Managed to find it, extremely small split in the inlet manifold so it was pulling extra air into the engine. Thanks for all the help though guys!!

Athena Big Bore kit fuelling problemRecently fitted the Athena 170 big bore kit onto my 2005 DT SM/R. Worked beautifully for the first two or three days and now struggles to run. Feels as if there is too much air in the mixture/not enough fuel. Tried the obvious fixes e.g. carb clean, increasing tickover etc. Runs fine with the choke on/whilst using the throttle but cuts out as soon as it’s idling. Anybody else experienced similar issues and have any ideas as to what it could be?
