OK first things first

99 curvey stock apart from can and cosmetics.

Went out this morning as have day off on christmas eve went to start the bike and then .........

One compression stroke then clink now will not even turn over .

Check that is out of gear and that the cut out switch: all ok .

checked the voltage of the batery 11.47 with load of starter and just below 12 with out .

engin is not rotating any help please.

It sounds mechanical but as am an electrical engineer not to good with nuts and bolts......

I have a feeling its going to be expensive. IE engin rebuild if so will be ****ed you pay your money and take your chances.....

Any help would be GREATLY apreciated

Sorry havent had time to spell check as have the raving hump.

Charge battery, should be about 13 volt or so.

Stick it in 6th, try turn it over by pushing the bike forward, if it feels normal then charge the battery.

Mine will start down to about 11.5v, less than that it won't crank.

Cheers for that matey its defently not the battery as have stuck a dummy on load and it passed. I have also used a tong testers around the + cable on the feed to the starter motor.

The motor hasnt flashed over and seems to be free

That battery voltage is way too low at 11.47 Volts

Yea, have a go with charging - I had a similar problem when my voltage regulator-rectifier died

Hovis could be right, switches might have frazzled out

Have you checked no wires have chaffed?

Do the lights dim when you try to start? If not then the starter isn't trying to turn the engine - that would mean one of the ignition circuit cutout switches(sidestand/clutch) is faulty or the starter is faulty. Have you tried the previous suggestion about pushing the bike in 6th to check that the engine isn't seized?
