I cleaned the engine and checked. The oil seems to be coming out of exhaust port 4. The exhaust colloars are wet with oil and there is no oil coming from th4e surrounding areas. There is no leak from head or cam cover gaskets. Tappet covers were checked and no leaks there either.
While I admit to the rare possibility the oil could come out of the exhaust. I find that very unlikely. If you are confident that each and every seal is perfect. The remaining options are:
Cracked head
Very bad exhaust valve guide. However, there should be blue smoke from exhaust and the inside of the exhaust coated with oil, as well.
Leaking tach drive seal? Have you cleaned it, then applied foot powder and watch for where the foot powder begins the absorb oil? I expect there is something you've overlooked.
Stock needle postion is that the needles have never been out to my knowledge and the tabs show no sign of ever being unbent. I would check them but I truly am not sure how to safely get them out with the carbs on the bike and I need to ride to work in the morning.
Have you owned the bike since new or from when it was in known stock configuration? Who pod on the pods?
New 100 mains installed with new O-rings.
Can you confirm the orings were correct and sealing correctly to the carb tower?
I have not pulled the emulsion tubes.
At this point, I'd consider that the prime suspect for running rich.
The passage between the air jets and tube will flow compressed air and also carb cleaner. I'll need clarification on the term "prove"
Proving involves testing liquid flow between each of the four exit points in the pilot circuit. Perhaps you did this? There are two air jets. One feeds the pilot, and the other feeds the main/mid emulsion tube cavity.
Can you confirm that each spark plug shows the same deposit pattern as all the others?
Just a bit of info for TT. I just did a compression check. 130 across all four. Bike was warmed up, throttle and choke open. All plugs out. Using a standard compression gauge from an auto parts store with 12 inch hose. I get the same reading with oil added to the combustion chambers. Maybe a leaking valve stem seal?
Almost certainly is not a ring problem. If guides were an issue, you should also have reported blue exhaust smoke.
Unbind the slide lifter arm from the common actuating shaft (Hex bolt).
Disconnect the lifter arm from the ball and socket slide connector.
You will then have access to the two screws that connect the slide to the lifter base.
When those are removed, you can twist the lifter base pad for slot alignment and extraction of the slide or needle is now possible.
You will have to vacuum sync the carbs after reassembly.
Cheers,
