just curious, would the starter motor even have enough power to bend it?

Sorry Ralph but I don't remember reading that anyone had said with any certainty that the conrod had bet, most of said MAY have.

We were just going on the infomation provided by the OP and the title of the thread!

It is possible to bend a conrod buy turning the engine over if one cylinder is hydrolocked, Honda CBX1000 were prone to bending rods if the fuel tap was left in the on position, as it filled one or 2 cylinders with fuel. Staring the engine would result in bent conrods, as YC and myself correctly pointed out you cannot compress a liquid.

Honda cured this in later models by fitting an electric fuel tap.

Its difficult to diagnose from a distance, but its not all bollox.

thanks for the replies and suggestions.
Nobody offered any other possibility. I'm not surprised the OP feared the worst, the thread reads like a conclusion to me too

The CBX1000 was in inline six. It's most likely to have bent a con rod when the the hydrolocked cylinder was not the first in the firing order when the engine started, so the torque required to bend the con rod is most likely to have came from other cylinders firing before it, not from the starter motor. This is a twin and the OP has told us that the engine never fired, but stopped the starter motor immediately on him hitting the button. What's more the con rod connected to a 165cc cylinder in a 1000cc six, is probably going to be a lot lighter than the con rods in a 325cc per pot SV.

Compression test will tell for sure.

I am sticking with initial thought of oil in carb being problem.

Couldnt get a comp tester this morning, will try to clean the carbs this morning and see if that makes any difference then venturee out later to try and get a comp tester.
Any particular bits of the carb i'd need to pay attention to?
Thanks for all the suggestions folks.

Pilot jet and air jets.

You got compressor? Just blow through holes, no need to take off bike just be careful because you might end up wearing some petrol

cheers husky - appreciated, I'll get a comp tester first and see what the readings are like.

just had a quick look on the net, most of the comp testers come with a few thread adaptors, what size is a sv plug hole?

unfortunately i dont have a compressor, i'll just get under the tank and see what i can get to....
