cleaning up and trying.. i realy need to buy a tap for these ..

1 hour further . axle turns again fully in :-(

so wheel back in

exhaust back on..

and changing the fuel line with sensor

as the injector holders are also fragile , best to take theme of when removing the fuel line

push forward, press the tabs and pull... works better with pliers

the new full metal sensor housing and fuel line connector , compaired to the plastics one ( very fragile , bad for fuel line )

contact... check..

and running.. nice and steady as it should

closing up the airbox and covers

nice coated piston tops

nice pistons after all

and big ass cylinders.. nice ones

as usualy check .... these are to tight so setting the piston ring caps

ready to go on the bike

these cylinder have a rear and front

as the sleeves are cut so they do not tough each other

other piston down the barrel

prepping the base gasket.. needs a sliver cut of to clear the pushrod cover base plates .. as there is very little gasket material..a little help from some sealer gasket

front one on and mounted with hold down nuts

putting the c-clips in

i expect to fitment troubles , but with bought cylinders mounted.. rear wheel up and in 5e gear to turn the crank to see if the pistons clear each other

head gaskets on

and front head on

nice big surface on these cylinders.. and pockets milled for the cometic head gasket rivets .. nice

tq down the heads

pushrod covers on.. these are one of few the o-ring is best put on the cover ad push in the head

spring loaded.. big flat screw driver to mount the spacers

nice .. markings made to lenght

the roller rockers on

and mounting the intake

top bracket back on
