Update on cryotempering
Well I got the motor out after 48 hours at -109F (-80 c), and put it back on my bike - it runs !
Seems a bit weak, this is a DAX F80, I was quite happy with the power on my previous DAX, I think his series on that one was a D65 or something. A couple of observations:
1) they pick up considerably after break in
2) I have about 550 miles on my other new ride, rear mount DAX titan, and have gotten used to the low end torque
3) Cryotempering might have warped the head, possibly. But it looks fine, and after my 15 minute 1st run there is absolutely no leakage around the head gasket
4) Cryotempering could have damaged the magneto (I didn't take it out), although seem like it would fail or not fail. I will wait for 200 miles or so to see if it picks up.
5) Cryotempering could have weakend the magnet. I will check relative strength against the other 6 or so (!) I have in other motors using a screw driver or something.
6) I believe the F80 actually does have more CC then the D65 believe it or not. Wondering if I need to change the setting on my carb needle. Anyone have any experience with this ?
Well, my bike looks sweet, I came into a little money (sold some stuff on ebay) and got a new basket, touched up the paint job, put a 12 volt MR16 LED lamp on the front (I rigged up a 12 volt battery pack a couple of years ago with an LED taillight and wire to LED head lamp. The MR16 is only about a watt I think - going to get the one with 3 crees eventually - 300 lumens or something - 7 watts - it screams ! I will post an updated picture.
I will update with progress on my new motor. One step at a time. If anyone has any insight on a weak motor, particularly DAX F80, let me know. I will update mileage every couple of months
