I have brand new excel KTM hardparts 17" wheels with Pirelli Corsa's. The rear has a cush hub. When I shift in low gear at slow speeds, I notice some weird delay or slippage going on. Is this normal with a cush hub? Is it a clutch or tranny issue? My bike is an 05 KTM 525 exc. My clutch is hydro and when my bike is cold, it will run in gear slightly with the clutch all the way in. If I put it on a lift stand, the rear wheel will go while the clutch is in on startup. The delay or slippage only happens with the 17's on and after I changed the front sprocket to a 15...and only in low gears on startup. Once on the road with speed, there is no noticable thing going on.
Another issue is my front wheel. It has a tiny bit of side to side play. It's enough to notice. Everything is tight and I triple checked it for correct config and tightness. The play doesn't have any effect on my handling or steering and it's not noticable while riding. If I put the bike on the lift, and hold one fork and pull the wheel back and forth, it will click with movement. It's like 1/25 of a mil of play. Is this normal? My other bikes front wheels are tight...but nothing to compare with a motard size or type.
