total failure
hi all, would like to pick your brains if i may, this story may take some time so bare with me please!!!. last august i bought my first cbr 1000f an 1989 model which i buoght sold as seen with no sevice history but everything seemed to be running fine with only 30,000 on the clock, frame and bodywork, tyres all in good nick so everything was fine for first few months until i decided to use my little 125 for the winter and put the 1000 away. About 2 or 3 weeks after on a nice sunny day i decided to take the big one out for a run, but try as i may could not get it started even after charging the battery. It seemed like it wanted to start but got alot of backfiring.
So it was at this point i decided to get the problem sorted by a local backstreet machanic and also for him to do a full service???? (god what a mug i was). He said it was a carb problem and that he had sorted it!!!, changed the plugs and oil, and a new battery was fitted as the old one was knackered???. i took him at his word. things seemed to be fine for a day or two until it wouldnt start again, i soon relised that the only work that had been done was the oil change, (bloody bastard) i would have ripped him a new ****!!! but he has got some really ugly mates and a bigger baseball bat than me!!! so i put it down to experince. So anyway ive now got a new battery, new plugs, and a battery optimiser and everything seems to fine??? it starts first time, (sometimes with a little choke) but a lot better than it ever was, so took it out the other day for a good run and everything was fine, about 60 mile round trip, so you can imagine i was very happy?? until the following day when i went to work, (about 3 miles away) it suddenly died on me at a very low speed this has now happened twice, as you can imagine this would be a little scary in the fast lane of a motorway. i have since checked the plugs and found 2 & 3 to be fine but 1 & 4 to be sooty??? i also noticed when i turn of the engine there is smoke still coming from the righthand exhaust??? can anyone help me as i don't want to give up on the old girl

We may as well do this step by step mate...
Why 1+4 are sooty ?? / The only way they are connected is by the coil ..
Because 1 and 4 are off the same coil Mark , I would check that first...
Pull those plugs and compare the spark between 2and 3 and 1and 4 ...
let us know if they are noticeably different mate..
The smoke is prolly only unburnt fuel ...hopefully ...
I have to get some sleep now mate.... Shadow or the other guys will be along soon I am sure :-)
I will catch up in the morning ...
chin up..shes too good to give up on :-)

the back fire could be the unburnt fuel igniting in the pipe from heat...I would agree...check the 1/4 coil and the wire running to it, and the plug where it connects to the harness...make sure its got a good connection and isnt corroded...also check the HT wires, but I think it would be in the coil or before.......

Coil may well be the problem, but a thought comes to mind -
Maybe 1 he just cleaned up the plugs, and didn't change them, or
2 he's put in plugs which are the wrong type.
3 He regapped the plugs to the wrong setting - should be 0.8mm for info.
DPR9EA9 are correct ones, for info.
3 If the bike just died, maybe the reg/rec is faulty - if the battery isn't getting enough charge, these bikes are inclined to stall at slow speeds, because the battery will only begin charging above 3000 RPM with a standard reg/rec. (I have an aftermarket one which gives me 13.5 V at 1500 RPM - big improvement)
Are you SURE it was a new battery, not just one tarted up to look new, with fresh acid, which may last a day or two ? You must have some recourse on that at least.............
My course of action would be
1 Check the charge in the battery - should be 12.6V or more with the engine off, and 13.5V or more with it running above 3000 RPM. If that all checks out, your reg/rec is fine, but the battery may still be faulty.
2 Have the battery "load tested" at your local battery shop - it's quick and will tell you if all is well there.
3 Pull the plugs, check for spark, type and replace if you think they're old.
4 Run a test on the coil leads to check for breakdown. cracks etc.
There are probably other areas to check, but those come to mind......
Oh, and recruit some big, nasty friends,,,,,,,,

CBR and Nasty friends
Check the voltage going to your coils. Both coils should have the same voltage as your battery. Your 1/4 coil may have a problem with lack of supply voltage. If they are the same voltage as the battery, then there is really only two problems that might be the cause. The coil/lead wire/plug or your carbs. Number 1 and 4 carbs just might have all the planets lined up in the universe causing them to have a low speed jet plugged problem together (wouldn't that be a cute thing for them to do together!). I would start at the coils and then move to the carbs.
Now for those nasty friends of the moron who claims to be a mechanic. Out here in Nevada, we strap 44 mag pistols to our side. Perfectly legal and in fact, my neighbor, a Reno Cop, told me to strap one on my side to protect my dog from the neighborhood pitbull (when I take her for a walk). Now I have no more pitbull attacks because we have a lack of pitbulls!!! So, here is my recommendation. Why bring a baseball bat to a gun fight?..... Let the other sucker bring the bat....

It's all this good clean high desert air. Clears the mind. Of course, having the prevailing "Wild West" laws here in Nevada makes for a more even playing field. God created man and Smith and Wesson made them even. Now if man chooses to use a bat to a gun fight, then God must have created that guy with a little brain!
Oh, oh, the weather says mid 60s and no wind! Looks like I'm going riding. Looks like I am going to stop at the Bucket of Blood Saloon, take a leak on a few Harleys out front, walk inside and tell the leather boys that it looks like their radiator on their bike leaks. Most new Harley riders (wannabee bikers) will take their bike to the shop to have their air cooled bike's radiator fixed.
Oh, this is going to be fun.....
Yes, Shadow, of course I will riding with my 44 strapped to my side. Modern day cowboys do still exist out here in Nevada, only they ride CBRs... Horses sh*t too much to ride...

Are you related to Judge Roy Bean - the law West of the Pecos.....................?
He had a similar view.
I prefer the Ruger Super Blackhawk, myself, pref with Black Talons or Hydroshocks....as the Irish say
"to be sure, to be sure"
Have a beer at the Bucket for us......
