evil Posted November 19, 2003 Report Share Posted November 19, 2003 would the cdi or coil getting wet cause it to feel like the throttle is stuck ? Quote Link to comment Share on other sites More sharing options...

BenBB Posted November 19, 2003 Report Share Posted November 19, 2003 Water KILLS CDI's, luckily they are well sealed but if water/condensation ever gets inside that's what kills 'em. Not sure about the coil, although they appear to be pretty well insulated, but in either case I would think water would cause a short and kill the ignition instead of making the throttle stick. I still think it's (water making the throttle stick open) something to do with the carbs, not sure exactly what the f*ck it is though...

Yamahammer Posted November 20, 2003 Report Share Posted November 20, 2003 Is it possible for moisture to cause the advance to stick so instead of it being at 10 deg it is at 20 or what ever it is.. This would cause an increase in rpms like a sticking throttle?? How does the advance work on these bikes is it at the cdi or on the fly wheel mechanical or electronic.. I am trying something on the carbs will post it in the carbs sticking topic Quote Link to comment Share on other sites More sharing options...

BenBB Posted November 20, 2003 Report Share Posted November 20, 2003 Yamahammer-it's all electronic, inside the CDI. Evil-I'd think it would be worse at upper RPM's but it would still idle (depending on how much air gets in I guess). On a side note about the carb sticking thing, I noticed on my RZ carbs that have the standard Mikuni idle screws (you know, a thumbscrew with a spring instead of a locknut), that there's an o-ring on the screw. At least in my case with the TORS removed that COULD be where water is getting in, but if I remember right some people had their throttle stick without the idle screw kit installed...

evil Posted November 21, 2003 Author Report Share Posted November 21, 2003 weird thing was is there was no water involved at all Quote Link to comment Share on other sites More sharing options...

Lean is mean. Think of a lean pilot. It should still start, it will run real "zingy", meaning it free revs cleanly, and kind of zingy, I don't know how else to explain it. But you would have to give it alot of fuel to start off. Does the bike calm down if you pop the choke on a tad? Spraying some carb cleaner around the carbs and base gaskets while it's running will find a leak. Quote Link to comment Share on other sites More sharing options...
