Not used my quad for several months now, in fact hardly used it at all since the last prop bearing replacement.
Anyway took my daughter in to town last night and decided to go on the quad.
Now it hasn't been moved for several months and has sat on the driveway under a cover all this time.
First thing I noticed was the steering didn't feel right.
The handlebar seemed to be slightly off-center to the right and I could detect it pulling slightly to the left.
Thought it must be my imagination.
Then daughter mentioned she thought she could hear a scraping noise as though I was dragging something underneath, so I stopped and had a good look but all seemed fine.
We carried on and got to town without incident, about 15 kilometers.

But something is definitely not right with it. It doesn't go round corners to the right as easily as to the left.
It's difficult to describe but there just seems to be more effort involved in steering to the right.
And the handlebar is definitely squint.
I wonder if it could be something to do with the 4wd system and the way the front wheels are engaged when in 4wd mode?

Probably going to have to take it back to the shop for them to look at.

I would take a really close look at the wiring for rodent damage....and make sure the battery is fully charged and can handle the load of the PS.
