Check the tech section for the oil change frequency which is actually about 3726 miles or probably about 4000 miles in the handbook. The filter should be done at the same time. At the risk of offending you and others, enjoy the bike stock for a couple of months before you decide on exhaust mods. The one weakness of this great institution is that you may end up with information overload. It's likely you will have to rejet your carburettor once you have decided upon the type of exhaust you want to use. There is good info on how to do the oil change and filter in the tech section. The preferred oil for Americans is Shell Rotella because of it's relatively high ZDDP content which protects your valve lifters and you should consider the Yamaha Raptor petcock modification.

I'd also say do the exhaust and carb re-jetting at the same time. It will need re-jetting, especially if you change the exhaust.  Definitely the Raptor petcock. If you plan on doing any of your own maintenance (like adjusting valves) you'll want the Raptor for sure, not only is it a better petcock, the tank comes off REALLY easy with it.

Don't know about the rejet - there are others on here with more knowledge about than than me - but be aware that turning the idle mix screw in or out only affects the mixture when the the throttle is closed or almost closed. If whatever airbox, exhaust mods you do require a jet change that screw is not going to do much.

Thank you!
I just ordered a dealer take off dyna p/n 65747-94 for $38 shipped

I have a buddy who has a welder and am going to mess around with it once it comes in.

I dont mind spending a few extra bucks on a actual K&N airfilter since it'll do the job correctly, I'm going to wait on the filter but will be looking into that next

After I mount the muffler I'll see how it runs, if it feels like it needs a rejet then which rejet kit is best?

Should I do the filter before I rejet since the K&N will also free up some air coming in?


I'll get back with pictures and maybe a video of the results

Thanks, im in Ny on Longisland which is 400 ft above sea level so 150 main jet should be good?

Should I be doing anything to the needle spacer? Replace it with a #4 washer or anything?

I haven't taken the tank off and carb. yet and don't wan't to do it several times

I'll try stock after I get it fitted and we'll play from there

Thanks, I have done plenty of reading about everything

I'm waiting for my dyna muffler come in and then I'll do some disassembling and mounting, after I start the bike I'll look around dealerships if I need to get the main jet

Thanks all for the help, if I am able to get a bend tube cut for myself I will get more made and we'll start a sale on here, how much could they go for $25 shipped for regular pipe bent sound fair?

I just did a dyna muff this year and am also on Long Island and had good results going to a 152.5 jet withabout 2.5 turns out on the mix. I did make up an adapter between header and dyna. I did not change the stock air filter.
