Right there IS the Mach111, the first-year, drum brake, and in White, it doesn't get more perfect than this, you should be very proud of what you have achieved, and I reckon it's worth a few bob too.
At 15 years of age, I challenged my cousin to a quarter mile drag race, on my brother's 1969 mach 3. The cousin was aboard a 1969 BSA rocket 3. The first run was a fail on my part, because I shifted into 2nd gear to early, during it's peak torque rpm. It stood straight up, so I had to depress the rear brake to regain control. The second attempt was a success as I achieved red-line through all gears. I defeated the rocket3 by at least three bike links. Had we continued for another 8th of a mile though, the Rocket 3 would've reigned victorious.
I shouldn't have said "correct low ignition cover." Rather it is the "original low ignition/oil pump cover." All 1969 and early 1970 CDI H1's came from the factory with the "low" cover. After engine #8800, Kawasaki moved to the "high" cover and offered to replace the cover on the earlier bikes. see Kawasaki Special Service News Bulletin #H-3 dated February 6, 1970. Hope that clarifies the comment!
Only issue I had with mine was the cranks built in tendency to " twist " on the stepped big end pins and crank - wheel centres ( alot when modified ) Huge problem on the cdi / single coil / distributor version . Ended up rebuilding in stages to allow tig welding of the offending parts . 32mm carbs , H1R ex John Woodley pipes ( allegedly ) , H2 disc front end & later oval section ( longer I think ) swing arm . Was torquey as hell and still managed 12 flat at 110mph in 1977 ; won good money on that thing and like most bikes I've owned I shoulda kept it ...
