Derailleur/shifter compatibility

[Schwinn-Locura]

I hope I selected the right section for this...

Anyway, I just ordered a Jackshaft for my bike so I finally need to get my gears working right, and I haven't used them since putting the engine on my bike over a years ago.

So, this is where my question comes in. I just seen a Sram X9 (9 speed derailleur) on Ebay and I was wondering if a Sram X9 would work with a Shimano 8-speed shifter. I would call my local dealer but they don't open until Monday.

I don't see why almost any derailer would work, they all have limit screws built in and have the same function.
You can't find one off a junk bike?

You will get a better answer about shifter-derailleur compatibility from a mountain biking site like MTBR.com IF you do not tell them you are building a motorized bicycle.

Seen one used on ebay for under $20 so I thought it would be worth it. An X9 would last the life of any bike I'm sure.

True. The only thing is I forgot my password and I'm using a different email. Didn't feel like making an account.
