You are pushing it "pretty" hard at 70mph but she'll do it and keep doing longer than your a$$ will hold out. Listed Top speed is 87mph. I'm assuming this is top cruising speed because I and many others have gotten stock machines to (indicated) 100 mph but Im sure I can speak for the others when I say 70/75 to 100 took forever. If you're in top gear you're pushing it 70% of max. This aint a speed demon. Even with a lot of mods it's best at smoking everything 0-60.
Chain conversion really helps a lot. The belts are awesome. Whole time I kept the belt I didnt need to adjust it or do anything at all to it. It'd sqeek for a minute if it was rainy out but after it got going it would stop. Other than that it was great. But Im of the school of thought that anything that can break eventually will and if your belt breaks you're pretty much SOL. If your chain breaks you remove the broken link with a cheap chain breaker, pop a new one in and keep going. No biggie. Plus a chain lets you play with ratios. Theres no one that we are aware of that makes a pulley that will work as an aftermarket part for our beloved savages.
The oil leak sounds like the head plug as verslagen suggested. The fix is well documented and cheap. It just takes a little effort and some RTV. Keep a close eye on the oil level until you get that fixed. My leak was so bad I'd lose about 1mL a mile if I was going anything over 40mph. Overfilling on these machines isnt an issue and that makes oil checks a lot easier. Screw what the manual says, leave the bike on the kickstand on level ground and fill'er up until the oil reaches the bottom line on the window.
