The petcock is vacuum operated. When the tap is set to ON or RES and the engine is running a vacuum is created by the carbs via pipes from the petcock which opens a diaphragm and lets the fuel flow. When the petcock is in PRI position this bypasses the need for the vacuum.

It is my thoughts the vacuum pipes have not been correctly installed. Th…[Read more]

A number of things could cause the issue. It could be mixtures not set right, blocked or incorrect jets, incorrect float levels or carb balancing for starters.

Have you removed and cleaned the carbs?

Hello Mungo6 and welcome.

That is a nice looking B3 you have there. does she run as good as she looks?

I also have a ZRX1200R. Like you say a completely different ride both of which are enjoyed for different reasons.

Whay electrical issues are you having?

Your not to far away from my sister in Camberley.

Glad you are enjoying the site.

Cheers

Great pictures Marko. It is good to see her running again. Have you fixed your problems OK?

All sorted

Hi KawaKurt

My apologise for such a late reply but I have been away.

This does look like you are burning to much fuel which could be several reasons, all relating to the carbs.

The first thing I would check is that the choke is working correctly. A choke stuck on could cause this. Secondly I would check the fuel mixtures are correct.

It is amazing what you are making these twins do and what great action shots with your son too. Great happy memories mate. Respect and Well Done

I am loving the look Michael but I must be honest. That seat does not look very bum friendly . . .

What a shame that is Ankargren.

Hopefully things will change and you will be able to get another 750 twin soon.

In the meantime look after yourself and hopefully we will see you back soon.

Hi Big Chris and welcome to our site.

Yes I know the bike and I also know Edmund very well. I have supplied quite a few of the parts he needed too.

We are a quiet friendly  community of like minded people who share problems and support each other to help keep these uncommon machines on the road.

I believe there was a bit of an issue when you…[Read more]

This is amazing to see Michael. I never thought your twins would ever be a vision on the race track. What a great job you’ve done.

Respect

The engine is definitely a B2 engine but the colour is B1. It is the frame that determines the model.

B1 – 000001 to 016100 inclusive

B2 – 016101 to 025700 inclusive

Paint codes have always been a big problem. We have original paint codes but there is absolutely no cross referencing to new paint codes. They are done by colour matching to original panels. If you do manage to get a colour code please share it.

Interesting. I haven’t seen that tried before. How many lugs line up?

Some have fitted G model side panels for a different look. They fit on 3 lugs.

I kinda like the 900 panels  . . .

Hi Patrickp and welcome. It is always good to have new members.

Beautiful part of the country. Was down there 3 or 4 years ago on my ZRX. Was an amazing trip.

If we can help with getting her running let us know. I have quite a sunstantial stock of parts too so shout up if you need anything.

Feel free to browse and post at will.

They are out there. I would suggest contacting a seller and asking them.

We all would like NOS. Those 2 links I posted appear to list NOS at around £200. If that’s no good then it would have to be a used one. Try getting yours cleaned up, there’s is nothing to lose.

Hi Kurt and welcome. Will be good to see you around. Feel free to browse and post.

From the picture you may have a 1976 B1. That is the paint finish. We can confirm age and model from the frame number.

Cheers

No guarantee at these but worth asking.

Used ones do come up on ebay.  I can also offer a used one.

What is the problem with yours? Normally these…[Read more]
