thanks! That's the plan

I hope the 10K comes back in spades.

Wow! I can't believe it's been so long since I posted here.

Not a whole lot has changed. I did swap out a 12-in chuck lathe for a 15-in chuck lathe with a much longer bed length and a ton more horsepower. I love that thing.

The biggest change is that as of yesterday we are officially AS9100 certified.

That means we now have an acceptable quality system in place that lets us be eligible to machine parts for the aerospace industry.

I'm excited to see what doors this opens or to find out if I lit $10,000 on fire.  I've invested more and gotten less before so here's hoping

I`m wondrin how a snapped belt could damage a plug like here?
Usually only causes piston and valve to meet or?

The belt didn't snap. It might have jumped teeth.

The next step is to pull the cylinder head to see what's happening inside.

Regarding the spark plugs: I went to AutoZone, and they recommended the NGK DCPR8E based on my bike's year, make, and model. Previously, I was running Champion RA6HC. Do you think the cross-reference could be the issue? I suspect a piece of the broken plug may have dropped into the cylinder and caused the obstruction/damage.

i have owned my 750ss  along time , but the carbs have always been a little of beat and rear cylinder is hesitant at idle , My other ducatis dont do that ..


The  Mikuni BDST 38s run great above 2k rpm all the way to over 125mph++ but are lumpy a at tickover and rear cylinder is hesitant at tickover until 1500 rpm then its fine all the way to 8k rpm . and always have been for last 20 years but its annoying me , so i have the carbs apart again , they were ultrasonic cleaned twice last year and i rebuilt them with new parts , gaskets ,orings , new emulsion tubes ,new diaphragms , new bypass rubbers ,, etc etc but it made no difference ,, only parts i did not change 5C19 was needles,,, and slow running jets , float height 14mm ,, this is bugging me for many years LOL
 
140 main jets,
70 pilot jet 
1.4 slow jet   
5C19 needles new emulsion tubes
13mm Float height
New airscrews  and Orings etc etc

NO AIR leaks , Engine Valves are perfect etc etc
electrics are also all new plugs , Ht leads, coils pickups etc etc ,,

bike runs lovely but once off idle ,,, I want it perfect like my Monster 750 only difference is M750 has stage 2 Dyno jet ....

+1.
