Hello everyone. I'm working on a CL175 to run in a one day endurance race called http://www.lakeerieloop.com it is a 660 miles small displacement 200cc or less] race starting in Ohio and going up through Detroit, into Canada, exiting Canada by Niagara Falls and traveling through NY and PA to return to Ohio.... - Just a little background for you.

So I'm having a hard time getting out of the starting gate here. I've fabbed up a tail and moved the footpegs back - no prblem there. I am looking for a cheap over sized tank solution if you have any suggestions please let me know. I also have a CB200 and they appear to have the same "backbone".

The real problem is though I cannot get the carbs running properly. When I start the bike it races like a son of a gun. In the neighborhood of 4000 rpms. I've adjusted the 2 idle screws every way from tuesday but believe the issue is with the throttle cables being threaded incorrectly. I'm embarrassed to say when I did the teardown I paid little attention to the way it was threaded. If everything goes as planned I am going to replace the tank but I have to go on the assumption that as of right now this is the way I am going to run it. Have any of you guys run into this issue?

Do the throttle cables go over or under the saddle hose from the left to the right side of the tank?

Do you know of an affordable solution to a large tank to fit this small Honda twin frame? My target is about 4 gallons if possible.

Any long distance setup suggestions?

31mm clipons - is this correct?

This is a charity ride and there is a certain amount of bragging rights for the cheapest setup... oh, I'm a cheap poor bastid anyways.

Thanks for any help, suggestions or reality check and, for reading this far.

Kev - aka nixoid

Sounds to me like you've got the left slide in the right carb and vice versa. The cutout on the bottom of the slide should face the air filter. I'd check that first.

If its a one-to-two split throttle cable, make sure the cables are seated properly in the "splitter" and seated properly in the top of the carbs. Common malfunction (and easy fix) with these cables.

Routing should employ the smoothest curves possible, you know, path of least resistance and all that shit. By the way, if you can hear and feel the slides "snap" shut when you release the cable, your engine racing problem is probably not routing.

My guess is air leak at the manifolds or cable hanging up.

I've read about that rally and want to do it one of these years.

Might wanna look into a cheap aftermarket throttle lock (a.k.a. "cruise control") and a wool seat pad.

The cable does snap back smartly. I lubed it as soon as I got it. I'll check the slides but they only go in one way... I've pulled the darn tings out a bunch of times but I'll try again.

You should come do the race. We had a guy from Motorcyclist magazine come out to do a story and he emailed me recently to tell me it would be in "this Spring" If you are interested join the Yahoo grouphttp://autos.groups.yahoo.com/group/lakeerieloop/

So what is the easiest way to determine an air leak? soapy water?

Kevin,
The guide pins for the slides in each carb. are one the inboard sides of the bores. In the photo below you can see the slides are mirror images of eachother. If the carb slides are switched, left slide in right carb. and visa versa, the cutaway will be pointed the wrong way around.

The CX500 tank on my CL175. It was cheap, and was pretty easy to fit.

Thanks Burt...

I'm a little thick here. I need to spit this back at you so I understan it properly. The guidpins should be in the center of the bike and the the cutaway is the shorter of the two slots in the slide<img src=icon_smile_question.gif border=0 align=middle> I have to go look but I believe that I have the longer slot that a use to insert the throttle cable lined up with the guidepins. I confuse easily - 'preciate the help and especially the time you took to snap and post the photo.

Thanks Chip.

That is exactally the type of fix I'm looking for! There is a certain amount of pride in having the most jerryrigged short pocket racer for this event that this will definately satify. By chance do you know what year this came off of? Any special mods you had to do?

Kev,
The beveled area at the bottom of a carb. slide is the cutaway. I edited the photo above to better show the correct orientation of the slides. Make sure this cutaway (red arrow) is facing towards the air filter. If when installed the cutaway is facing the motor, the slides are in the wrong carbs.

It's off an '81 or '82. There are two different CX500 tanks, so make sure you see a pic before you buy. The tank is too wide to use the factory mounting bungs(or whatever they're called)in the front, so I welded longer ones a little higher to get the position I wanted. If the tank you buy doesn't have the pad you'll probably be ok because on my bike it's not sittng right on the frame.

Cool Chip.

I just picked up a welder and have been trying to figure out where to use it. If the tank isn't on the frame does that mean its sitting on top of your seat? How are you supporting and securing it in the back?

The back of the tank sits on some rubber pads I made, and is held down by the seat

Cosmoploitan motors sells them from time to time on ebay. Haven't seen any in a while though.

UPDATE:

I finaly got around to checking out the float slides and yes, they had been swapped to the wrong sides. I swapped them into the proper carbs and with the wee bit of gas that is a bit funky I started it up and it was racing a bit maround 3k but I have to adjust the carbs and I am confident that this willl smooth it out. Just need gas and I rode to work today so I didn't have a gas can with me. Thanks Bret!

Bought a cx500 tank on eBay. The sloth waited 10 days to ship it AND sent it Parcel Post which is about the slowest type of shipping available AND he charged me $26. He'll be getting [and Chip!

Brent of http://www.motobits.com/ set me up with a pre-release pair of rearsets for the CL. These things are absolutely beautiful. The highest quality rearsets I've seen out there. Buy stuff from him.

I need to sit and figure out how to add images. She is still in the earl stages of development though. not much of a looker. Frankly, it may never be considered a pretty bike. I'm going for pure utility. If I get it done in time to spruce her up then I will think about the aestetics.

So I have a petcock for this tank and it kind of confuses me a bit Chip.... There are three outlets. 2 smaller and one larger. Is the larger one and overflow and the two smaller ones are for fuel? Also, I haven't looked yet, are there petcock rebuild kits available for this sucker?

Hmm, the one that came on my tank only had one outlet, but I used a dual outlet petcock because it's the only way I could manage to keep the bowls from running dry at high speed

Well thanks to the help of you guys the bike is up and running beautifully. I finally have the slides where they belon and she purrs like a kitten. Starts on the first revolution of the starter every time. I also took Chips advice and mounted a CX500 tank. Talk about changing the lines. My sister was visiting and barely recognizes changes in my bikes but this one really stuck out to her. I am still fabbing out at seat for the beast and this is the reason for this post.

As I stated earlier I am going to spend around 11 - 12 hours on this bike in one day in an endurance race and need some foam suggestions. I've been told that gel is great and believe this to be true but I am hesitant to purchase anyting without first knowing if a particular brand/formulation is actually a liquid which will run if I cut it down. Also since I am fabbing up the complete seat are there any combinations of gel to a aprticular style of foam that anyone has used succesfully? Leather I have in abundance so that will be my cover and I have snaps but as far as securing them to the fiberglass I am at a loss. can anyone suggest a raticular type of hardware or even a snap that comes complete for this type of application.

So here is my current shopping list:

1 - gel material
2 - foam
3 - snap hardware

Any and all help will be appreciated.
