Any one using a Mishimoto radiator temp cap

I'm having the same problem as most with an EFI bike (12’ KX450)....gas in the oil after the temp drops below 20F.fficeffice" /><O></O>

I purchased Mishimoto radiator temp cap and ran it for the first time Saturday to better see what the coolant temp runs at. I ended up blocking the front of 1 radiator completely and the other ¾. The temp on the cap was reading 150 at the end of the day. The problem was on Sunday when doing maintenance on the bike I pulled the cap off and noticed that I was missing around ¼ of my coolant (below the fins). With the stock/normal cap the bike has never been low on coolant.<O></O>

Does anybody have experience with this cap or if this is normal? Any and all input is welcome.<O></O>

The problem could be in the spring of the mishimoto cap, having a lower temp sping so it opens up earlier thus loosing coolant.Are you running a rad overflow?I know my bike liked to spit out coolant and by the end of the ride, it was down a few ML,I did the old "turkey baster" mod and haven't lost a drop since.

ya they're garbage.

I'm losing a little coolant at times. I haven't heard of the "turkey baster" fix. how does it work.

Its because its only a 1.3 bar cap. The KTMs run a 1.8 bar. I run a Mylers 1.6 bar cap. The higher the pressure the higher the boiling point. When i was running my stock 1.1 on the CR it would lose fluid all the time. 1.8 would be better ! The gauge would be cool to have though LOL

the way it clamps on is nfg too. have a good look and you can see.

No I'm not running a overflow...never had a reason to run one before.

KX450 comes with a 1.3 and that is all I have ever used on (2) 2009 and the new 2012 without losing coolant. I have a Kawasaki 1.8 but have never had to use it.

I agree the clamping on this thing sux. It would be great if the cap would hold the correct pressure for a quick look at the coolant temp. Time to send back and get my $65 back.
