Q How can I stop my jud­der trou­ble?

Motorcycle News (UK) - - Garage -

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.
