BobaChris said:I have a cb900 supersport I'm building and putting GSXR carbs as well. Curious to know if you put any copper piping in the marine tube. I know the guys on CB1100f forum put inserts when using radiator hose.
Like the build so far and can't wait to see the outcome.
I'm on the cb1100f site as well but dont post alot. These carbs are direct lift flatslides not the CV semi flatslides. Therefore I don't think I'll need the copper inserts. Usually they are needed to support the carbs and to minimise the narrowing and flexing due to the high vacuum created by the CV carbs. On these the vacuum wont be as great as the slide opens as you turn the throttle and so the vacuum is not as great. Also I'm going to support the carbs as well.
I used GSXR CV carbs on my last build a CB750 but I used 1980-82 GS1000 carb boots not rad hose.
