ahhhhh, ok. If I'm reading you right, the follow-up answer is that: I could in theory run something different but I would need to know more about exactly how the change in shape would change the compression as well as making sure that it didn't cause any clearance issues. Sounds like I have...

Hey advCo, Good to know, so basically I should get the same exact shape or don't get anything at all, is what I'm taking away from that. If anyone knows of a place to look for pistons I'd greatly appreciate it! Otherwise I'll keep scouring the internet till then.

Hi Experts, I'm rebuilding an engine (74' Honda CL200 bored out .5mm over) and I accidentally damaged the pistons that I had. Unfortunately, the place that I got them from is out of stock and probably won't order more from Japan for a month or more, so I'm exploring my options. I've found 56mm...

Hey All, Thanks for the all the great tips! I was thinking about starting simple and pursuing the laminar flow on my stock carburetors, and found a wide variety of sizes and shapes and prices of velocity stacks available out there. Is there any rhyme or reason to picking one over the other...

Hey All, Thank you for the amazing information! Way more than I would have ever hoped for! The idea about tuning the lengths of the intake and exhaust to maximize the pressure waves is fascinating. If I were to remove the silencer from the end of the stock exhaust to open up the airway, would I...

Hey jpmobius, Thanks for the great insight! I really appreciate the information and the peace of mind that knowing that I probably currently have the right tools to get the most out of my current set up. Just for my own knowledge, can you expand a little on what you meant when you said, "extra...

Hey All, Sorry if this doesn't really belong in the Engines section, but here goes all the same. I'm continuing my rebuild of a 74' CL200. I currently have stock carbs on it (which I believe are 18mm?), but after doing some reading I've seen some people talk about how the stock CL200 carbs are...

Hey Irk, Thanks for the tips! Do you know how much transferablility there is between the tubes used across each year/model? I would assume that the CB200 forks would work for the CL200, but are there any other stock forks that would work too? Maybe a 175 or 250? I'm going to get a caliper to...

Hi All, I'm continuing my rebuild of a 74' Honda CL200 and need to replace the front fork tubes due to the rust and pitting where the seal travels over. I've replaced the seals on the forks before so I'm moderately familiar with working on them, but I have no idea where I should go to get...

Hey All, Long time no talk. I wanted to check back in and let you know that I finally got the new carb slide and definitely had a major improvement in performance. My neighbors are all giving me we weird looks as I ride my bike in 20°F temps, but I'm not going to stop until there's snow on the...

Hey teazer, Here are links to the photos that I took of the carburetors. http://imgur.com/gallery/gYANfk5 Here is the link to the pictures of the slides. http://imgur.com/gallery/Ni1wg0q Let me know if you need any other pics!

Hey Advco, I don't have an actual picture with me now, but this top picture is the arrangement that I currently have 2X of. With the slide cutaway facing the air cleaner and you looking from the rear of the bike, the idle speed adjuster slot is on the left and the alignment channel is on the...

Hey Teazer, That's awesome to hear. I'm really optimistic that this will help to solve my issues. One quick question before I pull the trigger on a new part. The slides that I pulled out of the carbs both say 155 and then 2.5 on them. I think the 2.5 is the cut away size, but what does the 155...

Hey All, The snow started to fly this week which means that the season is officially at it's end. I did however finally manage to get some time in the garage and was trying to sync the carburetors when I noticed that the cut away on the slides wasn't matching the same direction. After taking...

Hey Irk Miller, I can confirm that the cam timing is correct. That was one thing I was very diligent about during reassembly as I was aware how important it is to the overall operation of the engine. As far as air leaks go, her is what I've done: The carb boots looked good, but with the...

Hey All, I got out a few times the past evening and was able to drive the bike around a little bit and while I can get it to start easily every time and idle, it only likes to idle on the left cylinder. The right one will only fire sporadically and that's when I have the idle screwed all the...

Hey advCo, I forgot to mention that, sorry. I did soak the floats submerged in water and did not have any leaks. Also, the gas cap not venting is a definite possibility as the bike was in rough shape when I picked it up. I'll try that when I get a little time this week (hopefully tonight).

Hey All, Checking back in after the weekend of tinkering. I swapped the floats and bowls on the bike and suddenly it started running! I'm convinced that nothing gives your brain endorphins like a motorcycle kicking to life. There are still some issues that I have to work out though, as the...

Hey All, So after reading the post by AdvCo about how 115psi should be enough to get it running, I decided to look elsewhere for issues that might be causing my problems. I eventually found that the right side carb (although properly set to the spec. float height) was not letting gas into the...

Hey advCo, This was a new OEM advance mechanism that appeared to have never been installed before. As far as the cam lobe being 180° out of sync, I'm fairly confident that I installed the cam shaft correctly according to the manual. Placing the "spark advancer knock pin facing upward" and...
