The would be nice if they built that for Mikuni's as well.

 

Will it fit the CVK? That would be so nice to just reach down and change while climbing up those mountain roads/trails.

 

Yes, it fits the CVK on the KLX250S.
Nice piece of equipment, there's goes another small ding to my credit card dammit.

 

Post some pics when you get if fitted if you don't mind.

 

Sorry guys I was going to post this mod and forgot about it.

I have one from Dean at R&D, its called the flex jet. I am using it on the FCR, and whoever is running one knows that there is almost zero clearance between the fuel bowl and the starter.

I had to mod the bottom of the fuel bowl just a little so there was room for the flexable shaft to come out, but the screw works flawlessly. Right now the **** is just hanging there(which doesn't seem to matter) but I need so make a small bracket to mount it to.

This is a must for an FCR owner. I'll see if I can get a couple pics up in a little.

 

Tried to order one, but the website doesn't recognize my military mailing address.....damn! Anyone willing to help a brother KLX'er out and get one and mail it to me?

 

Oh you bet!
I'll post a photo of the fuel screw up right away.................you don't think that I'll have any difficulty installing it do you? I mean it does clearly state that it works on the KLX with a CVK and all.

 

Designed for Keihin carbs. That's CVK and flatslide.

 

You mean for the idle speed? My (Bill Blue) Mikuni has one.

Also opted for the t-handle idle mixture screw. Very much worth it.
