Looking at my cool head options and ran across this...

Anybody run this? I like the two piece design...

 

Comments? Opinions?

That's reasonable for an OEM cylindered engine. D&D makes good stuff. I wouldn't put it on a monoblock cylinder though. :thumbsup:

i've just had bad luck with thier products. i had a zr 900 (snowmobile) that i bought a D&D 1010cc overbore kit for. installed it right to thier specs,tuned it ,clutched it and cursed it.i tried multiple set-ups on this engine and nothing made a difference. i was getting blown off by stock 900s on the lake. after dumping over $3500 plus taxes and shipping, i wasn't happy. i talked to other people that had them and no one was getting real great results out of this kit. about a year later i was reading an article in American Snowmobiler magazine about the annual" trail mod shootout" they have. in the article was featured a 1010 kit. the results in thier drag runs were consistant with mine. slower than stock. i also had a buddy that bought a D&D 1147cc kit for his zr900 and it was also getting waxed by stock sleds as well as some "not so stock "sleds but with lesser mods. maybe D&D has improved on thier quality and customer satisfaction, but they,ve definately seen my last dollar!
