You can skip the vacuum line when you go Raptor, as it is a traditional manual petcock. I use standard braid cored fuel line on my bikes, change it once a year. Modern fuel erodes the inside of soft lines, plugging up the fuel filter and/or the petcock. I run a right side petcock, about a foot of fuel line, with a metal filter in the middle. Couple bucks a year to keep fresh fuel lines on it is money well spent.

Probably a better grade of fuel line than the cheap crap put on newer equipment.

I put fuel in a 2 year old gas powered weed eater last week, watched it all come out the fuel line holes in the tank. Lines looked okay on the outside, had rotted off flush with the tank base inside.

I do have some ethanol safe lines to replace the factory ones. When/if I get around to it. Have two string trimmers with wheels, not sure I'll bother fixing the handlebars and shoulder strap one.

Same principle as when a riding mower deck gives up the ghost, I've got a 12 foot cut finishing mower behind a John Deere 2350 diesel farm tractor, why waste money on the little 42 inch cut versions. The little finishing mower is a 60 inch cut.

My petcock died a while back.  All stock except the dyna muff.  But, it's 26 years old.  That's a long time for a little rubber diaphram.

My '06 was stock when I put the raptor on...first mod I did...in the mornings when it was cold I'd roll up to a light and it would die...hasn't done that since the raptor...

easy fix...maybe 1hr if you go real slow...and solves a ton of weird/strange symtoms that are very hard to diagnose if you don't know the vac petcock is a failure point (i.e. most dealership mechanics).

Verslavy is a must have to keep your engine from getting torn up when the camchain stretches too far, plus it gives you an indication that your cam chain will need replacment when the time comes.
Harder to install but still can be down by your average Joe w/o a problem...

Those 2 items and regular oil changes, setting idle correctly and keeping a good tire pressure should get you way down the road for many years
