I had the opportunity to remove KLX's body work today so I could get at the carb' and measure it (There was a nice external oil line up the back of the engine, Greg)
Here goes the carb' venturi measures 42mm, from the top of the venturi bore to the top of the carb is 58mm (the throtle cable mounts are a little higher but there lower mounting holes to get round this if needed).
From the bottom of the venturi bore to the bottom of the float bowl is 75mm.

The overall length of the carb body is 53mm but to this you must add the bellmouth,3 sizes available (I don't know which mine is but it is 34.5mm),and the stub,mine sticks out 15mm from the carb body and is threaded into it, this can be changed to suit. (total length of my carb' is 102.5mm).

The most difficult one, I think, is that the float bowl under hangs the inlet by about 10mm, two things you could do here, if it's a problem, get a longer stub or spacer the inlet rubber away from the head.

That's all for now.

Finally got inside all that thermoplastic, eh? Just kidding Tongue

I need to measure my carb (darn, I haven't done that yet?) and compare to your measures. That sounds like my next measuring project for this weekend.

I only glanced at my bike a couple times, and never rode it either. I'll get on it soon.

Everything looks OK to go ahead with fitting the FCR41, the closest part is the throttle cable anchorage clearance with the cylinder head cover, if it does touch it would be easy to modify or unbolt and make a new one. I expanded the pic to roughly life size and it looks like it is about 1/8th clear and You can grind 1/4 off the anchorage, If it was My 'bike I'd do it. Sorry this is late I wasn't on line last night.
