I'm at a loss at how they kept those headers looking like that... I'm thinking they must have been brand spanky new....

Any uncoated headers I've ever had heat discoloured after the first hour or so of running.... Then I learned a little trick.... Painting hot headers with used motor oil.... Put up with the burnt oil smoke and smell about eight or so times and you end up with nice black pipes and not the rainbow of blues up near the exhaust ports... never had coated pipes so not sure if they discolour or not...

Those pipes were likely ceramic coated Eric.

It really works great to keep in the heat and look good too. The Bender pipes below on my old modded sled used look like hell so I had them coated. The tops by the head would to turn orangy brown when the machine was working hard and go right back to red when they cooled a bit. The thing was running on the edge most of the time with EGTs of 1050 - 1150 degrees. Best money you can spend to upgrade and preserve headers.

I miss riding that sled... Used to be a real performer in the mountains. Now it's completely irrelevant with the new machines out. It's now a museum piece. Michelle won't let me keep it in the house though....

Lol... you think they had invented ceramic yet back then Derek.....

We didn't have any mountains where I grew up ion the east coast.... Sleds back then were nothing like what they became in the late 80's and onward.... I remember when bogey wheel suspension gave way to slide rails...we thought that was pretty kewl technology.... there were no shocks or other suspension on the skis then either.... hehe...... .. Then Tillotson gave way to Mikuni carburetors... wow.... lol.... In those days, $2,000.00 was a top of the line machine.... I had a 440 Silver Bullet TNT in 1973 and it was the fastest thing me or anyone else around small town Nova Scotia had ever seen.... lol.... Many years later I drove a 670 Summit and thought it was the quickest, most comfortable, best handling sled ever.... Not.... Every year they improve and improve.... I have no idea now what's out there but my neighbour who leases my cropland runs something that I'm thinking has at least a Z06 engine with both a supercharger and twin turbos on it.... this thing sounds like it must come close to the speed of sound..... lol....

That's quite the hood on your sled too.... not sure if I've ever seen one you could see through....

I’m not certain on the timing of ceramic coating but now I have something to do this afternoon Eric. Find out. Never occurred to me as has been around as long as I can think back. (Like 2 weeks normally).

Ya sleds today are amazing and powerful. The ride and abilities are to the point that without even working at it, they will take you where you absolutely should not be and scare the crap out of the meek hearted.
I used to spend about 50 days every winter in the Rocky Mountains on that old Yamaha.... which was new then.
Nothing you can see in the picture except the skis are stock on that machine. Totally modded out. Was a very fun ride. I went through a few of those lexan hoods. Very light and amazingly tough too. :Biggrin:
 
Derek wanted more horsepower in the ZR1. How about this one….Maybe more than one way to get to 800.
