I'm trying to restore a '78 IT400. The old bikes called for 20:1 in the gas and 10W-30W 'SE' type in the gearbox. The newer 50:1 oils confused me, but I finally opted for 32:1 castor in the gas and it worked fine.
For the gearbox I chose 80W gear saver after asking questions locally. It seems okay too, but my recently adjusted clutch is already running out of adjustment so I'm wondering if the different viscosity effected it --- of if the clutch is just going (no slipping yet; engagement is just all the way at the end of the travel).
My main question goes back to the fuel mix though. I'm about to pull the top end and overbore. My Clymers (which calls for 20:1 in the tank) says I should run 16:1 during break in. I'll be breaking in after the cylinder bore, and am not sure what to run then since the newer oils don't run at 20:1 to start with :| :think: This really shouldn't be so complicated!
To complicate further, I saw Klotz oil for sale at Pro Flow and ordered a case of original Techniplate. It should arrive soon. But NOW I'm wondering what blasted ratio to run it at! Is it an older formula that I should return to 20:1 with?
