98 S1W, riding home last night I heard a scraping noise when the clutch was out. Pull the lever in, it stopped. Adjusted the clutch and rode to work today, rode fine, but still heard the noise at work. One of the techs doublechecked my clutch adj, it was ok, rode home. Still noisy. Checked the primary slack, nearly an inch (I could just about get the chain all the way out of the window). Put that in spec, go for a quick test jaunt. Barely changes gears, go to turn around about 1/4 mile from home, scraping noises from the primary, have to stomp the shifter to get it into first. Accelerating through first, shift to second with my knee instead of my ankle, let off the clutch, and the rear wheel locks up and the engine stalls. Hm. To say the least. Get stopped (still rubber side down thankfully), pick the seat out of my pucker, eventually find neutral. Start the bike, let the clutch out experimentally and the bike moves forward. In neutral. Slip the clutch to keep it from stalling and eventually let it all the way out - I'm doing 45 at 2k rpm, sounds like fifth to me? Get home (in neutral, LOL), stop in the drive, put it in first, let the clutch out, WHAM. Stall. I'm guessing I wiped something in the trans? Maybe a mainshaft bearing or some such thing? Or did I really kill it and should just start looking for a Baker 6?  Hmm...put the S2 trans in the S1, and a 6 in the S2....and have a REAL highway cruiser! | ||

Sounds like the primary adjuster shoe broke.Did you have the updated one?? Time to open primary. | ||

Sounds like your chain tensioner came apart. If you're lucky, all you'll have to do is pick the broken pieces out of the primary and put in a new one. But you need to be real sure you got all the pieces...might want to pull the trans and have a look. There's an upgraded version of the tensioner, search the KV for part number, make sure you get the upgraded one. rt | ||

Great minds run in the same gutter, eh Jim? | ||
| Firemanjim |
I was wondering who that was down in the depths with me??? How be the road-oiler ? I see somebody else was having a problem with a hole in his crankcase--- | ||
| Ratbuell |
So a bad primary chain tensioner will make the bike run like fifth gear in neutral, and make the trans lock up completely when put in first gear, and stall the engine? Hmmm.... I mean, I'll take it...but it sounds to me more like a trans bearing/shaft problem? This is what I get for not having broken this particular part of a bike just yet, LOL. I hope you guys are right! | ||

Road-oiler's back together, I put about 50 miles on it last weekend, but I lost a rocker box gasket (one of the rubber ones) and had to cut my ride short. When I got it apart, all four of the rocker box bolts on the rear head were loose--sounds like a little brain fade on my part. I think I snugged 'em down and forget to torque 'em. I was hoping to ride it some more this weekend but I had to cannibalize a breather bolt off it for the road pig. That motor is really sweet! rt | ||

Rat--sorry for the 'jack. You could well be right, but the old-style tensioners seem to fail more regularly than transmission parts, you'll find out for sure when you pull the primary! I'm guessing that pieces of the broken tensioner could have been fouled up in the shifter, kind of "confusing" it. rt | ||
| Ratbuell |
Nope. Primary's off as of about five minutes (and an adult beverage) ago. Tensioner shoe (with a whopping 3800 miles on it) - perfect condition. Something in the trans let go, I was afraid it sounded like a bearing scream. Grrr... I didn't think it was a shifter thing. I've had shifters get confused, but never LOCK the trans and kill the motor as soon as you twitch off the clutch. Ah well...I've been looking for an excuse to get the gearset micropolished at work, LOL. | ||
| Road_thing |
Bummer. At least the trans is easy to pull! rt | ||

>>>kind of "confusing" it. I think I may have swallowed one of those devices as a yute. | ||

As long as you didn't inhale, it's OK... | ||

Ratbuell, Check your clutch basket. My 99 S3 basket came lose at @ 19k. Joe | ||

I've got the clutch off and the trans ready to come out (as soon as I find a 1-7/8" socket to pull the belt pulley off), and if I move the pawl around I can still get it to lock up. I either broke/bent something, or the bike (from sitting for so long - it was 8 yrs old with 1000 miles on it last year when I bought it) had pitting on the mainshaft from sitting and it finally locked up to one of the gears. ....I'm one freakin' socket away from an answer. It's killin' me. Sears stocks the size, but they're out (of course). And I hate borrowing the specialty tools from work because I'm weird...I just don't like using other folks' tools. <shrug> Might have to though, just so I can get the damn thing apart. | ||
| Road_thing |
Rat: I bought a full set of large 1/2" drive sockets from a local Asian tool merchant (Tool Club) for about $70. They ain't Snap-On quality, but they get the job done. rt | ||
| Ratbuell |
Well, Sears didn't have them and when I asked when they'd be in I got a <shrug>. Went to Napa, they'll have it tomorrow by 9am. Little more $ (nearly $30 for one socket)...but at least it'll be here and I can finish stripping the damn bike down. LOL. Three days...ONE NUT HOLDING ME BACK. GRRRRR. | ||

Rat- You don't need to pull the front drive sprocket (1 & 7/8" nut) off in order to get the tranny out (well most of it anyways). The mainshaft slides into the 5th main gear - the 5th main gear is pressed in the bearing that is pressed in the case. If you have the 5 (?) bolts that hold the trapdoor in the tranny should slide right out. 1313  | ||

1313 i was thinkin the same thing, "why is he takin that off" lol........ dont open that can of worms unless ya gotta. | ||
| Ratbuell |
The "why" is, I was pulling the trapdoor out with a lever and it seemed to be pulling off of the mainshaft. It did NOT want to come off. I figured (and the manual pointed me in this direction) it was stuck to the sprocket and I had to pull it off to get it out. The other reason: when I'm in neutral it acts like I'm in 5th. So wouldn't it follow that 5th is stuck to something it shouldn't be stuck to? | ||
| Reepicheep |
Sounds like it could be a "welded" on 5th gear drive assembly... Pulling that sprocket won't help you though. Maybe a really thin strip of metal would let you get in from the sprocket side and chip away at whatever goo has stuck the parts together. Mine was a rusted mess when I pulled it to repair it on my Cyclone. You could start tapping through the middle of that 5th gear drive assembly with a punch, but thats probably going to ruin at least two sets of bearings (one of which you have to ruin to pull the 5th gear drive assembly anyway). | ||

Rat, You might want to pull your clutch plates apart and check the condition of the spring plate which is in the middle of the clutch pack. The rivets that hold the spring plate together have been known to come apart then cause all sorts of problems. | ||

yes, I have heard that too. change that part out.....I have 40,000 plus miles on mine, and that is worring me...rex | ||

Well, it looks like the problem was a walking mainshaft. There was a roached bearing inside the belt pulley and the mainshaft had walked away from the trapdoor, letting the gear closest to the trapdoor walk sideways into another gear (on the countershaft). Explains why it would drop in and out sitting on the axle stands idling... So, the required tally: mainshaft, all bearings, all seals The 'upgrade' tally: billet trapdoor from the old race program, micropolished gears and shift drum The 'maybe' group: clutch pack or pieces, going to press it apart tomorrow; fifth gear case bearing (have to press it out to replace the pulley needle bearing) <sigh> I think the damn thing just sat too long before I bought it (in '06, with 1100 miles). On the sidestand (where it apparently spent most of its life), all the fluid sloshed away from the pulley and 5th gear bearings, letting them get moisture on them, pit/score/rust...then me driving it nearly 3k miles in a year (albeit with Syn3 in it) cooked it out. | ||

Ratbuell, This is valuable info. I have a 98 S1W sitting in the garage, that has set for 4 years on the side stand in an unheated shed, now to form a plan to bring it on line this winter. Thanks Joe (Message edited by bad_karma on May 06, 2007) |
