Re: 75 860GT ignition question

At the risk of stating the obvious, the TDC you speak of is compression stroke. Not exhaust stroke. Hey it's been done before.......

Re: 75 860GT ignition question

Watching with great interest here as I have stumbled across the same system at a price that I just could'nt turn down. It's laying in the glory box as I type. I'm yet to install it due to another project.

Re: 75 860GT ignition question

I certainly admire your tenacity Blaine.hale. Most would have given it away by now. Kicking back always spells ignition timing issues to me. I have never dealt with a petrol motor with suss cam timing so not sure how they'd react. Never seen a carb cause kick back either but maybe if it's sucking ai...

Re: 75 860GT ignition question

I've had my GTS for 32 years. Second road bike I ever owned. She's only got 78k on the clock and the vast majority done in the early days. More civilzed machinery is my day to day choice these days and the old girl only comes out to play on sunny Sunday's or if I'm feeling a bit nostalgic. During ou...

Re: 75 860GT ignition question

Could the insulation on the wiring to the stator be rotten and maybe by moving the wires you had a moment when they were'nt contacting each other?? I had this issue on a Bosch ignition. Basically with age,oil and heat the insulation goes rotten on the wiring and contact each other. Bad news is the o...

Re: Engine noise, vertical cylinder

Noises can have a habit of telegraphing. That is the noise can be elsewhere and the noise kind of transmits. You don't mention the bike in question. Reason I mention all this is I saw a similar thing on a friends GTS860 and it was the sprag/chain on his starter motor. Long story short, I had a quick...

Re: 75 860GT ignition question

Call me simplistic...........but it sparked and would'nt run. You swapped transducer leads..........runs like a clock..........you mess with transducer leads and it sparks and won't run again....................surely this has got to be mixed transducer wiring again..........

I make them out of bits you can buy at electronics stores. Can list the bits I use if your keen. One I made has worked for years.

Re: 75 860GT ignition question

If your getting 130 psi compression while kicking it over I would doubt that's what stopping it from starting. You should have some sign of life. If your plugs appear to have some fuel on them then I would guess it's maybe a spark issue. Even if your ignition timing were out you should get a pop or ...

Re: 75 860GT ignition question

Or sticking valve. Squirt of oil into a cylinder would pinpoint sticking rings. Oil helps seal the gap. I would expect that if you were experiencing lowish compression, that is low compression not no compression you would still get some sign of life. As in an occasional pop/fart/gurgle. Are your plu...

Re: 75 860GT ignition question

The cam timing marks are hunting teeth. That is once they are lined up they won`t realign until the engine has been rotated X amount of revolutions. They won`t realign with each cycle of the engine. If you have messed with cam timing marks it might be worth your while to consult the manual and go ba...

Re: 1980 900 SS Coughing when cold

Maybe have a look around inlet manifold seals. Always pays to sniff around the simple things first. These are well documented to perish and allow air to take a short cut. If no joy there perhaps check the the choke cables (if you have the same set up as my 82 model) are allowing your choke mechanism...

Re: MHR reg rec meltdown

FWIW I have seen intermittent electrical faults occur where the loom passes the steering head. Issues I have seen were on older bikes and the insulation wears through from years of rubbing around the steering head and electrical shorting occurs when the bars are in the right place and it`s bumpy. Ho...

Re: Ducati diesel

Sorry I can`t get any more info on this. I found it on gumtree for sale while trawling for bevel bits. Caught my eye as this is the first I knew they had a go at diesels.
