I'm totally jealous....but looking (when the stars and $$$ align) to make the change as well from my butterscotch orange 97 250. (that's a keeper forever though)
I've lurked enough to know a bit
Meca Systems aluminum is an awesome skid plate but the Hyde IS super protective
P3 carbon fiber guard if it's available over the E-line which has cheapened
2K2 you can easily add flywheel weights to if needed so no problem here
2K3 is easy switch but you have to purchase it. Heavy flywheel, 110 watt light output so you can run about anything you want. Nice
RB mods are great and I think he has a needle as well otherwise LT
I think the new GG bikes have an aluminum impeller already (someone will know)
Haven't heard much at all about boiling problems with the GG. KTM 300's yes. With a 2K3 you could easily rig up a fan if you were worried about it.
I would respring/revalve for your weight but heck ride it and see how it is.
BRP radiator guards
EE/Moose are the same thing, Cycra, Fastway all nice. BONZ mounts are slick.
The Moose competition shields (not Evolution) are really nice and SUPER flexible (for crashing) which I like. 2 different profiles as well
From those who have an 08 the seat is much better than the 07 BRICK
G2 throttle cam you might like on a 300
Scotts make a beefy rear disk protector
Chain guide looks wimpy but really does the job from all reports. LT makes a beefier upgrade if you desire
I'm sure others will add more
Good luck with it
