Hey Shirley, drinks for everyone,

Got the new tanks on, with some swear words. Dash does not want to fir, I'll have to trim one of the two I have down a little. Got the saddlebag lid back, amazing what some repairs to crack fiberglass and new paint have done for it. She fired right up when some fuel was fed to her, had her running about 5 minutes when I saw A bright blue-white flashing coming from just next to the rear cylinder. One of the wires coming from the battery had lost its insulation and was grounding out. Quickly shut down and pulled the wire away from the piece of metal it was trying to ground itself to and the (Black) wire fell apart in my hand. At this rate, Louise will be ready to ride by the end of the season. I think I need another drink.

more drinks please.. Replacing the burned up wire...easy. Started bike up, all electrics working good. was afraid the ground might have burned out alternatpr.. but no problem there either. Ran the bike, let her warm up, set the idle speed/mixture and reinstalled air cleaner cover. Shut down for a break, went and got a mug of iced tea, come back to garage and there is a puddle of gas under the bike. Apparently the float stuck in the carb. Just took a tap with a screwdriver handle on the bowl to free it up and stop the overflow, ( which required taking the air cleaner off to get enough access)..



Ah, minor teething problems. You'll get her straightned out in a bit.
I, OTOH, have to pull the oil pump and cam chest apart on Mistress Pearl. Didn't touch 'em during the overhaul, but I'm loosing oil pressure somewhere and feel an inspection is warranted. Glad I bought an evo to ride when she's down.


Shovelheads don't have oil pressure, any pressure beyond what it takes to turn off the oil light is coincedental (that pressure is provided by the check valve. The pressure relief valve is a safety so the (coincidental) pressure does not go too high when cold. The only thing that requires any "pressure" (besides the oil light) is Hydraulic lifters, any pressure is enough for them (if your motor has them).

Shovelheads are splash lubed, the rocker shafts only look like they are pressure lubed, if they had actual pressure you would need waders on to ride it and it would not be called a shovelhead it would be called a sprinklerhead.

Take off the gauge and smash it, reconnect the light. You can't watch the gauge when riding and you will notice a light on far quicker than a gauge reading zero. Use 60W oil in summer. Get a Baisley oil pump overdrive gearset and an oil cooler if you are really concerned. I know a gauge is "cooler" (and way cheaper) than that knobby cooler, but those are the facts.


Rick, everybody keeps telling me this, *but* the bike has held the same pressure for 6 years or about 60k miles and now it's changed....suddenly.
After I ride the thing about 10 miles the lifters start clattering. I know for a fact that that ain't normal.
It's got a cooler, and until the tee fitting broke a couple of years ago(20 min before myself and 4 other people were to leave for Roger's party)it had the light hooked up.
The low pressure wouldn't concern me(hell, you don't hear me bitching about my evo that carries about 15 when it heats up)if it hadn't suddenly changed, or the lifters weren't clattering.
It's got an S&S pump on it already, and I've also made inquiries of my indy dealer about the Baisley gears(not sure if they make a set to fit the S&S pump).
My gut tells me it's some kind of trash in the oil pump, but life has kept me from tearing her apart yet to see. She's sitting under a cover in the shop with a battery tender hooked up awaiting her owner to get time to pay more attention to her. At least there's no puddle under her at this time, and the evo runs.


Good on ya for coolin the beast.
But if the lifters are going flat the clue bus has arrived!

The overdrive gears are not pump specific, one goes on the crank one on the pump drive shaft. But don't use the overdrive gears to bandaid another problem.
I am concerned because if trash is going through the pump it is being shed off something else. And if something is shedding trash, that is usually another stop by the clue bus. (and not a good one)


I just did the top end on it, and I'm thinking some gasket trash may have found it's way into the cases when I scraped the base gaskets off the cases. At least I'm hoping that's what I find. Had a tiny bit of gasket-like trash in the lifter screen at the first oil change after the rebuild, but none in the 2 other changes during the break-in.
Thing still starts and runs strong, makes no funny noises and has never had *no* oil pressure(just low)so I'm thinking I've caught it in time.
After I get back from our little jaunt around the country I plan on tearing into her. I'm actually thinking about coming home a couple days early so I'll have a vacation day to tear her apart.
At least she still looks good sitting in the corner<g>.
