1100 pulse generator-cleaning

Postby tlcdmc » Wed Nov 03, 2010 2:27 pm



removed tank to clean-thought i would check pulse generator while somewhat accessible-seams to have some kind of orange film on generator coils on inside, on cover and around outside of housing. what can i use to clean this area without harming anything. thanks

The area is sealed from the block with a oil seal,so i don't know what it may be(rust powder?)but beware,there is a moving mechanism in there.Don't just spray some stuff on it.Look at the service manual under ignition system.I'd disassemble it,clean it(i always start with a little soap and water before using carb cleaner)dry it ,lube it,check the vacuum advance mechanism and hose,re-assemble,check and run.

soap and water sounds good-trying to just clean it on engine-didnt have very good luck on parts bike trying to remove swing arm-do not even want to attempt on this one- ohm readings ok on generator so i just want to clean. gasket on cover was not sealed but i think i will seal it when i put it back on. thanks

Check the vacuum advance mechanism for operation.mine was rusted solid.use a hose,suck a vacuum and verify the pickup coils move.

vacuum advance working and mechanical advance working- decided to use pb blaster-sprayed small amount into plastic paint can lid-took q-tips and wiped down whole area-didnt see on label for pb blaster about harming parts- i know reluctor had film on it, but coil pickups were covered, probably causing me some trouble- had similar problem on my 1977 ford 350-w/460 engine in my rv. reluctor was rusty but coils were fine-they were quite inexpensive, so i replaced it all. after i get her back running, i'll keep up post for results. still have to clean gas tank and go back in to reclean carbs. yippee.

Rust and metalic Crud on coil pickup or the trigger can result in a distorted output to the cdi.this may cause small variations in the final spark timing and duration.

The universal solvent I use on just about everything is brake cleaner. It evaporates extremely quickly, and doesn't damage plastic or rubber. It dissolves grease and gunk instantly, and it all just flows out the bottom, leaving no residue behind.

have been suspecting for some time that misfiring problems might not be carbs-sometimes bike runs like new, then misfiring so bad, it was hard to get going. i know that film on generator has to have impact on performance. will try spraying with brake cleaner to finish cleaning area around and behind coils that i cannot reach otherwise.thanks

Hey virgil, I'm working on getting to the advance mechanism and learned that the passage was blocked up[metal nipple for hose] I got through with a small wire by poking at it, I guess I need to remove the swingarm to get it the pick up coils right or just the tank or both.?.The manual says just the swingarm but I want to ask someone who's done this because I haven't.. Any advise sir would be appreciated..Thank You Or anyone else Please..

Did you spray it and what happened? I'm going to get in at mine and and take a look, probably because I'm so nosey and curious, I really need to see if the pickup coils are moving or not as Virilmobile suggested...I guess if they don't move I need to remove them to clean proper, Is that right???

decided to clean with just the pb blaster and cotton swabs. i have extra motor, i took cover off of it yesterday, and it is covered with same rusty orange film. recleaned carbs, had trouble with accellerator pump blocked at check valves, cleaned fuel tank-fired bike up yesterday, still have problem with misfiring,or backfiring at low idle. the pickup coils advanced like they should, the vacuum advance control arm also was working -although i dont have capacity to check vacuum. i do not believe film on coils affected bike performance-i sealed gasket when i put it back together anyway. going back to work now checking ignition. thanks

It sure sounds like your slow jets are clogged to me...Have you got to them yet..??? They are hidden in one of those posts or towers...way down in there..and they are pressed in on the 81's..Not supposed to come out but there are way's..

used the wire brush suggestion to take one strand and work through holes.- having misfire on 2-4 cylinders-can hear it at exhaust-bike revs and runs fairly well on road, just has miss or backfire when engaging throttle. thanks

How did you end up getting the slow jets out of the towers?

didnt-used small wire and needle nose pliars to work wire into hole in tower-dont know how effective that was, but it was suggestion on another web site-all sources i have read, say jet is not removable on this model. used carb rebuild info from this web site to check carb passages for clearance-(little beaver-i see you are close to my location-kc,k-im in kcmo-thanks
