    Hi All,

    I am new here and I've just bought a Suzuki GT250 X7 with wire wheels, which are not very common in the UK.

    The speedo drive does not seem to have a locating pin/groove in the left hand fork leg and seems to be relying on the cable to stop it rotating. Is this how it should be?

    Thanks,
    Dean

    Welcome.
    Does it just need the axel tightened to hold the speedo drive in place?

    Welcome. No, doesn't sound right. What did the previous owner say about the wire wheels/ speedo issue?

    I don't think there is any point in asking the previous owner. He obviously has no idea, judging from the state of the rest of the bike.

    I'd really like to hear from someone who has one that is working correctly!

    I don't own a X7 but the parts diagram sugests that you install it with the "up arrow" up and torque the axle, hope this helps

    Thanks for that. Looking at the speedo drive, there doesn't seem to be any notch or peg to locate in the fork leg anyway. I don't think tightening the axle is a good engineering solution, but if that's what Suzuki intended, I'll have to go with it!

    I think you are pointing to the drive notches in the hub. These turn the two prongs in the speedo drive. This makes the drive unit want to rotate in the direction of travel. On most other bikes I have seen, the speedo drive is located with a peg on the fork leg.

    There must be an X7 owner out there who can confirm the correct arrangement.

    Yea then the nut #6 holds everything (axle, bearings) in place in the hub and the outside lug #5 tightens the fork leg and the speedo housing onto the hub ... ?

    Theres not alot of X7 owners about

    That will work, just in my mind, it's not very safe. I guess the split pin would have to fail and the spindle nut loosen for anything bad to happen, which is pretty unlikely.

    Thanks for your help though, maybe I just needed someone to say it's okay! Two (or more) heads are always better than one.

    #5 doesn't exist in the UK market bike. I think the parts diagram is actually for the older GT250, not the X7, but the principle is the same.

    i took a look on cmsnl.com, they have the parts displayed. They're not cheap but have a lot of stuff.

    I have the parts microfiche. It doesn't show the inside of the left leg though.

    I'm on holiday now, until the 6th June, so I'll catch up when I get back!
