So this evening I established that the Vogue was running lean by checking the plug and also the fact that I wouldnt idle without the choke. I pulled out my spares engine which has the same gurtner carb but this one had a bigger jet. Only problem was it was way bigger. After cleaning out the jet I installed it and the bike will now idle. Its boggy top end but thats to be expected if im running too rich but at least its safe. Test ride tomorrow.
