If you want someone to rework those fcr's ive a mate who can weld pigs to horses, if you bring them up to Anglesey I will get them looked over.

Sorry pal only just seen this, PM on its way

See Matt Harper's site. http://www.harpers-ultrasonic.com/
He got me to do the mid-body seals for the FCR's. Turns them back to functioning carbs again.

Pretty sure mine are not leaking from the mid body seal just the piss poor repair by BDK

Gave the bike a run out yesterday, bike started fine and idle settled down nicely. Left the bike running while i went and got kitted up but on returning to the bike and blipping the throttle it was boggy and unresponsive. That would clear if i gave it a few handfulls of revs and when riding it felt fine.
About 20 mins into the ride i came to some stop and start sections and the hanging revs had returned, not as bad but its there

Ive read the above thread and it does sound like a similar issue to mine so i think its about time i bought a vacuum gauge and stipped the carbs to fit the rest of the seals as i only replaced the float bowls seals, pointless me putting on the dyno until i have this sorted.

Although the bike revs out ok it does feel a little flat almost like its lacking torque, bit like riding a 2 stroke in that you have to ring its neck to make any decent progress. Maybe thats just me and being use to a V4

If the needles and emulsion tubes are worn it will be a pig at idle and just above. Nothing will fix it except fitting new parts.

Re the FCR, there is no mid-body seal between the upper and lower half, they are joined together with epoxy. So you will not see any leaking from the body. I would suggest a phone call to Matt would not do any harm. Keihin used to sell those parts but they no longer do due to liability issues that no doubt popped up in the USA.

Idle is pretty much dead smooth though the revs just hang more often than not which is made worse if the idle speed is increased, that combined with the white plugs has to suggest an air leak surely?

Could well be. In any case if the rpm is left hanging in space it is definitely too lean.
Stick with your plan, it sounds good.

While fitting some jack up linkages i noticed this extra hole in the frame, is this to raise the rear?

If you could mount the arm there it would just snap off.
I make those too but in Titanium. http://www.litetek.co/Suspension_Arms_ToOrder.html
