transmission

Hi all - this is my first post. I'm from WA state, and am in the process of rebuilding my 78 xs650 engine. This site has been extremely helpful, and I have used the search function etc.. to get answers to my questions. Anyway - I split the cases and found this broken part in the lower case half...

Got a first one, 72- 306 motor with a grindingly stiff shifter pedal. wont go in gear thinking flip the motor on its head and split the lower case off. 1) access to transmission shifting forks or is it on the upper half ? 2) anyone had this problem and the fix for it ? 3) throw it in the...

Hi guys, need some help. So my engines dismantled got my cases split. Took lots of photos, got my clymer etc. anyways need a few tech tips if anyone's out there. 2 things really. Number one how can I tell what gear is engaged when the cases are upside down and the tranny installed what gear...

Alright, 3rd gear needed to be replaced on the gear set I want to use, so I took one from another set I had. This is what 3rd pinion looks like against 4th pinion. Should I be replacing as a whole set? 4th pinion on the other set had a very rough look to the top of gear teeth facees, or does...

As I disassemble engine components (with the exception of the crankshaft which I just plan to degrease) such as the transmission shafts, starter motor gear parts, shifting mechanism, etc, I've got the following questions: Transmission Bearings: I have completely taken apart the gears, etc...

Cases split today - I may post a "here's how I did it" video later (See Post #6 of this Thread). What's happened to the 2 studs (front ones) that are nasty looking? Are these easy to replace and will I be able to find replacements? What's the proper tool to remove the 3 circlips (#16 in...

Hey guys, Just so I'm 100% on this, in the spot pointed out (not by me, but by Hugh) in this photo, I seem to only have a HALF circlip in my engine. Do I have a broken circlip? It seems in the fiche that it's only half of one. Why would that be? Why not use a whole circlip here if...

Today, I decided to tackle clutch pushrod bushing replacement and countershaft/output shaft seal replacement instead of mowing my lawn. Removal of the stock bushing went well following instructions on mikesxs website. See images 1 and 2. I've removed the output shaft seal (or I'm wondering...

Hey there. I've owned my 83 xs650 for 2 seasons, start of third. When I drove it to work the other day to change the oil,there was a chunk of metal on the magnetic oil plug. It drove to work fine. Had no choice, but rode home fine,too. I have not opened up anything but google, and I think it's a...

So i just finished my bike and a full engine rebuild and took er out for the first time today! Ran good but couldn't shift from 2nd gear to 3rd. Only had 1st and 2nd gear. I assumed it might have been my clutch so i removed the clutch and disassembled and it looked fine. Started playing around...

Do I have to remove the top and the cylinders, or can I just turn the engine upside-down and lift the bottom crankcase and get to the gearbox from there? Sincerely, Felle

Hi everyone, just joined today so hopeful of some useful exchanges of information and interaction. I have a bog standard XS-1B from circa 1971, which I've owned since 2008and love it! I live in the UK and brought the bike across from the US as the early models are rare over here. I ride the...

Hoping to get some clarification. I understand that the Mike's XS 5th Gear overdrive is meant for the 78 and later transmissions but I was told it "should" work fine in my 77D as long as it's also installed with Mike's 05-0857 (Gear - 5th. Main - 22 Tooth)? Can anyone clarify this for me as...

Hello. I have an 81 xs650. Just finished putting Mikes xs taller 5th gear in. After putting the case back together I spun the sprocket and went through the gears with the motor out of the bike and on the bench. All seemed to work well. Side note, I put new clutch plates etc. in as well...

Hey guys, So I THOUGHT I had my new build all done. Took it out for it's first ride on Tuesday and she rode like a champ. City driving here in LA, but all around town. Then, about half way through, all of a sudden a few things happened. First off, in first gear, when I try to engage the...

i have a tx 650 74 model and want to put a late model transmission (1980) has any one done this,are there any problems/ are they interchangeible.its so i can put the 5th gear overdrive in it

This might seem a really stupid question but it's been a looooonnnng time since I ran the bike and went through the gears. I wondered. Should I be able to click through all the gears while the bike is stationary / not running? I have a vague recollection of being able to before I started...

Tearing down & rebuilding a barn find XS650E. Looking at the drive shaft, I found only one "circlip" (p/n 168-17424-00-00) on the bearing on the drive sprocket side. This clip looks like a half-circle piston ring. In all of the manuals I've found, it calls for only one of these. If you're...

I have a junkyard motor that is really close to working.... (the original is being rebuilt). I was having all kinds of clutch issues, so I took the clutch apart and soaked and cleaned the plates in brake fluid, and re-assembled everything with some 20w 50 Castrol motorcycle oil... with about...
