Bike WONT START!

[djg42]

I just recently had to replace the r/r and ignitor(got used parts on ebay) Bike was running good, replaced handlebars and was just about to work on some cosmetic things-but now it wont start-which f*** sucks.Just rode it a few days ago and everything seemed fine. The battery is fine, light are working and has spark. What could have happened? What should i check? Thanks!

Check the plugs for gas.

thanks for your help! Does that mean to check the spark plugs? They look clean,
could it be the r/r unit?

Install new plugs(sparkplugs), even if they look clean.
If ya been goofin around with the wiring I'd backtrack with everything you did and check it again. Pay specific attention to all the grounds.

thanks-ill try new spark plugs. The only thing i did recently was to change the handlebars. The wires did come off the kill switch and I soddered them back on. But it was runnin gfine after-and it attempts to start when I hit the start button.

It fires?......

just so i understand, you have spark, good batt, plugs clean and not wet, is the starter motor turning the engine? (thats the problem i just had/have) are you getting good compression? are you getting gas to the carbs? is the petcock working? did you swap spark plug wires?(which would give you spark on the exhaust instead of compression stroke) well good luck in getting her running again.

Thanks!-all i have done so far is to check for spark and check the battery. Im not really how to do much else, but in the past have got by with advice here and the manual. Where should I start?

If it ran fine before what did you do to make it not run?

 

[djg42]

not sure. I put different handlebars on it and took it for a ride a few days ago. Tried to start it up today and iti dont know what happened

I have been having the same problem with my 700. I have a spark, plugs are wet, fresh battery, new petcock, carbs re-built. Starter turns over and it sounds like it going to fire than nothing??? Starter turns and turns??

****ty--what does it mean -plugs are wet-how do i check mine?

 

[djg42]

thanks

Kinda hard to read the asterisks. Please try to use words that won't get bleeped.

How do you check the plugs?
Try cranking the engine like you have been.
Remove a spark plug, look at the porcelain.
If it's wet, you have wet plugs. :-\\\

[djg42]

and I want them to be wet-right?

 

[Steve]

"Wet" tells you that they are getting gas. Maybe not the right amount of gas, but at least there is gas getting to/through the carb.

Ideally, the plugs will remain dry because they lit the gas mixture and burned it, but if the cylinder does not fire, a wet plug will tell you if it's getting gas or not.

[djg42]

OH, i understand(i was really just testing YOU)
Im going to check

 

[jwhelan65]

So if you have a spark and plugs are wet , bike turns over...rumbles at first like its going to fire...than periods of nothing.

Also, how old are the plugs? I've had plugs "die" from getting too much gas or whatever lil gremlin sits in the cylinder and chews them up. They can often look fine with good blue spark and all, but when you install them, they don't really work well enough to burn the fuel. Try getting some new plugs. It worked for mine. Also, check to see if you might have a blown fuse.. Simple the problem, the simpler it is to overlook...

I just remembered adjusted the throttle tube/cable before i tried to start it. If the throttle tube or cable isnt on right could that prevent it from starting? Thanks
