If we don’t know the answer, we’ll find the person who does
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.
