Petrol from carbs - Rubberside down - 14-06-20
Hi folks, Earlier i had the carbs overhauled and havent done many kms afterwards. When i have the bike running there seems to be petrol coming from carb 3 and 4 underneath the carb and i think from between those 2 carbs. I turn the fuel tap off when parked up as a strong smell of petrol is there. I checked the hoses under the tank and straightned one of them as a breather hose had kink but still leaks. I did change to the original handle bars but had to put the other one back on , in doing so i was careful not to stretch the cables. The manual says i can use 91 unleaded fuel, previously 96 was used in it , would using 91 affect it at all? I have serviced my bikes myself to keep costs down and i love it, apart from carbs and engine as not quite confident enough or have enough time to tinker. any help would be great.

sounds like an o-ring between the carb on the metal joiner has either got pinched or perished, if you replaced these then make sure you use a nitrile NBR o-ring as they are less likely to have a reaction
