It's a funny old world. your neighbours don't like you revving up at 9am on a Sat morning. Last night at 11.30pm Paul and I were still in my workshop at home drilling, sawing, filing and generally making lots of noise. We were thinking about stopping 'cos it was getting late, so we started packing the tools up, only to hear matey across the way going at it with the hammer drill. Oh well, this is Thailand after all!

No wonder nobody's complained about me revving up the Stoner replica in the house

On the RC valve subject. The only 'proper' way to do it is to pull the pipes off first and make sure that you can mark the position of the valves at their fully open position. Then when you're doing the rev up test you can plainly see what's going on. Then you can fine tune it on the dyno, like Steve does 'cos he's got one in his kitchen.

The F3 ingition I'm running on the 300 goes fully open at 2~3000rpm, so it's a breeze to set up. The NF5 PGMII doesn't have this option and needs the valve checker.

By the way Steve, I presume from your post that you got the checker working?
