    Ninja EX500 carbs on an XS650?

    Those look a little lean but is that from a WOT plug chop run? I have 138 mains, straight through shorty mufflers and foam filters and she runs great at WOT. If your running steady 80/90 mph, are you at WOT? If you're at 1/2 or 3/4 steady throttle, the needle is doing the metering. I also run...

    Slide and Diaphragm Shaking?

    They are a direct swap. You do have to modify the throttle cable holder. There are many ways to do this. There's a huge write up on this swap that covers every question that has ever come up. First step is to read the forum so you know the proper jets and needles to get. This is critical to a...

    Slide and Diaphragm Shaking?

    Not to get into a PODs vs stock airbox rehash, but I've done PODs many times as well as friends and from what I have experienced, most issue are due to jetting more than anything. De-restricting the airflow into the carbs will change the A/F ratio and will require jetting changes. In your case...

    Help with strange triple trees issue

    Sweet. Thanks gggGary! I measure, not super precise, the billet clamp at 50mm offset so as surmised, they are off 3mm. Should be a simple fix. I'll pass along your measurements to them.

    Leak advice

    That pushrod seal leaks from the inner hole that seals against the pushrod itself. I too had a leak that at first I couldn't figure out since I had replaced all the gaskets and the pushrod seal when I had the engine apart. It turned out it was the pushrod bushing was worn which allowed the...

    Help with strange triple trees issue

    No lowering the bike. I've fitted and refitted many times and different ways thinking I had something jacked up. My stock triples fit just fine. I've also measured as have others and the measurements do not line up. The Cognito stem offset is around 50mm. Stock is closer to 47mm. They are not...

    Help with strange triple trees issue

    All this is awesome! So, if I read the measurements correctly, so far we have the following approx measurments: 70-72, 34mm forks, uses a 174mm fork to fork on center measurement, offset is 60mm 73 - 34mm forks, 184mm fork to fork on center measurement, offset TBD 74 - 76 34mm forks, and 77+...

    Help with strange triple trees issue

    gggGary is spot on. I will say the folks over at CM have been very helpful. I love the look of the clamp they designed, the clean look with the hidden hardware, and it fits in with my project perfectly. It really is a beautiful piece. I'm just trying to determine if it was something simple like...

    Help with strange triple trees issue

    I spoke with Cognito folks. I'm sending the clamp back for them to check into what's going on. But, before I do, I want to make certain it's the clamp and not the bike. Anyway, I'm curious what the measurments are from an earlier model bike. Maybe they used the 34mm dimensions and just cut the...

    Help with strange triple trees issue

    Ok I measured the same 184mm fork to fork but I'm measuring 104mm from fork tube to stem (center to center). 47mm seems way off. Are we measuring the same thing? I'm gonna call Cognito this week and see what's up.

    Help with strange triple trees issue

    Thanks guys. I liked the design and cleaned up my dash area since I wasn't going to run the original speedo setup. There's no slit in the fork clamp but instead uses a pretty clever part that squeezes the fork via a piece that is cut to match the inside of the clamp curve and is tightened via...

    Help with strange triple trees issue

    Gents, I've run into an odd issue with my triple clamps. I have a cognito moto billet top triple clamp for the 35mm forks (mine's a 1980 XS). When I went to install it, the forks would not line up into the holes. After looking at it a bit, it appears that the steering stem hole does not line...

    Front MC Guidelines

    This is on an '80 which is in my sig. Hmm, thanks 5twins. Mine is exactly like you described. I think I'll go back to stock 14mm and try that.

    Front MC Guidelines

    Ok my goals for the Front brake are to have a modern, light pressure but progressive feel to the front brake. I'm not made of money so I rebuilt the stock caliper, fitted a drilled rotor from a newer Yamaha, got an 11mm bore MC (cheap evilbay variety), Mike's Kevlar brake pads (#29-3522) and a...

    Chaising the infamous hanging idle - Carb tops possibly?

    Well after 3 trys I've finally gotten her to a ridable point. I ended up replacing one of the slide diaphragms and went to a larger pilot (47.5's) and that seemed to help a lot. I might swap both diaphragms for brand new ones. She still has a very slight tendency to idle hang just a bit but not...
