Re: The Poor Boy - A Tale Of A CB550- Road Worthy
Hah, well I tend to think the worst before reason sets in. Right after I sold my 550, I thought the new owner over-revved it and floated a valve. After setting tappet clearance, he took it out for a spin and came back on 3 cylinders. I grilled him on what he did during the ride (poor kid ;D ) and we set about taking the valve cover off, only to discover one of the tappet adjuster nuts had not been tightened and worked its way loose during the ride, preventing the exhaust valve from opening at all! Simple solution, smack in the head, and problem solved.
Anyways, being air-cooled, I guess it depends on how long it runs while stationary. I would usually hook up a box fan or two if I was going to be idling it for any length of time in the shop. I don't think that paint would bubble from just heat alone though. That guy I mentioned on the sohc4 site had no bubbling with the same paint, with fairly extreme temperatures. The paint just turned from silver to a sickly brown. Definitely wouldn't hurt to pull the cover though, seeing as it's all of a 5 minute job.
