I had a few spare moments Saturday so I put on my new set of Preds that I got from Sam. I pulled off the Jardines rather quickly. It took two days to put those suckers on (seriously) and all I had to do to get them off of the bike was to take off the 6 manifold bolts, the two rear foot peg bolts and the little chrome cover over the rear brake master cylinder and the whole set of Jardines came off as a complete unit and is now sitting in my basement. I think the Preds weigh half of what the Jardines did, and we won't talk about the stock system....
The Preds went on just as quickly, it probably didn't take me a half an hour to mount them up. That would include putting on the heat shields (I put some high temp anti sieze on the bolts) and the spiffy chrome endcap that I got from Summit racing. Supertrapp wanted something like $115 for that and Summit had it for $85. I already had new exhaust gaskets.
At first I just used the baffle supplied by Supertrapp and the chrome endcap and went out for a short ride. It was loud. It was soooo loud that after a short 3 mile jaunt I had a headache, my ears were ringing, my ears actually hurt and I set off two car alarms. I did totally out noise a Harley so that was fun. It was just too loud to be enjoyable. So as you can see in the pics I put in the supplied tuning disks to quiet it down a tad and they did their job. It is still loud but really, not bad at all.
So I went back out for another short ride and it ran better with the disks. Actually, quite a bit better. I have all twelve disks in there and it didn't seem to affect the top end (using the highly accurate seat of the pants dyno) but I have more punch down low. So much so I can make the front very light just by cracking the throttle, and I actually was able to get the front wheel up a couple of times just messing around. Keep in mind I have Nev's mild cams, the comical K&N RU-1770's and some other mods that I don't want to bore you with.
These pipes are a step up from the Jars. The Jars ain't bad though. I haven't done anything to tune the bike yet, I just haven't had time. I want to get over and have it dyno'd. I did get out for about a half hour ride today and it seems like I may be lean as the bike was running hot, and I'm not talking about heat from the pipes.
Is anyone else running the disks? If so, how many are you using? I may take 4 out and try 8 just to see how it does. And how did you dyno it? I may need another of the cheapo thin endcap and drill a hole in it for the exhaust gas probe to go in, these pipes have no bung for an O2 sensor so I can't go in there.
In fact, if anyone has the set of disks and the thin cheapo end cap that they are not using (4", 6 hole) I would probably take them off of your hands....
