    Both of these are for Maxims, but your forks are similar.

    I found some at a motorcycle yard from another old Yamaha but not sure what kind of bike. I notice they had rubber around the edge of the mirrors.

    Thanks! Couple of questions. I came across this video where the gentleman does the procedure without ever taking the forks off the bike. Is it possible to do the same procedure on my bike?


    Secondly, I'm considering putting on a fork brace that goes right above the fender. I know it can't hurt but is this a waste of time or worth putting on? If it's worth putting on could someone direct me to a brand that fits the Seca 650? thanks again.

    I would not reccomend changing fork seals with the forks on the bike. You can use the lower triple clamps as a vice to aid in some parts of the work, but I find that most of the job is easier with the forks removed.

    The front fender has a built-in fork brace.

    I'm getting the Mexican jumpin bean effect on my speedo. I replaced and lubed the speedo cable and it still happens. Any simple fixes before I feel I have to take apart the cluster?

    Not too sure how far you can brake down a cluster? Looking forward to answers...

    With that cluster you should be able to carefully dismantle it and lube the internals of the speedometer itself. Be very careful with the delicate parts inside there and use something to direct the lube to the exact spot you need it and not have it get all over other parts that it may discolor or otherwise degrade such as the gauge face, etc

    Turns out all I had to do was put some chain lube right where the cable goes in. I actually sprayed a little carb cleaner, waited a few minutes, then put chain lube in there and it works like a charm now.

    Would anybody have the torque specs for a couple things: fork clamp bolts both upper and lower, bolts holding the brake rotor, pinch bolt, damper bolt at bottom of the fork. Thanks

    What would you recommend if you have a flat tire but can't find the hole. I've tried to locate it on the sides and all around but there's no obvious hole that I can find. Should I start with a sealant or should I immediately take it to a pro and get it patched? I'm trying to avoid a new tire but if I have to, I have to.

    So, I filled up the tire to the required 42psi so that there is pressure in there for bubbles to form. I sprayed Windex all over the tire and I couldn't find a single bubble. I then went for a ride of about 25 miles. I came back and checked the pressure: still at 42psi. Hmmmmmmmm.

    On a different note does anybody have a way of adjusting the rear shocks without using the special tool. I'm a lighter guy, 160lbs, and right now it's on the middle setting or "C" setting and I want to experiment a little bit.

    Might just be a sticky schrader valve. Keep an eye on it. As XJ550H said, cold and hot will be different.

    Adjusting the preload collar? A hardened steel rod of the correct diameter (you might find a phillips screwdriver that fits, just grind the tip off so it's square, and chamfer the cut end with a file). Stick it in the hole and turn.
    OEM toolkits are usually all over Ebay for cheap.

    I ended up using a vice grip on the rear shocks and it worked brilliantly. Onward.

    Next major job is replacing the swing arm pivot bearings. I can't seem to find many tutorials or pics of the bearings, collars, seals, ect. Can anyone direct me to a starting point on how to do this job? Thanks.
