John,
My reply wasn't a jab at you (although you seem to have taken it that way). I was just stating my experience.
Marc

I stand corrected. Your (presumably) expensive car apparently does not have a thermostat. How could I have known.

Well my personal experience with my more my Corvette (406 long rod small block with no thermostat-has a restrictor) has shown from tear-downs to have no appreciable wear without a thermostat and by-pass.
Like I said-to each his own

Thermo-Bob minimizes engine coolant temperature fluctuations which minimizes engine wear also kinder to your oil. That s why your expensive car has the equivalent of t-bob. The KLR cooling system design was probably borrowed from an offroad bike which is ok for most riders who will probably never hit 20k miles on their klr650.
Not shilling for wattman but I believe his engineering is sound.

Well too bad about the issues (how many miles on your 08?) and congrats on the 685 (should be nice).
I would follow their break in.
Side note- I babied my 08 (no 685) during break-in and changed oil/filter every 500 miles until their was no metal in the filter when opened up. (I always do this on every motor) and switched to a 16 front sprocket to keep rpms under 5000 (I noticed oil use when over 5K) I hope to 685 mine when needed. So far no oil usage, but I only have 10K on the motor.
Not a big fan of the Thermo-bob. Don't see the need for it and it's another point of failure. To each his own.
I think the PVC mod is valid and have thought of doing it myself this winter, but want to get the Benz turbo valve instead of a regular valve.
Good luck.
Don't forget to give us details.
Marc

Hi all,
Long story short: I had the unfortunate opportunity to disassemble the engine on my '08 KLR (KACR sheared a gash in the valve cover and then exploded into about 6 pieces). While it was open, I decided to go ahead and have the Schnitz 685 kit installed, mostly in the hopes of stemming the rather alarming rate of oil evaporation I had been experiencing (and which likely contributed to the unfortunate opportunity).
Anyhoo... the fixes and mods should be complete any day now, and I would like to ask the group for the consensus on a few topics:
1) Break-in. The Schnitz documentation (
http://www.schnitzracing.com/manuals/KLR%20685cc%20Kit-Instructions.doc) recommends a regimen of phased break-in with lots of engine breaking etc. Or do folks favor the "ride it like you stole it" method nowadays?
2) Schnitz recommends the thermo-bob mod. I have followed the debate here and elsewhere on the relative merits of the mod, but I guess what I am wondering here is whether Schnitz's forged piston (as opposed to whatever the OEM piston is) changes the math at all.
3) Schnitz also recommends the PCV valve mod. Not even sure what this one is, though I vaguely recall reading about it. Opinions?
Thanks,
John
