T500 aftermarket banjo's NG

Post by RossB »

Just got aftermarket banjo valves not impressed,one didn't work at all the others took a lot of pressure to open up,(stiff spring or ball getting stuck) don't know if oil pump has enough pressure to open them up they were a lot of cash think there going back. That's my 2 cents!
Take care boys!

I had bad experience as well and found this Kawasaki part 16128-009 works and fits nicely, costs less and of course quality since an OEM item. Just change all if you change one is my advice.

Did you use these with success on a GT750?

If at first you don't succeed, just get a bigger hammer !

Good to know. Wasn't sure if the release pressure was the same. Obviously close enough! Chuck

I guess the cracking pressure doesn't need to be the same as those Suzuki uses, only low enough than the pump will open them? as important IMO is that the cracking pressures on all three valves in a 'triplet' (those feeding either the crank, or the cylinders) be very similar, or the single pump piston per triplet will allow oil diversion preferentially to the valves with lowest cracking pressure.
Ian, good to know re your 750! after years of fussing with two of my GTs, it turns out I always had oil delivery everywhere I should have had, but I can now see reassuring tell tale smoke in all pipes of all bikes. In both the case of the 550B and 750A the reason I couldn't always seen smoke in just one exhaust was that the SRIS system was unevenly effective. Blocking just the SRIS outlet from the 'no smoke' cylinder has evened everything up, dramatically so on the GT550B. Such is life, and old bikes :-))
Cheers,
Mike
