Attempting to adjust the valves, questions...
 

I decided I needed to adjust the valves, especially the exhaust valves. I've noticed just a difference in the tone of the bike, plus when it gets hot I can see wisps of smoke coming from the area of the exhaust pipes but can't tell exactly from where. Mind you I'm probably a grade below backyard mechanic so I followed the guide previously posted on the board.

Now I have 2 questions.... During tear down I decided to check the air filter and I noticed a coating of oil inside the housing, although the filter looks clean. Is this normal? Also I remember reading about the hose that comes out of the bottom of the filter housing (for drainage maybe), but the hose on mine has a plug at the end. Is that normal?

At this point I'm just trying to get the cover off on the left side so I can spin the motor to TDC.....but the cover isn't moving at this point. Is it really that hard to unscrew? Looks like whoever removed it last time chunked up the slot that one uses to remove said cover so I'm going to have to find something that will bite a bit more...

Well back out to the garage....look forward to some insight from you guys here!

Yes,it is normal to have a film of oil on the inside of the airbox.You remove the plug to drain any gunk from the airbox.When finished be sure to replace the plug or the bike will run like crap.I found that a small pry bar or a
large washer works well for removing the side cover.

Re: Attempting to adjust the valves, questions...
 

A slight film of oil is ok, but you MUST remove the plug at the end of that hose.
And, you must replace the plug after draning any water, oil, etc..
Removing the side plate is a bit tricky, or should I say that it CAN be,
if the tool you use doesn't fit well. It sounds like either
the PO (or you) tried using a screwdriver!
I found an old multitool for a bike that fits perfectly. The thing is about 80 years old,
so I doubt you will find one. :)
But, just by trying, I found that a silver dollar (Silver Eagle) fits perfectly,
as will a one ounce silver round. Just hold it with vise grips and turn.
The point is, find something big, curved, and the right radius and the job is easy!
I haven't found a screwdriver that will work.

The Silver Eagle is likely the cheapest tool in the tool box too.

I use one of the round spark plug gaper $1.00 at autozone

Thanks for all the info! I've yet to try any of the solutions as I started a job today...after 20 months of no job. Tomorrow is my day to do what I can to get the valves adjusted.

I did not have any luck using my previous McGyver methods to get that cover off....and yes the slot is jacked from the previous owner. Since I don't have a Silver Dollar laying around I'nm going to try the circular plug gapper and see what happens.

Another question - why is there so much gunk in the air housing drain tube? Is that all just a build up of old oil?

Thanks again!

Yes a build up of oil & water vapors from the crank case.
:) :cool:

Re: Attempting to adjust the valves, questions...
 

These days, that's pretty much the truth. And, it's a multi-use tool as well!
And, WW, you can use a Maple Leaf instead of the Eagle. :)

I actually get to see more Eagles in this area. Real Eagles with feathers and sharp talons. They fly down here from Alaska every year for the winter. The Eagle count volunteers started last week and have positive comments. Lots of early arrivals and the fish/food supply is abundant this year.

But isn't this an air INTAKE??? Wouldn't pressure flowing into the carb/engine prevent this? Just wondering..
