Hi,
I know this is mostly for goldwings but I have a problem not able to solve.
I have a 1986 450 cc Honda nighthawk and I am Stumped Big time!
I do not have any fire to the plugs, I have replaced the COIL- the CDI UNIT and wiring also new plugs, I have 150 LBS compression on each CYlander and I also can not get fuel into the combustion chamber. I rebuilt the carbs and fuel is getting there but spark plugs are dry! and even if I got fuel there NO SPARK, I have put in 2 different coils and 3 different CDI units and nothing alsochecked the Kill switch. I bought this so I could just tool around the neighborhood and leave my GL1100 parked. It was not running when I bought it and they said they had been on a 3 hour trip when it quit and would not start up, I thought itwould be something minor but I guess I was wrong.......
Please any one have an IDEA??????
This is a great forum for Goldwings but I do notknow of any for this type of bike.
Thanks,
Bailbob

Yes I have a manuel and yes I have gas flowing, that's whats weird. Everything I know about trouble shooting I have done and yet I must be brain warped as this escapes me. An engine needs air, gas and spark along with compression to fire, but why am I not getting gas into the combustion chamber and spark???? I love trying to solve these problems but this is beyond me! NO GAS NO SPARK both different problems but still the same. I think I will sleep on it tonight and try again tomorrow.......thanks everyone!

Good morning all,
Well I went to check the pulse generator switch and then I found that Honda does not provide specifications for all models mine being included. I have the Clymer service repair maintenance book covering 1978 thru 1987. I have a place that sells used parts for motorcycles and I think I will see if he has a stator and how much it will cost. The CDI unit was $140.00 used but it does not help so I do not know how much a stator will be and they are closed until Tuesday. Thats the plan as of now......Thanks everyone for all your help.

Well heres a stupid question.....I just noticed that there is oil leaking out of the stator cover and down the side stand (took it off center stand to move it) and left it over night on the side stand.... Question is should there be oil in the stator? its not a lot of oil but enough to leave a smudge on the garage floor. I am going to check to see if the guy that sells used bike parts has a used stator tomorrow as they were not open today....any ideas on the oil leak???

On closer examination I think you are right as there is silicone around the stator cover as though someone did not have the proper gasket or was trying to stop the oil leak. I plan on taking a closer look tomorrow and will keep all posted as to what I find.

UPDATE:
I had to wait to get a tool to remove the bell housing off stator, replaced stator, replaced CDI unit, replaced coil, new plugs, battery full charged still no spark at plugs and on top of that no gas in combustion chamber (spark plus are dry) no oil on old stator as I thought might be the problem why no spark. I have raked my brain trying to figure this out even if no spark why NO GAS??? Carbs have gas and cleaned and serviced them before having no spark as well as no gas before servicing them. Compression is at 150 to 180 LBS. the rubber intake manifolds have some damage (Brittle) but still seem to fit snug. I have tried spraying starting fluid into the air cleaner to no avail as no spark. Give me a GOLDWING ANY DAY!! anyone out there with any ideas? As I said before I know this is for GOLDWINGS but I have received a lot of information that could apply to a lot of different bikes..... THANKS EVERYONE

Thanks, According to the CLYMER HONDA 400-450CC twins 1978-1987 my 1986 450 does not have pulse units but it must have something but I do not know what to look for.

I just checked the positive side of coil and (nothing) thats checking with the ignition switch on but not trying to start. Also I can not check the vacuum on the carbs as the air box will have to be removed. I will do that tomorrow.
Can I run a wire from the positive side of the battery to the coil as if I was hot wiring it with out damage?

Thanks again, I will try that in the morning as we are having a bit of a storm right now. if I have spark to the plugs by doing this what in your opinion is my trouble?

Ok, I ran a wire from the positive post on the battery to what I thought was the positive side of the coil (the only side that has 2 wires going to it) and nothing but sparks (as in dead short) on both wires. NOW WHAT?? I am glad I do not do this for a living I would starve!

also I took the kill switch apart but how do I get around it?

Ok thanks again, I will do that in the AM

Well I did connect the 2 wires together but still nothing, I went back to the coil and if I put my voltage checker to the positive side of the battery and the negitive to the coil I get a reading of 12.6 to 13 volts but if I switch it I get nothing. I also had to take the gas tank off again and when I did I found the line had a brake in the hose but because the bike had never started it must have held together so as not to leak were I could see it ???????
I thought I had enough smarts to figure this out but the deeper I get the more confused I get NO SPARK----NO GAS I will replace the gas line and see if that fixes the gas problem but with out spark it is no good....Oh well my problem is very small compared to some! Thanks and if anyone has an idea let me know, I'll be in the garage looking for my sledge hammer! Ha

Thanks, I did not check it as the lights all still come on and the bike cranks.

UPDATE: I now have spark to the plugs had to disconnect the two wires going to the kill switch and then I had spark, No gas yet but I will look at this in the morning. I will probably have to pull the carbs again.

Thanks for the tip. Will do. The mini boots are brittle and I intend to pull the carbs again in the morning and I will try the silicone until I can replace them.
