Some time ago I purchased a speedo head on e-bay from India . Cost the ridiculous amount of £22.00 plus postage and once received had to be sent back has they'd supplied KM instead of MPH. Much to my surprise the correct head was returned along with a note apologising . Well I had an initial spurt to try to use it but being as duly reported by me here before I have the attention span of a demented goldfish the speedo lay neglected in a box .Until about a month ago where griped by the prospect of the permafrost finally receding this year ( ok bit of an exaggeration but it as been cold here on merseyside even our squirrels are still hiding there nuts if you follow my drift
) Anyway a quick check spinning it and working out rotation of our g/box drive seemed to confirm what Musky had said some time ago ie that it would work. I set about sourcing a new cable. contacted Venhill engineering who confirmed that they could supply a cable with BSA at the g/box end and royal enfield at the other, just gave em a length and a week later I had a nice new cable which fitted .
Well last week was first run and due to the better half coming for a ride out with me didn't really take much notice of the speedo (sorry about that officer
) apart from noting it was working ,stable and smooth operation etc. Obviously taking it easy has I'd not had a passenger on a bike for 40 yrs that was about the sum of my interest . However last night got another ride just to move but was able to look closely at the speedo and it wasn't miles out .I'd expected about 40% to 50 % error but I'd reckon only between 15-20% and I can live with that especially has the one fitted prev was a magnetic type and bounced so much it could have been a tacho! .
So basically if you're looking for a cheaper way to get a bike on the road which was only awaiting a speedo to get it legal I suggest trying one of these . Total cost was approx. £70 even less if you sort the cable yourself and we all know the stupid prices of original chrono heads . Not for the rivet counters but each to there own and who knows if you really want a "proper" head you'll be able to ride to jumbles to find one, cheers Bob
