The four stroke engine: That's one stroke for producing power and three for wearing the engine out.

small update today, i put the cylinder back on and head with the new gaskets, i did have a little dum dum when i first put on the cylinder 1/4 way and realised that the bottom gasket was missing :roll: . then i installed all the new radiator hoses, so tommorrow i will try to put in the reed cage with the new boyesen dual stage reeds (should be innteresting to see how they work) and finally change the float needle in the carburetor wich i have been meaning to do for 6 months now, and maybe if things go well i'll be able to try and fire it up







-sorry me ingish

i got in the reed cage and set to change the float valve, i checked the float heigth with the new valve and old, the old was 11mm the new about 15-16mm, then i filled up the coolant and noticed a leak from the water pump cover(https://www.youtube.com/watch?v=Tl3euCXhpaQ) and the kill switch stopped working (https://www.youtube.com/watch?v=Tl3euCXhpaQ) BUT the engine started second kick and the valves open and close, it's probably running rich thouhg so i still have some work to do :roll:

You need to fix the over closing kipps valves , that the reason they are wrong on the closed position

There are Two ways to do it,
First way can be done at any time by simply fitting a 4/5mm bearing inside the allen head bolt shown here http://www.hallbergs.net/kx500/images/picture11.jpg
  

Second way only can be done with the topend removed {the way i do it}
This way  i put the kipps valves  on differant grove on the valve rod/ but modify the stop on rod
This way has the advantage It will keep the kipps rod in original position /angle

The black ARROW point to the way i modify the stop with a 5mm width nut


valves in closed position

i later modified this valve for better flow but this is correct position for stock valve
 

Not great flow from pre89 valves in closed position that why i modify one
