First off, those sound FANTASTIC! And for black pipes (black? On a motorcycle? never heard of such a thing everytime-always-everyone-and-their-brother jk man) they look pretty sharp!

Second, you're not getting popping because you are actually idling within spec! Good for you! I've bumped into a few guys with 900's now with aftermarket pipes dealing with popping. A couple of them I was able to convince to raise their idle back up to spec from the super-ultra-low (sounds good, but, it's not gettin' the oil where it needs to be) idle, and the popping went away!

I temporarily mounted an automotive tach to my bike (rigged it up just to work for a ride, wasn't waterproof or anything so I didn't spend any time getting it permanent). I found that below about 800 rpms I got serious decel popping. My theory is, the position of the throttle plate when you close the throttle but are still coasting doesn't allow the air/fuel mixture to be where it's supposed to be, causing the popping. The computer assumed the throttle is open to 950-1050 RPM's, when in fact it's only open to about 800 (or less) RPM's. I have mine set at 1,000 RPM's, split the difference, and I never hear popping.

I just got them back from recoating a few days ago. I plan to put them on this weekend and we'll see what we can do about a ride by.

Default Got the pipes back, and put on the bike!

Update on the pipes saga!

I got the pipes back from RoadBurner early last week, and just this weekend I've had the time to really inspect them, and finally mount them on the bike.

I can tell you the coating is much sturdier , it is what I was expecting the first time. Originally, any incidental contact with any other metallic surface would leave a clear white scratch, and if you picked at it with your fingernail, the coating would come right off.

This time, that is not the case. I took off the end caps and checked the coating by scratching a small location that was not really visible. The coating did not come off at all.

The coating seems to be much more resilient to chips too. The first time I put the pipes on every single little bump would cause a chip to pop off. This time, no such thing. I even had the misfortune of dropping the front head pipe (yes, I'm a klutz and a moron, I know) and not a single chip popped off the coating. WAY different than the last time. All that happened was some small scratches that did not go through to the metal. I also discovered that some Hi-Temp BBQ grill paint in matte black blends in perfectly and covered the scratches completely!

I put them on the bike and went for a 15 minute ride. No chips or cracks at the end, and the pipes look pristine!

Here are some pics:




I also bought some SmartPartz Quiet Baffles to try and knock the loud down a bit, and here is where I have hit a snag. The end caps on the pipes are not the same size! The baffle fit perfectly into the front pipe, but the rear pipe end cap has a smaller ID that the front cap. The ID on the front cap is 2.13 inches, while the rear cap is 1.92 inches! I thought about grinding down the inner portion of the cap, but I figured that is not going to work since I don't have a conical shaped grinding stone, and I don't have a lathe either. Luckily there is a metal shop close by that has a lathe and will widen the ID for me. Should only cost me about $30 or so.

So far I am extremely pleased with the results. This time around the coating is exactly what I was expecting, and the folks at RoadBurner/DG Performance have been outstanding with their customer service.

Merry Christmas to all, and thank you everyone for your comments and insights! Learned a lot thanks to great comments here!

Merry Christmas!

Doc

Yeah, I've seen this vid, but others have said it did work for them - so it's a toss up. Right now the pipes are just a bit too loud. I'm going to try the SmartPartz first, and if they don't work, then it's on to making my own. I have all the equipment necessary to make a set, it's just very tricky because of the curve and the dual pipe setup.

I'll take a DB measurement before the baffles and after and see if there is a noticeable difference.
