Engine Knock under load ?

[sdcastle]

Ok, just read through to page 20 and not found a relevant thread so going in head first

I know these GS beasts are a bit agricultural, odd noises now and again but hear me out. No Pun intended

I've just fitted a NN high wide screen and now with my flip front helmet open the reduced wind noise is letting me hear a nasty noise coming from the engine. Still pulls like a train, Tick over and low cruising speeds are fine but any accelerating and anything above 60/70mph when the engine is under load it sounds like the big ends have gone. I have a full remus system and can hear it over that. Normal? Surely not!

Booked to go "Chuff Knows Which Way Round" europe on a stag do in 4 weeks and dont fancy pushing it home!!

any tips appreciated and sorry if its been covered prev.
Thanks Tossers!

Try changing down a gear instead of labouring the engine.

Even tractors with 400hp engines have to down shift sometimes .....

I think changing down at 5000 rpm isnt the answer!!

Once its warm it will make the noise pulling away in first cant change down any lower...

So what your describing isn't an engine knock under load. It's a plain and simple good old fashioned engine knock.

It’s because of your new windshield – you are now hearing noises that were probably there all the time. I went through similar worries when I had installed a large Givi windshield. If you really started to hear that knocking noise only after the windshield change, forget about it.

cerv is quite right. A large screen will often reflect a lot of engine noise back to the rider. If you really want to test this, strip the screen off and go for a ride alfresco - I bet it sounds normal.
