My 95 XR 628 is smoking 30 seconds after start up,in about 3 minutes it goes away.When you get back an it sit for 20 minute or more it will do it again.Now we have had it on the kick stand,standing up straight and leaning to the right.It does not matter.The valves have just been reset,Then we took it out ran fine,the next day rode again fell no damage but it started to smoke after that.Any or all ideas.Thanks Donn

Sounds like some bad valve seals to me. I've had experience with bad valve seals, my 83 600 I had to replace them ,72 Torino replaced them. You leave it sit the oil drains down in to the cylinder burns off then is fine until it sits long enough to get enough oil in to make enough smoke so you to notice it.A little oil never hurt anything so for now I'd just wait until you are pulling it apart anyways to put them in.

I would reccomend that you reasd through the manual and see if you understand everything and if you do go for it. If not then I've heard Ken's cycle in Mesa has a good reputation for honest, quality work.
