    Rear End Drifting

    Ok,

    So last night, riding my bike up the pch I noticed the rear end of my bike "drifting" towards the left. It was an ackward feeling like it was about to break out from underneath me. I checked the rear axle, it is aligned (based off the marks on the Rear Dropouts). THe Front end is good, bolts, etc in check. The rear shocks are new Hagons and are bolted tight. Anyone have any idea of what this might be? Rear Airpressure? Any input I would be super grateful!

    Thanks

    how old are your tires?

    could be bushings.

    Sorry,

    It is a cb 350 (1971) Tires are still new. The steerhead bearings have not been replaced, nor the swingarm bushings. The so called "drift" happens around 30-45 mph.

    I am going to start with the air pressure then work my way down the list.

    Thanks guys

    I would put the bike up on a center stand and spin the rear tire while checking the alignment with the spin and the alignment to the front end. Sounds like either the rear is bent (rim or swing arm) and/or the rear tire is not aligned with the front tire.

    new tires and you are counting on the alignment marks that weren't accurate when the bike was new to determine your rear axle is adjusted correctly

    hold your hands out while I splinter a ruler across them

    heck, most of the time when I actually have one here in person that has the same "complaint"

    I can simply sight down the chain and see the problem

    it ain't rocket science and installing new tires doesn't bend, break, or wear anything that wasn't already

    Hack, Are you a nun?

    I agree with everything you just said, but check tire pressure first. I have to admit I am a bad example, and don't check mine often enough. Whenever the back end gets squirrelly on me, low tire pressure is usually the culprit.
