Rob, I totally respect your ability to fix things with any available parts "lying" around, and use your ingenuity to re-purpose them and alter them to make them fit and work. I wish I had more of that ability.
I only use my quad for 3 or 4 outings per year...hit the trails in the deep bush, in northern Ontario. I have yet to do anything to my 570, except I've changed all the fluids already (engine oil twice). I have approx 1200 kilometers on it (in 4.5 years), so I should be good for another 100 years approx hahaha. The only thing I've noticed so far is that one of the grease nipples on the lower rear A-arm is stripped and came out when I pulled the grease gun off of it, I will have to fix that. I love this quad!!
Take care buddy, nice talking to you, hope you're doing ok in this crazy times!!!
Dave
