We've been using Bostik Never-Seez NSBT-8 Regular Grade for decades. Any time ferrous, whether plated or not, screws into aluminum; studs, case screws, spark plugs etc. If a torque is spec'd for the threaded fastener or item, take lubed threads into account & reduce torque accordingly...

This locksmith data manual doesn't list the '79 model year CB750 specifically for some reason, but it might get you off dead center finding the correct blank. We had to re-key a '99 1500 Valkyrie we acquired for a song recently. The OEM keys fell victim to a contentious divorce. We found the...

Using a digital caliper. Our micrometer is... somewhere. F & R Z1 spokes are slightly differently diameters. Definitions: Shoulder - thickest part of the spoke close to the hub, before it tapers. Body - main body of the spoke between the shoulder & nipple. F shoulder - 4.05mm F body - 3.55mm...

Surprised Mama Honda didn't spec spoke torque. Found this: http://forums.sohc4.net/index.php?topic=46857.0 The OP states "...1.9-2.2 ft. lb. for the front and 1.5-1.9 ft. lb.for the rear." We would never try to set torque that low using a ft. lb. wrench; it's far too close to the bottom of...

What is the torque spec in the FSM? 60 - 65 in. lbs. and 40 - 45 in. lbs. sounds high to us but, we're used to OEM mild steel spokes on Kawasaki Z1's. Torque spec on Z1 spokes is 22 - 26 in. lbs. in the FSM. That might be different for stainless spokes; we've never used them. We lube the...

PART 5 CARBS: Remove loose exterior dirt and grime, with a quick blast of spray carb cleaner. This helps keep the ultrasonic cleaning fluid free of crud. Remove all gaskets, seals and rubber. Doing so allows maximum area of the carb to be exposed to cleaning. Remove the float bowls, floats...

PART 4 BEST PRACTICES: NEVER USE FLAMMABLE CLEANING SOLUTIONS IN AN ULTRASONIC DEVICE. Tank size is determined by part size. Generally, the tank should be one third larger than the largest expected workpiece. When a part is immersed in a 40KHz tank, there should be clearance of approximately...

PART 3 HEAT: The effect of heat on cleaning chemistry is closely related. Temperature is the single most important consideration in maximizing cavitation intensity. Changing the temperature of the cleaning fluid changes it's viscosity, the solubility of gasses dissolved within the liquid, the...

Part 2 EQUIPMENT: The ultrasonic generator converts incoming AC power from 60Hz to the design frequency of the ultrasonic transducer(s). The generator also matches the incoming voltage (110VAC) to the lower voltage required by the transducer(s). Modern transducers are usually ceramic...

Long, geeky post ahead. Some years ago we were looking for an ultrasonic tank for our Kawasaki Z1 restoration hobby. The breadth & depth of info was daunting, with some conflicting claims & info spread across the interwebs. So, we proceeded to write the article we wish we could have found...

Beam pattern on a vertical surface @ 20 ~ 25 ft. is what counts. Many H4 replacement LED's that are claimed to produce ten-eighteen-hundred-bazillion Chinese lumens are very poorly focused when installed in a headlight reflector/lens system designed for H4 incandescent filaments, which are...

In! Thx.

FYI - Saw these on a Z1 / KZ forum. Never heard of phenolic as piston material before, but research shows it's fairly common in the automotive world. https://godfferysgarage.com/#shop Good Ridin' slmjim & Z1BEBE

In & Thanks for the GAW. Not seeing much love for the '91 - 03 CB750 Nighthawks on your site. There's lots of us out here...

In. Thx!

Thanks for that response. We responded individually with our experiences. Please, if you will, advise on the above highlighted & underlined in color. We're in process of obtaining some of those items for maintenance inventory. Long-term planning. Rubber parts especially, as we've seen...

Warm-ish day yesterday. Got out on my BlueHawk for 25 mi. or so, long enough to mix Stabil into the topped-off tank. Bike ran perfectly and reminded me (yet again) why we fell in love with the 'Hawks in the first place. Will drain the carbs today for winter. The Ride was also long enough to...

Long post to follow. Thinking cap suggested. We're on multiple fences re: keeping our His n Her pair of '93 Nighthawks we bought new. Both have 70,000+ relatively trouble free, adult touring miles on them. We never wailed on them & they're always garaged. Very well maintained by us. We're...

Specifically, how is the Hondaline rack supported at the rear? We're looking to set up one of our '93 Nighthawks for day / weekend trips, with a minimum of storage. The Lovely Z1BEBE would like to have, at least, a backrest. In a perfect world, said backrest would be integrated into a top box...

In. Thx! Good Ridin' slmjim & Z1BEBE

Not sure this qualifies as a desired post, But... No love for the '91 - '03 CB750 Nighthawks?

We received a couple of good responses to a question we posted on another forum re: replacing CV diaphragms. No personal experience with either yet, just sharing for those who may be interested. https://www.carburetordiaphragms.com/ http://jbmindustries.com/Dimensions.html Good Ridin' slmjim...

Has anyone used replacement diaphragms from here? https://www.carburetordiaphragms.com/ Were they acceptable? Good Ridin' slmjim & Z1BEBE

Round or flat slide, that install directly onto OEM intake boots & correctly fit the stock airbox? Dual throttle cables a plus. Manual choke lever on the rack OK. Thanks. Good Ridin' slmjim & Z1BEBE

Bought our His n Hers CB750 Nighthawks new in '93. See our post in the 'See your Nighthawk' thread. We're also deeply involved in restoration & preservation of Kawasaki Z1's. slmjim bought his first Z1-A new in March, '74. Still has & rides it. Maintaining our small collection of Z1's, our two...

New members. Posting detailed intro in The Garage soon. Pic from three yrs. ago. His 'Hawk had ~74,000 mi. on it at the time. Her ';Hawk was showing ~71,000 mi. when this pic was taken. slmjim sez his Candy Tahitian Blue 'Hawk is more handsome. The Lovely Z1BEBE sez her Candy Metallic Red...
