The KACR was available on the KLX250/300 models even before the electric starter came along. I'm betting that the electric starter will do its job without the KACR.

 

What???? If it can start without it, that will be the next mod...... There must have be a hundred times that dam ACR stalled my engine, right at the cusp of clearing that big rock, topping the gully, and I ended up falling on my assos.
Keep me posted!

 

You've just made my day. Now I can stop blaming my lame skillset and lay the blame squarely where it belongs - that stinkin' ACR.

Now that I think about it, my 400EXC didn't have an ACR and it had a smaller battery, a smaller starter and a bigger engine. Started real easy-like.

I'm guessing that was introduced for the kicker and is totally unecessary. But, we won't know for sure until the OP tells us.

 

Q: Does the 1997 or later Cylinder/piston fit the 1995 model?

 

There is a point going back with the 250 where the cases won't accept the later cylinder if I remember correctly. Or was it just the 300 cylinder? The case opening where the cylinder fender skirts drop down aren't big enough for the 300 cylinder for sure, and maybe even the later 250 cylinder. Something to clarify for sure.

 

So has anyone removed the ACR? I'm curious if the bike stars without it.

 

There are a couple of guys on here with aftermarket cams that don't have the KACR. They never reported any starting issues. There are tons of bikes with single and multi cylinders and no ACR, they all start fine.

Kawasaki would have to be pretty dumb to install a starter that was so weak it needed the ACR to turn the bike over...

IMO
