my m8 swaped his oil pump hose over for 1 of them clear hoses u get of ebay and he can get rid of the bubbles in it when hes rideing it you can see a white thin line of bubbles in the pipe hes sat their for 10 mins with the bleed nipple off and still no luck should he try bleeding it with the bike leaning againts the wall so it not as much on a slant any help would be great thanks
There is obviously an air leak some where mate. He'll have to strip it down a again and restart. Make sure all clamps and hoses are securely tied down. I usually bleed the bike through the engine. Since it is not a closed system it won't make any difference. But best to do it properly.
loosen the bleed nipple till oil comes nip it up then run the bike with the oil pump pulley held wide open with ur fingers just keep blipping the throttle until it pushes all the oil thru with the bubbles, but as said make sure all the hoses are on tight so it can draw a good vaccume on the oil line
it wont make no difference if the bikes at a slant or str8 up
