OK...Update time. The monster has been great after you lot helped me patch it back up!

But now I have fiddled with something and it is not great.

I replaced the fuel line from tank to filter and from filter to fuel tap. I could not get an L-shaped filter so used a normal straight filter.

The fuel lines are quite long so they have smooth curves. Also took the tank off.

Now it runs but is down on power. Feels like fuel starvation!! I ran it with the tank cap open and this made no difference. It won't go more than 60mph and this takes some serious run up

Any ideas?! Can I run a line direct from tank via a filter to the carbs to rule out fuel pump or tap?

Any help would be much appreciated! Supposed to go riding at the weekend!
