I don't know what the stock main jet size is for the old gen, the service manual probably has it. Here a chart for the size differences between manufacturer.

Josh, what's currently in your bike? the stock 105? or a 108? What are you doing to it that you think you need to go up to a larger jet?

Bigger is not better. Getting one step closer to the perfect mixture is better.

Stock is 105 but there is no reason to change jetting unless you have custom exhaust and/or pod filters. If you change the jetting without these things it will just run worse because the mixture will be to rich.

I have the 2 bros slip ons. But in some previous threads, there is cut out kinda like bogging when I push it quickly get the throttle to the "wot" or the stop point. The other day I was at 3/4 open throttle, then I jerked the throttle to fully open. The bike hicupet. Felt like it cut out only lasted a sec or so. I have a few other threads stating this problem. I did shim with one washer both needles. The low end is much better, it only happens at top end. No pods, just slip ons.
Even on a slow roll to wot it does this. I would say about %75 of the time it Boggs or hicupet at wot. So I figured going up one jet might help.

So you need a bigger main jet. I don't have experience with custom exhausts so not sure what size you need. I run 112's no shims with pods and stock exhaust.

If you have 105, one size up is 108, not 110...

So snapping is the issue huh? Have you checked to make sure your slides are seated properly and not cracked/damaged? Meh at about your float height?
