Any recommendation Guy’s

Guys I need to get my 1700 x-flow seven tuned up, the Webers are running too rich and a good tune up is in order

There seems to be 3 Companies in my area with a rolling road.

Anything to do with tuning I go to The Guru Roger King. Can't be bettered. Can be found at www.rogerkingengines.com. He works with The 7 Workshop in Herts, so a bit further out, but well worth the trip.

If they were good once and the carbs are not worn then it's just a tune up with a twiddle of the idles and a carb balance you need. Perhaps a clean of the filters could help and Halfords/others sell the kits to do this.

 

There are various guides to tuning DCOE's on the web. The inital set up for the carbs in the build manual is another.

It is not rocket science.

I regularly do it for club members at the meets.

 

You need to practise. You can't damage anything bar brutally

overtightening the idle screws and ruining them.

Listen very carefully to the rev speed and observe the vibrations.

Adjust each idle at tick over for highest rev. I go in or out 1/4 turn each time and listen. Wait 10 secs for revs to change.

When at fastest speed, richen 1/4 turn. Then do the next one, etc.

After than rev her up to 1700 rpm. This is the critical progression zone. If things are a bit 'lumpy' or 'fluffy'

as you rev then try richening each idle screw a bit say 1/8th to 1/4 turn.

 

When all idles are done, balance the carbs using the lead trumpet of each carb. A piece of hose can help you hear the suck or a posh bit of kit, the Synchoniser, will do it.

You can hear when the carbs are out of balance and twiddling them will bring them to a sweet zone. This is usually the best balance point.

With the synch tool you can try balance at different revs and check....

It is very satifying to have in tune carbs.

 

Good luck in whatever you try.

Forgot to say the prev owner of my VXC HPC used Misbourne motors

for rolling road and a compressed hydraulic tappet change.

He was happy with the service.

 

Ask for Guy.
