I have a 1997S one lightning. The motor was recently rebuilt and has just been broken in at about 2000 miles. A couple of nights ago I was riding and when I came to a stop sign the bike shut down. I pulled over and realized that the oil seal to the oil cooler had loosened in the oil engine oil leaked out. The engine did not sieze. I let it cool as I walked to the gas station and bought 2 quarts of mobile one which was more than enough to fill the tank. The bike turned over but would not start. I pushed it home, luckily I was within a mile of my house. The next day I change the oil again but the bike still would not start; it turns over fine; it has plenty of spark; it has gas it just won’t start. Any ideas would be appreciated. | ||

Do a compression check. Hope you didn't get it too hot and crack a ring. Can have all the spark and fuel you want, but have no compression and it won't want to run. | ||

Exactly how bad was the leak? Was it a slower leak that you were able to top off, or did all the oil drain out and you were running it empty? I assume if you bought 2 quarts of oil to fill the tank, it was a pretty good leak? | ||

The leak was pretty bad. It drained most of the oil. I am worried that Bluelightning is right... I'll have the compression tested this weekend. | ||

Mike. Your profile says: "Handles like a tank. Doesn't want to go into corners and doesn't want to stay in corners" I've never heard anyone describe an S1 this way. Maybe check to be sure your suspension is set up correctly for your weight? Is there an oversize rear tire on it? Front tire scalloped? Something is up, because it should not feel like that. | ||

Lol! I should update that. When I bought my Buell the suspension was set up for someone that outweighs me by 100lbs. I had it dialed in for me by a buddy of mine that raced for years and owned two Buells. Now it is amazing! Night and day. Flickable, stable and torquey. I just hope I didn’t ruin the motor... | ||

Nice thing about a sportster is lump its fixable | ||

All the bearings are rollers and balls so they are probably fine. Theoretically, if there is any oil in the tank at all, the bike would still have pressure. | ||

What psi should I have on a compression test. I borrowed a compression tester from a friend. I never used one before but it looks pretty straight forward ( which means it’s probably not ) and I am getting 50 psi in the rear cylinder and 40psi in the front. Is that even close to reality? | ||
| Steveford |
No, you're down around 150 psi. Do you have the throttle opened up all the way? | ||
| Canyon_biker |
I tried it with the throttle opened and closed and used a different tester. 50 psi in both positions front cylinder. I haven’t checked the rear but I suspect the same.  | ||

Stuck valve? | ||

If you have a diaphragm type carb, make sure the throttle is open and the slide is held up. A couple of options. Might put a small amount of oil in the spark plug hole, turn the engine over a few times, and try again. Or a leak down test. Nothing wrong with a borescope inspection. The best option, since you will most likely have to do it anyway, is to pull the heads and look inside. Hope this helps, Dave |
