300ex rear end and motor work

[ride300exrider]

i have a 300ex that is in great shape whit lots of work done to it i just cant seem to get the price im looking to sell it for so i think im going to build it into a full out race bike i know a 300ex wil never be a "full" out race bike but im going to build one mean 300ex.
the only thinga lest to do realy is a rear end with shock, im not sure what to put on for that i want to spend most of my money on the motor and not so much the rear end but it has to be able to jump good. i just what to here what u guys think i should do and where i should get it from.
also i am going to get the motor all done out not dure if i should do a 330 kit or bigger looking at the pro fab 385 kit which is new. i would like to know what most people are running and what u think i should do.
i just want to have a fast rideably 300ex that will eat up 400ex's and maybe piped 400ex's
also want to know if a 400ex carb would be good for the bike after it is built up? and i need a new rear axle. whixh is better ???? dualblue or lonestar

sorry for it being so long just want to get the best stuff for my honda
thanks ed

for a rear shock every one says a 01 raptor shock with a 400ex or 250r sping on it. for axles stay away from durabreak and go with lonestar. if u dont have a aftermarket bearing carrier u should pick on up 2. i have a RAD-mfg an couldint be happier.

for motor work im getting a gt thunder 350 kit soon. get some pics of your quad or racing pics. i had a nasty crash last nite in my race but i still got first overal:devil:

Rear end...

Burgard +2 swingarm, Lonestar axle, Lonestar bearing carrier, Raptor rear shock, and a good set of chain/sprockets...

Engine...

Contact GT Thunder or Curtis Sparks, they do good chit for a 300ex..

Carburator...

Check out the Mikuni Flatslide..

[roostin_dale]

BTW..if your doing the whole rear end..look into a Wave rotor and a braided brake line..

[ride300exrider]

do or should i get a 400ex spring for the raptor shock and does it need to be valved for the plus 2 swing arm?
thanks guy
looks like gt thunder is the main pic so far

[roostin_dale]

I believe the 400ex spring is for lighter riders? I have a raptor spring and I weigh about 175 or 180.

Just make it a little stiffer for the +2 swingarm..

[ride300exrider]

well im only 150 so i might do the lighter spring

any other ideas anyone?

GThunder is the way to go, ask laz. about the 350 big bore in my bike, it flies, seems really reliable too.

i like a plus 1 swingy my self, and the raptor spring should be ok for you if your 150 lbs. the 400 spring is for really light ridders like me, at 130 lbs.

also, i have the 400ex carb, no probs so far

i had a lonsestar carrier in my old 300 and it was fine but the rad is good too.

WEll I just have a home built job LOL, but I just started running the 400 carb & LOVE IT!! Haven't had any issues so far it compliments the porting or vise versa ;) I was keeping up w/ piped 400's this weekend :blah:

[ride300exrider]

any other ideas???

will a .080 over pisten, port and polish, a 400ex carb and a web cam make any difference just to keep the cost down or will a 330/50 kit blow that away? also will i notice a different with the .080 over and other stuff?
thanks ed

[ride300exrider]

i race with 400exs and so on and am just trying to keep up with them on strights and has somewhat the same power outta turns, u know what i mean

[bradley300]

a 350 will embarass an 80 over motor:devil:
