PJbanditchop Posted June 16 Posted June 16 (edited) 1200 Possible high oil pressure Hello, I'm new here & hoping someone might be able to shed some light on what's happened to my motor! I've got a mk1 1200 bandit engine in a hardtail frame. The engine had stood for 20 years when got it & had only 2000 miles on it. I've had it on the road for 2 years & 4000 miles with no problems. A couple of weeks ago I changed the oil and filter, replacing the champion filter that was fitted with a hiflo filtro one that I had in the cupboard. I then went out on the bike & after 4 miles pulled over to check for leaks, oil was being pushed out of the breather & dripping off the cooler. By the time I got it back home the cooler was split & spraying oil out. The cooler was an after market one of unknown origin but had done 4000 miles with no problem. My initial thought was a faulty filter causing a build up of pressure in the cooler but now I'm not so sure & an thinking possibly a stuck oil pressure regulator in the sump. Has anyone heard if anything like this happening? I've ordered a HEL cooler but don't want to fit until I'm sure what's caused the problem. Cheers in advance! Edited June 16 by PJbanditchop Quote

PJbanditchop Posted June 16 Author Posted June 16 Cheers for the replies, I've had a good look at the filter but not cut it up yet. The holes in the internal metal case are smaller than in the ones in the champion filter, so I ordered a new hiflo one to compare as I had the suspect one in my cupboard for a few years. The new hiflo one has much larger holes so I thought I'd found the problem, I then ordered a genuine suzuki filter from a main dealer & that has smaller holes than any of them! Quote
