Yoshimura Rep Installed (again) with video.
« on: March 29, 2011, 09:17:25 AM »
Got the new exhaust port gaskets and jets from www.z1enterprises.com yesterday.  Installed new airbox rubbers from www.classicmotorcyclesolution.com. Oil/filter was changed, as well as a bench sync. With the 95 main jets it seems happy.  Maybe still a bit lean?  Good acceleration through all RPMs.  Still not as fast as my triumph 900 triple, but I guess that's to be expected.  While testing it out, my tire hit my tail light mock up, and it's now dangling.

My buddy told me that any stainless pipe will change color like that, and it doesn't specifically mean the bike is running lean.

Here's the latest video, please chime in with feedback.  This time the baffle is out.

Sounds great; does it have a baffle in it?
Can you do a "fly-by" sound bite?

This is with the baffle out.

Next time I'm on the bike I will video a drive-by shot.  Sometime later this week.

That's dead sexy.
Baffle is out and it's not too loud.

Where did you buy this beauty?

That looks like a Carpy header.

It was made by Chris at MotoGP. He was the one who origanaly made the pipes for Carpy dont think he does anymore. Thats a 550 not a 750 so Carpy doesnt have these pipes that I know of.

This pipe was made in a small batch by Chris from MotoGPwerks.  The cost was $400+shipping.  He did make the cb750 pipes for carpy, and is a very talented dude.  He worked for yoshi in the R&D department back in the day.

A few forum members got together and asked Chris to make a special set of pipes for 550s like he made for the 750s.  He made them as a favor to the guys here, no profit involved, and it has been a big headache for him for a number of reasons.  I don't expect he is going to make any more, and I don't blame him at all.

Ah, that all makes sense. I can totally understand not wanting to make any more. I have one I got through Carpy and I am very happy with it. One of the easiest headers I have every put on an engine.

Depending on when you bought that pipe from Carpy, there's a good chance that Chris made your pipe too.  He used to produce them for Carpy.

I got mine back in Dec of 2010 or Jan of 2011. Based on the look, I am guessing this is a Chris pipe.

Not a Chris pipe.  I believe he stopped making them for Carpy early last year.



Beastman, your bike sounds great!  Did you have stock pipes on before?

I did have stock 4-4 pipes before.  One had a small rust hole that was getting bigger.

As far as I know, yes.  I have not worked the engine at all.
