Rev counter mount

[ranton_rambler]

I have bought a cheap electronic rev counter and am struggling to find a place to mount it at the moment.
Any photos of how the OEM version was mounted? I think they normally go on the right hand side of the handlebars where the only likely points to pick up are the fork cap or the headlamp side screw.

What bike Ian ?

My bike is a 175TS which would not have had a rev counter, so I suppose I am looking for how it was mounted on the contemporary sporty versions. Elite or Mach 1 I think.

Mornin' Ian, from a chilly -2°C, but very bright Perthshire.

Attached is an image of a Ducati MK3 250cc, with the accessory tacho mount using the single right hand side bolt for the headlamp shell as it's mounting point.

I'm sure that many moons ago there was a discussion and possible replication thread about this bit of tin work on the forum. So, a wee search using the 'Search' window top right, might prove useful?

Good health, BillR

Any help? On a Mach1

Thanks both.
Those seem to be the same type and use fork top cap and headlamp bolt.
I have found a piece of thick alloy plate in my garage so I think I will make something to pick up the fork cap. The electronic unit is quite lightweight so I think it will be ok with a single mount. I will try the unit first though, to make sure it works before putting the effort into the bracket.

PS Bill - about 5C here in the middle of England. Sunny though!

By chance this Mark 3 popped up in a For Sale ad. Seems to be a different version using the central nut.
I’ll see if that might work better but might obscure the speedometer in the headlamp shell.

I cobbled some wiring up today and the cheapy rev counter seems to work OK. I'll sort out a proper mount and tidier wiring when I get chance.

It raises a question - now that I can see the engine speed what should the idle speed be on 175? I have just set up by ear at the moment which seems to be about 1500rpm on the gauge.

I don't know what the idle speed should be, but I like mine as low as possible as it gives better gear changes.

Cheers,

Aye Ian,

Ducati engines are no steam engines. So, whilst a slow tickover from a long stroke British single may sound therapeutic, it isn't going to happen with a Ducati single. Besides, how long do you spend at tickover? I understand that the England-shire and Scottish conurbations are getting bigger and the ever increasing 20mph zones, mean it is more likely, but overall the engine doesn't sit there for long.

My 450 , with it's past habits of spitting back through the carb, or blowing it off, makes me set an even tickover, between 1,100 and 1,300 rpm. Yes, I can get it to go lower, but when moving off, with my gearing of a 17t and a 41t, the revs need to be up and above 2,000rpm due to the relatively short stroke and large bore of the engine, coupled with the gearing.

Better off to have the engine running at a junction/traffic lights/roundabout than it coughing and then having to hop off to push the beastie to the side, or give it a swing, in the hope that it'll start first prod, whilst the electric car GT stakes kick off all around you.

Good health, BillR
