280mm EBC front rotor, came with bracket for the caliper.
Good feel & lots of power (for off road)
The original worked OK but I was experiencing forearm pump on long down hill runs in very steep terrain.
Very happy with the results.

Anybody seen this exhaust? It's the honda works bike pipe. Must be loud as all hell.

There's one on e-b-a-y right now.

I have the same pipe and it's not to bad if you run the sparky srceen in it.
But yes it's loud but not as bad as a Harley.

You could put a smaller end cap on it to reduce the dec.

Preventative maintenance completed yesterday.........top end rebuild with new rings/gaskets........got an extra base gasket if anybody needs one....

No real issues discovered during the rebuild although it's very nice to know that I've resolved my confidence issues. I had taken the piggy for a swim in a creek which put water into the top end. The rebuild demonstrated that the cylinder, piston and rings were well within spec.........but now I know the bike is even a bit better.

It was in the upper 30's here today and I ran the bike for a 30 minute ride to begin the break-in process....

And just to throw some iron in the fire.......

........how do you break in your piggy?

RE: water in the cylinder...

Thursday night my bike was in the back of my truck overnight, and it rained. A lot of rain! Apparently, the exhaust and cylinder filled with water. I would imagine about 2-3 quarts of water were drained from the exhaust.

To remove the water from the exhaust, I laid the piggy on the right side and picked up the front end. Then, I removed the spark plug and kicked it over quite a few times to remove more water from the cylinder. After some persuasion (carb cleaner, kicking, and a little fire in the airbox

) she started up. I let it warm up some, changed the oil. Then rode it and let it get hot, and changed the oil and filter. Today, I rode about 200 miles, and will change the oil again tomorrow.

So, moral of the story is: My pig needs a butt plug, or being more practical, needs a turn down exhaust tip. I like this option more due to the possibility of reduced noise. Anyone know of a turn down tip for a stock exhaust?

A little late since you rode it for 30 minutes...I flog the hell out of a new engine, hard up thru the gears, drag the rear when slowing down..just like normal riding.

Vary the revs and don't baby it.

$50, probably any custom muffler shop could do it. Just take them your end cap and tell 'em what you need.

FWIW, it blows below 99dB still (I think 96 at last check, 90 another time) and is only slightly louder than stock with the cork + s/a in it.

An oh yeah, I painted it dog dick red... kinda faded now!

I like it!

I'll see if I can find someone in town to do this for me.

Thanks, that sounds like something I want.

Sorry to answer an answer with a question but what is "arm pump"? I've seen the expression a few times. Tired clutching/braking muscles?

Any muscle can get a pump, it occurs when you are using a muscle extensivly. The incoming blood cant be expelled as fast as its comming in and your muscles swell up. It reduces your ability to flex the muscle and movement is also decreased.

Cool looking pipe yes but for $550.00 you will not get a major hp increase, a small amount on the top at most. It's a pipe tuned for holding wot for a very long time. it's not a power maker, in comparison to any other full pipe. It is a beauty though.

That is a nice pipe hulk, saw it on e-bay and though about it for 1/2 a second. just looking at it I'll bet it's probably pretty loud. In my expierence most aftermarket pipes improve mid-to high RPM with a low RPM sacrifice The stock pipe doesn't flow very well at high RPMs but works as well or better than most in the lower 1/3 RPM. That's one of the reasons I've held off on a pipe, if I have to take a low RPM hit and put up with something thats real loud I'm ok with just the HRC tip. I'll probably end up with a slip on but I've been considering building a slipon copied after the KTM hockey stick style silencers.

I admit to chumming for some controversy......I followed the procedure here: http://www.mototuneusa.com/break_in_secrets.htm

Even after the first ride, the beast was beastlier than I remember........

pwrtrippin · 12-20-2009, 09:22 PM

Ridefreak, I run a Leo Vince slip on on my bike, its got a nice tone to it and with the quiet tip in it, I still have the low end grunt with a good bit of power on the top. Now I just wonder how much powershift would be had with the head pipe replaced too.
