Good Morning, I have been thinking about not trading after looking and
thinking about my 450, and your advice has played a big part;-) Ok to
the questions, no I haven't a windshield or anything extra on the
bike, yet. Where are the bearings located and how to I check chain
tension?? I am waiting on my manual to come in. if the fork seals need
to be changed, will that make it shake?? Thank you for your time and
advice!!
