    Hi guys and girls

    I currently have a Lintex HT125T-15 and I'm having a slight problem. When riding it and I go over the slightest dip in the road or small pot hole my scooter centre stand catches the road. I also end up bouncing around 2-3 times. It has a single shock absorber on the left.

    Also when turning round tight corners the centre stand catches the road.

    I have checked the stand and it's all positioned fine. When held upright there is plenty of clearance from the ground. The previous owner was a larger frame.

    For your advice please.

    Lubricate your pivot points,
    Replace return spring,
    Check thickness of isolation rubber between stand
    and frame.mk.

    Pivot points?will give this ago. Will it be ok using the bicycle GT Spray?. But as far as I could see it appeared to be going up. Could it be the shock?

    Would use a more suitable grease myself as you'll want something that lasts/not just short term lubing,
    May seem to operate fine,but previous owner being of larger frame? -
    as you do sometimes/just hop on an push off stand could weaken return spring.may
    seem to be working but not as effectively,
    Sidestand would sort grounding probs.out no worries if interested and fittable as there
    are no doubt a few universals about.mk. :) .

    Very decent of you to refer to the previous owner as "of larger frame".
    Everybody else would have called 'em a fat B*^&%&$£D:p
    Is the rear shock adjustable at all? Might be able to stiffen the ride a bit to stop the excessive bouncing.

    Steve I have had a look and at the manual and it doesn't appear to be adjustable. I have greased the stand but still does it. I have got another person to sit on it and you can see the centre drops considerably. Do you think it's worth changing the shock at the rear.

    If the shock absorber is badly worn or has leaked damper fluid out, you'll be driving a bouncy castle - does this sound about right?

    Merlin not sure about the leaking fluid as it was like it when I bought it. However a bouncy castle is a good way of describing it :) you think it's the back one or the front forks.

    itll be the rear fella, bring it over my way and ill tell ya what it is, but a rear shock sounds like a good idea if the previous owner was as big as you said they was the other day

    I concur - the rear shocker is bolloxed.

    And put a new spring on the centre stand, that'll sort that out too.

    Will give it a go. Is it pretty straight forward to get the shock off? It only has one!!

    Top and bottom bolts out and that should be it. You might want to tip the bike back on the stand, to let the ground take the weight of the engine as you remove the mounting bolts. Same thing in reverse to fit the new one.

    I've today taken the rear shock off. When doing so the scooter frame lifted. It didn't drop. Went to the shop And they didn't have one so when putting this one back on I've had to push the frame down to get the bolt back in. Maybe this is why it's so low????

    No, it's because the front is heavier than the back, nothing unusual. Why didn't you order the shock first and then change it? You doing the job twice now. Good practice for you and a confidence builder but........

    When I phoned the store they said because it was Chinese they would need to compare it against others they have in stock. I did this and they didn't have one. But now I know how to do it so.....
