Offset front sprocket

[Suckerpunch]

Hello everyone, first of all I want to say this is an amazing forum with a lot of great info and help. I have been in the shadows reading, searching and studying. I do have a question that I hope someone can steer me in the right direction. I am getting a 95 GS500 and a GS450 bobber for $200 and I plan on making a streetfighter out of the GS500 so here is my question: I intend on using a GSXR swingrm (90-95) but I want to run a 170-180mm tire so does anyone know where I can get a front offset sprocket or one from another bike that will fit.
Thanks

GS1100 E from the early 80's is a drag racing favorite and hence has these available. Get more than ~1/2 inch offset and the bloody chain will saw through the frame.
Go past 3/4 inch and you'd lose the damn sproket spline ... heck you'd lose it at 1/2 inch too. That clip is a POS ...
And any more than that, you will need an outboard bearing.
Drill and tap the countershaft. Then put a bolt in it, then fit an outboard bearing, then machine up a brace for the frame and clearance it.
Fun.
Cool.

I was worried it would be something that drastic. But let me see if I understand correctly. I got you on the drilling and tapping the shaft for a nut instead of the clip, but would I then have to have someone custom make my sprocket for the offset? And then run the bearing on the outside with the brace to take some of the load off the output shaft?

As for as the widths go maybe I could find a 1/4 offset from the GS1100E and get it to work.

Well for 1/4 inch you could get away with just a sproket.
True offset stuff sometimes can be much much wider. Start getting wide and you start getting trouble.
Cool.

Thanks for the info. I think I am going to try and find a 1/4 offset and see where I am at then.
