Ports cleaned up but nothing drastic, running carbon fibre reeds with spacer, squish not done. Got it dyno tuned and cant remeber the jets but they are close to standard. Standard slide #3, standard clip position.
Must say it pings at Blue rock no matter what I do to it but OK at Wonthaggi, go figure?
As far as I know anything above a 32mm doesn't run an air jet, just the hole straight through, at least none of mine do?
My 125 does, IT175 did but used a 32mm.
If I'm in the shed over the week I'll have a look and get back to you.
My opinion take it to Jay Dee Motorcycles in Gisborne (0354281331) with as many different size jets that you've got and let them do it. They didn't do mine but I'm told they are real good with the old stuff.
Make sure all your electrical stuff is up to scratch. Check everything with a digital multimeter before bothering to jet. I have all the specs if you need them.
