Q Can I sort my bike’s poor fuelling with a bolt-on gadget?
I know it’s a fairly common problem on many modern fuel-injected bikes, but my Triumph Speed Triple 1050 suffers from mad snatchiness on the throttle, especially at low revs. I found this website for something called a Booster Plug, which is supposed to be a plug-and-play device which sorts it all out. At almost £125 it’s not cheap, but if it worked it’d be worth it. Barney, MCN forums
A Answered by Clive Wood, Clive Wood Triumph I have never fitted one, but I have removed plenty of similar systems! They fool the engine electronically into running rich for a while, but after a period of time the bike’s adaption system will correct the mixture to protect the catalytic convertor from damage by excess fuel.
Once armed with the correct computer software and plugging in your PC, you need to make sure the bike goes into closed loop mode and is set-up for ‘closed throttle adapted’, which means the throttle always returns to same spot so the ECU can learn a reference point. That won’t work unless you set the throttle freeplay so it stays fully closed on full-lock.
Next, balance the throttle bodies. This has the biggest effect but rarely gets done as you need to remove the tank and airbox, then reassemble it all without the airbox to give you access. Doing all that probably takes an extra 1–2 hours.
I have a question about the helmet I was wearing when I had an accident in April. The helmet was a gift which a friend bought in Spain. I had no idea it was not road-legal – the police say it had no BSI Kitemark. When I came off I knocked my head and have since had migraines, dizzy spells and a slight twitch. A neurologist has linked these symptoms to my accident but the solicitors for the driver who hit me say I can’t claim compensation due to my illegal helmet. Is this correct? Justin, Cardiff A All helmets worn on UK roads must either: O Meet British Standard BS 6658: 1985 and carry the BSI Kitemark O Meet UNECE Regulation 22.05 O Meet a European Economic Area member standard offering the same safety and protection as BS 6658:1985, and carry a mark equivalent to the BSI Kitemark.
So, the issue you need to obtain evidence on is whether or not your helmet satisfied the Spanish rules, carried their equivalent of a Kitemark and prove that the level of protection afforded matched or exceeded the British standard. If you can do so there will be no contributory negligence or reduction to the compensation you can receive.
If the helmet is deemed not to have satisfied the British standard then the court can reduce the compensation if it is accepted by the judge that had you been wearing a legal helmet you would not have sustained a head injury or that its effect would have been lessened. If this is likely to be an issue your neurologist expert will need to deal with this in his/her evidence.
