YES!! I have had to trim the case saver a bit.
If you have bad swingarm/axle bearings don't go 15. If your a maintenance guy and everything is in great shape, a 15 is fine.
15 fits, bot no guard, just the cover and the oil orifice is right where a thrown chain on a 350X makes a hole.......
I think I run 14/38, could be 36 though as I run 20" rear tires.
I'll look tonight when fkn around.
Use a GOOD set of sprockets and ensure from the guide to the chain you are 100%.
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
