Q How can I stop my judder trouble?
I have a lovely 1998 Yamaha R1 that sometimes suffers from a nasty case of juddering when pulling away or pulling up at a walking pace. This tends to occur when the bike has been running for a while. If I pull in the clutch and then release it again when the juddering has started it seems to solve the problem. I have adjusted the clutch bite point and replaced the clutch plates, but the problem persists – and this is the second R1 I have owned that suffered from this issue. What could it be?

A Answered by Charles Marvell, Flitwick Motorcycles The juddering sounds like a worn clutch basket. Early R1s had a recall on the clutch basket and you need to check through a Yamaha dealer whether this has been done. Even if it has, the entire clutch assembly, basket and all, needs to come out for a closer look as they do take quite a beating.
Check the overall condition of the basket, looking for notches in the sides or tags missing. Check the condition of the springs on the back of the basket, there are six of them, three ‘tight’ and three ‘loose’ and they operate like two-stage damping. When you replace the friction plates, replacing the steel plates at the same time is good practice as they can buckle which will cause drag. A new clutch cable might not go amiss either.
‘Your son needs to prove the defect was there from the start’
Can my son Q reject his bike after 18 months?
My son has been riding his KTM Duke 125 for 18 months from new. It first broke down after three months with a fouled plug. It has since broken down a further five times, which up until the latest failure all seemed to be fuelling-related: two instances of fouled plugs, new throttle body and a new intake system. The latest has been put down to a wiring loom failure.
All have been repaired under warranty, but sadly we have lost all confidence in the bike and the dealer’s ability to fix it.
I would like to reject the bike on the grounds that it is ‘not fit for purpose’ under the Consumer Rights Act. Is this a possibility after 18 months? Mick, email A The first thing to identify is precisely when your son bought his bike, because if he bought it 19 and a half months ago it would fall under the Sale of Goods Act 1979 not the Consumer Rights Act 2015 (CRA). Assuming the 18 months is accurate and the CRA applies, he has to (i) prove the defect was there at the point of sale and (ii) give the dealer an opportunity to fix the defect as it’s over 30 days from point of sale.
If the fix is unsuccessful he can request a refund, negotiate a price reduction or require the trader to attempt a further repair or replacement.
As the defect was discovered after six months your son must prove the defect was present on receipt. If this is proven and the repair or replacement fails, then he is entitled to a partial refund to take into account the use of the product.
