Did some tune up items on my CB today. I have about 850 miles on the bike. I have been noticing here of late the bike is shifting a bit rougher between gears and is a bit jerky coming out of corners when applying the throttle. Checked my chain tension on the center stand and my chain was at the maximum of 35mm. Loosened the axle nuts and tightened the adjusters 1/4 turn. This brought my chain tension to the min of 25mm or 1". After tightening everything down to spec, I took a test ride. Wow, what a difference. The bike shifts ultra smooth again and no jerking coming out of the corners when applying throttle. Hard to believe this small adjustment made this big a difference.
Tip I learned for checking chain tension when I had my Triumph Bonneville. Take a 3x5 white index card and put a straight line at zero and then another at 25mm for min and another at 35 mm for max. Hold the card behind the chain at zero and check our tension by pushing the bottom of the chain up near the middle of the swing arm as directed in the manual. If the chain ends up between the 25mm and 35mm line you are within spec. Simple easy gauge for the back yard mechanics out there.
