...... but the 40 degree temp drop on the cylinder as measured on the fin by the spark plug.

40 degrees??!!  That sounds remarkable.  Clearly it runs a bit richer with the PC, hence less waste heat, but 40 degrees sounds amazing.  I'd love to see a few more before and after measurements to get some idea of how representative this is.

Howdy Gents!  This is my first post.  I have recently acquired a 2014 Bullet w/ a Cozy sidecar.  Love the ride!  Since I am new to this bike, I have yet to change the oil on it and would like to be directed to the proper thread so as to peruse the process.  Looking forward to hearing from anybody.

RP... you're going to get a lot of opinions on this. Oil choice can slightly vary depending on the climate conditions of your riding area. You may want to go with a 15-50 if you're out and about now; but may want to go with a 20-50 this summer... again opinions and your mileage may vary. Myself I run Klotz 20-50 in my 2014 C5

Thanks NorEaster!  I'm a moderator on the F800.org site and there are plenty of long threads about what oil to use.
I was thinking of using Amsoil 20/50.  I had very good results with it on my ST 2 Ducati.

Roadpizza,
Welcome to the group! Amsoil 20-50 is absolutely fine. Do the oil and filter changes at 300, 600 and 1200 miles up front and stay below 50-55 mph.......you will end up with a very nicely run-in engine.

I was running Amsoil as that is what I have run in bikes I owned before. I was getting a tick noise and a local dealer recommended I run the Klotz. After running the Klotz for a bit that extra noise has gone away.
Not looking to throw a dog into the fight ring... just relating what that dealer told me... he told me that if I didn't run it, it would void my warranty.
I figured he just wanted me to buy the oil from him. I did... and it works fine in my bike.

Were the Amsoil and the Klotz the same viscosity specs?

[NorEaster]

yup 20-50

[mattsz]

Huh.  I wonder what the noise was that the Klotz oil "fixed"?

[NorEaster]

Not sure but the clicky sound was less noticeable after changing to it and running it a bit.

OK….Now what is up with the tool boxes? What makes them so hard to open ( If you can get them open).  I am about to drill a small hole in the case to equalize air pressure or to stick a compressor hose in them to blow the hatch.

I don't know!  Mine have never been a problem.  Maybe they're just "stuck" closed, and need a little silicone lube on the rubber gaskets?  Anyone else have a problem?

For the C5 boxes, press them closed a bit first then turn the key.  Makes it much easier.

+1 and lube up the rubber grommets that hold the pins in place. I took my tool roll out shortly after I bought mine and could not for the life of me get it to go back in the tool box and have the lid go back on. So I now use a fork bag because the toolbox was such a pain to deal with

Sometime in the summer I will repeat my temperature measurements with and without the PCV. The only flaw in the test was that I changed from the standard catalytic exhaust to the sports exhaust at the same time. I got a 40 degree difference on my regular test loop using a handheld infrared thermometer. This is similar to my 35 degree difference doing a remap on my 2007 Guzzi 1100 Breva, and the Breva retains the standard exhaust system. By far, the biggest benefit to the PCV  is the reduction in running temperature. You don't need a thermometer of any sort to notice the difference, you can put your bare hand on the fins for a few seconds before pulling off!

I just wanted to say thank you for this thread. I have been lurking on this forum for the last year or so and learning a ton! My 2014 C5 Military will be delivered here in the next few days and this thread is helping me to prepare. I sincerely appreciate it! Keep up the good work!
