So, my S3 needs bottom end work after all, according to the tech, and I trust this guy, the crankshaft bearing is shot, needs connecting rods, pistons, rings, something done for the cylinders....any advice? I really want to do this right so it will last as I am putting this bike back together as she was my first Buell...money is not really the problem but I don't want to go crazy either. Thanks in advance | ||

Trust, but verify. What is the mileage on the engine? Has it been disassembled already? | ||

mileage 42500ish, yes it has been disassembled to replace leaking gaskets when the tech found the other problems, he was checking the rings when he found the other stuff, he is waiting for me to see him to show me the damaged parts. After looking at the sponsors on this site I am leaning towards Revolution for a kit and have them balance/lighten the crankshaft and replace the bearings, I'll need to discuss this with the tech though... | ||

Really not a lot of mileage on the bottom. Top end, the mileage is about right. Make sure you use a really good oil in both holes when you are done. | ||

I lost a bottom end at less than 20K on my 99 M2. I changed the oil (Mobil 1 20W50) every 2000 miles or so, used an F1A equivalent filter to add oil capacity & run cooler. It's very important to listen to the bottom end sound on these engines. It starts as an odd tick & gets progressively worse from there.

My X1 lost it's bottom end at just over 24K. Same as Knw, changed oil and transmission fluid religiously. | ||

That is interesting. Between my '94 Sportster, the '99 S3, my wife's '01 S3, and my S2 we have over 250000 miles with no bottom end problems. I guess we have just been lucky, since I think you would really have to screw up the maintenance to have that be a factor. | ||

Try keeping the RPMs below 6500 RPMs and see how long the bottom end lasts on next rebuilt ... Have 111,049.7 miles as of the last ride on my OEM bottom end ... | ||

I babied my M2  It's funny, too because years (1995 or so) before when living in Colorado & working with a bunch of snowcat mechanics, I was thinking about a Sporty. I clearly remember one of them admonishing me to listen carefully to the bottom end. I should have listened. No pun intended! | ||

Try keeping the RPMs below 6500 RPMs? My X1 has also been pampered. Never on the rear tire and only hit the stutter box once since I've owned it. That will be 12yrs. and one month as of next Wednesday. And, IIRC the rev limiter is set at 6200? I would assume that even if it's set at the factory they would leave a little room to play with so all of them don't blow up. | ||

Labor is far and away the most expensive component of any repair. Go with a 1250 Kit from a supplier that actually stands behind their product. You're looking at a small incremental over stock parts and improved performance. Some are better than others, get advice from people here. |
