DRZ400E radiator neck size?

I'm looking at getting a mishimoto radiator cap with a temp guage in it to keep an eye on temperatures while riding, from what I can work out the small cap will fit 42mm necks but I can't find the information anywhere online on drz400e neck size

You might have to measure it yourself

It's looking that way

If you have a caliper it'll be easy, if not just about any hardware store will sell them.

I just measured my cap, 2003 drz e, cap is 42mm inside edge to inside edge. Post up a link of that cap you are looking at. I don’t think my vapor is correct, I might just need a sender.

That's interesting, I'm not sure on how measurements are designed to be taken however it does specify that it "does not fit KTM models" suggesting it is designed to fit jap bikes? I wish they could be a little more clear

Sorry for the delay, the inside of the neck on my radiator is 31mm and while I’m at it, neck depth is 16mm. Good luck, I’m going to just check my sender in some boiling water and verify the vapor is showing correct. Screw buying more stuff at this point.
