    Yeah............ could be overkill :lol3

    I thought he was trying to actually measure max-wattage output of new narrower stator vs. OEM..

    You could also "borrow" the column oil heater while the other half is not watching and use the element in it to act as a load for testing, would suggest you reassemble and return it to the lounge room before anyone notices it missing though

    The planets aligned today so I started putting Stephanie's stator back in the bike.

    Warning! This rotor has a razor blade sharp surface which gets the tip of your finger if you try to wipe the muck out of the rotor and your finger touches the surface.

    But the stator went in well. I managed to pull the old wiring out of the rubber bung which seals the case, and put the new cables through the original holes so the join I made to the original wire is up near the connector itself, meaning most of the wire is now a larger gauge, and newer.

    The holes in the bung are angled, so if you take that into account, it makes it easier to put the new cables in.

    The Haynes manual said the screws needed to be tightened in this order.

    excellent...
    does anybody know why the "pocket" in the cover between #1 and #6 in the diagram is there?

    Looks like a vent into the side cover to me. Perhaps to help equalize crankcase pressure?

    Could be... are there vent passages in/out of that pocket on the cover side?

    I'm sure it was done with purpose, but I just can't figure out what the purpose is............. :huh

    I think I can get a stack of dimes in there ....... :lol3

    I suggest you collect those dimes. You're sure to need them eventually.

    Yes ... apparently about 9000 of them :cry

    I looked and could not find any dimes!

    It might just be a blind mill hole to access some other function further in the crank case.

    I put my "electrosport" in today. The connectors plugged right in and the grommet fit fine...0ver 40F in the garage.

    Success the bike started right up and my cheapie dash mounted 3 color LED voltage monitor turned from red to green. good enough for me

    If is warm tomorrow I'll dress up and cable tied the harness back in place... and be ready to hit the road when the salt and sand are off the roads....maybe in march!

    I managed to finish the job on Stephanie's bike today and it started right up, and everything looks good on it too.

    We're expecting 10-15 cm of snow tomorrow so it's doubtful we'll be riding anytime soon, but we're now ready when the weather is.

    Thanks ... just seems odd that they would cast a matching feature in the side cover (well ... odd to ME) :1drink
    Maybe it serves some purpose for the engine in some other application.....

    It has served it's purpose, it has you intrigued, those engineers are so smart and intuitive :wink:

    a few other attributes commonly apply to engineers that ride motorcycles ... but listing them might get me banned .......... :lol3

    I kinda spaced out (Yeah big shock :lol3 ) on one thing I meant to follow...

    Back on page 31 of this thread...

    1) is some talk of a Buell flywheel modification that allows oil-spray cooling of the stator. Presumably there is some supply passage in the crankshaft that makes this possible ... for those of you that have pulled your flywheel on the twins ... have you noticed if perhaps any such feature exists on the BMW crankshaft?

    2) the guy drilled 6 small holes around the perimeter of his flywheel to aid air circulation ... has anyone heard follow up on this? :wink:

    I'm just a simple country doctor Jim.

    Not tryin' to discount your logic so no need to get in my grille. :D

    I don't think many have had up close and personal time with their cranks. Not to that extent anyway. Drill the crank? Too scary for me. Not without the engineering docs that say go for it. It's like when you hot rod a car engine. The tranny blows, you beef up the tranny and the driveshaft blows, then you........ you get it.

    Drilling air holes sounds good if you have the time and shop to do it in. Balancing would be an issue since it spins at crank speed. I'd consider that if it could be balanced cheap enough. And the odd prayer that it doesn't grenade.

    If I had more money and less time, I'd do the $900 swapout. Since I have more time and less money, I'll buy the $100 stators as necessary. Even if you get 10K kms out of a stator, you're 90K kms into it before you break even. Adjusted for inflation of course. Add a voltmeter to keep an eye out for impending doom.

    I dunno. I'd rather ride.

    In a missile free area! :lol3 (loved that idea!)

    Me no drill crankshaft, not even for many bottles firewater ... :freaky

    The way it apparently works on the Buell is that there is a "concealed" oil port on the tapered part of the end of the crankshaft and all that is required is to drill an angled hole in the flywheel (at precise alignment & diameter, etc) so that it meters a small amount of oil into the interior cavity of the flywheel cooling the stator ... you send the guy your flywheel he mods it and sends it back and you are supposed to be good to go ... no dinking with the crank. Since the metal being removed is so close to centerline of flywheel and not much material maybe balance is not affected, or maybe the Buell guy re-balances ...

    So question I that I was trying to ask but didn't phrase real well was:

    Q: For any twin owners that have had the flywheel off the end of the crank, have you SEEN an existing oil hole along the tapered section where the flywheel mounts? I really doubt it exists on our bikes, but if it did ... that would be way cool............. for the stator... :lol3 and a cheap fix for us....

    I've got the voltage monitor ... and hope stator would fail slowly, giving me time to plan repairs ... but am planning long trip for this summer and don't want to lug along a spare stator nor get caught 100 miles from civilization with dead battery ... just kinda annoying... for trail riding the RAT may not be a match for my skills... and pac-man may not like the terrain... I may be back to the bike-generator...... :lol3

    I'll see if I can at least get us each a rocket! :d

    Well... it's 5PM EST ....... :1drink
