i have received my 115 and 112 jets i know how to fit them where they go and how to take off the carbs but is all i do just take the old ones out and replace them? or is there othere settings like piolet screws i should know about

While you've got the carbs off, it wouldn't hurt to give them a once over. It's worth cleaning the emulsion tubes (main jet holders), pilot jets (you should be able to see light through them) and checking the float heights (12.5 mm). Carb cleaner will do the trick. Lock wire or fuse wire is handy for the cleaning the pilots and emulsion tubes too.

You're right in thinking you should check the pilot screws, particularly with your exhaust: set them at 1 5/8 turns out to start with (stock). Try them, and if it feels a little sluggish down low, screw them in 1/4 of a turn and try them again, etc. It's trial and error really, so try not to change too much at once before you take her for a spin

how do i check the float heights...

I think the rvf floats are a 1 piece plastic job so they're not really adjustable.

You really need a Haynes manual

Once you have the float bowls off, you need hold the carbs on an angle (or support them on something) so that the float needle is just seated (but not fully seated). Measure the distance from the carb (where the float bowl bolts on) to the upper-most part of the float with a ruler. If they're out, you need to remove the float and bend the little tab to get the right height. Hard to explain without pics, but you'll probably get the idea when you have a look - only takes about 10 minutes.

But seriously, you need to get a Haynes manual

Ok ill give it a shot is that 12.5mm for standard nc35s does it make a difference if i have a maggot?

Also quick question what is the best oil to use i am in australia so if anyone knows the best available please let me know and also changing oil and petrol filters how do you know when it needs a change....my oil is a little dark so i am changing it

You probably want to find yourself a 10/50 or 20/50 due to the high ambient temperature in Aus ?

No difference.

I'd suggest 10w 50 semi-synthetic oil.

omfg i just realised i orderd 1x115 and 1x112 jets insted of 2 of each what an idiot soooo pisse of right now
