Sporty muff with no jetting
05/18/06 at 14:17:53

I've read a bunch of threads and it seems like installing a sportster muffler without any other mods will make the engine run even more lean than it does now (I live in CA). The problem is I am going to install the muff myself (thanks mike Bobo), but I am going to have a shop do all the jetting and carb mods. So, I need to ride it on the interstate 5 or 6 miles to the shop with the new muffler, but no carb mods. Will this hurt my bike? (it's an '06 S40) Will my bike perform at interstate speeds like this? I really appreciate any advice.

It's more of long term engine health thing. So far as interstate speeds - sure it will run that fast - have you had the stock bike out there before?

yeah, I have about 600 miles on it, and have taken on the interstate 6 or 7 times. So you think it shouldn't be a problem to ride it around like this for a short while?

I love the bike, it's black and now that I took all the decals off it looks really clean and classy. I just can't wait to get a better sound and performance out of it. Wink

hah, right on. I ride to school everyday and then to where ever I need to go. So I guess it's a commuter, but it's a pleasure everytime I ride it so.... I usually stay in the surface streets since I live in downtown San Diego, but I also take it on the freeway when I need to. I want to get the mods on it before I ride it on the interstate a lot.

You'll be fine riding without a rejet for a bit. I wouldn't beat on it until it's rejetted though If it were me, I'd ride easy until the rejet.

If not, I would not do anything to it until then you will void your warranty ???

Paint isn't covered. I tried. Nor are fork seals, brake consumables (including the caliper), shift linkage, tires, bulbs, inner tubes, rim liners (big rubber bands), cables, wiring, fuses, grips, mirrors, chrome.

I did get my muffler replaced under warranty, it rotted out a couple months post-new bike purchase.

My bike has been running a near open pipe, on stock jetting, for 7 years. The headpipe and muffler are a funny shade of purple now, but it runs fine. And gets stellar mileage (has gotten a high of 85 mpg on the freeway). Mine seems to be an exception though, most of the other bikes need jetted when the pipe is modified.
