Harmoniser near me

[rubberscrubber]

Cheeky t..t time
Anyone like playing with there harmoniser, would you like to demo it on my bike, can donate to your local beer charity.
More local the better, Gainsborough.

Would let steptoe have a look but to far away.

Make yourself a manometer

You could try Jim Hill here in Nottingham - our local BMW independent specialist.

Manometer

I made one yesterday, and filled with red 2 stroke, gonna fill with coloured water today and have another go, as it seemed a little sluggish to respond.

It needs doing as I have high frequency vibes everywhere, pull the clutch in and drop the revs and they stop.

I use water in mine - you've just got to watch the start-up surge as it can suck the column over the top of the 'u' (make sure you have plenty of vertical tube above the water column).

I've tried to buy a harmoniser three times and keep missing out

Do you get a good result with it then, I know its the simplest way of doing it and no calibration required to use it..

Well I do. I find it much easier to centralise a pointer on a scale and to get to 0.00 bar difference (i.e. perfect balance) on the Harmonizer than it is get two fluctuating mercury columns exactly level, even though my mercury column gauge is a commercially bought one and is damped.

I find the u-tube works fine (although it takes a bit of practise to get used to it) and its cheap and available

That said, I've never tried a harmoniser and I'm sure if I ever manage to get hold of one, I'll like it...

Ok so had another go, got the idle ok but struggling to get a balance with varying amount of revs.
Hope I'm doing it right,
So at idle I'm messing with the brass mixture screw, they are both approx 3/4 of a turn out.
And then with engine revving I'm tweaking the cable adjuster in or out, but I guess we're talking minute amounts.

So if I was say 1" out of level on the water gauge, is that massively out of balance

I don't know about a water gauge, but on a mercury manometer 1" would be a significant difference. I used to try to get mine within about 1/2 cm (my gauge has metric measurements).

Ref my above post, am I going the right way about doing it.

Yep, you are.
The main thing is to make sure that the throttles are on their stops at tickover and not held slightly open by the cables. Then you do as you've said - brass air screws for idle balance and cables for part throttle (but make sure that your part throttle adjustments don't lift the throttles off the stops at idle).

Oh yes - never touch the throttle stop screws

 

[rubberscrubber]

Ok so had another look, realised that I had zero to minimal throttle cable play, so I have wound in the adjuster at the throttle to give a decent amount of play.

I think the left stop was barely touching with closed throttle, now is ok.

I will recheck balance later on...

Thx for all the replies
