Difference in gas tanks....86 to 88???
(Click here to view the original thread with full colors/images)

Can anyone tell me how to determine what year gas tank I have?

I wanted to order a billet gas cap but I was told when I went to order that it would only fit the 88-89 250R.

I have no idea what year tank I have for my project.

Can anyone help me out?

Thanks

One way to tell if you have an 86-87 tank is by looking at the side of it. There is a rubber strip that is held on by 3 phillips head screws. 88-89 tanks were red color only and had a black rubber strip that was glued on. I think 86-87 gas tanks used a different gas cap then 88-89 tanks as well.

All of the above is correct...You can order a gas cap for the 86-87 from Duncan racing...I got one on the way I'll post a pic of it when it gets here if you would like.

my 88 doesnt have anything on the sides, the 86 had the red strip with the screws. I didnt that would affect the gas caps. I can go check and see if they swap......

The '86 tank came on the '86 R, and the '87 came on the '87 R?

There is a difference, while it's not important, it tells you exactly what year it came from.

Why must you know everything about 250r's and play these little games of yours

well when you have that many R's (see his sig) I guess you can pick up on each minute detail

Im going to guess its either a slightly different mounting or the 20:1 ratio imprint??

one of these days

I'll have an 85 and 86 ATC and one each of a 86 to 89 TRX along with maybe a laegers and roll framed R's. That would be flippin sweet

i think I know the answer!!

86 has a bolt/grommet above the petcock and the 87 doesnt?? I have three different tanks, the 88R, the 86R and the 350RX conversion which I now know has an 87 tank? ......

We have a winner, 86 tanks have two phillips head screws with black grommets on each side. 87's only have one per side.

WOW! You have some experience with these 250R's I'm guessing...
