Stock everything engine wise
Was running fine a few months ago before I decided to do some maintenance to replace the valve seals.
Replaced valve seals to stop oil leaking into cylinders then had her running again but got the wrong valve cover gasket so I didn't put it back together until today.
Checked and replaced valve clearances, all are set on the low end of around .038 mm. Spec says .03 to .08.
Also changed points cover gasket(for lack of better term right now, i know it doesnt have points).
While it was down and apart I ordered new intake orings and petcock.
Cleaned the intake mounting surfaces and put on the new orings.
Finished putting it back together and the darn thing idles high and the tach reacts very sluggishly.
took the tach cable off the valve cover and spinning it by hand creates pulses on the tach. Taking the cable off the tach end and the cable spins rapidly. Is my tach screwed somehow? I did take it off when changing handlebars.
Second and worst issue.
First starting it, the idle jumped high and realized the idle screw was in too far. A second start, the throttle cable was too tight from changing throttle cables. Fixed.
Still, high idle. For some time, without choke, it idles to 4 or 5k. With choke, it idles around 1500. With the choke on, the throttle response was great, engine speed returned to normal quickly--thinking lean. Checked spark plugs and theyre black with dry soot--thinking rich.
Messed with the mixture screws on top of the carbs, turned them all out 2.5 turns. Now the engine idles high on choke,won't idle at all without. Now I'm thinking it's super lean but I can't find a mixture screw setting to get it in between.
I've checked for intake leaks by putting gas in a spray bottle an spraying around the carbs on both sides. No changes.
Cleaned the carbs 2 times. First was just spraying, second was full disassembly and overnight dip.
My next thought is the contacts under the cover got dirty with grinding dust since I was working with metal in the same 3 car garage. The magnets had some iron filings stuck and I cleaned as much of it off as I could. I don't have a timing light, nor have I ever checked timing before. I'll have to review the manual for this if it could be a cause.
Any ideas?
