I have a 2006 Crossfire 7. I just got back from a trip to the UP. After day 3 I noticed a vibration around 60mph and it gets worse the faster you go. Anyone have any ideas on what it could be? Everything is fine below 60!!
You burnt your belt, or you bent your drive shaft... check for missing studs or section of track inside and out to see if your track is off weight, but i doubt it.
It will be something in the drive line obviously, check obvious spots... take your belt, put it on an extremely flat surface and put a flashlight on the other side of where your eye is and look for light shining underneath it. if there are wear spots you will know. the other (major) problem it would be is that pricey little drive shaft you have under the tunnel. of course there are other little things it could be like a broken drive sprocket, or a wheel missing some rubber... check your belt first and go from there...
Could be your track. I have the same issue and have read that it is something with the tracks. It has not been bad enough for me to worry too much yet. I have a 1000 miles on my six. Look around hardcoresledder or arcticcatchat for more info. This and the tunnel issue have been discussed extensively.
hear that simon. make sure you haven't lost a cog on your belt. if you have gotten stuck and slipped the belt the sides of the belt may have a narrow spot. it should vibrate from engagement on up though. the bearing is a good suspect. most of the time the drive clutch will get hot.
check your hyfix. as they wear down they develope a wave type pattern depending were the wheels are placed. clips ride smooth till you get some good track speed, then start to vibrate as they pass the high and low spots.
