Brother in law wants to put a 1 1/4 on his ultra touring but the owners manual says its a 134 will a 136 fit or do they make a 134 in track with longer lugs

Thanks

I believe that 134 is actually 133.5. Half-inches may count here. Look at it this way--for every inch you move the rear axle (via the tensioners) you take up about 1.7-1.8 inches of track. Since you need to take up 2.5 inches more than stock, make sure you can move that rear axle about 1.4 inches. Other ways to take up some extra track is to put on larger drivers on the track shaft (if possible) and larger idler wheels on the top of the rear arm. (But if you're gonna pulling out the skid anyway you might as well just drill new holes for it 1.5 inches rearward from the stock position.

What did the elm say to the maple?

Geometry!
