Hi

I decided to do a bit of work on my GK71F, partly to act as a learning process and also as I was not sure when the basic stuff had last been done.

All was going well, I changed the oil and filter, removed and sprayed the header pipes and changed the exhaust gaskets (what a nightmare to get back on with those half moon colletts!), changed the coolant.

I was feeling rather chuffed with myself and had learnt loads.

Then I decided to change the spark plugs (replaced with NGK - C7HSA) and have a look at the carbs.

Well the plug change was fine, but decided not to mess with the carbs just yet, just took the top off and had a look and reinstalled the diagphram as I found it as didn't fancy pulling it all apart. Now it will not start!

I have checked the spark plugs are sparking and they are. Bike sounds like it wants to start but not firing. Battery is fully charged.

Any help would be appreciated, I have read putting a few drops of gas in the spark plug holes then trying to start may be an idea to check fuel is getting through? Cannot see why it wouldn't be though as it was before.

Just so any kind person who gives advice has all the info......

I forgot to say I had turned the idle speed knob in the centre of the carbs (they are the sort where the 4 carbs are split in two and 2 carbs share a diagphram and float - not sure what they are called). I turned it only slightly, but when would not start I tried turning it tighter to the right.

I am so sick of messing and checking then having to put fuel tank and air filter on I have rigged up a little auxillary tank hanging from a beam in the garage and am leaving the air filter off when trying to start.
