Dies Under Hard Braking
I know this has probably been covered before but I noticed that if I am coming to a stop, and slow down gradualy, all is fine. If I stand it on it nose the RPMs will drop and it will die. What have I missed?

There's a carb overflow hose that runs through the carb brackets that's routed through a tight bend that can get kinked - take a peek underneath the airbox next time you're under there. Symptoms as you've described are for it to happen under ermergency heavy braking.

I know exactly what you are talking about. They are the only hoses I didn't mess with. They still have the original dust and grime on them. I'll take a look the next time I have the air box off.
I have started to compensate by pulling the clutch and rolling the throttle on a bit. For me, it's too much to remember when you have cars to worry about.

I ran them straight, but I still have issues once in a while at the track.
4 or 5 times at Road America yesterday, iirc.
As stated...under heavy braking. Irritating.
Next time I'm in under there, maybe I'll try the 'pointed down' and angle cut hoses.

Something I remembered that is very important. In fact it should be a sticky.
Cut the rear hose shorter if you do this. I had the hose get stuck under the throttle stop on the carbs and jammed the throttle wide open. I had this just before a turn.
Cut the hose so it cant reach the carb stop for the throttle.

Mike, is there anything wrong with simply removing the hoses? Or actually, just the front hose.
