Nice looking chart, I'll be its fun to ride.

 

I purchased a kit from Marlin to keep an eye on my head temp. Spent most of the day trying to decide were to tie in my power to the gauge. I did not want to splice into a manufactures wiring harness so I did a Radio Shack DIY hook up via the battery. from battery connected 1 amp fuse, spst switch , with idiot light that stays on if switch is open or closed, I just disconnected the light, then went to gauge and jumpered to gauge night light, other wires went to grnd and sending unit.
I originally was trying to find the ignition wire so I made sure everything was disconnected like fuse, battery, key off , etc. I started to disconnect harness for ECM, which I thought was the BCM, and the alarm went off in my ear. Scared the crap out of me. I guess the Harley alarm system has a back up power for the alarm system. When ever you play with electrical wires and you hear a loud something , it always scares me, due to previous shocks in my life. After I removed the seat, to check out wires and could not find any loose to tap into, pulled headlight and same thing. Harley has some tight electrical harness stuff. So I gave up , put everything back , best I could and got power straight from the battery, no warranty problems, except for the battery. Started up with 70 deg air temp. Checked cylinder head temp and after running for about 20 minutes , it never got over 230 deg on gauge. Matched my laser temp gun fairly close. Im happy. Turned engine off and realized my water cooled radiator fans had been running. So I am going to check out further when air temp gets in the 90s. Clean looking gauges. I just have to remember to switch off the power to the gauge or it will draw down power from the battery.

 

Piggyback the cig lighter connection.


OH... next time you mess with power, disarm the alarm. Man, I hate when that happens.

 

Mr. Wizard, I removed fuse, disconnected battery and unplugged a heavy red lead to the ECM and the alarm still sounded. I guess that is a good thing. Maybe a capacitor is somewhere in the system or secvurity component that will at least sound for a short period of time, even when the main battery power is cut. Learning all the time when I work on the bike, and that is a good thing.

 

The smart siren has a battery backup.

 

yup

A 9V battery that should be replaced every few years like the Fob battery

 

Is the only concern with the 255 cam the cold cranking compression?

 

Perhaps I should have said a 255 on a 2014 trike.

 

The added compression from the very early intake close does make for an engine not tolerant of poor fuel unless you really work with the timing, which then kills power. IMO the 255 isn't much of an improvement in the 2014 Trike since the new cam they are using is very close to the 255.

 

MSOCKO3, Thanks. Wish I could return the favor--perhaps some day I can pay it forward.

Can I get curves for the new cam? I did not know they had changed the cam. Any specs?
