No thats a 1986 Model for sure!!!
White fenders and red plastic definitely an 86! It would be nice to see you stick with red and white color scheme.
Looks like a fun project!

If you want to know for sure check the frame #'s on the steering head. Anything 86 will have 1RX as the first three. 85'S have 38W. This includes your shock reservoir, engine and some other misc parts. It good to know this way you can see what was mismatched with 85. But I can tell you that is an 86 frame you have. Good luck with it.
what is different from the frames that you can tell?
85 Tri-z
38mm Flatslide
Boysen Power Reeds
DG Pipe and Silencer
Bored 1.25mm over
Wiesco Pistion and Rings
K&N Clamp on Filter
Compleating Restoration
1rx it is...................86 THEN...........
If I was you I would get the frame and all the old red steel parts powdercoated red again and then go with 85 Yellow Z fenders and shrouds. It'd look sweet IMO.

ewwwwwww red and yellow......nahhhhhhh......remind me not to ask for your help redecorating my house.hehehe.....looks ominous for the engine stripped it today and descovered 2 1 1/2" scores on the front side of the piston and the matching scores below the exhaust port.....and a very small amout of play in the main bearing.....rebuild time,,,,, 8)
Can you snap some pics of the those piston 'scores' on the front of your piston.
I saw that on my 'Z' when I removed the exhast pipe. Are any scores bad to have on the piston...I tend to think it means the rings are well worn.

Otherwise how deep are they, etc?

it's not flat flat.......it's a little domed....dude...![]()
yep, those marks mean bad rings, the black streaks are where the oil/gas has been blowing past them....if you have them its definatly time for a rebuild, or at least hone the cylinder and get new rings
Give me no lip and I tell you no lie.
-TF 05' , And cant wait till 06!
Good Luck with that.
rebuilt the rear shocker and painted it also replaced the front fork seals and painted the bottoms........lookin good.......
