    Never owning a mini with actual hydraulic forks how similar were/are they to the bigger bikes of the day? I put DG air caps on my CR 250 back in the day. They replaced the springs completely. They seemed to do the job then when there was no other options. Any thoughts?

    IMO, suspension technology was primitive in that era; we are talking about designs that are nearing the half-century mark. That said, tall-tire machines were okay. The early hydraulic forks were a big improvement over springers & pogo sticks. Properly setup & tuned, CT70 K1-79 forks are surprisingly good...vastly superior to K0 pogo sticks.

    For the dedicated K0 enthusiast who still wants something better, there are hydraulic cartridges that retain the outwardly stock appearance.

    In scientific terms, you're on-the-mark...unequal vectors will create a lateral torque load that wouldn't exist if both sides had the same springs. That said, the amount of torque should be relatively minimal. K1-style fork legs have wide axle flanges to spread the load. Just keep the axle properly torqued and you should be fine.
