often wondered what the humble bantam was capable of it does sound quite busy past 60mph
the racers manage around 10,000 rpm
have to wait for a nice windless day to take it across the very flat marchlands road
I had a honda cbr600 a few years ago that relined at 15,000 rpm

If you are going for 10k, will you be have a recovery vehicle trailing you? stick-poke wink

Mind you, my YBR250 has a rev-limiter that comes in at 10k - and it's like a sewing machine all the way up to it ninja

1956 D3 running, lights to sort. 7 other bikes in the Barn. 1950 D1 engine being rebuilt (slowly).

Thanks for posting that - I've ordered one. Will be interesting to know just how hard I am working the bikes...

1970 B175, '49 D1, '66 Spitfire MkII, '57 Venom, '76 Cb750K6, some of which are actually complete & working...

Im only really expecting around 6K as the engine is a mix of 4 models
and it is slightly higher geared because of the 19” rear wheel
just curiosity really as the rev counter only cost a few pounds
which i bought for testing a petrol leaf blower which was behaving oddly

what sort of RPM did you get Nick?

Hi mike...didn't try it flat out still running in after a re-bore...seem to remember 40mph gave around 4000rpm in 4th.

Should have made a note really.

I've just picked up one of these - any suggestions on how you've all fitted it?

With me 4 coils of the wire pickup around the HT lead...clip the meter to the handle bars....it was only a temp lash up as I just wanted to see what RPMs I was at in the cruise.

I do know they are very accurate once set to the correct 2 stroke setting.

Had one fitted to my microlight in a semi permanent way...very useful.

I just stuck my one on the tank with 3M sticky pads, not really meant to be a permanent fitting

Thank you both!

Sticky pads are a good call, I've some for car number plates that will work. Nice flat space on the D1 tank for it too.

This'll be interesting 🙂

Perhaps I should have been clearer
the 3m sticky pads I used were the reusable type that you can peel off and use again, really weird stuff
number plate pads are almost impossible to remove from paintwork, would hate you damaged your nice paintwork by my suggestion frown

That's kind of you to say Mike !  I'll have another look at the pads I have then - the number plate ones I have don't seem that strong, they seem to peel off quite easily - but I welcome the caution and will experiment with them first.

Be careful with those sticky pads. The ones I have for sticking number plates on will take the top coat off anything if you try and removed them.

Current bikes......1958 D5, a 77 Suzuki GT250 and a 77 Honda CB125S. I have a B175 in the workshop and a 76 Honda C90 waiting its turn. A 1980 Honda CB400N waiting for MOT.  Everyday ride is a 2011 Harley Davidson Sportster.

First ride with the rev counter tomorrow 😊

If it stays on ...

What revs are every getting? At say tickover and full throttle?

I set mine up wrong - it was reading 1400 revs at tick over 😳 I know I tend to give it a high tick over, but I thought I'd better check.

looked at the manual again and it said:

1 1 cylinder 2 stroke

I'd gone with that thinking I have a 1 cylinder 2 stroke bike...

but number 2 reads:

2 1 cylinder 1 stroke

Ahh - the first one is a 4 stroke firing every 2nd stroke - the other is for me.

so mine must have been around 700rpm tickover - but I'll report back tomorrow.

I can't figure out what setting nick - 1 and 2 are too high, none of the others look right either. You were missed today by the way !

Your electronic ignition aren't you Steve...my Rotax 2 stroke fires twice every revolution...cant remember how I set mine on the bike but prob setting 01.

Bog std ignition I would say set it to setting 02 but with your electronic it maybe 01 fires twice per revolution.

How many turns around the plug lead have you Steve....I found it varies from application to application.

Gutted I could not be there...was it a good turn out...did the D1 behave....looking forward to any pics.
