I made a needle out of a coffee stirrer for my CB250RS! A bit agricultural but worked for me. I just stuck it on to the remains of the original with super glue if I remember correctly.

like your repair ian, i'm a big fan of upcycling.... my problem is, i cant see a way of removing the bezel without wrecking it.

If the bezel is crimped on as most are you can sometimes get them off with end cutters used carefully although I always manage to mangle them. The Honda was easy as it didn't have a bezel as such, everything came out from underneath.

Flippin heck Steve.....that's harsh. Although it will be a very good job. Have you tried fleabay or Jauce in Japan?

Addendum .....how about DK Motorcycles in Newcastle under Lyme?

I have a spare tacho from the instrument panel I fitted to the B'Zuki if it's any use to you - yours for the price of postage and a pint. Let me see if I can find a pic.

that's bloody good of you Ian.... is it the same dia &  depth as the srx model? i.e. would it be a direct swop or require some 'modification'?

let me have a go at opening this one up (i have 2 with broken needles, so i can afford one cockup) will let you know how it goes

cheers

I'll check the diameter and depth for you today. As far as I know it's on working condition - it was sold to me as such but all I needed was the mounting panel so it's surplus to requirements. I have the matching speedo as well I think.

Both instruments are 82mm body diameter - 92mm over the bezel. They're 54mm deep below the bezel not counting connectors etc. The speedo has a right angle gearbox.

it's amazing how a rather expensive quote for a repair concentrates your mind....

i woke early this morning (too bloody hot in bed)... and lay there thinking about maybe fixing the tacho myself. as i have 2, both with the same problem, i figured if i bu55ered it up i still had one i could get fixed professionally.

so, i formulated a plan.... plan A, (there was no plan B)

i'd grind off the lip at the back of the bezel then i could pull the whole lot apart, make a new needle, clean everything fit the needle reassemble and glue it all back together.

amazingly plan A worked a dream... made a needle from a bit of a coke can, painted with red hammerite glued on with a spot of araldite, sprayed various bits with matt black, glued it all back together with clear sticks like sh*t.

hey presto ... £145 quid i can spend up the pub :-)

2 hours start to finish.  now, maybe i'll fix the other one, and make a smaller needle. then flog one of them, 'cos i was looking on fleabay and they're listed at £100 + .... more pub money :-)

staying true to TC approach to things , it's the only way  ;D

but thankyou Ian for your very generous offer, which was also in the true TC tradition

i'll be tackling the second one over the weekend, i need the funds as i've been and gone and done it ....

ordered a couple of carbon fibre side panels for the final SRX6 build ... which is way behind schedule as frame and other stuff still not done (i made the mistake of saying 'no rush guys' ..... you think i'd have learned by by now)

Excellent work Steve.

Never Say "No  rush" even if you mean it  😂....

81K Km is maybe why the old girl is smoking like an old tug boat!

and still puffing well after a +50thou rebore and NOS piston/rings

early days, will see what it's like after i've run it in a bit.
