mrbret Posted August 3, 2007 Report Share Posted August 3, 2007 I am not expert so the issue could be me but I want some other opinions just incase:When I am cornering (no set speed) I lean over a little, not knee down or anything, & I feel the back end of the bike kind of quiver a little which puts me right off & so I end up cornering a lot slower than I know the bike can go. The quiver is kind of like when you ride over the tar snakes or a groove in the road & you get the little back end wobble, you know what I mean? I know you do.Anyway, would this be caused by something to do with the bike, e.g. tires, suspension etc or me being a big wuss & nothing to do with the bike?I honestly think it is the bike but what do you all think?If it helps any, One of my friends thinks that the last owner of the bike may have does a few burn outs on the bike as there is a 2-3" wide mark around the center of the tire.

SuperHawk Posted August 3, 2007 Report Share Posted August 3, 2007 i think its the tire, mine is the same way, i hate it, and my tire is basically near bald in the center and full tread on the sides, I bought it like this and have only put a few hundred miles on it, but I'm thinking its just the transition from leaning. if the bike doesn't sell asap then i'm doing a new rear tire.

Zecho Posted August 3, 2007 Report Share Posted August 3, 2007 My almost new Qualifier does the same thing on most corners. Quote Link to comment Share on other sites More sharing options...
ironbuttwannabe Posted August 3, 2007 Report Share Posted August 3, 2007 I think I would replace the tire and if that doesn't work look into your suspension. I was reading about the new z1000 and they were saying there suspension wasn't all that great on the older ones. Supposed to be fixing it on the newer models.

Chrisoh Posted August 3, 2007 Report Share Posted August 3, 2007 Sounds like the tire. If it is flat spotted you can get what feels like a wiggle as the tire moves over the flat spot.Other then that if it doesn't fix then I would check to make sure your wheel adjustments are dead on to make sure the wheels are aligned with each other. Also Check to make sure your chain isn't too tight as a tight change will not allow your suspension to work for you. You want at least an inch of play.The qualifiers are good tire I never had a problem with them on my CBR 900 even to knee down. Quote Link to comment Share on other sites More sharing options...
Benyen Soljax Posted August 3, 2007 Report Share Posted August 3, 2007 those grooves in the road fuck with everybody. i know as a beginning rider those things scared the shit out of me. i usually try to cross those as upright as possible and very quickly.

NinjaNick Posted August 3, 2007 Report Share Posted August 3, 2007 Yep if it's got a flat spot in the middle, then the transition over to the side of the tire would not be smooth and it will fuck up the feel. I've ridden like that before, and can't stand it. It's just the transition from center to side that is fucked up; uneven to say. The center tends to wear more when you live in Ohio than the sides of the tire. Quote Link to comment Share on other sites More sharing options...
XB12Ss Posted August 3, 2007 Report Share Posted August 3, 2007 I saw your tire on the group ride... It didn't look terrible. I'd start with the easiest of things, tire pressure. I have my tires at 36PSI hot. If they are lower the ass end wallows under me in the turns... If they are higher I don't get the same feel on the road and the tail wants to slide. From there I'd look at suspension. You're a big guy, having your suspension properly dialed in will make an AMAZING difference... I know from experience. Start with the manual and adjust your suspension according to it's recommendations. Quote Link to comment Share on other sites More sharing options...
Chrisoh Posted August 3, 2007 Report Share Posted August 3, 2007 For normal street riding I would set at 34-36 cold since in OH you don't need to drop the pressure any lower unless you are hitting the twisties with authority. Quote Link to comment Share on other sites More sharing options...

Chrisoh Posted August 3, 2007 Report Share Posted August 3, 2007 If I know I am doing some highway miles I will set it at 38-40 then drop the pressures down when I get to the twisties. Depending on how hard I plan on running or if I just want to waste the tires is where I set the pressures for the twisties.Actually I run the pressures up so I can spin the rear more for fun a practice Quote Link to comment Share on other sites More sharing options...
420gsxr1000 Posted August 4, 2007 Report Share Posted August 4, 2007 well i would say TOO LOW of tire pressure......i cant say shit about the twists, but i know when i run EXTREME LOW tire pressure, i bounce like a superball around any corner with a lean lol lol i hate it, but it makes for a huge contact patch for balance :0 Quote Link to comment Share on other sites More sharing options...
v65rider Posted August 4, 2007 Report Share Posted August 4, 2007 I would guess it is the rear tire as has allready been mentioned.I rode my step dads bike once that had the rear tire squared off and everytime I went to corner the bike it felt like it was going to slide out on me.Adjust the pressure and see if that helps but I think you really need a new tire, and you will be amazed at how much better the bike feels while cornering.

jermattak Posted August 6, 2007 Report Share Posted August 6, 2007 If it was that would it not feel like it all the time?thats what i was about to say, yes you would definantly feel it at speed, and would get worse as you get faster, maybe even better in the turns with all the weight on the side of the tire Quote Link to comment Share on other sites More sharing options...
mrbret Posted August 7, 2007 Author Report Share Posted August 7, 2007 In a straight line at all speeds it is fine, just when turning I feel it at a not very steep angle, it makes my heart skip a beat, quite worrying at times. Quote Link to comment Share on other sites More sharing options...

mrbret Posted August 7, 2007 Author Report Share Posted August 7, 2007 Thats what I'm thinking I was having a look around & think I may go for a Pirelli Diablo on the rear & a Diablo or Diablo Strada on the front.Not sure weather to go for the stock 190/50 on the rear or go for the 200/50.

mrbret Posted August 7, 2007 Author Report Share Posted August 7, 2007 The price is only about $5 more for the 200 over the 190. I was wondering if it would look any bigger (wider) than the 190? I'd like to have the money to go for a single sided 240 or something but that is to much. Quote Link to comment Share on other sites More sharing options...
XB12Ss Posted August 7, 2007 Report Share Posted August 7, 2007 Thats what I'm thinking I was having a look around & think I may go for a Pirelli Diablo on the rear & a Diablo or Diablo Strada on the front.Not sure weather to go for the stock 190/50 on the rear or go for the 200/50.Did ya check your suspension and tire pressure? I'd do that before forkin' out the green for a new tire... they're both free!Also, general rule of thumb as I have been taught is to keep your tires standard from front to rear... Mixing and matching two different tires, with different grip and other characteristics is probably not a good idea... Bottom line, front and rear are designed to work together and unless you really know what you are doing, you probably shouldn't fuck with that.I'd also go with the stock 190... The engineers put it on there in the first place for a reason, why fuck with it? Plus, you need to consider what the change in tire width is going to do to your tire height as well. A 200 tire is not going to fit on your rim the same way so the 50 sized 200 will actually have a higher overall profile from being pinched, despite both the 190 and the 200 being 50's... In other words, it'll increase the tire's diameter in relation to stock. Now the difference may be negligable in this instance, but in others it may not. It's surely worth considering though.That being said, if you do buy new tires, I give props to the Diablo's. I have them on my bike and they are pretty nice. I will say this though, they do square off REALLY quickly, but I have not noticed any problems in the twisties. I have over 3k on mine, 1k or so were really hard miles... I am guessing another 2k out of them... Quote Link to comment Share on other sites More sharing options...
XB12Ss Posted August 7, 2007 Report Share Posted August 7, 2007 Another thought too...If you are considering a 240 rear, then getting deep in the twisties is probably not your thing... Try out a sport touring tire like the Pilot Roads... They'll last a lot longer and are a high quality tire. Quote Link to comment Share on other sites More sharing options...
mrbret Posted August 7, 2007 Author Report Share Posted August 7, 2007 I'm not even considering anything more than 200. That would only be if I was wanting to throw a few $$$ into it so the 240 is not even in the picture. Quote Link to comment Share on other sites More sharing options...
