There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

I have never been a fan of torquing spark plugs. The gasket makes a good torque reading difficult (and sudden). I don't recommend you follow my lead, but that has always worked for me. Be sure to choke up on the ratchet, especially with aluminum heads. If you do torque the plugs, sneak up on the setting, as you should when torquing anything. For 14 lbf-ft, go 8-10 first run, increase to 12, then do the final torque to 14.
Those plugs look a bit rich down deep, but the tips are lean (most recent operating range. I'd say you still have some adjustments to do in some ranges. Keep in mind that it is very diificult to read plugs with today's engines and today's fuels. Lean engines burning part ethanol gas don't leave much color. It is also very difficult to do the reading right, for the most part...running full throttle then cutting the fuel and ignition simultaneously, and coasting to a stop to read the plugs. You can't get good readings at other throttle conditions, either. That is why oxygen sensors and exhaust gas analyzers are in use these days.

Thanks for the input... I've got the new plugs in now... seems to run smoother... but that could be just me.....
I know I was running rich before when I had my fuel pressure up at 63... now it's back down to 52 and I'm using the JB to add more fuel.
I also had a leak in the righthand y gasket.... just replaced both with the Honda version...
Now just need to do oil change and lube and I'll ready for Cuba.

BRP states it is a good idea (required) to install some thermal paste on the spark plugs when install or reinstalling them.
Hope that helps.
Cheers.

Hi Firefly. How hard was it to change out your Plugs.? Did you use the BRP paste on the threads ? :dontknow:

I used the Radio Shack paste as it was easy to get....and cheap.:thumbup:
The plugs were easy to change.... mainly because I no longer have that big black airbox installed. The front one will be a bear to get at with the airbox in place--- so I think you'll have to pull the airbox to do it.
The rear one is really easy to get at.
