Notes taken by Don Broxson from Chris Greenbacker's first tech session:

Hylomar AF for rocker covers, NOT cases. Does not harden

Three bond 1184 for engine cases. Very liquid so store vertically in coffee cans

X-profile seals for kick start and shifter shafts

.010 for clearance

Tach drives machined for factory seals

Engine oil
Lucas 20-50 breaking oil
Valvoline VR1 20-50 afterwards
Or 15w-40 Rotella T4 for diesels

Anti-wet sump
Vacuum or ignition activated
Longer than 3 months, pull the feed hose and fill feed pipe (to re-prime

Drain sump, Flush tank at beginning of season 
Make sure there is oil between anti-sump valve and pump
Make sure oil is returning
Synthetic more prone to leaks
Change oil at 2k miles
At 50k break crank down and clean passages 


Oil tank repair
Replace top mount with heavier gauge steel
Braze

Oil lines
Derale auto transmission cooler hose 11/32 ID
Closer fit than 3/8 & oil resistant 

Deburring wheels are useful

For scratches use med, fine, AAA, then white rouge

You can buy valve stems 2mm shorter

850s, quality of flame rings has dropped. Now using copper-cote

Threaded exhaust port:

750 has 50 deg thread pitch, 60 degree for 850

You can get 850 with extra threads for 750 pipes

Recoil offers help oil exhaust thread repair kit

Requires drill press or vert mill


Piston rings
3 piece oil control rings hard to install

JCC pistons are cheaper than Hepolite
No 850 break in issues, but on 750s use dingle ball hone to ensure seating

Reed valve crankcase breather from Yamaha 650
Put low on 850; on 750 behind oil filter with zip tie

NYC Norton has sump plug breather

Removing seized pistons
Drill relief holes in piston, add kroil
Rings never touch bottom inches in bore so it'll be tighter than upper part; don’t drive pistons down

Some 750s can take 1,500 miles.  850s can fail to seal.

Layshaft engagement dogs can skip on gears.  
Ratcheting can also be at fault

Replace layshaft bearing with roller bearing

$150 - RK Takasago 530UWR UW-Ring press-on link.  Motion pro makes master link press tool

Shifting problems are from clutch.  Flame hardened clutch hub center.  Or use Barnett alloy plates so plates wear not center.

Barnett plates are 3.6, Frodo plates are thinner

750s are 2mm .  Adding a thicker 3mm plate makes clutch pull easier

Primary should move 1/2 inch under pressure.

At least 8 thousandths clearance, 0.010 for belt drive.

Use mosfet voltage regulator to get more power, but not cheap. 

McMaster Carr has narrow face washers but only sell in volume.  Get dimensions from MMC and look on bolts us.


Fork seals- “Progressive Seals”.  They are pressure balanced seals from British cycle supply
