Hi there,
I have a problem with my 'New' '90 Turbo. It is only boosting to about 1.2 Bar
Had a read through Clarks garage webpages and a search on here and it looks like the most likley issue is the cycling valve. - I have checked the pop-off valve and the wastegate exhaust for leaky wastegate issues.
Actually When I tested the pop-off valve there was no flow between the pipes, but blowing into the top one did cause the air to leak out of the vacuum tapping on the top, is this correct operation?
I have a pipe clamp on order so I will test the cycling valve operation when that arrives, if it does turn out to be a problem of wastegate control, does anyone have suggestions on how to trace the fault to either a poor signal from the KLR or a faulty valve itself? - I didn't really 'get' the instructions on Clarks about listening to the valve with a stethoscope
Thanks for any suggestions, need my booooooost back
