Tire Hitting MRD Can

Hey guys, after riding with the MRD Z-Pro and riding around normally (no jumps), I'm finding tire rub marks on the inner side of the can. It doesn't look too bad, but I was wondering if you guys had the same issue? I'm running a 150 Pilot Road 4 in the back. Thanks.

Is your bike lowered?

Mine rubs but not from normal riding. Stairs ( I call em "urban hillclimbs") and jumps mostly. You can try to shim your exhaust out with some washers. Is your shock really squishy or something?

Haven't found anything to remove the marks yet, might try soda blasting

You probably need to put spacer on the mounting bracket to push it out a little

You wouldnt have that rub if you have a well built exhaust (inside joke) carry on

Sounds like you have a bigger problem if your tire rubs the can from "normal" riding.

1. Is your bike lowered?

2. is it set up for a 110lb person and your 250lbs?

3. How the hell is the even possible with just plain normal street riding?

Stock suspension, I weigh 190. Not lowered either. 


Edit- the suspension seems squishy, though. I'll try to mess with the clickers.

I weigh about 10 lbs less then you with my gear and I ride pretty hard of road and never hit my exhaust. You can shim it out but that's just a band aid I'd say you need some suspension work if it's happening during normal riding.

bike ever been crashed?  bent subframe?


I weight 175 and have had 160 pilot power and pilot road2 and never rubbed on the big stock exhaust.


shim it!

I had that problem, but only because I had the passenger pegs removed and didn't have the mount there. Made a mount, all nice and stiff. I go at it pretty hard and there is no more rubber on my pipe.

Normally, there is over an inch of clearance at full compression of the suspension. Your contact is because either the pipe is installed wrong or the subframe is bent.

Plenty of posts of the MRD rubbing SM tires at full compression, surely we can't all have bent subframes?

You saying you can disconnect the linkage and move the wheel all the way up without touching the exhaust with a 150 rear and Z pro? Because I never could and I know my pipe is mounted correctly and subframe is straight

I've seen SSW race bikes with rub marks, it happens. OP needs his suspension set up properly first and foremost

After comparing a factory sm with the MRD, the other drz had the rub marks even worse and the rider is about 150lbs. He does do some crazy jumps, though. I'm certain than neither of our subframes are bent. For a moment I thought the reason could be that my drz is an S model with 17's, but the above comparison proved that otherwise. I guess there would be more clearance with knobbies on a narrower 18".

for what it;s worth, i have some tire marks on my FMF can from my knobbies(120-100-18 was my biggest i think). But i really put the suspension through its paces so i'm not too worried.

wd40 will take the rubber right off.

Definitely rubbage.  The mid is shimmed so it doesn't rub the frame.  The can is shimmed out the other way.  I'm running a 150 PR3.  If it isn't "slamming" into it I wouldn't worry.  Nothing wrong with a little rub every now and then.  My wheel is centered in the swing arm, and I'm not sure if a real SM is or not.  But mine rubs both sides equally.  As I have a tool tube as well.


Define crashed/bent?  It's a dirt bike I try to rest it equal amounts on both sides....


Just FYI.  DRZ's are not symmetrical.  Wheel centers don't align and they don't align with the frame and the engine is not centered in the frame.  It doesn't really matter.

I run a MRD Z Pro . A 150 pilot power on my Motard wheels and a really big Motoz Tractionator on my dirt wheels . I weighed myself with my gear on and I was at 240 lbs. no tire rub .

      I've read a lot of threads about this but still haven't found exactly what I'm looking for.  I'm pulling my 2004 DRZ400S out of storage sometime this week and getting it ready for the season.  I live at 9,000 ft, but my first ride of the year is probably going to be at around 5,000 ft.  I was going to pull the 145 main jet I'm running and put in the 150 adjusting the needle from the 2 clip to the 3rd, then re-jet once I got home.  I already have the extended fuel mixture screw in place so I started thinking that I should just run the 150 jet set up and adjust the fuel screw to compensate for the higher elevation where I'll be doing most of my riding.  I will be going down in elevation for rides until late May or June depending on snowfall, but riding on the street when I'm able.  Are there any disadvantages with this?
      I'm new to posting on this forum, so please forgive me if I didn't get the right search words in and there is already a post about this.

      Good Morning,
        Last night I measured my valve clearances for the very first time (I know...) on my DRZ400S.  It's a 2002 and I've owned is since 2011.  I bought it with t's got about 15,000 miles on it and most of it's miles these days are on dirt.
      Intake specs are 0.10-0.20 mm.  Exhaust specs are 0.20-0.30
      My intake valve clearances are in spec, forgot to write them down.  My exhaust valve clearances are between 0.1778 and 0.2032 which is slightly out of spec.  They are no more than 25 microns out of spec.  My question is, do I really need to shim these?  Will this kind of out-of-spec cause performance, mechanical, or other losses?  As far as I can tell, I'd have to buy a whole shim kit which is like $80.  Thanks!

      Currently have a 2000 drz400s work stock suspension. From my understanding this is the worst suspension the drz ever came with without even rebound damping adjustment. Therefore I'm looking for a upgrade. I'm seeing three approaches to take. First being a newer year s model suspension with dampening adjustment. A SM model USD forks and triple tree or some USD forks and triple tree from a rmz. So if you were going to upgrade what direction would you go. I currently ride off-road mostly but I do have some 17s for on road with as well so have to keep that in mind. Thanks
