Offset whole engine
Fuck, I have the biggest problem. Bought myself a weld on hard-tail for my Sportster 883. All was fine, the welding went perfect. The 200mm tire was put on, sleeves and sprockets and god knows all. Now, the problem, the only way to make the tiresprocket line with the primary sprocket (yes, I converted from belt to chain) is to offset the primarydrive...but there is no threads left on the shaft!! This will never work. So, have any of you guys heard about (maybe even done it yourself) offsetting the engine it self? Homemade motormounts?

Have you got the space available to put in a jackshaft to space the driveline out??? A lot less work than moving the whole motor. I'm doing this with my T120, it also helps to fill in that empty space you sometimes get with a unit construction motor.

I'm not really understanding your problem because I've never built a Sportster. I had to use a sportster sprocket on my shovel because they are flat and four speed sprockets are dished. The difference was all it took to center the wheel in the frame. Here's a stupid question, what if you switched to a 180mm tire? Would that give you clearance? Like my friend Steve says "there are no problems, only solutions".

I've just had a look at Shane's pictures---very nice!! Beautiful work mate, thats got to be the easiest (and nicest) way to go Jocke, like the inboard brake keeping the arse end clean too.

Built a sporty a couple of years ago. Road 6 customs weld on, 83 chassis with an early 90's motor. I was able to use an offset primary sprocket. late model 5 speed motors have available to.750 offset. I was able to use a .500 offset to run a 170 tire. Early 4 speeds have a lot less choices but a good machine shop offset my brothers early sprocket. 450 by cutting out and bulding a sleeve. Check my page, you will see my Hemi orange chop build there.
