It was this photo on E-bay…

…that made me want this bike…a lot. It was purple, it was powerful and it had enjoyed a “frame up reconditioning” and therefore must be ready to ride. After a brief discussion with some friends over the high price and whether it was really worth it, the responses ranged from was “it’s worth it if you want it” to “not $16,000 of MY money…(for that was the Buy It Now price)…..I put in my highest bid and then turned back around and watched the scene as Robert Plant, John McEnroe and Sheryl Crow carried on a conversation in an RV parked outside the backstage door of the Beacon Theater, New York City in the spring of 2019. If only they had known what I had just done…..I don’t think they would be even mildly interested, but all of that, is another story.

As the night carried on, I was kind of hoping the bike wouldn’t come through…..

Nevertheless I won it…

…and I was very excited. I must have read and re-read the description at least 100 times. (Pictured right) A day or two later I spoke to the seller and he sounded very much like a connoisseur of the Kawasaki triples and outlined how he liked to jet them just so to let them unleash their riotous power and run well.

I was stoked and figured that I was buying from a tuning guru and all would be well….

I was in for a bit of a shock.

Tankgate…

The paintwork was beautiful and the color is truly what sold me on the bike….but inside problems lurked….

Next: The Engine.

I always knew my first encounter with the iconic triple two stroke would be something to remember but thought it might be a little more exhilarating. On the first ride the engine sounded like a bag of hammers, it pinged, it surged, it ran on two, then the third would kick in right after it threw a fuel/oil mixture all over the pipes and rear tire. Yes, the Widowmaker was trying to kill me. I was in no mood for point by point diagnosis. These motors are simple, so I decided rather than troubleshoot I would strip it down, examine each component carefully and replace anything suspicious. This was a good plan because it would allow me to remove the one thing I couldn’t stand about the look of the bike: the paint job on the engine!

A painted motor looks great….in a picture….or from 12 feet away….but in my opinion has no place on a restoration unless that’s how the factory did it. Having said that, only yesterday, I read an interview with an ex-Grand Prix mechanic Nigel Everett…

A painted motor looks great….in a picture….or from 12 feet away….but in my opinion has no place on a restoration unless that’s how the factory did it. Having said that, only yesterday, I read an interview with an ex-Grand Prix mechanic Nigel Everett who’s building a KR750 replica and said about paint and race bikes….“Kawasaki were a nightmare, they used to build the engine and spray it black-covering all the nuts and bolts and everything.” However this isn’t a race bike.

 

The Wheels…

Don’t assume they’ll be fine. I did until I was working on the rear end installing rear brake shoes…and one day playfully spun the rear wheel to find it not to be so true…

 
 

Not disastrous by any means, nor unfixable, but not the condition you want to find a wheel on a high powered vintage motorcycle. So I took them to Ryan at Motoresurrection.

He’s been building wheels for years….

The Brakes….

I’ve never read reports of fantastic brake performance from the OEM front calipers, but with no intention to change the look of the bike, replacing existing components with modern pieces was out of the question so I decided to add another front disc. The seller offered to do that for $2,000. I passed on that and elected to take it on myself- but note this is in no way a lesson on how to do it! If you choose to copy what I have done- you do so at your own risk…brakes will save your life…or ruin it if they don’t work…

Update as from Apr 2022

I decided to rip off all the calipers on the 3 H2’s and send them to the powder coater to get them covered once and for all. No paint I had used in the past, no matter how well I prepped them, managed to stick to the calipers. It didn’t help that I am of course the worst painter so I decided to let a third party take care of it. Superior Powdercoat and Sandblasters of Nashville.

Now you see them….

 
 

…now you don’t.

Swingarm….

It’s no secret that the handling of these bikes is not the best, so I’ve sought ways to improve it without altering the outline of the bike. Worn swingarm bearings can make it feel like it has a hinge in the middle The OEM’s are plain steel bearings. You can take one step up to brass or go all the way with a needle bearing kit from Ralf Gille in Germany. I managed to get a couple in 2019 before COVID hit, after which he was prohibited to ship anything to the USA. There’s no longer any reference to the kits on his website. I may have got the last ones…

Steering head bearings…..

— when I removed the front wheel to attend to the discs I moved the steering from left to right…it was notchy AF. After doing the swing arm bearings, installing a taper head bearing kit from All Balls was the obvious next stage.

Stator Rewind…….

My overall goal was to eliminate problems by assessing each component vital to a fully functioning motor and then do whatever it takes to get the component up to scratch, or replace it. In terms of the electronics, with new coils being cheap and readily available it made sense to invest in new coils and plugs and get the stator tested.

The only place I could find that dealt with these stators was Rex’s Speed Shop in the UK. I sent them the stator and they came back with this: “The stator has failed both the low and high speed tests. The pick ups are under specification but they are all reading about the same. I have seen pick ups work at this reading but I can’t guarantee they will work. I recommend a full overhaul with new CDI and lighting coils and new loom. “ Turn around was almost exactly two months…. and have had no issues with the pick ups.

Meters…..

It took me awhile to get to these. Despite new cables both the speedo and rev counter had very wavy needles. I sent them to Don Fulsang in FLA for a full refurb. He determined that the rev counter was in fact from an H1….the difference being the redline on the H2 rev counter should start at 7500 rpm rather than 9500 rpm…new H2 faceplate is the only alteration to bring it up to spec.

In Summary…

It took me a while, and yes, I perhaps did a lot more then needed (e.g. install of swingarm needle bearings, a stator rewind, overkill on Tankgate ) but the bike I have is now solid and is what I dreamt it would be.

Note that, as with my H2 other builds, I could not have done any of it without the endless true first hand knowledge from the great gentlemen on the Kawasaki Triple Owners Club (KTOG) all of whom are exceedingly gracious and generous with their time and have had the patience to read my questions, digest and respond with good advice whenever I needed it. Thank you all.

Back to the bike: There’s no question that it had a lot of good parts thrown at it before it got to me. The Lakeland CDI, new shocks, good seat, reconditioned Charlie Smith crank to name but a few but what was disappointing was quality of workmanship on the machine which lead to the incorrectly connected oil lines, the notchy steering bearings, sloppy gear change (the bolt securing the shifter was screwed in from the threaded end first so was unable to grip the shifter splines), untrue (and internally rusty) wheels, unconnected neutral light, the filthy carbs, the empty airbox, the incorrect battery, the pinholes in the rusty gas tank, basically all the things that hide behind the ‘sold as is’ disclaimer but one should never expect to find on a frame up re-conditioning. It has, however, been a deep learning experience, that showed me exactly how not to present a motorcycle.

I know the question on everyone’s mind is simply- Did you contact the seller? I meant to, but I kept thinking, well it’s just this or just that and I’ll have it fixed in a jiffy and maybe I’ll contact him later and ask for a contribution to the fixes, but as the problems mounted I simply only cared about getting them fixed and that window closed. I did a little research and saw that any negative reviews were met with swift and merciless attacks with the victims suffering further by being portrayed as the wrongdoer. I wanted no part of that dance. Nothing I learned lead me to believe that anything I did would result in a remedy that would leave either of us satisfied, and again the defense would be the all encapsulating sold ‘as is’.

All that being said, I’ve collected seven bikes from the fabulous E-bay and honestly this has been the only purchase that really ran against the grain of what I was expecting, and in the end I turned it around.

Will I do it again?

You know.

 

Running…

 

“There’s nae spark Captain!” Apr ‘22

Rolling the H2C onto the lift to refit the calipers reminded me of the blood sweat and almost tears it cost me when it unceremoniously flat cut out on the way back from the supermarket one night last summer. Some thirty kicks later, a push up a long hill a roll down the other side and bump start in second got it going again which doesn’t make it sound electrical, but I think it is.

Fast forward to tonight, I took the plugs out and kicked it over just to make sure that was no oil or fuel in the crankcase and out of curiosity dimmed the garage lights to see if I could see what the spark was like. It went from intermittent to not at all. Bikes been on a tender. It’s got lights and flashers.
