Default Starter and Jackshaft problems please help

I bought a ultima thunderfire starter 2.0kw and a wildrider jackshaft assembly. Problem is when I put the jack shaft on the starter shaft the jackshaft bolt appears to be too short. I looked at another bolt I had and it is the same size. Question is it looks likethere is one size of threads in the starter shaft and then about 1/4 inch is a smaller size threads that the bolt threads into. I have tryed everything and it looks like some of the starter shaft needs to be cut off. Anyone ever had to do this anny help would be great. I posted this in primary area also but i thought the custom builders may have run into this.

There are two different bolts,one is a 1/4" bolt with threads and the other 3/16"bolt.go back to the dealer you bought the starter from,they just might have what you want.

I had the same "run-in".Early 90's jackshaft,w/late 90's starter.Very common as the starters look identical.However,the splined shaft of the early 90's starter has 1/4-20 threads,late 90s 10-32.So,what does one do in this situation-having a late 90's starter w/early 90's jackshaft?
Bikers' Choice offers a conversion bolt,which essentially is the early 90's 1/4" bolt,but on the end is 10-32 threads.Or you can have the 1/4" bolt machined/rethreaded at the end.
