GL-1500 or GL-1000 ???

Postby PedroTQ » Fri Jul 10, 2015 7:00 pm



G'day to All,

I have had my 88 GL-1500 for 6 months now, tore her down first thing to change belts and all lubricants, overhaul brakes etc. (took 3 months).

As I have never ridden a GL-1500 before I was happy with her and she purred like a kitten, but now I an getting used to her and tossing her around corners with ease and manoeuvring slowly about shopping centre car parks at low speed I am thinking that she should have more guts than she has.

I suspect that she is running on only four cylinders, and at 250cc per pot she is actually a GL-1000.

Tore her down again over the past couple of days (amongst fixing toys, dripping taps, putting up shelving for the grandson etc.)

In anticipation for what may be wrong I have bought heaps of spare solenoids, black boxes reed valves from e-Bay so I have goodies on hand for fault finding.

As you can see the reed valves on 2-4-6 bank is looking yucky, but the real clincher is the spark plugs, 3&4 look brand new as I put them in 1000 miles ago, so I suspect a naughty coil now.

Still you learn a lot tearing them down and a good chance to check the rubber hoses and replace any that look suspect, this will give me more confidence when she is back on the road again.

Best wishes to all, Peter.

Those two plugs don't look like they have ever fired at all. I would replace the coil for sure.

Man, I wish I had that much room to work. I have to do all my maint/repairs in a carport that's enclosed on 3 sides :cry:
When I had my 1500 torn down the PAIR check valve cases were a lot dirtier than those but the reeds and rubbers were fine.

G'day to All!

Thanks for the comments Guys. I will be checking the coils on assemble as I have a few spare ones as I like to buy spares on e-Bay when I see them cheap. The reed valves were a little sticky, but since I had already purchased a nice clean set for this job in mind, I just cleaned them up and fitted them with new rubber hosing.

I cleaned and scrutinised all hosing on assembly, got as far al slipping the frame over the engine and fitting the mounting bolts finger tight last night after tea, then drunkenness and tiredness crept in. :D

will try some more today. Regards, Peter.

While you have it that apart, I would seriously consider replacing the various 90 degree elbows on the spaghetti of vacuum tubing. It's only a matter of time before they go, and it's a real pain to get to them once things are back together.
