Random questions about the bike - Are these normal?
Ok, so, I have a couple questions about my bike that I'm trying to figure out. Basically, if this stuff is normal for the 250 or if there is an issue.
Bike is a 2008 with 14k miles. I got it several weeks ago, and put on about 750 miles so far. The bike has plenty of mods from the previous owner. One of those being an HMF pipe. When I get up on it hard, shifting at high RPMs (I've ridden dirt bikes for 18 years) and then drop the throttle, I hear crackling/popping/backfiring from the exhaust. Nothing terribly loud, but still present. Is this normal? When I hit the throttle or chop the throttle, there is a lot of jerkiness. From my research, this is normal wear and I need to shim the rear. Not really worried about it. When I'm hitting a turn, the front feels "floaty" and wiggly. A little too floaty for comfort. My buddy has a 2009 250R with less than a thousand miles, and I rode it for about 2 miles. IMMEDIATE noticeable difference. I felt way more comfortable on his than mine. Also, his front shocks seem much stiffer. Would looser shocks cause this floating feeling? Too high/low air pressure? Crappy/worn tires? Go easy on me, I'm still learning street riding lol. Keeping in line with the front end, the bike has clipons. The PO put these on as well: http://sportisimotorsport.us/index.p...products_id=15 Should I attempt to adjust them? How do I go about doing this? I'm sure there's more questions that I'm forgetting, but this is a good start. Just trying to get the bike set up to my likings. |

Are you running the original tires? If they have 14K on them, or are for some reason flat down the middle, this can be the source of your poor handling. You're basically cornering on a narrow ridge when your tires are flat down the middle section. New tires with a rounded center section will feel better in the curves.
My 650R had the original tires on it, & I noticed that I had to fight it to lay it over in a turn. I put on the new tires, and now it lays over like it should. |

Tires / Tire pressure. Once those are sorted, then see if there is still such a noticeable difference. What pressure were you running front/rear?

The front looks fairly normal, but if you'll notice on the rear....the tread depth looks way deeper on the outside than it does down the middle. On a new tire, the tread depth is pretty much equal across the entire tread section, which makes for a good cornering feel & easy leaning. That wide flat area on the tire will make the bike reluctant to lean, and when it does, it's riding on a narrow strip of rubber between the flat area and the round edges, which can make it feel squirrely.
I'd get rid of that rear...you'll likely notice a big change. It's not necessarily dangerous, but it causes bad behavior in turns. |

Correct me if im wrong but in the picture of the rear tire, are those not wear bars down the center of the tire that are flush with the tread. That would signify they need replaced, I'm thinking youll be much happier with some new tire, or at least a new rear.
