dies when it wants
 

Hi all.. Heres the problem, I have a 1999 hawk and it dies when it wants, turning a corner or just at idle. Seems like the ignition is turned off when it stalls, not like a fuel problem. I was thinking I would ask if anybody has a place to start or has had this problem ?

If I was a wise man, and that im not, it almost seems as if the safty for the kick stand is shorting out ?

Well any help would be great...Thanks in advance...

You have hit a very good place to check.
If you have a multimeter, measure continuity across the terminals on the switch when operating the switch.
Its should be very straightforward.
If it checks funky, unplug the switch and simulate the stand-up condition.

Thanks for that i will give it a check..

Also in the free to fix list

Carb balance
Manifold boot vacuum leak
TPI setting/idle set

Does it give a clunk/backfire through the carbs before it dies?

nope no backfire. im thinking i found the problem ( well i hope) found a melted wire for the stand switch, fixed that and i will see how that goes...

thanks for all the input !!

mine occasionally dies when coming to a stop especially harder stops thinking it may be a carb issue

Jim

mine used to do this often, doesn't do it anymore. idle set at 1300-1400rpms, TPS set at 500ohms.

what's the verdict yeller?

Mine used to on occasion, when sitting at a stop light idling. Also would if I coasted at high speed.

New R/R and TPS (for other reasons) and it hadn't done that again until today. Arggh.

Starts right up though. It does feel like someone just shut it off.

I'm havin a smilar problem CC, I was told that the carbs need to be sync'd for that.

One of these days I'll learn how to sync a carb. I have no idea right now, never had a vehicle before with more than one carb. I've seen that it requires some vacuum tubing to do...

Is it basically equalizing the engine vacuum on both carbs? I guess with the goal of balancing the a/f mixture to each cylinder?

Syncing the carbs, and adjusting the valves are the two things that I would really like to figure out.

On the '98s you need to check the bowl vent lines to see if the run through the side rails and cross in the middle between the carbs. If so reroute the lines so they no longer go through the side rails but instead point down outside of the rails. This was a Honda bulletin and the problem was fixed on later models.

*ASSUMPTION* "bowl vent lines" would be from the carbs which are located under the air box under the tank?

Just got my 98 about 3 weeks ago and have literally put gas in it, and changed the oil.

Yes they are on the carbs. they are item #41 on this diagram

Cool, I'll look into that.

AdamK, I just got done doing a valve adjustment on mine, it's not too bad. It's a little tight getting the front valve cover off, and you have to run around trying to trade shims, but it sure beats paying a shop.

What I did was measure all the valves and check all the shim numbers, then put them back in. Then I was able to calculate what replacement shims I'd need, and if I already had them on another valve, saved me from buying those. You can only pull one cam at a time though, so you have to do everything in a certain order.
