With the stainless scourers in there it allows the muffler to soak up some of the noise & it still sounds quite deep & has a nice note

I basically slide the stainless scourers over the new stainless baffle tube with enough to cover the full length then cut some sheet muffler packing the right width (same length as the muffler) then rolled it around the stainless scourers & slid it all back together

Next time I might pack it a bit tighter though but it is great the way it is, Nice to have a new stainless exhaust from front to back on a 20 year old bike

Any pics of your XR G94 with the White Brothers muffler? Not many of them around anymore so it would be nice to see
I'll have to give the steel wool a try. I agree that lowering the amount of discs significantly reduces performance. I also got rid of the original packing ASAP and put in much fluffier stuff. I tried a couple different packing styles. That did help get rid of some of the ringy sound of the exhaust but the bike can still be heard from a couple streets away.

When I tried 4 discs I could barely even get the bike to start... And there was no torque, just a very ringy and sharp exhaust note that I didn't like at all. Now I am using 6 because it's the least amount I can use without ruining the performance entirely.

I can't take a picture right now but here's my latest ride on the beast!

nOOb question

I'm thinking about cleaning the carb. Being that the bike 10 years old, probably should replace some old stuff in the process.

Can someone provide me a laundry list of what parts I should consider getting if I do pull the carb and clean it?

Thanks!!

I'd leave the carb alone if the bike is running good. As long as the bike is ridden and not left to sit for extended periods, the carburetor will stay in good shape.

Is it hard to start or run crap when you turn the choke off? Does it have a flat spot/hesitation when you accelerate?

If not I would leave it then

Hi guys, just checking in after months of lurking in the shadows. I am now the proud owner of one of very few Honda XR250R's in South Africa. For some reason they never imported many of them. I'm going to do a rebuild and I know that spares are going to be a tricky thing to find here so I'm hoping to be able to draw from the collective experience of all those who have walked this road before.

Wish me luck as i try to take this.....



Back to this...



Hopefully you can follow the re-build here. Any and all advice is welcomed..

Sounds like I'll leave the carb alone then. I had a mechanic friend look it over yesterday and he said it performs like an XR250R. I've had a couple of guys ride the bike and all say the throttle response was disappointing so I've been scratching my head wondering what I could do to improve it.

Yea, the 250 can leave more to the imagination, but XR's are known for their tractor likeness. Your buddies are probably used to more high strung 250s. Don't worry, that XR will still be chugging long after the other 250s of its time.

An edelbrock, airbox mod, and exhaust mod made a real noticeable difference in my bike. Probably have a hard time finding an eddie for it, but I believe Mikuni is still popping out pumpers for it.

As with this type of problem, since it's not consistent, actually rare, it becomes a guessing game of what could be wrong.

I just started working on bikes about 3 years ago, so my experience level is very low but wanted to get other's thoughts on how you might approach the problem.

Any help is greatly appreciated!!
I know it's unlikely that this is your problem, but way way back when my XR was still a turd fresh out of the previous owner, a combination of a tired cam chain, a broken cam chain tensioner, and jacked up valve clearances would make the bike randomly die as you describe. Like everything would be fine and then oh no it's dying again every once in a while, and you couldn't stop it from dying by playing with the throttle.

Just one of my very strange experiences with my XR250R.

Check the easy stuff first. Check all of your wiring for loose/corroded connections, make sure your kill switch is working properly, valve clearances should be within spec. etc...

I'm going to put my FMF Powercore 4 up for sale in the flea market. I changed it in short order for a Quietcore. My old ears didn't like the sound level!

I hear a lot of people change from the powercore to the quietcore. Any comparison on the powercore to an uncorked stock muffler?

For me, the uncorked stock muffler had an irritating pitch. The Powercore's pitch was fine, just more volume than I liked.

Anyone interested in a Devol skid plate for a '96+ 250R? I sold the bike a while back and this is just sitting around. $75 shipped to your door.

If timing was right I'd probably snatch that right up to compare with what I currently have. Unfortunately my tuition is due on the 15th so I'm broke for now

Bummer,

I was in Hawthorne in the middle of April. Met a nice lady at the airport, Betty Easley.
