Need help with my CB1, NC27

[RhynoCZ]

Hi, today I fixed my CB1, there was broken hose right behind the radiator, the hose I used was some average piece of rubber, I think the hose I used was ment to be a fuel line. When I fixed it, it has less power in high revs than it used to had. It sort of hesitates when it gets over 12500rpms. The problem is that the hose is too solid and it breaks the bending, it makes U shape there.

With no hose there, bike sounds like it had hole in the exhaust system or something like that and it has no power.

My question is, what type and dimensions do I have to use, to get back its power again. I was going through the manual but I can't find it.

Thank you.

I`d phone David Silver spares and ask for the exact hose

Shouldn't affect performance being a radiator hose, is this a fuel line you now talking about?

Hesitation is usually down to the fuel pump
