You are putting me to shame Lee! It's looking good.
I must get on with mine....

getting there if only i wasnt distracted by a leaking 250RS....
and had more garage space at the folks, damn living in a flat!

having seen some Carbon fibre work on another forum might look into some trick bodywork (front mudguard belly pan etc)

Well another spring is here and havent moved it forward much....

i have a bit of a dilemma i purchased some reproduction F3 valves from charles some years ago which i havent fitted yet.
the question is do i go through the effort of making the changes to use them for a bike which is going to be used for Sunday ride outs and the like or do i sell them to someone who can make use of them......

Or you could put them in how they were designed to go....



That would give you two full sets of valves

i was a little lost reading the other thread about how to properly use them
and also the engine is just a 1 rather than an S

This says change both cylinders to the kit parts (yeah dream on) change both ends (resonator side) of exhaust valve to the kit parts, moreover use the centre valve as a spare one because it is the same one as a standard automobile. Pay attention to the fitting of right and left valve.

So, according to this you use 2 standard and 2 kit valves - would be good if we had a kit cylinder - but I don't think that's going to happen.

I don't really speak jap but I know a man who does

Hi Salty,
Not many people with F3 barrels, but changing the outer valves is the easy option.

dont think im going to bother mucking about with the F3 valves.

rite then moved it out from storage and into a place i can work on it

would anyone happen to have a top rad mount kicking about which isnt mullered and a rad guard?

cheers

Lee

ok some progress made

better rad and guard fitted and all the pipework fitted.


need a new clutch cable
a temp sender as the one in the engine has the tang broken off.

btw does anyone know how firm to open the throttle it snaps back nice and quickly but feels a bit heavy opening? might be that i have been riding the 250RS for too long as that has open and return cables for the throttle?

my guess is take the throttle cable off and wash it down inside with wd40 and then use 3 in 1 oil to lube it up. ]as long as the cables have no fraying on them, it should snap shut.]as the throttle bodies have springs on them. [also route the cable correctly]
but as you say, the kr1s does,nt have open and shut cables' .

you can solder a wire on it.

squirted WD down the cable and it feels better but still feels it needs a reasonable pull to open the carb slides, they do slam shut nicely however
