Default Bad Flywheel

Hey guys thanks for having me. I recently picked up a 2000 Night train with 15,000 on the odometer. The seller told me it had been converted to gear drive and had a cam put in. Well the other day I found a pin hole fuel leak on the gas tank right at the rear mounting tab. I took a trip to my local bike shop and without seeing the tank or the bike the owner sounds confident that I have a bad motor, more specifically a bad Flywheel. All I can tell you is that it shifts just fine, has plenty of get up and go, and the vibrating I do notice doesn't seem to harsh. He threw out a rough quote of 3500 to replace the flywheel. Does any of this seem right?

Short answer, no. Run fast. There is no way to diagnose a bad flywheel by a fuel leak. Find somewhere else to bring your bike, because it sounds like that guy is full of it.

I know it was early when you posted this..
Find your meds, take them, then read your post and see if it still makes sense.

​​​​​​Oh you must be "that guy" every forum has one. You can't clarify so you come up with some cute little quips to boost your post count. Pleasure to meet you.

If your question is sincere, then I apologize.
I've seen more than one 1 and done post here that are looking for reactions.
Maybe take a pic of where your leak is coming from.
As stated above, take it to another shop.

Definitely sincere, nothing I hate more than getting my time wasted, I wouldn't waste yours. I'll try and get a picture up after work. It's leaking at or near where the rear mounting tab is welded at the tunnel.

Check the petcock area and all your fuel lines. Fuel leaks have a way of traveling. A leak from the tank itself ie a blow hole in a weld is possible but unlikely. Best way to check those that I know of is to pull the tank and pressurize with air and do the soapy water test.

If the guy is diagnosing the bad crank over the phone based on a fuel leak, I suspect that he's looking for work that you don't need.
