Cam’s KZ750 - Bit Rough, but Runs Right.
This Kawasaki 750 rolled into the workshop for a straight mechanical overhaul—but, as it often goes, things escalated. While the priority was to sort out the internals, we ended up giving it a few thoughtful cosmetic upgrades along the way.
The most noticeable change is the new hand-formed aluminium seat pan and bump stop, complete with integrated taillights and indicators to keep things road legal but sleek. Up front, we fitted a custom fender and fabricated a fresh electrical box to tidy things up under the seat.
On the performance end….
we swapped in a set of Keihin FCR flat-slide carbs, tuned and dialled for street use with K&N filters. At idle, they give off that signature metallic rattle from the slides—angry, loud, and unapologetic. It runs sharp. Real sharp.
We buttoned it all up, test rode it, and the bike was singing. But just as we let it sit overnight for final checks, disaster struck—on morning start-up, the valve cover exploded and the camshaft snapped clean in three pieces. A rare and unlucky failure, but isolated. No bent valves, no deep engine damage.
We sourced new parts, repaired what was needed, and got it back together—stronger than before. The finish isn't flashy and that’s the point. This bike was built to be ridden, not polished. Mechanically sound, responsive, and fun as hell—a classic Japanese four with just enough attitude.
