Just bought my REV-MO Muffler

[kz6fittycent]

I'm pretty stoked about it. Got a small bonus from work and decided to pull the trigger on a pipe as my stock one is jank. I looked at others and whereas they might be "better", I just didn't have the cashola to get one. In any case, I bought the "raw" version, which isn't polished - I prefer that look over "shiny" stuff. Sent the request for the tune, too. Should be here sometime next week and then I'll get to work installing it.

Anyone else have it installed? Were there any gotchas?

1/2 a beer job. EZ and fun. The hardest part is taking off your stock one, lol.

Yeah, that rear bracket looks a "little" involved but I'm certain I'll be fine. At the end of the day, it's all just nuts and bolts.

I will add that getting the "companion tune" from Rev-Mo isn't as smooth a process as you'd think. Dude has like 10000000000 questions about the current state of the bike and I've had to answer all his queries - now he's gone dark. I have NO idea if I'm gonna get a freakin' tune. Sheesh. Not the kind of experience customers really like, ya know?

When did you order your exhaust/tune? Today? Yesterday? I'd give it a little time. I'm sure the tuning wizards there are using your answers to their million-point questionnaire to brew the perfect tune for your specific bike. Worse comes to worst, shoot them an email; "Hey man, was just wondering when I'll be getting my tune." They're a (relatively) small shop. Gotta give 'em a little benefit of the doubt.

IMO, I would answer all their questions as honestly as you can, I'm sure they're not asking just for the heck of it.

I bet they deal with the same thing we get here all the time. "My bike didn't run well, and after my free tune, it still doesn't! Now it's YOUR fault!! Whaaaa!"

I picked up the xb-sg and a baro sensor last spring. Sounds great, imho better than a repacked jardine rt1. Tuning has been an iterative process, he has been very supportive and responsive. He may selectively answer questions, but has always been helpful and right. Test your intake seals after the motor is hot.

Yeah I've done that, and we're good there. My existing muffler is pretty rough and "flaps" when it's hot (just off long ride down the interstate). Kind of hard to explain. In any case, once it's replaced, I'll need that tune to at least start from somewhere that's closer than the stock tune. There's definitely some internal damage to the muffler which is lending to the odd noise. Bike runs fine otherwise.

P.S. The headers are sealing, too. He asked about that, as well.

I gotta ask What is a ( REV-MO Muffler ) am I outta the loop here ?

Used to be "BuellTooth" website - I guess they're rebranded now.

Thank you !

So if my bike has an old Jardine RT-one can, and is tuned to it, can I just straight swap it for these? Same mounting brackets etc.

I need to replace my Jardine, and any I can find right now are almost 700 CAD.

Previous owner welded the end caps on instead of just using proper rivets that would last when he last packed it. Now the packings burnt up and the outside body is rusting badly.

 

[Cooter]

You can swap it. The Rev-Mo comes with any brackets you need to mount it to the bike. Heck, the tune will probably be fine too.

Allegedly mine was bored out to 1350 or so CC by the previous owner (he made the claim with nothing to back it up). So if there is a smidge of truth to it, and it was tuned with the oversized bore, then I'd just leave the tune be.

The engine options are typically 1200, 1250, 1275, 1442(88") 1475 (90"). So odds are its either a 1250 or 88". Granted that there is a 200cc span between the two, you really need to know what you are working with to get a correct tune.

Its probably a 1250 as thats just an easy drop in kit, and the 88" kit requires splitting the case, machine work, and will likely have cams and other work done to work with the increased displacement. I've never heard of a 1350 before, but I'd also never heard of an 1170 until magnesium mike created the beast.

The takeaway is that if you are concerned about a correct tune, you really need to know what the engine specifics are.

 

[Cooter]

Thats what I meant. Your existing tune. If it runs well now, it should run well with the Rev-Mo muffler as well. So leave the tune alone. IMO.

I doubt the flow characteristics of the Jardine are much different than the Rev-Mo.

He claimed it was a custom bore size and not a kit. But like I said, I haven't been able to physically confirm that and the shop he said tuned it he wasn't able to provide the name or dyno sheets of. So I took it with a grain of salt that its just a 1200cc. I will update my own thread once the engine is apart and measured and I find it to be a custom bore size. IT wasn't really running right anyhow and I just had injectors cleaned and installed a day before my motor vehicle accident Sept. 3rd. Haven't ridden since and likely wont any more this year. so my butt dyno is not working either. Ok, sorry about jacking the thread.

Hmmm - this ain't right

I've contacted rev-mo. Hopefully they're cool about this. I'm sure he's gonna say that my header is bent or something...it's not.

Kit was missing the aluminum spacers that were supposed to come with it. Anyway, I was really hoping to have my bike on the road tomorrow and I'm disappointed that isn't gonna happen.

See photos. Included a shot of the stock exhaust to show it wasn't bent or something odd. What models had the active exhaust? This one definitely doesn't.

Xb9’s didn’t come with the valve.

As far as the rev mo exhaust goes, I don’t know.
