Some months ago I was on my way to Lauwe in Belgium for the Buell meeting, when as I slowed down on the M20 for 'Early Arrivals' just before the Eurotunnel, I noticed the oil pressure light illuminate but flickered before finally going back off as revs were increase to approx 1500 RPM. At idle the oil pressure lioght remained solidly ON. As the engine was mechanically very quiet, no doubt because Tubbs :worthy: had only just put it together approx 800 miles earlier, I naturally assumed that it was a dodgy oil pressure switch. When I got home, having covered about 400 miles and a mad thrash following Banjo, I fitted another new oil pressure switch, changed the oil and filter and was amazed to have the same symptoms repeat itself. Another oil pressure switch later, same thing so time to get Tubbs to check it out.
But prior to that I had already checked oil flow through the Metmachek oil tank (more oil capacity and better heat transfer) which flowed very freely, even at tick over, already fitted with an X1 oil pump with uprated gear drive and correctly aligned. Oil temp normal and still nice and quiet at all revs.
Any ideas Peeps?

No.......but worth looking at the oil filter check valve.......this valve is designed to stop the filter draining when the engine aint running but it also serves as a 'restrictor' at low rpm and maintains enough pressure in the filter housing to open the OP switch.

Thanks Maz,
That would make sense. Is this an item which can be replaced or refitted? Is it safe to continue to ride as these symptoms still persist when the oil is up to temperature and at 1500 rpm or less?

Many thanks

Mev

I wouldn't be using the bike until this is sorted........take the filter off and unscrew it's mounting adapter......the check valve is located behind the adapter, the plastic ball valve has a spring behind it and seats against the adapter.

Maz, I take my hat off to you Sir. you were indeed correct in suspecting my problem was the oil filter check valve. It has taken me this long to test your theory because, as we all know, the weather in this country is crap!
after a goodly thrashing and a slow drag through the local town the oil light stayed off until the end of the ride. And a damn fine ride it was after stuffing a lotus and a Vauxhall vx220 down our local biking route (A32 to fareham), Ha! :twisted:

After a thorough clean of everything, the plastic ball valve was given a light buffing and the spring was given a slight tweak. In an ideal world I would have replaced these items but I am understood that they are not a spared item from HD. all said and done I am relieved it now is back to normal and a big thanks to you 8-) :maz:

:yup:

For future reference, I think the spring is 26436-90A and ball is 26437-86B.

And you (Mev) have an email from me :D
