As long as the insert threads are fine, it doesn't really matter. If you're really scared you could buy an oil pan from a wrecker but I wouldn't bother as long as it works. Maybe go to home depot or Rona and get a big ass rubber washer which will seal and also add some friction to help keep it all together. Is it a new(ish) bike? Maybe for fun call the wreckers or check ebay every 6 months or so you may be able to pick up an oil pan somewhere.
A quick check on the internet you can get an oil pan for a gen1/2/3 for $168 new. For the water Bandits Gen 4's I'm not so sure.
Try these guys.
www.bikebandit.comDon't worry about being part of a "clique" chances are they are just posers anyway. Ie. Your average Harley owner which for some bizarre reason went from a motorcycle company into a fashion house where their bikes are just part of the fashion. Buell wanted to change that but Harley got scared when Police depts in the States started to want to order the Buell ULYSSES police bikes instead, due to reliability problems with the Harley Police bikes. I guess they didn't want to compete with themselves. I find it funny that the "experimental/entry level" division of Harley was blowing away their mainstream bikes, despite using their engines.
Don't get me wrong, when I was helping out my friend for a week during the summer rush at his bike shop I had to break in a new 1200 motor that he installed for a customer on an 883 sportster. There was some sort of nostalgic factor when driving it and it was torquey, I "get it". But after riding the Bandit I was underwhelmed. Also the customer wanted some cheesy ass skull shit we had to put on all over it, which didn't help any. I'm sure the skulls look cool somewhere in the world but it was horrid trying to look through a tiny ass skull mirror that kept coming loose so I wouldn't die while changing lanes. But for a 1200 it was kinda lethargic, maybe it needed more skulls?
Although it was funny as hell watching my friend and I swear like a sailor trying to attach those cheap chinese Harley "custom" parts that didn't fit properly, were loose, or fell apart after the engine started. I laughed my ass off!
I know it's kinda sad that Buell got shut down but to be honest I think it's for the best. Buell actually wanted to make motorcycles that could compete or be better than anything out there and that kind of scared Harley considering their performance and reliability record. Harley wanted Buell to be sort of a "stepping stone" for people to move up to a Harley, however riding a Buell, a Harley after was a huge step down not a step up. Despite using the archaic engine that Harley still flogging around he pumped out as much as he could out of it and had awsome bikes with some very novel solutions and inventions. My friend built a Buell from parts and that thing is phucking awsome. For Harley though I think the end of the Road is in sight. As soon as the baby boomers get too old to relive the "easy rider" days or die off. Harley is going to be in serious trouble, they are trying like crazy right now to go oversees as some other people in other countries still consider Harley's a bit of a novelty but that will wear out as soon as they drive something else. Buell would have saved them in the long run but they closed it down after realizing their bikes performed like crap compared to them.
Thank god that Buell is back with the EBR brand(Erik Buell Racing) and he has a top of the line bike now but will be producing other bikes as well soon. I wish him all the luck in the world. Who knows if they are priced right I wouldn't mind getting one considering he's using ROTAX engines which have a good reliability record and great power. His current mill stock is 175 Horsepower! Thats alot for a V-Twin.
