Thermo=Bob Installed

Yesterday's project was to install the Thermo-Bob and gauge face overlay.

I've been mechanic-ing for enuf years to be horrified when I read about the operation of the stock thermostat. Can't possibly be good for the engine and it makes me wonder what the Kawi engineers were thinking of. They should all be kicked in the butt for sending it out like that.

The decision to buy and install the Thermo-bob was a no-brainer - I had to have it, fast.

At first I tried with the instructions on the computer screen and the bike outside, but it was extremely awkward, so cheap-skate me finally broke down and printed the whole thing out - 20 pages worth, in color - and it made things much more simple when I could look back and forth on the spot.

The instructions are pretty much straightforward, but you do hafta pay attention. It took much longer than it should've because I double and triple checked each step before committing to it, then reviewed each step after it was done. That was all fine. Finished product worked 1st time and no leaks or anything else.

Then came the gauge face with the pretty numbers on it. Ahem. Yes, it is possible to pull the cluster without touching the fairing but I'm a big boy with big paws and it nearly drove me to frustration. Couldn't "quite" reach and it was a beast of a job.

Finally said "phooey" or some such while sweating over the 2nd screw and pulled the headlight fairing loose and tipped it forward. Folks, I'll tell ya - if you've got big hands, pull the bloody fairing. It made it Soooo much easier.

On fire-up when done it seemed to work OK. Today I took the bike to run errands and kept a close eye on that gauge. I really like having the numbers on the gauge - made the effort very worthwhile. It ran so close to 195º the whole time I was out that I couldn't tell when it was opening and closing.

This add-on (does it qualify as a farkle ??) is such an improvement I'd say it's not so much an option as a necessity, if you care about your engine. I'm very glad I installed it.

It's on my "to-do list"... I'm a mechanical imbecile though, so it will probably take me a half day to install. LOL

Good write up.

I'm mechanically disinclined, too, but I agree. With the help of Mark B4, we got it done, but printing out the instructions was a must. But, it worked like a charm and hasn't given me any trouble. And I like seeing the temp needle set right in the middle all cozy like.

Good deal. I feel better every time I look down and see that needle planted on 195º.

Quick question, have there been issues with NOT doing the Thermo-bob upgrade? I just can't figure out why they would make it this way if it was not good for the engine?

FWIW, it's my understanding that the KLR650 is one of the most reliable bikes on the road, so it can't be "too" bad. I also understand thermal shock and know it can't be doing it any good in the long term. Maybe the Thermo-bob will extend the longevity ??

Kinda like eating steak all your life, then wondering why you have a heart attack. Thermal shock the engine and eventually maybe have problems ?? Probably but hard to prove, I think.

To my eyes, it's kind of like the doohickey business. It's my understanding that it was a real problem on pre-08 bikes, but not so much so now, tho' it still isn't perfect. I really don't think my '11 needs a doohickey kit. Will I get one ?? Probably, just for the peace of mind it will give.

I went on my 1st real highway ride on mine today - about 65 miles south past Deming, NM to the Florida Mountains. The bike ran like a watch at 70 mph - big, noisy watch but it went fine. I glanced at temp gauge periodically and felt good seeing that needle planted on 195º. A bit later I got onto really bad gravel and rock roads that worked the bike pretty hard at low speed and saw the temp go to 210º for a while. That's fine......I'm not worried about thermal shock anymore. It helps that I like new toys, too. (I dumped it on that loose bull rock, too. Hurt my feelings, seeing that pretty fairing in the dirt)

Whatever you do, don't say that on the .net site! You'll be attacked, ridiculed and for final insult the Admin types will block YOU for one week for your blasphemy! Trust me, I speak from experience...

Just for shits and giggles.....have a look at your DOO one day and tell us what you see......I have done a few more than one or two ...lol. Yes the DOO itself isn't an issue any more....it's the frig'in spring! WTF??? Like I said, have a look and let us or me know what you see. Especially if you have a few miles on the bike already and have adjusted the DOO once. I'm curious.....and yes I too am banned.....lol. It is your bike after all and your choice to do any of these mods. There are many bikes out there that are happily riding down the road without even hearing about either the DOO or a BOB.

I will bet that after a few tens of thousands of miles and after one adjustment done....you will find a very loose or dangling spring......just saying. Anyone who buys a KLR and doesn't at least check this issue is fooling themselves imho.

Yes all you need to do is get a shorter spring and the problem is solved but you do need to do something.

Let the storm begin........lol......
