I read that everyone looks for 89 clip on's, i was searching through ebay and found some for a steal of a price, might want to paint though, i don't need them, I bought vortex, but I would have gotten these and saved 100 bucks.

Its a steal cos its like ... a piece of sheite ...
Its not a 89 clipon, its a homemade (OK fine shop made) hack job that was on an 89 GS.
BTW you see that wileyco some clown was trying to sell for $300 saying it will fit a GS ... yea he prolly sold the header with flange off to someone else and he's prolly complaining its not stock. Search for it, its prolly still there.
I tell you, some idiots are on ebay selling sheite ... one clown was selling katana stuff on craigslist and the damn thing turned out to be a GS ... and that idiot claimed the Front end alone was worth 250. I told him, I have a FE with $80 progressive springs and new but still leaky seals and new 15wt oil you can have for $100 and $20 will get you a wheel if you follow me home. Your FE aint worth $50 ... he was so mad he told me to get off his property. I said yea good. You prolly want $100 for your clump of weeds I stomped on and walked away.
Cool.

Yes that one, will not ever fit a GS without a flange. them flanges aren't being mass produced any more. I know, I made them. Anyway, I have a 100 other cans that can be fitted on with a slipper pipe.

Hey there buddha, do you have any progressive or straight rate springs you're wanting to sell???  Sorry for the thread jack!
