My G seems to misfire quite badly when its first started up cold, after about 40secs it settles down and runs perfectly, anyone else experienced this?
sounds like same issue spaniel and dk have!
Robin- the 1341cc engines are very 'chuggy' from cold, mine always has been, as has Andys, due to the expansion rates of forged pistons in comparison to stock cast ones, just more blowby until they're warm.
oh ye - race spec forged pistons
