i totaly stripped the bike today after giving it a good clean. ripped the motor out and went over it with a fine tooth comb.
i could not see any form of crank case vent or any for that matter other than the carby vents. i then dropped the oil and ganged the starter motor off along with the clutch side of the case (just for inspection) and the rocker cover.
After giving the block a good flush with gas and getting it all nice and clean i found that i needed to shim the clutch so i did that. oh i also flushed the cooling side of it too with (was amased at the amount of scale in there).
off to the hardware i went with the old o-ring from the starter. after trying a few different places i ended up with 3 oversized o-rings.
after getting back i did the valve clearances etc and re installed the motor to the bike leaving the starter off.
i slipped the first o-ring into its original place and installed the starter flushed the motor again with crappy brand new oil (cheep stuff) and refilled the coolant and oil will good stuff and kicked it over. Still leaking!!!!! not as much instaid of Niagra falls i have Niagra drip
so hmmmmmm *scratches head* out with the starter i slipped the extra 2 o-rings into the hole and then pushed the starter in again (see the bad pic- the solid black bits are the o-rings
). kicked it over and it seems to be working its abit rough i know bit i am at my wits end with this thing. i took it out and gave it an absoute thrashing and for the first time in ages no oil puddle under the thing and my boots are dry YAY
my next idea is to get a core plug and remove the starter altogether and justr hammer it in there.
burgbro there is no modified catch bottle no venting and there is no blowby i have justr had 5 thou removed from the head and new piston rings etc i never use the e-starter as the clutch in it is busted and i dont think it could handle the compression that it has with the mods anyways
