How big to bore TB?

Guys and gals, I have a couple of questions.

1.  With my engine mods, would a bored throttle body help or hurt?
     a.  11:1 Wiseco piston
     b.  Raptor stage 1 cam
     c.  Muzzy exhaust
     d.  MSD FI

2.  If there is a performance gain, would it be at the upper end, or would it be through out the rpm range?

3.  How large should I bore it?  I'm a machinist and have a lathe in my garage.

4.  Will I have to have new maps?

5.  If I'll need new maps, do any of you guys have what I'll need?

man you got some serious parts...nice bike...how does it run?

Thanks.

It runs pretty good.  It'll do 45mph in low and 62mph in high with the 26" Bighorns.  When I had the stock 25" tires on it, it would hit 65mph with two adults in the seats.  The throttle response is instant and it'll pull hard to about 57mph.  In low, it'll bang the 8K rev limit @ 45mph pretty darned quick.

What I really want now is mid travel.  I'd like to get rid of the spacers and improve the ride a bit.

yep the travel makes it a whole new machine, you don't get beat up as much. I went the opposite route you did, I need motor now...but till she blows I don't wanna open her up, its never failed me yet

JP,

You've got a nice lookin' rhino, no doubt.  I'd love to have long travel, I'd bet that the ride is as smooth as silk, but the woods and trails here just wouldn't allow it.
