CL175 - Runabout

CL175 - Hell on Wheels

Thanks! This is just my little runabout so there shouldn't be too much to be impressed with :

I did get the leak figured out - it was the clutch pushrod oil seal and the shift shaft oil seal as I thought. I replaced them and the major leak definitely stopped. I found another small leak though from behind the tach drive housing on the right side of the head, so I have to tear that off this winter and replace it as well. Not a big job but when you have to use PB blaster and an impact driver on every screw it's all a headache.

I got the baffle idea from the forum here. They seemed like a good idea but even with them the straight pipes were still quite loud. I eventually caved and went back to generic shorties to cut the tone down a bit. Its still loud but at least I don't get as many evil stares from my little old lady neighbors.

As for intake, I am running stock airboxes. I've read quite a bit about how these motors are finnicky about total intake tract length. I think something like 9-10" from the intake valve is ideal but don't quote me on that. The bike came from the PO with generic pods and ran a little rough but really perked up when I put back on the stock airboxes. The airboxes have a great little rubber manifold tube that adds a couple inches. I think combining those tubes with pods or using long velocity stacks may work as well.

I've been playing around with jetting. I had a large 105 main/38 slow in (per a recommendation from Teazer) but was running rich so I scaled it back to a 98 main/38 slow (which is stock for CBs). I believe stock for CL carbs is 90/38 so I may have to go back down even more. I picked up a bunch of main and slow jets from JetsRUs (good buy BTW) so I've got plenty to play with.

I was actually inspired by your thread to get do some work on this. I actually just came from the garage where I've been tearing apart the front end to clean up the fork tubes, polish the lowers, replace the fork seals, and paint the triples and bar mounts. Should make it a bit less ratty, but not too much. I actually want a little bit of the rat to stay with this one...

It's interesting, I actually had the tach drive leak before I tore mine down. I'm hoping that the new gaskets help solve that problem.

I have also heard that intake length helps. That's why I'm shooting for long velocity stacks as you mentioned. If that's a true statement, it's a win win as it will help performance and look baller!

It's good to know that you were close with stock jetting, even with nearly open pipes. That gives me optimism that I won't be far off with long velocity stacks and stock CL exhaust including the muffler. I'm terrified of jetting and hate taking carbs on and off so I may leave this portion to a professional nearby. We will see!

awesome bike man, your write ups were very helpful in decision making. I stole a lot of your ideas! Namely the baffles. Works great and sounds pretty cool IMHO. Check out my build:

Sweet bike! I would stare at it for hours on end...looks like it will take a beating.... I love stout

Thanks Mike! It is definitely a tank with the bored out motor and knobbies. When I get a chance I'll post some updated pics. It's been on my table all winter so I could go through everything front to back.
