opinions needed - not a good noise

Evenin guys,
A17 with 3K miles, bought it with 1K on it. Stock except for air
screw backed out. Over the last 1K miles or so I started getting a
knocking/heaving pinging maybe scraping noise when the engine gets
up to about operating temp (2/3 + on guage) while accelerating
moderately and up. Doesn't do it when motor is less than 1/4 on
guage or so. Haven't got around to taking it to a Kaw dealer to
check it out yet, as it's still under warranty.
Any suggestions/opinions ?

2/3 and UP?? Can you be more specific? If your saying that
your "normal" operating temp is 2/3+ of the dials travel, that's too
hot. Even 2/3 is too hot. Even half of the gauge, or just a hair
past half, is where mine will be at while riding very slowly in the
woods and no air flowing through the radiator, or on the road with an
outside temp of 100 degrees plus. My "normal" temp reading is about
2 needles width into the red. At long stops or in town, my needle
will go to about 4 needles width, but still below half. At just
above half, (needle straight up and down as you are looking at it) my
fan kicks on for a few seconds and takes the needle down to below
half immediately. Are you sure you turned the fuel mix screw the
right way? Are you sure that your fan is working? Radiator or
screen clogged?
Most other bikes that I have ridden, that are stock or close to it,
run a little hotter than mine, but not nearly as hot as you are
describing yours does.

Actualy, just over half is where my fan kicks in and is as hot as it
gets. My mistake. Damn, I gotta go the rest of the year now without
making another

Ok, well, then that's all working well. Now how about more info on
this noise. Is it a low end sounding knock, that you can hear only 1
or 2 times when blipping the throttle off idle? And can you hear
that same noise for a second or two, while taking off from a stop,
sorta like chugging the motor a bit? If so, that's normal.

Let's see if I can explain it a little better.
Temp guage at half way, 3rd gear, RMP's as 2500-3000, cruising along
nicely and open throttle to half way so its pulling a bit and theres
the knock. Will keep doing it till I let off.
Doesn't do it if engine temp is below 1/4 on guage.

Sounds like detonation. Let me guess, you are close to sea level and using
regular gas. If that is the case, try premium fuel, or shift down and get
the RPM up before cranking on the throttle.

The KLR650 calls for minimum 91 OCTANE. At least for the A16.
Allan probably hit it, I hope.
Happy New Year, Hu Rah!

I wonder what change could have possibly been made to the engine to require
91 octane in an A16 when according the manual the A15 only requires 87
octane (pages 28 & 29). Unless you are reading the RON rating which is 91
but the common rating shown throughout the country at the pump is the
RON+MON/2 which the manual states 87 octane is all that's normally needed.

That was my first thought but I only use premium. I have tried
several different brands with no success.

To the best of my knowledge, in the Motorcycle industry FMF is the only
outfit playing with, or making any claims for improved performance for this design.
From where I sit the problem is when dyno tested by the dirt bike magazines
these FMF designs have not shown any advantage.
Basically, back in '99 FMF came up with a what they called the 'Power Bomb'
header. Basically it had a small mini-muffler in the head pipe whose advertised
purpose was reduction of noise. Never really worked to reduce noise levels
but started the rumor that 4-stroke headers could be tuned like a 2-stroke. To
date, while they remain committed to the design FMF has yet to come up any
combination of sizes and lengths that really work.
