M10 madness

Reply from: Dean H.
Date: 11 May, 14:58
I need two M10x1.25 flange nuts. I found those for something like $2.50 a
pop, so that's less than driving around to a few hardware stores and they
won't have them anyway. The BRP handlebar clamps which I curse came with JIS
bolts and nylok nuts. The nylock nuts don't allow room for the socket wrench
to hold them as they sink into the recess of the Gas Gas triple clamp.
Flange nuts like the stock nuts fit fine. But the stock nuts are M10x1.5
threads of course.

And I'd love to replace the JIS M10x1.25x70mm bolts with some 50mm ones just
because all that extra thread is ugly weight which serves no purpose. But so
far I can only find full 25 count boxes of JIS M10x1.25x50. The JIS M10
bolts have a 14mmhead which the BRP clamps require. Maybe I should just cut
the BRP bolts.

Excuses, excuses...

Barbara Walters was in town signing books at the independant bookstore in
town. I waited an hour and a half to get one signed for mom's Mother's Day
gift. I hope she didn't already read it. Barbara looks like she weighs about
12 pounds.I saw the line and said no way. Then I went to the hardware store
for white lithium grease. I changed my mind and when I went to get in line I
got the last two books (that weren't prepaid/reserved). That white lithium
grease is good stuff. Couldn't find my old can. Ten bucks. Ouch.

All that pussyfooting around in the motogroove van without the throttle
pinned got me the worst gas mileage I ever recorded from that van - 14.3
mpg. I'm going to drive "normally" on this next tank and do the math again.
Stay tuned.

Get these ones :->

Here are some, but no JIS rating apparently:

Here's a [cross-referenced] KTM axle adjustment bolt that might
work (number "40" on the illustration):

In fact, there are probably tons of [durt-bike] cross-reference
options if you have the time to look. So if you were already pondering
an order to Bike Bandit, Cyle-Parts.com or a manufacturer, this may be
a good time to combine an order?

Of course you could always just cut the bolts ;-p

Titanium would be sweet but that flange head won't fly. Only need the flange
on the nut. The bolt needs the 14mm hex head, which is what the JIS is all
about.

Hmmmm... SCREW M10X1,25X50 WS=10
but again, who knows what size the hex head is?

I'm guessing I might have better luck looking at jap crap since JIS is
Japanese Industrial Standard. Not a bid idea.

Or leave 'em long...

Just so you know, M10x1.25 ("fine" thread) is just about the most
common metric fastener used, but you won't find it in a hardware
store. M10x1.5 (std thread) is in just about all of them. M10x1.25
is the size used on all japanese car exhausts. You need to find a
specialty metric fastener store - they're worth their weight in diesel
fuel.

Well, normal driving got me 15.416 MPG over 830 miles of mixed driving.
I guess the moral of the story is don't burble around with a feather foot.
Stab it and get the motor up in the efficient range quickly, then go easy
and resist the urge to rev it to the moon.
There was four hours of highway mixed in there but not at efficient speeds
( between 70 and 80 mostly in a vehicle shaped like a brick wall).

That hypermiler stuff that Mike W posted was interesting and frightening at
the same time. That pulse and glide thing or whatever they called it is as
unsafe as any other unpredictable driving behavior. Don't confuse the
drivers around you is one of the first rules I taught my daughter. Not to
mention pissing them off.

Anyway, off to step on the pedal now.
Have a great holiday weekend everybody.
Hopefully Sean and I are going to ruin a few fishes day.

glad I'm not live bait*

*some may disagree with that ;-)

Moderate acceleration is the key, because a gas engine gets more
efficient (at turning gas into work) the higher you load it, up to
about 75%-80% of rated load.

Working against that is you want to get into high gear as soon as
possible, which is why just stomping on it doesn't work best.

That van have a lock-up converter?

Putting in a tach so you can see how much pedal you can give it before
the converter unlocks can give you a nice mileage boost, especially if
you're traversing hilly areas.

Keeping the converter locked gives a nice boost in mileage, keeps the
engine revs down (good) and keeps the converter from wasting energy
through slipping (also good).

Probably the best accel profile is to give it gas enough to accel
briskly, get up to cruising speed, then let off just enough to get the
converter to lock up, then fine-tune the pedal to your cruise speed.
Driving this way won't give a big boost on the freeway (unless you're
unlocking the converter a lot) but it can make a surprising difference
around town.
