1.45 studs - clearance with 9 tooth drivers?

[BLUEBALLER]

thinking of running a studded cobra track next year. want to know if 120/144 1.45's will fit down the middle with no problems.

anyone run 1.45's on their nytro??? If so, did you have to add material to the front heat exchanger protectors??

I ran those in my Apex and worked very well without problems.. Can't see why it would be an issue on a Nytro as it has more clearance.

I'd like to know this as well. I'm thinking of doing the same thing.

just snow checked my first yamaha what is the stock tooth driver on the fx nytro im thinking of doing the same thing

The stock driver is a 9 tooth/2.52 pitch. Two guys I ride with have 08' RTX's and ran 1.325" studs. They had a few marks here and there, not on the exchanger but other flanges around it. These were stud boy and Woody's studs. I think you could get it to work but I would check and shave down any interference areas before the studs do it for you. Worst case maybe add a 1/8" strip to the protectors.

I ran 1.45 Woody's studs for 1,000 miles this season with no issues. Just make sure your track tension is set correctly and you shouldn't have a problem.

Track Tension

If I add the extrovert drivers to run the track a little loose are studs going to be a problem? These clearance issues are really starting to have me concerned.
