Re: Boxer engine knock Subaru

Well I just couldn't leave well enough alone. That "piston slap" didn't set right. One day I started it and the knocking was so loud I almost shut it off.It did quiet down. 2 days later I started it and there was absolutely no knocking at all.Stone quiet. Next week it's back the way it was..some kno...

Re: What Were The Worst Riding Conditions You Ever Experienced?

Just picked up my Gl1000 for the ride home in March.Halfway there on a seldom driven road was a swath of hail a foot deep and half mile wide.
Waited for 2 hours till a truck plowed a path.

That's confirmed pu-pu.
Suspect any vacuum line with that sharp 90° bend for that problem.

Re: Boxer engine knock Subaru

It's annoying but as far as I can diagnose..not a engine killer.Might move to the delco 400 15-40 for the next oil change.

Re: Boxer engine knock Subaru

I think so.If I run to Walmart and back the knock is completely gone.I can only speculate that it's piston slap.With a 172k miles,it's just normal wear.I suppose I could yank the motor and short block it but it is just a $3000 car.Already dropped $500 in it.Dont think I'll rebuild the block.Probably...

Re: Boxer engine knock Subaru

I guess I'm done.Replacing the plugs stopped the loud cold startup knock and has left me with...piston slap..Not much else to do but run it.

Re: Boxer engine knock Subaru

Maybe because these 2 plugs were loose and overheating compared to the other set the "tint"showed up first.?

Re: Boxer engine knock Subaru

Both red ones were on the same side(the noisy side).The plugs angle at about 80°.
There's no evidence of any corrosion anywhere around the plugs,just the red tint on one side.
Keep in mind,I have run Seafoam and MMO through it.

Assume nothing...How could I have overlooked this. :oops: Not 100% confirmed but I think I found the source of the knocking. I believe these are original plugs.

Re: Boxer engine knock Subaru

The car is new to me with 172K miles.Looks very well maintained and was a trade in at a new car dealership.Local shop repairs.Collage student from out of state.Had a new cat converter and CV axle within the last year or so.
Disconnecting each injector does not change the knocking.

Re: Boxer engine knock Subaru

I did that when I first picked it up.Full dose in the crankcase before the oil changed and through 300 miles of fuel.Fresh oil change with the good stuff including a half dose of MMO in both. The knock is completely gone (as far as I can hear) after a 10 Mile drive to the store and back..about a hou...

Re: Boxer engine knock Subaru

Leaning away from a premium gas fix.It has a knock sensor it move the ignition timing for that.Im also at sea level.
I think pulling the plugs may help see what it looks like inside.

Re: Boxer engine knock Subaru

No.There roller rocker overhead cam.
My older Subaru had the hydraulic ones too.
This has the normal "tappet" noise but in the background is that low pitch knock.
It's design is very much like the 1100.

Hmmm.Ill run it up on the ramps and check that.Thanks.
Should be able to locate a exhaust leak with soapy water and a cold engine when first starting.
Thanks for the tip.

Boxer engine knock Subaru

Sorry about the confusion.I can't resolve this problem through regular channels. Yes it's a subaru and is very similar to the GL1100 in design. Yes I've owned both but this is a undiagnosed problem I'm struggling with. I had to get rid of my truck and purchase the subaru.My better half couldn't get ...

Re: Fuel Pump Inop??

Also..a digital meter won't display the voltage correctly.Its just not fast enough.The voltage at the pump appears very fast and only when the pump contacts close. And then it's gone when the pump cycles. So you might see a faint blip with a test light but not a steady bright light. That's the desig...

Re: Fuel Pump Inop??

6 volts isn't enough volts to operate the pump. I'd bet that it takes 12 volts at 5 amp to get that thing to pulse. When the pump is at rest,there should be "almost"a dead short from the feed wire to ground.Its the coil resistance.Maybe a ohm or less.As soon as the power gets through the contact poi...

Re: Bike won't start

Keep in mind something about the fuel shutoff valve.
It's vacuum operated.
Check the hose feeding it.They tend to get hard and leak at the manifold.
Also..Do not open the throttle when trying to start the bike.You will loose vacuum to open the valve.

Re: No fire

The gl1100 has just 3 parts for spark. A pair of ignition coils...a pair of ignition modules and a pair of pulse coils. If you don't have spark on any cylinder,I'd first check that the coils are getting 12 volts with the key on...The kill switch is always suspect first. The second most common proble...

Low voltage low power.Use a 1/4 watt resistor.
