How Many 81H/SH/LH's produced Post your Ser. #

[Dan Hodges]

The 81 SH started with 4R0-000101 and I have 4R0-000437 which I suppose means I have the 336th. one made for 81 and so I wonder what the total number for the year 1981 was. According to the statement of origin on mine, it was manufactured in September of 1980 and so it must have been an early one however who knows what month they stopped making 81's and commenced on the 82's. What is the number on yours TC?

Well,

I didn't think copying the whole message for just one bike was worth it, so here it is DAN!

81SH 4RO-003482

Have 3H5-004991 engine only!

My 79SF is lower than already posted by half.
I have a 4R1-engine/frame but can't get to it easily to check it!

Your's is over 3,000 more than mine so we know they made at least that many. Do you know when yours was made? There may have been more of these things made than what I thought. I always thought 81 Specials were scarce but apparently not. I know that the 4RO TCI box is hard to find. Thanks for sharing your's with me.

1981 XS1100H 3X1-004006

Just to add another prefix to the mix...

4R1-001542.............just to add another to the mix............and yes, when I bought it new there was a controversy between dealer and State Patrol inspections as to what year it was. Colo. State Patrol decided too costly to tangle with Yamaha, and would loose that contest anyways. Whats really ironic is that when I bought it back after owning it ten years, selling it, buying it back two years ago is that I had to take it to any dealer for a serial number verification as there was still a discrepincy with DMV when I went in for the title change-over!...............Least I won't have to deal with that EVER again. Just a couple other things different with this Venturer1100 are: Ignition still had the slotted adjustable timing mount even though it uses the 4R0 TCI(have 3 extra), came new with the gold top MNS carbs(which was a eye-catcher to me back then, as they matched the gold emblems), and it came with the rectangle chrome mirrors(which are still on bike). Know now that none of that mentioned was the normal for this version of the H............Hmmmmm......interesting.

Mine is 4R0-004891. I am sure it was't the last one made. My other two were higher yet.

The '82 should read '82 XJ1100J not L.....Also it seems the formula for determining the serial # is to take the the serial # and subtract 100....is this correct??? What is the logic behind this???

my recently acquired 81 LH parts bike (wrecked) is 4W1-000948 matching frame and motor

Hey Max,

If you'll look at the original thread, the serial #'s start at xxx-000101, apparently Yamaha wanted to make it easier to count, than to start with 5 zeros?

Mine and Dan's are pretty close. My 4R0 is 000512.

[randy]

My old 81SH was 4RO-004037.

I wonder who has her now?
