TOPIC:

I got my sprocket from pmrcomponents.com precision metal fab racing

once you figure out what offset you are going to need,if you can't find one gimme a shout and i can help you out.

you cut the splines outta one,the teeth off another,machine a spacer and weldem together.





thats the readers digest version of offset countershaft sprocket fabrication !

hopefully you end up with something like this.

Leon, once I get my shock and swingarm completely mounted I will start measuring. I normally do everything myself but I'm not sure I can get the sprocket straight when making 1 out of 2....I'll probably be sending it to you! Thanx for the info everyone!!

quick update, waiting for my chain to arrive to figure out alignment issue. I have my sprockets cut up and ready to weld at whatever offset I need up to .80". I have also done some trimming on the GSXR front fender to make it look like it fits my idea of what I want. I have to shock mount tacked in but still need to make reinforcements. Found some rearsets locally on craigslist for $25 complete!! Actually came with a lot of other parts, swingarm, axles, etc. Anyone want a swingarm off a 2002 CBR600f4i? lol. Pics coming in the next couple days!

Mike,

I'm interested to see how the rest of this build goes Looks WICKED so far!

cool man. so far so good. keep us updated

Looking good so far! Great score on the gsxr parts too!

Hey looks good. I'm building a KZ650's rear end. I'm using a GSXR1100's rear tire.170/60 x17. Do you plan on using the stock 16 TEETH sprocket? Here's my offset sprocket. My spacer is 4130. Any issues welding 4130 to a heat treated sprocket? I plan heating them first then using 4130 filler rod.

Looks very good so far, really a great score on the parts and (no) shipping charge. A lot of times I see just the forks alone going for $200 much less all the stuff you got, it should help that you have both front and back ends complete. Paint/colours are very hard to suggest as it is so personal, for my build which will happen soon I hope I am torn between a no paint at all approach to any range of colours. Often waiting till all the parts are assembled will in itself suggest a colour scheme. I have seen a few traditional colour schemes but with really wild colour choices, check out what some of the top Japanese resto-mod customizers are doing, might get some ideas from that.

Good luck and I will be following this build for sure.

tiger1959,
no issues welding the two together.
i use er70s-2 filler.that way the weld has some elasticity,and less chance to fracture.

hi leon, first nice job on the bike...
second i was wondering if you can help out on a project of mine?
i have a project bike and was looking into welding a overlay (bigger) countershaft sprocket on a cut down original but worried that the heat treated 4130 sprocket will fail (crack) unless the part is annealed first before welding. have you done anything else ? and can you elaborate on machining the 4130 sprocket? speed/bit material etc as the sprocket i have is pretty hard as i think most are guessing about 50 or higher rockwell since a file will not nick it.
last have you ran any of the reworked parts with out any problems.
thanks in advance.....joe@ vcycle
project is 1968 w2 kawasaki engine in a 67 atlas norton slim line frame....if i can get past the sprocket ! ha

Good Fortune!
