M750 that Kat crashed in October 2018 is ready to run after major rebuild ,,apart from no paintwork , as painter had cancer then Covid 19 ,, hope it gets finished soon

however I fixed up my remote workshop fuel tank and a battery and bike fired up easy ,, Its running OK above 2500rpm on both cylinders but at tickover it only runs on front cylinder ,, checked sparks and plug on rear cylinder all is good ,,,, so i suspect the carb slow running jet ??? ,, carbs was stripped and cleaned in a Electro Tank and rebuilt ???

also a small oil leak from bottom of rear cylinder ???

Did you replace the tiny o rings I had the same problem and new o rings sorted it . I assume the new full degrades them as they were deformed when I changed them
