If rust, then you should try to take some longer trips with the bike more frequently, so the oil can get hot enough to boil out all the moisture.
The shiny valve is likely oil that has leaked past the seals. Not uncommon with the regular seals and new oils when they get hot.
Cheers.

From what I can see, it looks pretty good. Unless thats rust in there...

i took a repeak......not rust, just discoloration...due to my own stupidity and rookie mistake, i ran this motor for quite a while with the cams out of phase...they were correct in relation to each other, but i was off a bit on the exhaust cam mark.....it should have been right at head level and it was about a half an inch higher...bike surprisingly went down the road well, but would nt idle for crap.....hence my schooling on vm26, vm28 bs34, 29 mm smoothbores.....i learned a lot about jetting and rebuilding and about people's character.......its all part of the learning curve......thanks for the input.....

never seen the brown build up that i can remember on the ten or so i've been in...no expert here but looks different than mine ever did.....smoke on start up is valve guide seals i believe...
i m gonna give the head a good lookthrough....i suspect problem is in there.....i dont want to throw any more money at this bike, but if i have to redo head , larry is going through it and its getting a mild port job......
