Black Rhino Performance Chip Rocks!!!

Good morning, I am new to the forum. I'm 75 years old and love getting ATVs back to usable condition. I particularly like the 2006-2009 Arctic Cat 250 Utility. I currently own 6. The 2006 I am working on only has reverse and low gear. The "drive shaft" in the transmission is completely stripped where the high gear would mesh. Has anyone on here replaced the shaft. I'm told I have to split the case. I was hoping that someone on here could let me know how hard it will be. I already have it stripped down to where the shaft coming in from the clutch side is the only thing left. I was hoping I could just remove the driven clutch and drive it out from there. Directions say different. Any help would be greatly appreciated.

Which is more reliable? Shaft or chain drive? 

I suspect this bike may have a bad speed limiter. The part number for is 4060204. I found this one on ebay but it has a part number that is 1 number different. (4060203). It has the same LR44-2 and says its for a 94 Magnum 425. Will this one work on my machine or do I absolutely have to have the 4060204? Your advice would be appreciated. Thank you

Just thought I would start a poll on this topic manly because I'm not a fan of belt drives. Just want to know which you prefer.

When you and a group of friends decide you want to take a long group trip of camping/riding/overlanding, how far are you willing to drive for your trip? Right now, i find it really difficult to want to drive more than 2-3 hours one way.
