Choke needed to start hot or cold

New forum member with new to me '03 650. Know little about bike's past.

Always starts so I shouldn't complain.

De smogged CA model, idle mix at 2-1/2 turns out.
Stock clean air filter.
Just added some Seafoam but haven't ridden any miles yet.
New plug.
Stock muffler.

Choke on full, hit start, slowly move choke towards off and she starts with very little throttle but some required. Too much throttle and no go.
Does not "leap" to life but starts firing and revs build rather slowly.
Idles well and runs fine.

Nature of the beast or problem?

Don, I'd ride it a couple tankfuls to see if the carb clears out before jumping into it..
It's not a problem, but I know some of them do require a bit of choke when starting. My 02' starts without choke once warmed, but Double A's 98' requires a bit of choke when warmed, with both riding the same amount of time during the day.

On the other hand, he gets a bit better fuel mileage than I do, too..

I will ride the pee out of it soon.

I've got my sidecar subfame all ready, in fact it's on my living room floor right now (I am single)
Going to ride the Taos area for week on my road bike and will get 'er done upon my return.

Single life isn't all bad..
I store any bike that'll fit in the door in my back bedroom, and I've been known to wash cosmoline off of old military rifles in my dishwasher.

Try to get away with that when you're married..

Up early and setup the sidecar. Too hot to go out on the road now but after just a few laps around my neighborhood (10 miles maybe), I've had to lower the idle speed twice. Perhaps the Seafoam
is working its magic?

Seafoam has pretty much replaced Techron as my cleanup stuff. Even fixed a couple of gummed auto trannys with it.

On advice from another KLR nut I decided to check valve clearances to see if that's contributing to my hard start. The envelope please:

Lt ex=.06mm
Rt ex=a .04mm would not go.
Lt in=.13mm
Rt in=.11mm

Ah ha!

Ah ha!

Inlet valves- .10-.20 mm
Exhaust Valves- .15-.25mm

Remember that loose valves are happy valves. Some people keep their's adjusted in the upper third and there have been some well documented bikes that get much better fuel economy this way.

I was able to set the int by doing the shim shuffle but I need a 230 and a 235. Hopefully my stealer will have them.

I measured all the shims, one had no marks and the 255's measured 250 and the 265 measured 260.

My dealer didn't have an idea on what size shim the KLR used, I ended up ordering what I needed from www.arrowheadmotorsports.com Got them in about four days.

2008 DL650 VStrom Yellow and Black
Previous ride was a 2007 KLR Black/Silver, I miss it..
Looking to get back into KLR's sometime soon.
