Probably oil burning off the valve stems
Check the stem seals are on the guides and run till clear

Difficult to get stem seal replacement wrong. Did you knock them down over the bit of the valve guide that sticks up above the cylinder head surface? They are a 'press' fit. Did you damage them in fitting? Rip the lip on one? Unlikely. How long have you run it for since you replaced them. May take a couple of miles to burn off the oil that is bound to leak down during the fitting process.
The other possibility is that they weren't the problem and it's bore/ring wear. Does it smoke on overun and give a big cloud as you accelerate away? Seals. Or does it smoke all the time, the harder you drive it the more it smokes. Rings.
Is it grey/blue oil smoke or black overich mixture smoke like a diesel. Or white 'smoke' or steam like the head gaskets gone?

took it apart again and the stem seals were of again, god dam rl31 cam with its dubble spring systerm apparantly the are known for snagging the seals and pulling them back off, ive been told by burton to glue them on but thats not so easy when im trying to do the job with out removing the head 3 times apart now and still no look,

( i mite have to job this one out) any one

Thinners to clean the guides and superglue to stick. Use a suitable tube drift like a long 10mm socket to tap them down onto the guides.

can i use carb cleaner with out degrade-ing the rubber

[Longboarder]

I would gently remove them and get them in the sink with some fairy liquid.
Perhaps look at upgraded but single springs from Burton, Kent or Piper and loose the double valve springs.

i got in tuch Burton's but they didnt offer any type of upgrade for the RL31cam when i surgested dumping the second spring.

Both Piper and Kent do a range of valve springs. Pipers are single and used for their range of cams up to their 320 for the pinto. Kent the same. Burtons have hold of the wrong end of the stick or can't be bothered thinking about the problem. However if the problem is now fixed don't worry.

Never had to glue them on !!in all my time . They can v akward to fit and get square , and don't try to refit as they will not stay on! mower man

Narrow stem seals came with my RL31 cam kit,
I believe they are similar to CVH stem seals
