starting problems

[Duane Ausherman]

It really sounds like a lean mixture.

Stop messing around, do the simple test suggested by Ken. Remove the plugs and drip in a few drops of fuel. Replace the plug and don't open the throttle very much. If it fires a few times and quits, then that is a strong indication that it is running lean. Repeat with a bit more fuel. Then it should run a bit longer and probably quit. However, you may have it warmed up just enough to be able to keep it running.

What result do you get with measuring compression? Where did you see the timing mark on the flywheel?

This stuff is just plain logical and if one follows the trail, all will fall into place.

Back in about 1968 I needed to hear an engine run. It had some mixture problems and I tried the usual stuff. I ended up removing the air intake tube and squirting fuel into the intake from a squirt bottle. It worked and I was able to ride it a couple of blocks with my right hand on the throttle and my left holding the squirt bottle to allow in a bit of fuel. I had to tape up my left pant leg to keep it from getting sucked into the intake.

I don't recommend that procedure.

SteveD, I've got to have a can of Start Ya Bastard. Not to start my bike, to put on the fireplace mantle. I love Oz advertising.

I didn't see where anyone mentioned that the fuel enrichners only work with the throttles closed. Don't give it any gas until it hits!

Right Dan! both my airheads require you to keep your hands off the throttle when starting them

Yeah, I think that's all slide carbs isn't it, not just CV's? Except those with accelerator pumps, of course.

I'd send you some, but it might cause the plane to disappear! I doubt it'd be allowed in the post.

I think Malaysia Air says they will take it for you.

I have a 1992 R100RT with 30k. It is just about impossible to start when it is cold. I mean 45F or below. Where should I look for the cause of this problem?

Something easy to check is the jet located in the fuel bowl. Put some fuel in the bowl and use a compressor to blow down the passage in the bowl. You should see bubbles.....It one or both are blocked, your bike will be hard to start when cold.
