714's 08 CRF250-500 Conversion
First, let me thank Bob, Roosty, Dogger and 87CR500 for all of the tips, answers and advice. I had been looking at doing this for about 2 years and can honestly say, without this site, I may not have actually done it.
I started off by picking up a mint (12hour) 2008 CRF250 that already had RG3 suspension work for my weight and speed. I stripped the engine out of the chassis and sold it to a guy on ProRide in less than a day..woo-whoo.
Then the project sat for a good 3 months as I gathered parts, bought an engine and contemplated how I was going to start. I had read Bobs build post a billion times and by asking questions became connected to some very good dudes on here.
Grabbed the sawzall and snip snip... Y was out

Next step was cleaning up all of the pocket and getting Y ready

My downtube was easy to get out. There was a visable line around the pocket except for 2 weld penetrations front and back. I took a chisel and gave the little weld a quick tap and it was loose
[/img
next I filed the edge and the downtube piece came right out

Then the bike sat and sat and sat..... wondering where I was going to get a decent welder. I have pretty decent fab skills, but since I moved here a year ago, no connection to a decent welder.

I figured I would slide the 500 in and see how it looked

good carb clearance

While I was on the site I made contact with a hoon here in San Antonio. CR500 (Tony) was at the same stage in his build, so we have bounced ideas, drank beer and pondered the ins and outs of the Aliso Bob way or the full cradle.
Tony had moved his Y, made the new tube and I was about to follow suit when I met Dogger. Great guy from Illinois, does nice work and made me a deal I couldnt refuse...lol
I had a bunch of work travel, Cancun etc, etc... all kinds of reasons to not get er done, so I sent the frame north.
I just got it back and will let ya know how it goes.
Here is his work.[img[/img]

Ok.. So a little more progress. I have decided that I am going to run a single outlet head. My head had the stock outlets pretty messed up, so I removed them in preparation to run 1.
I ordered a stock CRF250 outlet elbow for $14.00 and sniped the ear off

Once trimmed and filed, i checked orientation and will mount it like this

I have a stock pipe, and an FMF muffler to use, but really like the natural finish of the PC works pipe. Its going to be a moto only bike so Im not terribly worried about the damage the offroad guys get. What is the PC pipe like performance wise? It looks like it is a copy of the stocker to a certain extent?? Is it a little more of an RPM pipe?

Which FMF? And there is a big diff between the Gnarly and the PC..britincali wrote:I dint notice any difference at all between the procircuit and FMF.
In fact the only pipe I can tell a diff with is the noleen on my nitrous bike.
The CR500 is an acquired taste. If you don't like it, acquire some taste...
Thanks for the compliments guys. If it wasnt for Banned I would never had the opportunity to see so many other builds.
Im still looking for info on the PC pipe in relation to a stocker. Like I said, it will be an MX only bike. .... Guess Ill burn a few hundred and get the pipe! then let ya know what I think.
