Just bought stock 04 CR250R Pipe

[2005CRF450RKID]

Yea I just bought a stock pipe finally got a good deal on it.? I was thinking of sanding it down to look more like a works pipe. Is this a good idea? What should I do or use to do so. I heard the stock pipe for the 04 was one of the best pipes instead of paying a lot for an aftermarket is this true?

if you could take it to a sand blaster that would be easier but yeah sanding it down would look nice dont use to much of a coarse sand paper though

If im going from a Pro Circuit Platinum 2 pipe to the Stock what differences would id be looking at? Also Ill prob still have my Pro Circuit R304 Shorty Silencer still on it. Any details appreciated!

No stock pipe is better performance wise.

[cr125josh]

you would probably looking at maybe a little power loss all over the powerband more noticeable down low though some gearing changes could fix that though. Why would you down grade from a pc pipe to a stock pipe?

[2005CRF450RKID]

Because the Platinum 2 pipe is for low end and its dented. I also heard from alot of people that the stock pipes on the 02-04 cr250s are really good, believe me i wish i could get a doma pipe or a sst but i dont got that cash. If i could find a doma pipe for my bike id get the money some how even if i have flip the convenient store haha jp

Stock pipe works great ont he 04, especially with the procircuit shorty silencer. Jsut get some med sand paper and that thing will shine up in no time. Hit it with a brillo pad occasionally between rides and it will look sweet..

Nice job sanding that down where that line is on the pipe I might have to copy you!

If jetted right you should notice a broader rpm range. The PC shorty should give a little more off the bottom vs. the stock silencer. Try paint striper on the pipe first so you dont put sand marks with an agressive grit. Afterwards you can use a red scotch brite pad with wd to keep it from rusting after every ride.

Yea my exhaust flange came in from Topar Racing http://store.toparracing.com/merchant2/merchant.mvc?Screen=PROD&Store_Code=TPR&Product_Code=CREF-01&Category_Code=HON It fits well and every thing but I think my pipe is tweaked or something it definitely doesn't leak as bad as before but it still does have a little leak where the last gasket is near the cylinder on the exhaust valve has a little piece of the gasket poking out. The pipe wont go on like flush it has to be a little bit crooked on the flange is this normal???

[2005CRF450RKID]

Anyone know anything? You think this small exhaust leak will effect the power?? Still waiting on the stock pipe hopefully that fits flush.

Its normal but i usually fix it because i want a tight seal and don't want spludge all over the front of my bike but that link covers how to fix it.

Stock pipes seem to be hard to find. I have two stock pipes for my 02. When I do see pipes for sale, the sellers want load of money for them. I've tried the aftermarket pipes and I prefer the stock over the others, for my kind of riding.

[2005CRF450RKID]

O man I'm about to cry the stock pipe isnt lining up with the PC Shorty Silencer. Stock Pipe is fine silencer is fine why is this! The silencer wont reach the pipe by like a 1/4 inch but the rubber clamp that goes over it is holding it on for now any suggestions??

[H4L]

Did you loosen the hangers from the frame that bolt up to the pipe & silencer ? Fit the pipe & silencer together then adjust the hangers in place & tighten the bolts. Also check to make sure the tabs on the pipe or silencer aren't tweaked. Hope this helps.

[2005CRF450RKID]

Took A little fabrication but i got the Stock pipe to Fit with The PC Shorty

Yea look in the garage those pics didn't work right. I like the stock pipe way better then the platinum 2 pipe, Feels a lot better!
