I just mounted a Dakota Digital cylinder head temp gauge. It was a fun project, with a couple of twists. It's a discontinued rectangular model ($117, still available on their web site) desgined to sit in a big dashboard, of course, so I built a watertight box for it (welded steel) and then mounted it on insulators next to the air filter box. It works well, and so far the highest temperature recorded has been just over 300F. But then, I haven't been out riding on it yet, I'm sure it will get hotter than that!. I'm looking for any benchmark figures anyone else may have been getting... I came across a thread mentioning cylinder head temp gauges here a while ago. Has anyone else installed one and been keeping records?

Look fwd to seeing your results Geoff. Sorry, I can't help with a baseline, but does this unit use a probe? If so are these temps indicated from the front or the rear of the cylinder? I was wondering too whether there was much difference between front and rear of cylinder at cruising speed due to frontal airflow etc.
These figures will be useful for my H2O injection system I'm playin' with.

LSM we need to talk!

I'm thinking about vapor injection too! (On my diesel mod). As well as oil cooling. A tool you might find interesting and useful is the Veypor computer... I'm looking at it... it contains built in accelerometers as well as some sort of mpg algorithm (no actual fuel measurement takes place) to give you a pretty wide range of information on your bike...

The probe for the cylinder head temp gauge fits under a spark plug or a head bolt. I believe that you can get two cylinder models, which means you could put one probe on the front and one on the back and see what kind of temperature variations you find...

I will start keeping figures as soon as I get the dam kickstart fixed grrrr!

Look forward to seeing some figures. I often read that Brit bikes had high cylinder temps due to poor combustion chamber shapes. This high temp would suit the vapourisation of H20 and the 'injection system' may help to keep it all a bit cooler when required etc

Today after a half hour ride in near 90 degree weather it topped out at 370 degrees.

Boy she ran nice tho, idled perfectly. The battery cover did fall off and the mirrors needed tightening, but otherwise a very pleasant ride!

On my harley-Davidson XLH1200 I've used a oil dipstick with a thermometer on.
Is there any model avaiable to the RE?

[geoffbaker]

Haven't heard of it, sorry!

I drilled out the rivet holding the stick on the cap...
re-drilled to a larger diameter to accept a $5.oo meat thermometer,
then used a little JB Weld to fasten in place.

That might be my next mod... but I might spring as much as $15 for a chrome harley oil dipstick thermometer...

Does Harley make anything that costs 15 bucks?
I thought that HD stood for hundred dollars.

[geoffbaker]

tr,

you are quite right; the last thing that Harley ever sold for $15 was a mild steel unchromed washer, back in the late seventies.

I should have said "aftermarket dipstick thermometer sized for Harleys"

My apologies.

[the_roadking]

I've seen those for differente makes of motorcycles, just wandering if they fit the RE.
Still have my HD dipstick.

I think Germany just invaded...

Not sure what those links were for...?

[the_roadking]

Some stuff I've founded. The price is good and the quality is fair.
