Member Contributer CrazyInNYC Posted July 8, 2009 Member Contributer Share Posted July 8, 2009 my money is on one or more bent fork tubes. The runout limit is very small, there's a good chance you can't see it by eye. To know for sure, you have to disassemble the forks entirely, lay them up in v blocks, and turn them under a dial indicator. If you don't have V-blocks, then you can remove the front wheel (with the front of the bike supported) and if you want stick the axle loosely back through the forks to keep the lower tubes from spinning. Then loosen both tree pinch bolts on one fork at a time and just spin the Upper tubes in the trees, if the fork tube is bent you can just watch as the bottom (axle) end of the fork moves around. If the tube is straight the bottom won't move off center line, if it is it will move around off center as you spin the upper tube. Now check other tube. :fing02: Great idea! I'll descend into the man cave to try this and that. Oh, btw, here is the culprit: This monster is 1/2 beer cans deep. I wanted to put them inside for perspective, but this road is too busy and too dangerous. I was travelling in the direction of the shot here, so I got the worst of it. Ouch!

Member Contributer Rice Posted July 8, 2009 Author Member Contributer Share Posted July 8, 2009 Why were you riding the double yellow, in the rain? :laugh: IS THERE ANY OTHER WAY? Seriously though, there was a monster of a puddle and the middle of the road is its highest point :fing02: Link to comment Share on other sites More sharing options...

VFR4Lee Posted July 8, 2009 Share Posted July 8, 2009 A nasty little hole for sure. I'm not familiar with this "x beer cans deep" unit of measurement though. :fing02: Link to comment Share on other sites More sharing options...

Damn thing swallowed 90% of the bottle. Link to comment Share on other sites More sharing options...

Member Contributer Rice Posted July 8, 2009 Author Member Contributer Share Posted July 8, 2009 Last night re-checked everything. The forks appear to be straight as per BR's procedure. The axle is also straight. Sag is within spec. The only thing that is off is the front rim. It has about 4-5mm run-off as I spin it and look at its edge. So, I guess I'll be looking for a gently used front rim for a 6th gen. Hope this solves the problem. Link to comment Share on other sites More sharing options...
SEBSPEED Posted July 8, 2009 Share Posted July 8, 2009 Send a PM to cruzinaz, he owns a wheel shop and can straighten wheels, I'm also sure that his pricing is competitive. Link to comment Share on other sites More sharing options...

Hope this solves the problem. Please don't be offended, but at my office we believe in double check, double check, double check. The best double checking is done with a different set of eyes. Why don't you have a riding buddy whose judgement you trust ride the bike, look it over and give his opinion. Sometimes it just takes a different set of eyes to see something.

I too think that it would be best to have a second set of eyes (or other body parts for that matter :huh: ) on the bike, but alas, I don't know anyone close enough to my home base. I will send the rim out to be straightened as a first step. I am also looking for a replacement rim at the same time, b/c I hate to be w/o the bike for 2-3 weeks that it will take to turn the rim around, shipping and all.

I can lend you a front wheel if you cover shipping both ways! :wheel: BR BTW I don't think the wheel is the issue here! :goofy: The tire is much more likely to be the problem, a big hit can damage or break cords within the tire with no visible signs of damage, but the tire is shitz. :huh: Link to comment Share on other sites More sharing options...
Guest Posted July 8, 2009 Share Posted July 8, 2009 I second BR. While you're going to all of this trouble of a new wheel or having your old one straightened (rounded? - how about trued), put a new tire on it before you mount it back on the bike. When you have your old tire off, look at the inside for any damage. Also, press down on the tire (6" or so), rotate it say 30° and then press down again. The tire should deform to the same shape every time. If it deforms to a weird shape at one point in your press down test, you know the inside is screwed up.

You could probably even get a good estimation with the tire that's currently on the wheel. If you remove the valve stem, you should be able to see how the tire feels.

superfunkomatic Posted July 8, 2009 Share Posted July 8, 2009 actually the damage on mine was only noticeable at turn-in and at moderate speed. it would wobble or push the bike up on mid-speed right handers. i'd take BR up on his wheel/tire idea. swap one in and go for a ride. You would feel the internal damage as a wobble or vibration at speed, not at turn in. If the change of feel is not related solely to the new bearings, then my money is on one or more bent fork tubes. The runout limit is very small, there's a good chance you can't see it by eye. To know for sure, you have to disassemble the forks entirely, lay them up in v blocks, and turn them under a dial indicator. Link to comment Share on other sites More sharing options...
