You are going to like those unipods.  Opens a lot of space and makes working on the carbs a lot easier.

All my bits arrived in quick time from RPM.Thanks Randy. Old air box has been removed and the Unipods are in place along with the crankcase filter. Might be Saturday before i can get my hands on some foam filter oil. Shame i can't use chainsaw oil as i have gallons of it around,i'd say it's very similar with it's anti-fling properties. Where have people located the crankcase filter after extending the pipe?
I also got the kit with all the o-rings. Where do the larger o-rings ( intake o-rings ) go.Maybe someone has a picture or a schematic that would show me the location.

Take the carbs off...take the heat shield off...unbolt the intake manifolds from the head. The large O rings go between the manifold and the head...
Take is opportunity to check the rubber carb boots for any cracks....

Will do. Thanks Pat.

Made a start on this today and have found the bike very simple to work on. I suppose having the unipods helps giving easier access to the carbs. After fitting the unipods i took the bike out for a spin and all was well but still had the rev issue.
Have replaced the inlet manifold o rings, someone had put some kind of sealant on the mating surfaces which had broken down.Maybe this will turn out to be part of the problem.Had to hacksaw some grooves in some of the carb top screws as they had been chewed but all are free and can now be replaced with new ones from Randys kit.
I am going to give the carbs a good clean (lot of crap came out of the bowls) but not change anything else at the moment. Will give it a test run after and see how it goes.Going to get this carb issue sorted before i start on the valve seals.
Is it easy to spot if the needles have worn and need replacing? Just thinking ahead if i still have the rev issue after replacing the inlet o rings.

Rising revs are gone. Not exactly sure what the problem was but during my carb clean i found a hole in one of the diaphrams and return on the throttle wasn't a snappy as it should have been.
Ended up 3 turns out on the mixture with the unipods and it runs well. Cleaning has given me a much better transition at lower revs with no bad surge between 1k and 2k.
Smoking at start up isn't bad so i'll put the valve seals on hold and settle for checking the valve clearances soon.
