Do funky fil­ters re­quire much fid­dling?

‘You have to prove that the in­creased cost is at­trib­ut­able to the ac­ci­dent’

AI have a 1996 Tri­umph 900 Sprint that I am con­vert­ing to a café racer. If I fit cone air fil­ters, I know I will have to re-jet the carbs, but what else do I have to do? Jim Broad, email An­swered by Clive Wood, Clive Wood Tri­umph You’ll need some dyno time for the carb set-up. Get cone fil­ters with­out a chrome frame as the air needs to flow from the fil­ters’ rear as well as the sides. The orig­i­nal air­box also sup­ports the carbs, so you’ll need to fab­ri­cate a rub­ber-mounted bracket, or the ex­tra weight of the fil­ters will make the carb rub­bers flex and even­tu­ally crack.

The breather pipes from the carbs can con­tinue to vent fresh air be­low the bike, but the breather from the crank­case to the air­box needs to be routed to a vent fil­ter. If you are go­ing to re­ally thrash it, it’ll need a catch tank that vents to air.

When I raced Tri­umphs in the 1990s, we learned how much oil was spat out by the en­gine and had to have a vented catch tank on the rear sub­frame with a foam fil­ter in­side, oth­er­wise fol­low­ing rid­ers would get a face full.

Ever since an ac­ci­dent two years ago I have been un­able to drive a man­ual car due to the in­juries to my lower leg. I have bought an au­to­matic car but my op­po­nent is re­fus­ing to cover the ex­tra cost of run­ning an au­to­matic. Guil­laume Gryon, email


The ba­sis for a claim for fi­nan­cial losses due to an ac­ci­dent is to put you back into the po­si­tion you would have been in, had the ac­ci­dent not hap­pened. This is ob­vi­ously dif­fi­cult in terms of in­juries but eas­ier in terms of mon­e­tary loss.

You say that as a re­sult of the ac­ci­dent you can no longer drive a man­ual car and there­fore need an au­to­matic ve­hi­cle. They are of­ten more ex­pen­sive and over the years there may be a sig­nif­i­cant dif­fer­ence fi­nan­cially. Your solic­i­tor needs to ob­tain sup­port­ive med­i­cal ev­i­dence from a con­sul­tant or­thopaedic sur­geon as to the med­i­cal jus­ti­fi­ca­tion for an au­to­matic gear­box. The sur­geon needs to com­ment not only that it is rea­son­able for you to have an au­to­matic ve­hi­cle as a re­sult of your in­juries, but also that the need for it is di­rectly at­trib­ut­able to the in­juries, rather than a pre­ex­ist­ing con­di­tion. You will also need solid ev­i­dence of the ac­tual cost dif­fer­ence. If your med­i­cal ex­pert sup­ports this claim then hope­fully your op­po­nent’s ex­pert will also sup­port it. If not, then the ex­perts will pre­pare a joint state­ment on ar­eas of agree­ment and dis­agree­ment and the judge will de­cide whose ev­i­dence he prefers and make an or­der ac­cord­ingly.

Re­mov­ing the air­box on a Sprint re­quires more than a re­jet
