Diesel powered?!?!

Are they injection or carbs?
If the later then drain the carb bowls! if FI then I guess the diesel might have eaten some seals in the fuel system??

Diesel won't do any harm......but a petrol motor will struggle to fire up on it.
AFIK diesel doesn't contain any solvents which are harmful to fuel lines.
Agree with gregorius, make sure the fuel lines are properly clean of the diesel.
Also, there's a fair chance the plugs are fouled/oiled up...pull one out to check.
Also (pt II) remember that diesel has a higher SG than petrol, so will settle to the bottom of the carb float bowls, with the petrol settling on the top of it. Given that the fuel is drawn from the bottom of the chamber it will be pulling the residual diesel through before the petrol..., it might be that you need to flush it through.

if you can take the fuel lines off and run thru in a bowl of petrol sep from bike but do it in order as you dont want them fouling again !

Hold my hands up here.
5 or 6 years back I filled my 1050 Triumph Sprint with diesel, from empty right to the top. didn't realise till the bike stopped a few hundred yards down the road.
Don't know how it happened as i didn't have a diesel car so it wasn't normal to pick up the black pump.
Had to get the RAC out to get the bike home, then drained the tank. went and bought a gallon of super unleaded put half in the tank, then with the plugs out, spun the bike over for a good bit to try on clear the fuel injection system. Drained the tank again to clear out any diesel returned to the tank.
Plugs back in and put the second half of super unleaded into the tank and cranked it over.
A real pig to start and when it did it wouldn't run right for a good while. Lots of lumpinese and browny white smoke which took ages to clear.
Then took it to the garage and brimmed it and went for a good long ride.
Apart from feeling a total pratt and spending hours in the garage getting it sorted, no harm done.

Yeah you tend to make this mistake only once ,done it in the work van about 10 years ago ,got 1/2 mile up a hill and it conked out and caused chaos for 3 hours:jack till I got recovered .

Yeah Redrat we've all done it - I put unleaded in my van the other week. Luckily it was about 7-quid's worth and then topped up with 100-quid of diesel, gave it a good shake and it was absolutely fine. Still felt a *** though, wasn't my finest hour!!!
