currently both moto & scoot have last fall's frankenbrew of 10w-40 & 15w-40 oils reinforced with Amsoil OE 15w-40 synthetic; both machines only have 250-350 miles so next oil changes will be in a few months once I get 750-1000 miles (might keep current oil filters in use -- moto has fram 6004 & scoot has hiflo hf183); new oil is another frankenbrew of 10w-40 & 15w-40 oils with Amsoil 15w-40 synthetic (new ck-4 spec) -- 1 qt Amsoil to 3qts frankenbrew; moto will get yamaha oem filter & scoot gets hiflo hf183

Most recent oil change in the 2001 ZRX1200, out with Mobil 1 10w40 4T Racing and in with Mobil 1 20w50 Vtwin. Use Hi-Flo filters each change. Either of those oils is a top choice for minimal shear (maintains shift quality) over a 5000 mile OCI.
I used to go with 15w40 HDEO's, shift quality fell off after 3000-3500 miles versus the fine shift quality still remaining at almost 5000 miles with a good syn MC specific oil. I could have legitimately left the M1 10w40 4T in for another 2000 miles or more given shift quality and the TBN remaining was 6.5. No dino HDEO is doing that, promise.

Fork oil change
Out: OEM (bike has <8k miles on it)
In: Valvoline Maxlife Full Synthetic Multi-Vehicle ATF (KV40: 28.82cst, VI: 156)
Previously swapped out the rear links for a 2" rise in the rear. The forks were diving more than I cared for, so I swapped the spacer tube (5.875" steel tube) for a 6.25" PVC tube (0.375" extension) to add preload. Swapped fork oil for something with less dampening than the SS-47. Took it for a ride, and all is good!

Mesh filter (cleaned/reused)
About 8 hours on the old oil, it looked clean in the drain pan and felt like it was maintaining viscosity well. Just an eyeball gauge here of course.

Honda GN 10w30 - factory fill
Flushed early on, had a few very small chunks and a bit of flashing.
Don't want this stuff floating around in the engine (with just a gravel screen).
