Mick on the Maygo you forgot to mention the brake backing plates that just disintegrate sending their riders head first down the track. Or how good their ignition systems are. And what about the clutch if you dare use it more than once. Then theres the stock rear shocks that dont work. So basically you have a bike that don't start, don't stop and will throw you over the bars with no notice. I have never seen a Maico 490 win one race of any importance in 10 years. They won nothing when new and are still doing the same thing now
Ted you are correct about many of the Maico's short Cummings. Maybe at Classic dirt or similar I could take your 465 for a few laps to turn me? It must be said Ted that most of the mods you insists correctly so that the Maico's needs the 465 needs similar?
On the YZ yes the forks and brakes need little but everything else does.
The Kato needs maybe less than either of these two.
The forks are under sprung and over damped needs springs and valving.
The front brake needs allot of setup or swamped for a Yamaha.
The original Ohlins are fine after a bit of love.
Needs Kawasaki clutch plates and allot of setup for a good feel or after market mechanism.
Yamaha con rod changes the port timing and brings the 390 engine to life and is a easy buy/fit
More than likely after market ignition.
If you can find one an 81 model 125 tank for extra slim feel.
Never had case or frame problems, gear box normally not no issues. The original Bing works fine if you know how to tune them.
