If my timing chain is loose, is it possible for it to jump timing while cruising at low rpm's? The reason I ask is I have this issue with my bike that it runs great for the most part but every so often it will mis or backfire when I am at 1/4 throttle and then when that happens the engine will start popping and backfiring from the right cylinder only. This only seems to be evident though when I am off the throttle coming to a stop; it seems like a timing behavior. After a few starts later, it will run fine again. If this is possible, how can I check and adjust my timing chain? I have a CDI ignition on my bike btw. Thanks.

I'd say the idle screw needs adjusted on the right side. Sounds like it's too rich, so try turning it in a hair. Just my uneducated guess tho

just check your valves. or tune your right cylinder. or get new plugs. the chances of your chain being loose is between 0 and 1.

or float height has changed.

try running some fuel cleaning additive through the tank to see if it helps
