Are the float needles new? If not, replace them. They could have dried up while sitting out.

Watch these.

No they were the old needles and the carbs have been laying off the bike for 6 months ,thanks for the video links !! Btw how could I check the float level when I get the new needles ? I don't think that homemade tool will suit my carbs

I had another video where they used a digital caliper to measure the distance for the 7mm. I'll search again to see if I can find it.

This is a great video. Go to the 32:00 mark for the needle valve and float if you don't want to watch the whole video.

To say I'm pissed off is an understatement
New needles and seats arrived and fitted them this evening , I measured the float height also and it was 6.90 and 6.79 ( supose to be 7mm) so I recon it's pretty ok ,fired her up and was running good , I went for a couple of short journeys (about 2 miles each) and she seemed to be idling ok tried to die out a couple of times but seemed near enough for a tuned engine , blip of the throttle and she settled down again , turned her off and couple of minuites later the gurgling started again , hissing and sizzling like before , I started her up again and was flooded but cleared again , I stoped her again and couple of minuites later tried to start her and was beat , I'm going to burn out the starter , seemed to be firing on one cylinder so I gave up , I have tried everything I have thought of and what yous guys though of and carbjets.com says so what does that leave me with ? I'm going to get a motorbike guy to step in here , I was with him years ago , he's old school and imported US bikes years ago and should know his stuff

well I phoned the local bike mechanic and explained all that has been going on and like yous he jumped in and said it was the float needles , well I explained that that was mentioned and new needles and seats were fitted but still the same , he thought for a minuite and said does the bike have a petrol pump, yes it does I said , well there must be a fault in it causing it to be putting up to much pressure ,,, he said if its not cutting out at the required pressure it will push the fuel past the float needles ! it made sense to me and explained a few things , well I bypassed the pump tonight and did my run around and came home , the bike sat for 10 minutes with no sound , I give the starter a blip and she fired up instantly , I turned her off and 5 mins later the hissing of fuel running into the cylinder started again :-( , I'm beat AGAIN , I'm going to drop the bike down to the guy next week and let him fix it ! the barsteward is possessed ! I have mentioned a few times before why I didn't want to mess with the carbs/airfilter and now yous know I was RIGHT , never again :-(

Its fixed !!
this morning the guy phoned me to ask if I knew that the bike was restricted ? never knew , it seems that there was metal washers inside the carb boots (I think I remember them but thought they were legit) well he asked me why did I blank off 2 pipes (one each carb) I said I was following instructions I had seen on the net (leave the 2 black plastic pipes open and blank the other 2) well he said I think they are meant to be open !!! he said give me another hour or 2 , he phoned back this evening and said its fixed and the bike if running great ! I blanked off 2 pipes that should have been left open , he said that after the bike stops that the heat from the engine is going to rise around the carbs and the fuel has to vent from the carbs but with me blocking the pipes it was not able to so was causing a vacuum with the heat of the cylinder , fuel and no air it was sucking fuel throught the needle float trying to get air ! (for example , if I put my hand over your mouth so you cant breath where do you get your air ? you will breath through your nose !) in my case it was pulling in fresh fuel trying to get air ! so I'm to blame :-) I must have followed tj stiles video wrong
I never got to lift the bike yet as I was busy but hopeful get it tomorrow nite
