580 twin pipes

[nelsonhouse]

anyone recognize these twin pipes?
I bought them from someone that had them on a zr 580. I would like to know what rpm they run at. Or any technical information would be great.

Wow. Did some 580s come with stock twins? They look like a factory stamping to me.

No don't think any of the 580's did but the 88-90 ish 700 wildcat sure did ran like a raped ape !!!!don't remember what ron's they were happy at prolly 75-8500 but just a guess

 

[arcticridr]

That was suppose to be RPM'S not ron's lol

all i know is there not Black Magic,i had Black Magic twins on 94 zr 580 and they had separate stingers that angled and exited more towards the chain case!

Ran good until clutch and crank went. My 95 wildcat had a single. Couldn't keep a clutch in it.

Yup remember that problem well best solution was to turn the idle up a bit so they didn't beat themselves to death at idle Definately helped !!!
