Tech / Re: old problem ove rlast 20 y...
Last post by ducpainter - Today at 03:50:45 PMI'm thinking back to the mid 80's when cars sucked. They had relatively primitive electronic ignitions, carburetors, and were basically pieces of shit.
The biggest problem Ford had during that period was valve guides, and when they were bad...every single one...they idled like shit.
Just sayin'

Last post by koko64 - Today at 03:34:15 PMQuote from: Howie on Today at 07:46:47 AMCheck the clearance and resistance on the vertical pick up .6-.8mm, 95-105ohms. Coils too, primary 3.8-5.2 ohms, secondary15.6 -23.4 ohms
Maybe rear pick up gap is a bees dick wider. It has been suggested that inductive pick ups get a weaker signal at low rpm.
Fastbikesgear in NZ recommend a closer than oem clearance for the pick up coils to improve idle and low rpm running. They suggest 0.4 - 0.5mm due to the weaker signal at low rpm, or as close as possible plus a bees dick for thermal expansion.

Last post by koko64 - Today at 03:26:34 PMAnother thing. Carb synch is sometimes more of a compromise on some bikes than others. Some bikes, once carb synch is set, have an even synch all the way from idle to higher revs, while others require you to decide where the less than ideal synch should be. It may just be a 500 rpm zone, but If that zone can't be easily tuned out with jetting, cam or ignition changes, then you have to decide where to put it.

Last post by koko64 - Today at 03:20:25 PMI reckon I'll re-read the whole thread again to get my head around it. It certainly seems like you have gone through a long diagnostic list better than most.
A thought, tick over quality can sometimes be related to closing shim clearances or valve/valve seat condition.
If a bike has been rescued from a salvage yard and been sitting for years, a valve seat/valve face may be pitted due to the fall of the cams exposing it when the bike was turned off.
Seen and heard of rear exhaust valve seats (iirc) being weathered from bikes that sat. A couple of guys alerted me to that years ago when I bought a salvage bike from Japan.

Ticking off a few to-do's today. Supposed to be in the Mtns w/the girl gang (who I miss and need) but you know... dog capers interfere. It's what I signed up for. So... will get a bike ride in hopefully before the sun sets.
I signed the dog up for a feeding tube during her liver and GI biopsy that's scheduled for Tuesday. That will be fun but "they" say if all goes good, will improve her (my) QoL long term (tube will be weeks, a few months at most).I've done all I could to get answers to questions, talked with a number of vets not on her case so decided that's what we're doing.

FFS indeed

Last post by jerryz - Today at 12:20:26 PMKOKO the pilot jet is .40 ,, same in my M750 which is perfect the manuals usually say 37.5 for 750ss
Also usually the Horizontal cylinder needs 3.5 turns on Airscrews like my M750 BUT the Vert cylinder has always needed 4- 4.25 turns which is again an anomaly ,
But as i have said once off tickover the 750ss pulls evenly and smooth like a rocket up to over 125mph

i have done that , i also took the coils and pickups off the Monster 750 and tried them and it made no difference to the 750ss ,, when i put the 750ss coils and pickups and HT leads etc on the M750 it runs absolutely sweetly at tickover , even and crisp...
Thats why i am sure its not electrical ..mind you when i swop the carbs to the M750 they also seem to run better at tickover
Over last 5 years I have looked at this Anomaly several times ,, I have even changed the long intakes from M750 to 750ss and all the rubber carb mounts and seal,seven the cold compression is OK on both cylinders at 146psi front and 145 psi rear .
it make just be because the 750ss is a very early 1991 bike number 693 and the M750 is a year 2000???
im going to check the valve clearances on rear cylinder again, before i put the carbs back on but I did them only 18 months ago and the bike has only done 700 miles in that time , as i have so many other rides ...
