More to come tomorrow including: 250R (1-6), 250SX (1-3), and all the others...

Please scan ATC 110 difficult shifting.

My ATC 110 transmission has a lot of false neutral positions.

Others have related their experience with broken shift drum stoppers.

I want to see Honda's recommended fix.

I'll start cranking them out this weekend. Any votes for the first ones you want to see?

This Is way Cool. I have learned a bunch already. Broken Crankshaft on 250ES caused from over reving and if the crank was replaced then it should have a punch mark in the lower right corner where the engine # is embossed.

My feelings exactly.
Kinda scared to read it however.
My life revolves around the 250 es models.
so? just overrevving?

I've seen that happen with people who 'know how to ride' and think that the 'automatic transmission' will shift itself...and wind them to the sky.

I guess if they've made it this long, they'll be ok since we rarely get out of 3rd gear and double or triple idle speed.

Yeah, shift fix for the 125m would be interesting too, well, ALL of it for sure.

ATC70

Note: Bulletins #1 and #2 are not included in the paper copies. Apparently, they are on a microfiche (called out in the Table of Contents, shown in post #1)

ATC70 #3, Revised 9/12/74



ATC70 #4, September 1985



NOTE: This next bulletin is for the CT70. However, it has a tip regarding the points sticking open when the machine is hot, giving a difficult to diagnose situation. It seems appropriate to include here since the ATC70 uses points as well.

CT70 #3, 8/14/70

Special Request: CR125R Bulletin #8

[UPNATM]

Just wanted to say thanks for taking the time to scan and post ups these tsb's. I know it can be somewhat time consuming. I look forward to seeing the SX ones.

Ok. The next block are the service letters (SL). These are more generic. I've been pretty indiscriminate: if it related to ATC's in any way, I've included it. Some are not useful, some are entertaining, and some are actually informative.

SL #16, August 1986




SL #17, October 1986




Good one here:
SL #18, January 1987 - CDI Inspection and Troubleshooting







SL#48 Revised June 1987 - Preparation of New Batteries





SL#78, 6/26/68 - Installation of Transmission Cir-Clips



SL#84, 5/4/71 - Valve Refacing Not Recommended



SL#98, 6/8/73 - Chain Damage Due to Improper Battery Vent Tube Routing




SL#104, 4/26/74 - Gasoline Octane Numbers (NOTE: this is old, so when reading it, realize that the owners manuals for our machines specifies "Pump" octane which is the R+M/2 formula. I included it since I thought it was interesting regarding octane numbers in general)



SL#106, Revised October 1982 (NOTE: Store your speedometers in an upright orientation while on the shelf...)




SL #110, 7/31/75 - Hydraulic Brake Bleeding Precaution (NOTE: Why you don't want to pull the handle all the way on some masters...)



SL #111, Revised 9/13/78 - Motorcycle Washing Precautions (Not as silly as it seems, some common sense here, but worth a read)



SL #114, 10/17/75 - Chemical Damage to Battery Cases

GOOD ONE ALERT!!
