what else to go w/ bigbore

[tx_250r]

i'm helping my brother put a esr480 big bore on his 04 450r we will send it to neil @ c-leigh for port work and install a cam and jet kit. any opinions on what cam to go with??? also what else should we do while we have the motor apart??? he already has a full hmf exhuast and uni filter.

im not sure about the cams out there. but i run hottcam stage 2 and it made a hell of a differance on my bike. but it depends where you want your power to be. the stage 2 puts it at mid to high. but that where i wanted it. and im going to run it in my 500 kit.:macho

yeah the r has plenty of bottom so mid to high something for drags but also fun in the woods. who makes the 500 and how much is it??

[tx_250r]

what other big bore would you guys suggest looking into?? has any one tried the esr big bore? how about the ahtena kits on ebay for $600??

The ESR kits are very nice. 480cc at around 12.5:1 with a 3-ringer Wiseco....great reliability.

DASA also makes a nice big bore kit. 12:1 500cc.

I believe the Athena kit is only 10.7:1 at 480cc.

i wonder why esr doesn't have the 480 big bore on their web site?? thats more than likely what we will get but i will chaeck out dasa. And after esr gave me the run around on my act250r pipe and had me waiting for at least a month i really would like to go some where else but then again... i do like their products.
