BS carbs? They are supposed to eliminate whacking throttle open lean stumble by extra fuel. cliff

Bad chop, start with a new plug. Plug inspection is way down the insulator. cliff

Pix are too blurry. What copper is missing? cliff

Like I said, lazy opening. Usual measure point is .050" Threw me off. Any progress? cliff

These are very lazy cams! 36°BTDC I.O. is more like it. @.050

Intake opens WHEN? Not an adiabatic miller cycle engine. cliff

Sounds like timing chain skipped a tooth.

does this count? '74 250A

Usually the wrong compression gage with the check valve near the gage itself. This will add 8cc or so volume and resultant low...

Hi I am cliff. A rather newbie here without, but I do have an XS650 SP2 1979. Rear end that is. Spoked Borranis, 16" rim on a Kaw H1...

Concentrate on idle, you are confusing us and yourself. the 36mm cut away has zero influence on idle, kapeesh? ZERO cliff

Gasoline!

Just one port doing this? Valve guide dripping oil from rocker box. Sloppy guides do this if really bad, but guide to head casting due...

"The height that the 2.5 slides arc is cut to makes it a lot more open than the 2.0 even when the idle screw isn't screwed in all the...

Nothing to do with idle.

Forget the cable adjust Concentrate on idle, you are confusing us and yourself. cliff

More BS nonsense. Same BS as Singh Grooves on the head. What do think the current spark plugs do? cliff

Think about handlebar grounding also. cliff

Pilot circuit completely non-op You are forcing the throttle open enough for the "off-idle" cut-away/needle jet fuel to flow, just to...

Phone charger on a bike? cliff

Great patina. If you forget stuff, it does not bother you.

Underside of pistons may tell us something, I rest on my experience. Skull, you are correct on the replies. Experts here to help and...

? Is the TCI that sensitive on 12-14.5volts? Sounds like heat or fuel stave. cliff

Seal on caliper pushes piston back a couple thou away from the rotor. Or should. cliff

What iz rev limit? cliff

Methylcyclopentadienyl manganese tricarbonyl Used in the '80-'90's by all major brands. Until it was found that it clogged up cats and...

Deto-pure and simple. Classic end gas deto on hot side of chamber. Crown also weak from heat and fractured from deto. Cliff btw red...

Use non synthetic for break-in because it's cheap. Run for 10-20 minutes and dump it. cliff

Detonation-classic Top land damaged Valve cut out valley next to land

Old GM EOS. 2OZ with normal fill. Phos and Zinc for 20 minutes then dump. cliff

CA=Cut Away(how rich/lean the off idle pickup point is.

Seems like pilot circuit is zilch. Need to jack up slides to idle is just starting the pick up transition CA circuit. Screw the screw...

Great idea!

My 900 Ninja paid for, with signed registration in hand . He ripped around with a borrowed AGV. Never returned. With my 300 buck...

What was the break-in proc? cliff

Yes remarkable contrast on the plug. Glazed black is oil coking. Light brown/white crusties on ground electrode is phosphorous from oil...

Fuel wash and some oil burning. cliff

Other than slight angle. It looks good.

I'll bite. how'd ya modify? cliff

Whoaw-wow how do we measure such things? Without a u tube vid. cliff

Same here Jim. I had bought some at Roush since it was convenient. 500 bucks worth and 20 bucks a week payment. 1985 and complete crap...

Borrani's!

8/10 thou ring gaps? cliff

Keep on learning. This post is cool to see. Aero-dynamics are so cool. Various densities, velocities, mass flows and most important...

Unless forcing function is a pure sign wave, it has harmonics. cliff

As for pitot tubes.. I use them and these special valves to map velocity around the seat at various lifts. example 6.4L
