It would do away with the electrics so dont need to change loom etc. It would be on a manual carb setup not the electronic throttle bodies. Its a case of removing all your injection unit & electronic ignition. Find a compatable inlet manifold to house the twin webers. Hardest bit is having them setup to run smoothly.
Im scrapping the idea of having Weber's as ive found a more cost effective way to get the same gains. I did alot of researching over the last 24 hours & have now started the ball rolling by purchasing some Yamaha R1 carbs. I found some info about taking the Weber route can cost up to a grand nowadays but by going down the bike carb route you can do it all for less than £300!!! I sourced some carbs & bought them. A company called Bogg Brothers fabricate an inlet manifold for £179. Ive found a very good step by step fitting guide so im gonna have a bash at it. No doubt the process wont run as smooth as it sounds but it will be worth it in the end
