2015 R1200RT wethead non starter

So I would unplug and unscrew the Lamda probes to save removing the headers

Just unplug them unscrew them and set them somewhere they can't get damaged

Try to start the bike IF the cat is blocked there should be enough of an opening for a fair portion of the exhaust gasses to escape and it should run

If it still does not run?? Go and get two decent brand NEW sparkplugs from an Autoparts store If yours is a wet head I think the NGK number is LMAR8D-J 2013 on R1200 Wethead ??

Fit them in the main sparkplug holes and click the upper coil packs home

Does it run now ??

I have seen fouled plugs give a spark of sorts which disappears under compression The only diagnostic test for this is to fit brand new from a decent source (Not e bay or Amazon !!!)

let us know how you get on

It is possible to melt a Cat. I've seen it happen.

When I was working in an infamously awful main dealer, a tech left two coils unplugged on a K1600.

He ran it up to temperature on the bench and didn't notice to cat was glowing bright red.

Those two cylinders were still injecting fuel. Straight into the cat. And burning there. The cat was wrecked.

Did the dealer inform the customer or replace the Cat ???

No. They sent the bike out because it would be covered under warranty as long as he left the dealership.

It didn't matter that the bike ran like crap with low power. Or that the bike could catch fire. Or that the customer may fail to Overtake etc and end up dead etc.

Must protect the bottom line above all....

I’ve taken the lambda probes out and put a endoscope camera down through the holes, the cat looks ok, certainly doesn’t look burnt.
I replaced the spark plugs with new NGK plugs the following day this happened along with a new battery.
I’m now waiting for the new fuel line to turn up later today, once that’s fitted I can start cranking the bike over again.
I may leave the lambda probes out just to see if this helps when trying to start it.

Did you try the new spark plugs with the questionable fuel ?? They may be "polluted" for the want of a better word New plugs like everything in this new Woke world are not like the Old Champion N9YC of yesteryear

Just scoosh Easy start into the air filter housing Which will distribute it to both sides whilst spinning over

You reckon you have spark

You seem to have an indecent amount of compression on both sides

Not much else remains
