Dropped in the, "Thermo Bob" kit

In an efford to "fix" my '09 BEFORE it becomes a problem, my goal on THIS KLR was to fix the weak links before I broke 200 miles.
so far I've....
1. Installed the Doo fix, (Key-rist the motor had 100 miles and there was NO spring tension on the lever. The spring was rattling @)!
2. Did the .22 fix
3. Now to TRY to keep my oil where it belongs......
I've installed the "Thermo-Bob" thremostat kit.
The idea being that the cylinder "flexes" whilist heating and cooling as the OEM thermostat opens and closes. The idea also being that the thermo is too cool, (165??).
The kit contains a nice almn. housing well made, looks trick! (the pic on line makes it look like plastic, but it's a nice unit), with a by-pass fitting. It also has a fitting for the lower hose for the by-pass system, so the engine always has a coolant flowing.
Drop the coolant, remove the OEM themo, (the kit has a "O" ring seal).
He has nice instruction, (with great pics!), on how to install it.
Over all it took maybe an hour including taking all the body parts off, watching a U tube vidoe on an older KLR install, looking at the instructions.
I was concerned the motor would take longer to come to operating temp cuz it has a flow, but it came to temp the normal amount of time, (I use it to commute every day, so I know how many streets to the temp comes up).
The temp is running a tad higher, but no much (I think he has a 185 thermo in it).
The temp needle stayed same place through traffic, idling for a while.
Over all I like the kit, like the look.....
No to see if I use oil........

If it ain't broke, give me time, I can break anything.

Joe,

I put a thermo-bob in my 09 and I like the way it works. Its a tight squeeze in thes Gen2 bikes though. I currenty have 3500 miles on the bike and instead of burning oil like I have read others do, mine tends to sip. Point being, it still uses oil but seems like less than others. We shall see how it is at higher miles, only time will tell.

My 08 seems to use less oil than some too and I do have the TB. I don't know if it is due to that, but I like seeing the needle right in the middle and knowing the engine is happy.

Congrats, dude. You shelled out money for a worthwhile farkle. IMHO.

It annouys me to no end that I HAD to do this to a new bike!
Comming from 42 yeas of off road racing, if a bike had a weak spot, the following year it was addressed, but for some reason, Kawi figures breaking the Doo is Ok, (I guess cuz the KLR is bulletproof, they'd last forever and they wouldn't sell any new ones?).
Well see how this works out in the long miles.
I usually dump my oil ever 1000, or 1500 miles and my love affair for bikes usually last one riding season (if that), so if I dump less than 2 1/2 quarts, the BMW 1200 may- no WILL replace this bike, it'll be the LAST Kawi I buy, (if they can't fix this KLR, after what 20-25 years? what are they doing to the other line ups?

Fix it today, or push it home tomorrow!

I completely agree. Of all the bikes out there, Kawasaki is at the bottom of my list as far as what I'd purchase again..

Even BMW fixed the surging issue that they wouldn't admit to actually being an issue.
