The lighter fluid trick is just to tell if the valve and seat have a good seal , won't tell you anything about the guides & seals . You can turn the head and fill the port up around the guide and watch for drips around the valve springs but the oil pushing past usually comes out after it gets hot , not something I recommend one does with flammables .

Thought I did explain to how check for the oil getting past the guides in the other other thread , only way your going to find the problem is do the normal diagnostic checks every old mechanic does . Don't keep hunting for an answer you want to hear it could cost you a lot of money and grief in the long run . Advice is free man take it or leave it , been dicking with shovelheads for 35 yrs I specialize in them I still ride one daily .

 

Thanks for the help got bike back together and im gonna run that diagnostic check u told me where as no one else has give me that much info

 

Only a couple things it can be , sorry .

 

Well got it back together and i have run into problem i have never run into short of the plug or points out of adjustment has fixed b4. Is similar to bad plug will not start it trys hard backfiring everynow and then it blows out black smoke out that front pipe i have checked for fire on both cylinders and im getting it have checked pushrods 3 times and even bought new plugs checked intake for airleak. I have had bike 2years 1250 miles and im stumped i will add 1 last new detail on the bike when i bought it was ran dry off oil pistons welded to cylinder walls or vice versa it look nasty n there but as stated i punhed .20 over and rework heads with all new equip and that front has never been right but the back is a champ
