So yeah let me know what you think.

Im going to do the powroll 12.2 stroker,and a **** load of motor work,asr a arms,g force axle,lengthen swing arm,450r shocks,ect.

[Cmh156]

Well im thinking murdered out with red hmf and red hubs?

Will post pics of the build once it starts,always got the teardown,sell stock parts,save buy aftermarket. :)

Ill be selling the stock a arms,axle,pipe,and other **** too.

Let me know if you got any cheaper aftermarket parts also.

looking good,theres lots of things you can do to that,i've had 2 87 250x's,one i still have is my keeper,and i love it.
FST(FourStrokeTech) makes a 390kit,you should look into that,that would be sick.
for exhausts,HMF is good,Whitebros,Supertrapp,Yoshimura,and FMF.
DO NOT GET A COBRA OR A DG,they sound like crap IMHO,i had a DG on my first 250x,hated it,and sold the exhaust and got an FMF,and was much happier.
anyways,goodluck with your build.

Im getting a HMF>

[Cmh156]

Well getting a scopion header mailed to me here soon,picking up a 95 or 93 300ex that im going to sell to fund this,and ripping motor out tonight,some pics may be up.

[Cmh156]

Scorpion header that is. Motors last bolt by the swingarm on the bottom stripped so i have to cut it,and than motor will be out.

[Cmh156]

A bolt is stripped out so i gotta cut it out,scorpion header on the way and looking at a new fmf seat cover for like 25 bucks,

Build going to start very very soon.

[Cmh156]

Man you guys arent very active on here are you?

Hahaha i was hoping to get some ideas from you guys on here.

[m0t0xk1d]

ha we used to be now that school started it has died down.


i would start off with suspension. jb relocator and good aftermarket 400ex shocks with 400ex +3 a arms.

[born2ride14]

post pictures, plus you havent said what you want

[Cmh156]

m0t0xk1d- Im thinking +1 or +2 cause i still want to ride on the trails also. And im getting either elkas or works,depends on how much money i have.

300mainiac- I posted some pics of how it looked,i forgot to take pics of it as im tearing it down right now. Will get some.

[Tommy Warren]

if your doing 450r shocks you might as well get the 450r swingarm since your extending your swingarm anyways. it takes a little modding to get it on but nothing major.

[Cmh156]

Well im probably just going to extend my current swingarm since i know how to weld and have access to the supplies.

+2 longer
+2 wider in front
+3 wider in back

Sound good?

[907Rider]

Yo chris looking forward to seeing this done. This place hasn't been vary active for a long time... but theres lots of info to be found just gotta use the search button.

[m0t0xk1d]

you will want the front wider then the back. yyou want this becuase you can corner faster as in ride harder into the corners and come out fast with the rear end wider the rear will slide out from underneath you a lot more with the rear wider. for front i would go with 450r for cheap.

[Cmh156]

Well heres some pics. My cameras settings were off so the pics are fuzzy,will get better ones this week or weekend.

Excuse the mess my tools spilled and my camera was dying so i snapped some pics.

Still gotta take some stuff off but its almost bare.

Poor motor,i dont think the guy before me cared about it,i rode it 3-5 times before the clutch went and look at the internals,looks like the cam and rockers are GONE.

http://i285.photobucket.com/albums/ll71/chrisiscool666/bmx007.jpg

You can see how worn down the one rocker is and the same side of the cam is too.

Messy work bench,had it cleaned but i was rushing.

Let me know guys,im going to race in the jr woodsman class this summer so it will be epic,here are some mods i plan on,my mind changed and i like were its going.

+3 +1 full flight a arms.
450 shocks revalved by gt thunder.
Black fullbores.
G force axle.
ITP Beadlocks in black.
HMF in red.
Stage 3 cam,oversized valves,wiseco piston,port and polish,all that good stuff running on VP-110.
Swing arm from a 450r or lengthen my stock one.
Red silencer,hubs,and maybe other tiny things,mostly black.
Holeshot xcr's.
400ex carb.
Pro peg nerfs.

You get the flow.

[dns1764]

take a lot of picture of the build. good luck

[roadthrills]

I'll be watching this build. Here is mine-->http://www.exriders.com/vbb/showthread.php?s=&threadid=324237 It has gobs more power now, and the +3" swingarm is just right.

[shiley55]

i reguards to your wanteing to extend the swingarm yourself i would not recomend that becasue it will change the geometry of your suspension and you might not want that you would probley be better to just find a used 450r swing arm and put it under your quad also i agree with +1 in the front and if its with 400ex a-arms then its gonna be like +2.4 or something i dont know the exact measurements but i dont thik alot of ppl on here were sugesting anything cause it seems like you already have your mind made up on what you want to do lol but it sounds like it will be a good build cant wait to see it . also are you gonna bore it or stroke it with any of the powroll kits i really want to do there 350 stroker with 12.2 piston and see how long it would hold up in hairscrambles

[atvnut22]
