    Oil cooler lines and oil pressure

    Ok guys.. here is one for you. got my new carbs from sudco and the bike runs great and pulls hard.

    while tuning I blew a new oil line apart at the bypass block on the top of the lower motor. what a mess..

    I cut out the piece and went down the road. again the line blew.. nice oil trail to my house now. ..

    the bypass block is one i have had for years but the cooler is new. my thought is the cooler cant handle the flow at speed. But i don't think the bike should build enough oil pressure to split the line anyway ?

    when i set the valves i had the bike running with the cover off to check and it has a very, very good oil flow with the cooler on.

    The line has a production date of 2/15/15

    what pressure should a 79 gs 550e have anyway ?

    Im thinking 35 PSI ?

    it a wisco 635 kit with cams, pipe and other related parts.

    No, 35 is like 5 times the max pressure which is 7.1 psi at 3000 rpm.

    1983 Gs1100ESD, rebuild finished! Body paintwork happening winter 2017:D

    I would rather trust my bike to a technician that reads the service manual than some backyardigan that THINKS HE KNOWS how to fix things.
