Going back to work after lunch and was taking it easy (seen a cop) and rear wheel locked up at 70 pulled clutch in and coasted to a stop while floating to my final resting spot tride to restart nothing but cliking from starter i think motor is locked up, had oil in it, no sounds or lights came on i need some in put before tear down | ||

Put it in 5th gear and try and push it. I'd be surprised if the motor just all of the sudden seized, assuming good oil pressure. | ||
| Whitethunder |
tried that already got nothing | ||

Good thing you were able to pull the clutch in that fast, could of been painful. | ||

Pull the primary cover and chain I guess to see if its motor or trans not sure if that will work on sportster set up though never had that problem arise | ||
| Akbuell |
WOW! Really sorry to hear that. Glad you were able to coast to a stop! Since pulling in the clutch allowed coasting, I would think the trans is down on the list of problems. I would pull the plugs first, and see if they tell you anything. Pulling the primary cover is a good idea. Put a wrench on the engine sprocket, and see if you can turn the crank at all. If you seized a piston, you MAY be able to turn the engine over via wrench after it cools down. In any case, pulling the top end and gearcase (cam cover) along with the primary cover will be in order for a look-see. | ||

No noise before the lock up? | ||

Pulling the clutch and letting it freewheel pretty much rules it down to either something wedged in the primary chain, or a motor issue. | ||

You can also drop your oil pump and get an easy peek up in the cam cavity... though it seems unlikely you will get out of this with less then a total rebuild  | ||

I had the same experience at at only 1000 miles.The spur gear to the oil pump failed. Buell replaced the engine under warranty. I had been very lucky to get the clutch in too. I Think it happen mid-shift to fifth gear and that may have saved me. It was a wild ride for a minute or so. let us know what you learn. How many miles are on the bike?

ouch..... this doesnt sound good at all  | ||

Sounds like the oil pump gear stopped gearing. Before you try to turn the bike over and cause anymore damage remove the oil filter and cut it open with a hacksaw. Lots of metal means it's probably time to have a look in the cam/oil pump drive area behind the case on the right side of the engine. | ||

Good chance the motor is done for. | ||
| Whitethunder |
thanks for the input guys i will let you know whats up going to tear it down soon.I cant live with out my baby so it has to be fixed | ||

Pull the oil pump and check the drive gear first. | ||

Pull the oil pump and check the drive gear first. +1 Check the KV for numerous threads on this, mainly regarding tubers. Remove two screws and loosen the front oil line to drop the oil pump. Look up in the hole to see the drive gear on the crankshaft. Bump the engine and recheck several times. Taking photos with a digital cam makes it easier to see. Drive gear on crank can wear excessively, eventually break, shards go through the cam gears and can wreck the whole mess. | ||

A possibility is also the primary chain adjuster. If the engine lost oil pressure you would think it would stagger and then lock. To stop dead it may well be something caught in the primary gear/chain. | ||
| Akbuell |
Just wondering if you had had a chance to look at your engine, and what you might have found. | ||
| Whitethunder |
i have not dug into it yet but i was wondring if anyone new where to get a rebuild kit for the motor if i need it | ||
| Moosestang |
When rebuilding these motors, do you normally just replace the cylinders or have the old ones machined? | ||
| Akbuell |
FWIW, happened to be talking to my Harley/Buell dealer today, and mentioned this thread. He said that the same thing had happened to his wife some time ago when one wrist pin (Sportster)decided to wedge itself into the cyl wall. Made the con rods do some weird new shapes. As to a rebuild kit, never heard of one for these engines. Get a gasket set, then disassemble, inspect, measure, and replace parts and pieces as necessary. | ||

How many miles are on this bike ? | ||
| Ochoa0042 |
what's the verdict of da problem? | ||
| Moosestang |
I don't think he's had time to work on it. Me, i'd have had the whole bike apart by now!  | ||
| Whitethunder |
well i work at a bike shop in western ny call custom addictions and have not had time to work on it but i suspet it is the oil drive gear |
