Hi, I'm currently working on my 91 pre diversion xj600, removing the inlet rubber carb manifolds I found out there hard brittle and cracked. Looking on the Internet i found some £100+ per set, is there anything from a different bike which would fit, I was given some new old stock ones which look the same but have a different offset and make the carbs sit too low and catch the engine and they dont line up with the carb bodies,worried now to buy some and don't fit, any help appreciated
Thanks
