With good advice from this forum and also others I decided to replace my old valve stem seals.
I was only going to do the seals and nothing else so I did just that and when finished started bike to make sure all was good.
I took off rocker assembly and used a harbor freight 10 dollar valve spring compressor and left the cams in place.
You do have to remove the left side back cam shield bolt that fastens to the rocker assembly. You can do this through one of the holes in the cam gear.
This went pretty smooth , however when looking at my cam belts I decided to go ahead and replace them, and might as well do the cam seals also.
cam seals I got from napa for under 8 bucks each. Belts I got online, gates belts for half the price of napa belts, with delivery in less than 48 hrs.
Pulled cam gears and plate behind gears ( yes after already removing plate bolt the hard way for removing rocker assembly and then reinstalling rocker assembly) and replaced seals. As I had just adjusted my valves after installing valve stem seals and realized how easy it was I decided to use a tip I read about for changing the belts. And that was to back off the valve adjusters all the way.This allowed me to easily deal with the right cam belt and I could just move the gear by hand to get it in the right spot and aligned. Also used the trick of after adjusting tensioner for left belt rotating crank 360 before adjusting right tensioner. Of course this is after both belts are installed . Worked excellent. Used the alternate after-market parts listed on this forum (thanks dan ) for belts, cam seals, radiator hose and radiator cap. All good numbers.
I would rather ride than work on bike but these things needed done and really the parts were pretty inexpensive. Might have to deal with radiator issues but not yet. :beg:
Of course after all that I am still getting some blue smoke under high rev deceleration that I had hoped the valve stem seals would stop. But peace of mind with new belts and seals is nice and with new single carb , it's time to just ride it.
Thanks for reading my ramblings,
