Hi guys,
Im just new to vital so i hope i do this right but i have a question for all.

Im restoring a 89 Rm250 and have always been a big fan of pro circuit products but they don't make pipe and muffler combos for the 89 model, what i was wondering if anyone knows if 1990 Rm250 pipe and muffler combo will fit?
Im sure they both use the same cylinder, i know the 89 has a mount that comes off the frame above the kick starter that changes postition on the 90 but that doest bother me to much.
Cheers peeps

I would search pictures of the two bikes to compare differences, if possible. (It sounds like you already did)

Did you call pro circuit to find out they don't offer the pipe for the 89 model? Where did you get that info? I've heard they will make pipes special order. If anything, maybe you can send them your stock pipe so they can replicate the mounting points.

I think I ran a PC silencer on a stock pipe. That was recommended by Suzuki Country Racing way back when they made really fast bikes. The key bored carb made that bike feel ported. It was a huge difference with just that. I also ran a Stealhy FWW. That was a really good bike for me.

I ran a '89 PC pipe and silencer (got a good deal on them) on my '90 250 back in the day.......I don't remember any issues with that setup. Should work the other way as well.

Post some pics of your bike.

Making pipes special order is a mixed proposition. I've only heard of one guy here getting a special order pipe, everyone else who has tried has been told not available, or, you need to buy a run of the pipes for PC to do it. I'd say on a bike 25 years old that is not a Honda, a special order pipe is not going to be cheap or easy. And sending PC a pipe from Australia to use as a go-by isn't going to be gentle on shipping costs I would guess.

^ This. SCR was very well known at the time for hot RMs. I'd try to duplicate this set-up if this was my bike. PC pipes look cool and all when you can get a raw finish one, but they aren't necessarily better than stock 100% of the time. They are good at moving the powerband around, but not necessarily making better power, esp if the motor hasn't been modded.. Just my .02

I didn't call pro circuit to find out this info but I've received the same reply from 3 major U.S stores that sell a lot of pro circuit pipes.
Im from OZ so sending my pipe to PC is out of the question.

Cheers

I would run the standard pipe but its condition is not the best so thats the main reason for replacement.
Ive also been told to run a 93-95 RM250 carb on my 89 and that'll also make a huge difference.

Thanks

This is exactly what i wanted to hear..
I know someone that tried a 91 and that didn't fit so fingers crossed a 90 fits..

Pics will be posted when i get a little further into the project..

Thanks barkhard696, i totally agree. The main reason i wanted to replace the pipe is as its slightly damaged and the rest of the bike will look top notch so i don't want a dented up pipe spoiling my masterpiece..
Thanks for your .02.

cheers

Another place you may want to try is JEMCO Exhaust in Houston, Texas. Jon Easton Manufacturing Company. He handmakes semi-cone section pipes for all kinds of bikes and the price is about what a PC pipe would cost. It's worth looking into, I have one of his pipes on my '82 RM250 and it's really cool. Jon has been making pipes since the late 1960s, it's a small shop and I'd been recently reminded about him having pipes for late 80s/early 90s bikes.

Sounds like your project will be a beauty!

No kidding! Wow, I remember them from the old days. AWESOME call, I will definitely be using their pipes on a couple of my bikes. Good stuff and thanks Jack!!

They where selling silencers for 50 $ a few weeks back , I think he had it posted on off road series that they have some involvement in , it's kind off a hybrid MX / off road race upstate ny, I used his pipes for many years and always was top notch quality
