
Can't personally see my self going through 10 barrels on a CG motor.
But can also see how the hours start to add up when handcrafting something, this is probably a similar price to what you may have to pay for a high quality barrel for a motor cycle? so fair enough. But it's not on my shopping list.
 
Aside from the jug, the other weak point as I see it is the wrist pin. Already assuming all studs and bolts are upgraded tho. Between a good-quality jug, bulletproof wrist pin, all ports matching, all fasteners replaced with high quality, a chinagirl just might be made reliable for the long run! :D

Sure would like to see it. Seen wayyy too many fall apart over the years to be anything but jaded.
