750 challenger in rocky mountains u

[Verno]

Just returned from Colorado with my 2017 cub 750.  I was very concerned since my last 3 sxs were Polaris.    Overall things went well.  Excluding any altitude over 11500 ft.  Removed the screen at 10000 ft and the tube to the intake at 11250.   From there on up could not get over 4k or 18mph.   Rode and handled great.   Other than cracking the cheap excuse of an exhaust  system the machine did excellently. Did 100 miles the first day out.

Received my spare airbox cover today.   Drilled 8 to 10 3/4 in holes on the cover for better air flow.   Next time I head for the mountains, I'll switch it out.
