red barron are very good ,check oz50's prices on the spokes
,if i had a rather slim price budget this is what i would go
Red barron 12" spoke kit from oz50 ,to lace them just take 1 spoke out of the wheel at a time replacing the stock spoke with a red barron spoke and nipple (repeat proces to you have the wheel fully spoked with red barron spokes)
2)REAR SHOCK: I would buy a top of the line fast ace shock of the bay as the price of a new redbarron spring alone is worth the price of this fastace unit
eBay Australia: Genuine FASTACE Rear Shock Model BS-66AR-280L Thumpstar (item 230145225638, end time 24-Jun-07 20:35:31 AEST)
3)Get the red barron foot peg mount and run some ebay billet pegs ,just search :foot pegs or footpegs consistantly and you should be able to hook some up for around $50 which is $70 cheaper than the redbarron ones
4)Front suspension: replace the oil with shell 20wt or thicker oil ,take out your springs take em to your nearest 50s shop or shop that sells good! brands ,no cheap ebay **** here and get some stiffer sx springs ,not 100% sure if the red barron ones will fit you may have to get the springs out of the factory fork
5)GET SOME DECENT BARS ,if you have not replaced these yet and you do freestyle your gonna eat **** bigtime so replace the stockers with some pro taper xr50 bend bars at $84.95
6)Depending on how granrly the top of the landing is on the jump you may wanna replace your bashplate to somethiung with a bit more strenght here, get the older style ones not the bbr type i would go a sano or five o one to same your engine
7)brace the frame ,its a must other wise your really pushin ya luck.
