valve adjustment

Basically he is saying drive it like a granny for the first 500 miles, but accelerate and decelerate frequently in gear, keep rpm under 4000 like the book says, but don't be afraid to use 1/2 to 3/4 throttle.
A good thing is to go up a big hill, and go back down the hill in gear, using the engine as the brake.
Definately do not overheat the motor. Production engines are built a little tight, and you don't want to scuff or sieze the motor. They will also typically run a little hot when new. Like anything, moderation is the key.

Yeah, it's more fun to get into disputes on subjects you don't know much
about.

So.. Do I understand you correctly? In the first few miles one should
accelerate and decelerate hard; after that, for 500 miles or so, one should
take it easy but not lug the engine. Also I've always been confused by what
is meant by varying engines speed. Does that mean change revs every 100
yards or every 1/4 mile or what ? Sorry to drag you into this but you have
much expertise and I'm curious as to what you think.

Around.. 1,500 miles mine were tight, but in spec range still.
Numbers somewhere in garage, but nothing drastic.

At 1800 none om mine needed adjustment still in spec just starting to
go to the tight side of the spec.

..............Let me guess: the KLR is of the "designed for longevity" type.
In any case, I pretty much paralleled these guidelines (exhaustive details
penned in an earlier post) on my second KLR after breaking in my first one
like a wuss as per KHI. I gotta say the newer one has more spunk and snap
seat of the pants power than the first did.
Incidentally, I finally got around to doing a valve clearance
check/adjust. Last one was around 10-15,000 miles, this one was done at
33,000 miles. Last time I left clearances at the outside of spec........008
intake and .010 exhaust. I found these at .007 and .008 intake, and .009
exhaust. Hmmmm. Hardly any change after around 20,000 miles. Go figure. If I
recall correctly, the last adjustment required very little change, and it
was the first since new. Go double figure.

The first ten minutes of operation is the time most break in occurs. What I mean buy hard accel-decel is a good twist of the wrist and back off but not full throttle - use it don't abuse it. Keep engine speeds down - in the case of the KLR the factory recommended 4,000 RPM until 500 miles is good but brief times above 4,000 RPM shouldn't hurt. Varying engines speed is not maintaining a constant no load speed. In the real world in traffic it is not always possible. It is not necessary to do this 100% just as much as possible. My KLR did not feel fully broken in until I had over 5,000 miles on it. I never babied it but rarely go over 6,500 RPM except for the occasional overzealous first to second gear shift.

The other side of the coin with this low-RPM approach, however, is
that it can lead to forming a ridge around the cylinder at TDC. A
piston will actually top out at slightly different locations in the
bore depending on RPM because the connecting rod (amongst other parts)
will actually stretch a bit at higher RPMs. If your engine doesn't see
higher RPMs during break-in the piston will never reach the topmost
parts of the bore, leaving that portion of the bore relatively
un-worn. This causes a ridge, or step, to eventually form.
The end result is that your bike will burn a bit of oil and not
produce the most power possible when running in the higher RPM ranges.
This is, IMHO, why many KLRs will burn a little oil when running on
the highway at higher speeds. (Of course, the large ring seal area
because of the large bore diameter also plays a significant part in
oil consumption.)

Blake,
Another side of the 'ridge' you mentioned: IF it has formed in an engine that's NEVER been
really revved... when you (or the next owner) DO rev it, as the rod lengthens and the top
ring contacts the ridge, which WILL happen just prior to TDC, somethings GONNA give -
probably the ring-land in the piston, which'll make a quite expensive sound as it "grinds"
to a halt.

free panniers and a riding suit for list members
Posted: Thu Apr 13, 2017 12:17 pm

Things need to go to make room. A pair of aluminum panniers is on Craigs list for $50 but are free to anybody on this list. They were on the Tardis originaly. Also I have a riding suit listed for $100 that is free to someone on this list that it fits. You must come to get them because Im not going to package them up. Located in Canton CT. Call 860-965-7501 when you plan to head out in case they are gone. In two weeks the go in the trash/recycling if they are here and sooner if someone comes wfrom the Craigslist postings

It's that time. Does anyone have a step by step procedure on how to do this? What solvent they use to clean etc? Any tips, Maybe from previous email?
