Got a dyno run for my H1 to make sure she is 33 and thought i'd share the results.

You're running rich (I think I've got that the right way round) on your A/F up to about 5k. Probably not worth fiddling that much if you plan on keeping the bike and derestricting it in due course but I'd have another run after derestricting and if the fuelling is still out have it tweaked. It will be causing boggy running at low revs. Pilot screws possibly set wrong.

Hi mate, can i just ask how is this restricted? with the carb plates?
Cheers!

Always wanted to see a dyno run on a restricted zxr400. Remarkably spot on isn't it!

Hi guys, she's restricted with plates between the carbs and the cylinder head. She was restricted when I picked her up and she ran nice for the 200+ mile ride home...I was still used to my old 125 so didn't really notice the bogging much :/. Now that I've oiked out the plates and replaced the air filter and exhaust system I am noticing the bogging like hell!!! Just saving my penny's for a rejet and a tweak on the dyno so hopefully she'll be a bit better soon
