Glad to have my 13 back at last.

Nice avatar Z1300rider! Looks like a pink face with a pair of weird eyes and big yellow teeth - wearing a fur coat! Definitely looks like from somewhere cold, hahaha
What's the story behind it?

Hi Stan.

I think those weird eyes are nostrils and the fur coat is a rat. :woohoo:

Don't say..... Eyes poking out of nostrils and wearing a rat for a coat!?!?!?! Live and learn, at least if they hunt me at night I will know what they are! :whistle:

Your '13" is bright, shiny and runs, so meets with my enthusiastic approval. Nice !

She still has a slight spit through the carbs

This is typically a blockage in a idle jet and/or the transition-jets. Consider this and solve the issue.

I agree with scotch - this one works!! No problem with having this my official endorsement.

It’s a Predator 6 into 1 short system onto which I had a widening extension added by a local tig welder, and a Black Widow end can. The pipe sounds great but is not that loud from afar. I am sure the baffle can drop out unexpectedly when required. The pipe and rear peg support I made from 10mm high grade aluminium which I ran through the polishing wheel.
