Just to nit-pick...
An earlier question asked if the $ included shipping TO and from.
Of course not, of course. He will ship it back to you, but YOU ship it to HIM.
That's intuitively obvious to a casual observer, but thought I'd mention it anyway.
BTW..he may have this on his website, but DO prepare your carb before shipping. Maybe chip off some of the crud? (Clean would be nice) NO hoses.
You might even make sure there isn't any fuel sloshing around. Really! ;)
Another btw...don't fail to ship the slide of course. Just 'cuz you might want to leave it attached or something? You have to send that in to be machined. Guess he could just SELL you a #7. That way, you can 'spearmint with different slides.
Here's a thought. Have him cut your slide to a #6, and buy a #7! You'll find the #6 useful with needles as....oh, say a BEM if you want to tone your bike down from one'a these 4th gear wheelie machines we all been readin' about!
Yeah. Right.
Cheers!
