well,
I`m in chicoutimi at the holiday inn. O.K snow, not alot of grooming. BIG bumps which leaves me to why i'm here and not snowmobiling today.
Went to mount valin yesterday. rode about 70 miles and my drive coggs were skipping. Hit some big bumps but, nothing out of ordaire

Found my chassis was cracked around my chain case, drive coggs so misalinged it will not drive the track.
So, basiclly i learned that about 5 years and 6,000 hard miles on a 2003 mxzx 800 is all you can do with that sled. That,s what i came up with when trailering 2 hours back to the hotel.
So, if you want to run with XP's and you have a 4+ year old Rev, you may want to rethink your pace.
Or, rent a honda fit for $35.00 and go look at some new XP's or maybe a nitro at the dealers like me !!!!!!!
Oh, did anyone noticed that one of the areas were ski-doo claimed they 'added' strength on the XP's was the chaincase. Well, i did not think much about it then but, i understand now that they knew there was a weak area in the rev and i found it. Take a look for yourself. A much better design, for a reason.
Know anyone selling a XP 800R ??
Ever operate windows in french ???
