Valve adjustment without removing pickup coil cover?
« on: August 29, 2017, 09:26:49 pm »
I noticed in Steves video on valve adjustment he just tapped the starter to turn the crankshaft. Am i missing something or does this mean i can just take the valve cover off and not worry about lining up the TDC mark eyeballing the position of the lobes.

Pull the plugs to make the engine turn real easy, good time to check or replace them anyway.

There's also a little plug that let's you see TDC without having to take the whole cover off.

If you have the shop manual, check section 4-20.  You can use the marks on the cam sprockets when they line up with the top of the head.  Looking at the sprockets, with EX and IN markings upright, and the mark (line) is lined up with the head, adjust
Intake : #2 and #4
Exhaust: #3 and #4

Rotate engine until EX and IN are inverted, and the mark (line) is lined up with the head, adjust
Intake : #1 and #3
Exhaust: #1 and #2

Just ensure that the valve you are adjusting is on the base circle of the cam. I haven't done my Connie yet but on all the others with the plugs out bike on the center stand or Jack and in 6th or top gear it is easy to reach out grab the rear wheel and rotate the engine to the point you need...

Just ensure that the valve you are adjusting is on the base circle of the cam.

That's all you really need to do. Just turn the motor until a cam lobe faces away from the lifter. Adjust all the valves that have the lobe facing away from the lifter, then turn the motor until another lifter is on the base circle... adjust some more... turn again... Keep a chart of which ones you have done, so you don't miss any.

Leave the old cables in place if you haven't removed them yet. It makes it a lot lot easier on the side of the road to hook up your spare and they won't take up space elsewhere. You may want to put them back in place at your next service.

Make sure to wrap the ends with good black tape (3m) to keep crap out.

That is a really good idea, I will do that when I install the new cables I have waiting.

I have to ask, Steve J you mean to wrap ends with good electrical tape of the spare set you stow away and not to add the tape as part of an install, correct?

That's assuming you are replacing cables while the old cables are still usable. Preventative maintenance!

I always used the starter bump/plugs out method to position the cam lobes for adjustment. I start with #1 and watch the piston rise on the compression stroke (after intake valves close, watch piston with a flashlight). As others have mentioned, you do not have to be precise, just make sure the piston is close to TDC and you are good) I progress to #2, then #4, then finally to #3.

No need to remove any covers.
