Can any of you guys who've already gone the big-bore route tell me what kind of milage you're getting out of your rear tyres, & any increase in fuel consumption, since you did it?
I haven't noticed much of an increase in rear tyre wear from my Thunderbike performance kit, but the fuel range suffers a bit if I'm on the throttle a lot.
Also, what would be the best kit for a 270 motor? Has anybody else done it to a Scram? Or planning to? I'd love to hear your thoughts.

How many miles do you have on your Scrambler? I had 52k miles on my Bonnie when I wrecked it. There are plenty of others that are at or above 70 & 80k miles... So don't be so sure that a rebuild is right around the corner...
Also, you have an 865 cc motor... the 904 kit isn't going to add a whole lot... Especially if the rest of the intake/exhaust side of things are pretty much stock...
airbox elimination kit, port/polish the heads, open exhaust, cams... that will make the most performance difference...
