| coolent problem
i recently had my 748 serviced and its had some up and down problems with the water on it when i do a long trip it seems to pressure up the system and eject the water out of the pressure relief pipe on the second exspansion tank (between the cylinders) i have had the bike back at the garage and they said that the cap on the header tank was faulty the replaced it free of charge and i hoped that it would sort it.
I noticed that the coolent level had gone down again tho and no its doing the same thing again is it likely to have a i air lock or a blockage some where is there a bleed valve on the water system and do these so called radiator flush products work ??? or is it ment to do this and u just gota keep i eye on the coolent everyweek??
the temp never go's over 180 and sits at 140 most of the time just seems that when i do a 180 mile ride on it it ****is out all over the engine.
any help would be great |
