Guys,
has anyone tried turning they're crank sprocket inside out to gain more chain clearance?
What will happen, will the sprockets wear quickly?
Maybe chain pops/slides out?

It will be out of alignment im guessing but ive done a test fit and its only barely visible, if i didnt know i might not of even noticed it.

I just wanted to do it for one track day as i want to use a wider rear tyre then i have atm, and after that i would get the rim laced properly, but if its going to do some major damage, then i would rather not.

cheers

As long as you can space the wheel out the same amount there is no issue. As someone who ran a set of marchesini's on a streetbike without realizing the left spacer was improper and sprockets were not aligned, I can tell you it will eat sprockets and chains proportional to the distance out of alignment. If you have a chain slider, expect increased wear as well.

What's plum on a supermoto anyway LOL.

I had to reverse mine to compensate for my rear sprocket being offset by about 2.5mm.

I think if we were pushing the horsepower of a sportbike, it would be more of an issue really. But, you are correct, it will wear both your chain and sprockets out more quickly. Luckily for use sumo parts are pretty cheap.

yea I flipped mine and added spacers on back of sprocket so my 160 pirelli slick wouldnt hit the chain as bad on my 5 inch rim

I have the same setup minus the slick, but a diablo. I still had to dish my rim over a smidge, but I have zero chain contact now.

I run a countershaft spacer and a homemade slider, chain and sprockets do seem to wear a bit faster, especially clearing a 160 rear. I am running Marchesini wheels as well, there spacers seem to work fairly well.
