Let us know what you think and any difference
I'll try to keep this short. My professional opinion, this is my 201st bike and on cars I'm on #53,54, 55, 56. Wrenched every one of them.
Road the bike this cold morning as I was going to work and as we know, on cold mornings the bike's not going to get to optimum running temp. I forgot something, turned around and went back home. Left the bike idling in the drive while I went in the garage to get what I needed. Now the bike's temp gauge is right close to the middle... right at optimum temp. I take off on the bike and it feels good. I could actually feel a difference from the stock set-up. I'm happy.
At first when I pulled out, it felt as if the mod was useless, cause I thought the bike, stock, ran quite well and smooth. So I was thinking, not much difference with this 22c mod.
To sum up TWO points, the KLR runs better with the mod (I did, 1 shim, 7/64 hole, and 1.75 turns out) WHEN it's up to temp. Which makes me highly recommend the Thermo-Bob. Mine should be here today or tomorrow.
Effectiveness vs One's Abilities:
My bike ran well stock without the 22c mod.
If you're handy, do the mod.
If you're not handy and you can get it done for a beer or so, do it.
If you don't have time nor handy friends and you have to spend more than $20 to do this, I wouldn't, UNLESS you're doing it to compensate for power adders.
