Synth vs dino

Make sure you use only Synthetic air. The good stuff with 78.09% Nitrogen.

Oh **** I have been using regular air (oxygen) do you think that will ruin tires? Can I buy this nitrogen mix at the store? Of do I have to order it online? Can I run tubeless tire on spokes wheels if I use your "nitrogen mix" ? Or will I have to continue using expanding foam- it makes the tire hard to get off. Like they'd done a lot of coke.
 
Nitrogen is the single greatest rip off I have personally experienced.
They jam it through on new car contracts as "nitrogen for life"

How they can fully evacuate the contents of a tire is beyond me.
Charge 100 bucks for the privilege too.
 
Even better than that, KaleCo Auto has you covered once again: Seasonal Tire Air.

Synthetic does not reduce friction or reduce wear under any normal riding conditions.
This is false information. Be careful what you believe on the internet.
 
OEM air all,the way...check out ebay....looking for the link, will edit post once found!!!

Double dog dare you to go to Bob Is The Oil Guy and start a thread proclaiming synthetic oil reduces friction and wear.:-\\\
 
Let's get back to my original concern. Please look at the attached photo I snapped a few minutes ago. It is the front of the engine of my 1100EZ with almost 25k miles. As soon as I bought it, four months and 500 miles ago, I changed the oil and filter. I used Motul "3000 10w40". The previous owner said he used dino. I don't think he had the bike long and, although I don't consider him trustworthy, I don't think that's something he would lie about.

Question 1: Could someone please identify the area between exhausts 2 & 3 that is apparently seeping oil?

Question 2: Two inches directly above is another wet area. Is that the valve cover?
 
More seep

More seep

All other considerations aside (including the fact that I should, and will eventually fix the cause of the seeping), will a switch to synthetic now increase the oil seepage?
 
Yes, a switch might increase the seepage.
The top seepage is the valve cover gasket, an easy fix with an OEM only gasket.
The lower seepage is the head gasket, a more interesting one to replace. Have you checked the torque on that particular bolt?
 
I have used and currently am using several aftermarket valve covers and aftermarket half moons. No issues. I think I got one from Z1 for like 11 dollars a few years ago. I had a problem with a silicone Realgasket. It kept extruding. If it is a lot of work to get to, like a head or base gasket, I use OEM.
 
The top leak is the valve cover, easy to fix.

The lower leak may or may not be the head gasket. I have seen oil from a leaky cam chain tensioner show up there. Hot oil swirling around can get most anywhere. It can go through the air passages between the cooling fins and end up there. Worth a check.
 
Oh and do night be zealous in tightening any bolts
You cannot fix a fully compressed gasket by over-tightening bolts.

You may end up stripping or breaking something.
 
I had two (2) aftermarket valve cover gaskets go brittle and break on me. Then the oil, which was supposed to stay inside, began to venture outside.
Since then, I use OEM. YMMV.
