hi all

right after hours of tedious cleaning, scraping , priming, painting lacquering etc finally ready to rebuild this engine, have a compresor on way to replace stem seals... so engine rebuild

totally new to this and firstly must thank all on here been a great help ( extra thanks to bryan j , anything he does not know about these bikes?)

ok all surfaces to be mirror clean, can you guys give me tips on rebuild, few things i am confused with ie order to rebuild, scared about missing a gasket

confused about cylinder sleeves at base do these sit inside base gasket or around the barrell and pressed down

base and head gasket look the same? is base more paper?

tach drive gasket ... please explain in lamens terms

also position of pistons .. is there a set position

have included some pics ( apologies a bit blurry on a couple)

maybe usefull to some to show what you now get

Got any better pics Mike? I've tried blowing them up to [width=600] which is best for this forum but they are too pixelated.

heres a link to full sized photos if that helps steve

Head gaskett has 2 6 mil bolt holes sticking out in front of and rear of camchain tunnels and metal rings round piston holes plus is far heavyer duty to base gasketts, there are as I recall 4 X O rings lodged around the bottom of the cylinder liners in a groove between the liners and alloy casting. There is a seal inside of the tacko drive (inserty thingy) and an O ring on the outside.

If you paste the "IMG Code" from Photobucket into your post, you'll get the pictures direct.

I've edited your post to show.
