Had this same issue with mine. Juat spent about 6 hours pressure testing, tightening hose clamps and doing a leak down. Finally got it to hold pressure and thing I have it figured out. Main clamps that were loose were; front heat exchanger, coolant bleeder block, and bottom of t-stat housing. Got the whole damn sled apart for it so I tightened every clamp in sight. Finally held the 16psi for a few hours.

Mine will lose a bit of coolant from time to time, but it’s only when it’s really cold like it was 2 weeks ago. It might lose an ounce or so, and drips out right below the overflow. Fast forward to last weekend, I rode about 250 miles in 3 days and hasn’t leaked a bit.

I have seen this on a few of mine also. I think we have found the problem. I will know in a few days if we can get some riding in.

what do you think it is?

When I pressure tested it, it was leaking up around the cap and thermostat. But until we get the sled out, we wont be sure. No other leaks showed up.

She finally let go.. it was the head gasket seeping.. pile of #*$&@!!

PEFI tune? Is this coincidence or trend?

I wondered if it was over-boosting.. he did see 18 psi on the Stage 3 and 16 -17 on stage 2, and I thought that was odd.. but his exhaust is almost a straight thru design. I am going to check with Thunder and maybe see if there is an update on that tune package.

I dont want to be "Jonny Skeptical" BUT......
It seems when there are burn down/gasket problems on tunes, this tune comes up often.

My guess is the tune for sure caused the failure but there are a lot of factors that can go along with that failure.
