Does anyone know off-hand the size of the hex socket for the inspection hole? I assume it is a hex. Also for the timing/CPS cover rivets, do you just start with a small size drill bit and keep increasing the bit size until the entire rivet is all drilled out? Anything to watch out for? Needless to say I want to check and if necessary adjust the static timing. Thanks. | ||

The hex is 3/8". The rivets are 5/32" Use a 5/32" bit and don't go to deep. If unsure put a stop on the drill bit, you only need to go about 1/4" deep to knock out the rivets. I tapped the holes on mine 10-32 and used Stainless button heads, some use sheet metal self tappers. Before buttoning back up blow out chips and rivet remains. | ||

Self tapping screws for timing cover, HD PN 2662W. Probably easier to just grab some from a hardware store unless you're at the dealer for something else. | ||

Do what you want but IMO hex head self tappers belong in HVAC duct work in the basement. | ||

Ditto jramsey. I used stainless button head Phillips screws and tapped the holes. Looks better, works better, too. | ||

The HD one's are thread cutting, and effectively thread the holes in the base plate. Worked well so far. I put anti seize on them and the ones securing the base to the cover, as one of the original ones was seized and I had to use an EZ out on it. | ||

As always, very much appreciate the input and the tips. | ||

I used the self tapping screws from HD, then installed regular button head hex screws from the hardware store. Didn't want to leave the self tapping in there permanently.. | ||

I tried the method described in the ECMSPY tuning guide and the timing seemed to be OK. I asked my wife to look through the hole while I turned the rear wheel while watching the 0 and 5 window on ECMSPY. Turning the rear wheel (even with the bike in 5th gear) wasn't as easy as I expected and did require a good bit of force. Is that normal or I didn't quite get it in the 5th gear? | ||

Spark plug removal will facilitate engine turnover process. | ||

kal, teh valve springs and compression can hinder movement. | ||

Al is right (big surprise there)  after the 10.5:1 upgrade, I physically couldn't turn Betty over with the rear wheel & 5th gear method without pulling the plugs. Even if you can turn it over without pulling them, it will be a lot easier to check timing after removing them because the engine turns over a little smoother instead of lurching away from TDC so suddenly on every revolution. | ||

Damn, I feel so stupid now... Note to self: Do not work on bike, car, kitchen faucet on Saturday (or any) morning after you had too much to drink the night before. |
