jachuck49 Posted August 19, 2008 Share #1 Posted August 19, 2008 A friend of mine bought an '84 VR and had me take it out for a spin. It's a handful going around a corner or a curve.It wants to jerk rather abruptly when your riding down the road and hit a crown in the road or any wave pavement , like when they grind the pavement for resurfacing the highway.I'm not sure what to tell him. Any ideas? Thanks. Link to comment Share on other sites More sharing options...

ahoutzer Posted August 19, 2008 Share #3 Posted August 19, 2008 How are the tires? If they're flat on the bottom, or low on air pressure (same result -- flat on the bottom) then when you lean into a curve the bike does not have a round tire profile to roll over onto. Instead, it has to be forced off the bottom of the tire, over a corner in the rubber profile and onto the side of the tire. Is that what you are describing?

jachuck49 Posted August 20, 2008 Author Share #4 Posted August 20, 2008 I think I remember that the tires looked fine...didn't check the pressure. Is there a way to check for a loose steering head? Would you put it on it's center stand and see if you could "pull" on the tire and see if there was any slop in it? Link to comment Share on other sites More sharing options...
sarges46 Posted August 20, 2008 Share #5 Posted August 20, 2008 Yep thats a good way. Link to comment Share on other sites More sharing options...
ahoutzer Posted August 20, 2008 Share #6 Posted August 20, 2008 If you have a loose steering head, then you will probably experience a wobble at some speed -- 35 to 45mph maybe. Link to comment Share on other sites More sharing options...
SaltyDawg Posted August 20, 2008 Share #7 Posted August 20, 2008 Get the front tire off the ground and then center the handle bars. Then push the handle bars to one side and let go, if it hits the stop and bounces back off the stop the steering head bearings are loose. That is how we test the 2nd Gens, I'm assuming it would be the same. Link to comment Share on other sites More sharing options...
GeorgeS Posted August 21, 2008 Share #8 Posted August 21, 2008 Also, worn out Fork Springs. Replace with Progressive Suspension Springs !!! How many miles on the front tire? It might be damaged, even if not visable. Link to comment Share on other sites More sharing options...
a1bummer Posted August 21, 2008 Share #9 Posted August 21, 2008 I had a problem the shimmy shimmy shake shake in the front. I repacked the steering head that was quite dry. Still had problems. Noticed the tire wasn't worn evenly. I had to look real closely to find it. I assume the dry steering head caused the uneven wear. I put a new tire on last week and now it ride perfectly.
