Engine dies on braking

Hey, I have kind of a wierd problem. When I brake hard, the engine just dies. It seems to be worse when the bike isn't yet warmed uo, and is also worse when using more front brake. My only thought is that somehow, the g-forces produced under heavy braking "pull" fuel to the front of the carbs where the engine can't use it. Or something like that. It's not really a big deal. When I have to stop hard, I usually just squeeze the clutch an rev the throttl. That prevents the bike from stalling. Anybody else have an idea?

 

Your idle speed too low? Make sure your at 950-1050 RPM. If not, adjust it. If you are in the lower part of the range, you might want to bump it up just to see if the bike likes it better. Your carbs are designed to work with the dynamics of the bike so I don't think your issue lies there Jas. If you pull a little throttle to come to a stop and the problem is fixed, it is definitely your idle speed. Give it a whirl. There are a few threads on this forum that were recently discussed on this topic, you might want to check them out. Good luck.

 

Does it want to die after your braking too? (when you are stopped) - if so your clutch cable might not be letting the clutch disengage. It doesn't sound like it - but just checking.

 

I am having hte same issue, very rare tho. I would adjust idle upwards a VERY small amount, as my bike would die before, but since i moved idle up like 50 RPMS it has almsot completely ceased to be a problem.

 

It's definitely not the clutch. Idle speed might be an issue, but I don't have a tach. The bracket where the tach gear goes into the engine is all busted up and the tach itself is missing. I'll try adjustin the isle speed up a bit. Thanks for the advice.

 

How can anyone ride without a tach? I can do without the speedo, but not the tach. It's the heart monitor. I know more about what is going on in my motor than from any other sensor. Good gravy lad, get your tach replaced!

 

hell over 85, you are riding with no speedo, i call it "warp speed" at that point.

ears are good.... but dont even come close. I definitly garner much useful info from my tach.

 

and the first ride of the season you forget what it sounds like... I keep finding myself down around 7 when I think I'm around 9. I use the clutch alot to train my ear - then it's mostly no gauge riding

 

I know, it's a pain. I try to listen to the engine as much as I can, though. I also know that redline in first gear is around 35 mph and in second gear is around 65 mph, so if I'm really jumping on the throttle, I know when to shift by watching the speedo.
