Q My fan stay­ing on is not cool

The fan on my 2012 Yamaha FZ6 is run­ning all the time, even be­fore it’s got up to tem­per­a­ture. I’m guess­ing the fault lies in ei­ther the ther­mo­stat, tem­per­a­ture sen­sor or fan mo­tor re­lay area. I’ve tested the re­lay with no luck. James Ark­less, New­cas­tle-upon-tyne

AAn­swered by Charles Marvell, Fl­itwick Mo­tor­cy­cles That will be the tem­per­a­ture sen­sor. Ei­ther the sen­sor it­self has a short in it, or there’s a short where it plugs into the loom. I’d lean to­wards a wiring short, and fully in­ves­ti­gate that be­fore get­ting a re­place­ment sen­sor as they aren’t the cheap­est item on the shelf.

Q How can I stop bad vi­bra­tions?

I’ve got a Tri­umph Ad­ven­turer with 16,000 miles on the clock that’s de­vel­oped an an­noy­ing vi­bra­tion through the bars. It used to be at 8000rpm and I could tol­er­ate it, but it’s shifted down to my ‘cruis­ing range’ be­tween 6000-7000rpm. Ge­orge Jenk­ins, Snet­tisham

AAn­swered by Chris Dabbs, MCN You can ‘tune’ it out to a cer­tain ex­tent. After­mar­ket bar-end weights from the likes of R&G should help, as will pack­ing the clip-ons them­selves with lead flash­ing, or even those poly­styrene ‘cater­pil­lar’ pack­ing pieces. You could also con­sider jack­ing the en­gine up in the frame frac­tion­ally, then loos­en­ing and re­torquing the en­gine mount­ings, and make sure the throt­tle bod­ies are bal­anced.

Q My Blue­tooth bar­gain hunt

We have re­cently pur­chased two Shoei Qwest hel­mets. We used to use a hard-wired in­ter­com sys­tem but it’s a bit cum­ber­some so we fancy a rea­son­ably priced Blue­tooth sys­tem for chat­ting, us­ing the phone and lis­ten­ing to mu­sic. John Or­mond, email

AAn­swered by Keith Rois­set­ter, In­fin­ity Mo­tor­cy­cles Th­ese days ev­ery Blue­tooth kit lets you take calls, lis­ten to mu­sic via your phone, and hook up to a GPS, but if you go bud­get you lose speaker qual­ity. The most dis­crete sys­tem is the Au­to­com Air-2 at £349 which slides into hel­met liner at the rear, but other units like the Sena SMH5 Dual for £179 and Cardo Scala rider aren’t that bulky, and the Cardo is rec­om­mended by Shoei too.
