Sounds like the end of the road for my GS ownership

Santa-2512 · Jun 26, 2018

Well seems like the Lemon has had a final attempt to end my GS ownership.

First full week back on the bike - A nice run to work today, and this is what i get on arriving home

valves/valvegear?

fizzer · Jun 26, 2018

do they not have a tiny push rod in about an inch long thats prone to failing

patzx12 · Jun 26, 2018

Sounds half crank speed. Cam or tappet or pushrod. Pull the cover and have a look

Never the end of the road ...... There are talented businesses on this site which will soon sort out ... Any problem.
I appreciate the distances involved, but well worth the effort

Santa-2512 · Jun 26, 2018

Just had the RH cover off,

All looks ok inside, no obvious bits falpping around

all valves clearances were loose at tdc and tight (not checked ) when on open and close

just going to torque it up and have another look when its running

Nutty · Jun 26, 2018

Sounds even more like a tractor now!

I hope you sort it

Pukmeister · Jun 26, 2018

Are you 100% that you were on compression stroke (with all valves rocking), and not exhaust stroke when checking clearances ?

Leaking head gasket, barrel base gasket or blowing exhaust gasket, loose secondary sparkplug ?, youtube video clip has terrible audio so hard to tell normal clatter from unwanted noise.

Did this noise just start suddenly ? Any oil warning light ? How hot is the engine ?

I’m genuinely sorry to hear this, despite the previous banter we’ve had.

In all seriousness, talk to Mikeyboy. He really does perform miracles on engines as you already know. It’s worth getting a quote at least.

Tappets loose was best guess, it was at tdc follwing inlet valves closing - HG not leaking nor ex gasket leaking pretty sure its not loose lower plug - ( i will check later)

If you play the clip through headphones you'll hear it lol engine was at normal temp 5 bars ??

its like a clacking / clanging noise everytime intime with an inlet /exhaust stroke.

Lots of YT vids with the same type noise . but not have a defined solution

IF thats waht those bloody pushrods sound like when they fail!!! jesus

do you know if they can be done in situ or is it head off / timing redone ??

Cheers,

I know where your comming from .. no worries

Mikeys about 300 miles from me so its a big old journey to get up there...

ive also got to factor in the cost of a repair against market value of the bike ..

not sure what to do at the mo .....

From the vid clip it sounds like both sides though

I’m only at Melton Mowbray not Aberdeen

Prob cost around £150 to get a courier to bring it up

interesting- when you near the bike , it sounds like mainly the right, and its more pronounced RHS its no tappet or injector tick thats for sure-

its like a fullblown clanging noise but almost like a big end but not big end if that makes sense?

200 miles

can you do the pushrods with the heads in situ?

or do you lose the timing when you take the rocker assys off

Wolfgang · Jun 26, 2018

Steptoe's in Kingston Vale.up the London end of the A3 from you.

Pukmeister · Jun 26, 2018

I'm wondering if your cam timing has somehow altered, allowing piston to valve contact.

How does it start, is it laboured ??

If it wasn't for bad luck, you'd have no luck at all mate !

Heads can stay on ,but I have a suspicion you’ll be looking deeper,
Did it come on suddenly?
Edit ,,It’s not something daft like a locknut coming undone is it?

mikeyboy · Jun 26, 2018

I’d be checking ,
Valve clearances ,if excessive .why
Camchain blades,
if the above ok make a decision how far to go
As then the heads and barrels will be coming off.
