[raginyamaha]

Got a 08 nytro rtx lookin to extend it a little and put a 128 in ulmer kit on it. also if i do that a cobra track (1.352 lug) and 1.375 studs anybody know any issues with the combo or issues with the parts by themselves? Especially with clearence for the studs.

I extended my S.E. to 128", but used a Hacksaw instead. I do have a few very small and short marks on the rear flap bracket. I do run my track loose and that may be the reason but just a word to the wise you may want to add a 1/2" of material to the tunnel protectors at the rear.

I have been running the 128" cobra since day one. I am studded down the middle and have no marks on the snowflap bracket. I bent the bracket up just slightly to prevent this. I was told to do this by Ulmer. I would have gone with the 136" but was afraid the sled would not fit in my enclosed trailer with the tunnel extension. I really like the 128 but cannot compare it to the 121 because I changed tracks before I rode it.
