I'm game to try, but am also thinking I need to double check my float bowl height as well.
32:1 has 96.8% gasoline to 3.2% oil
Not a huge difference but I can give that a try.
The Shop
MXA mentioned that VP may use Maxima in T2, but they were not officially sure. Then again Maxima makes a range of two stroke oils.
Next time I'm near the shop I'll get 5 gallons of C12. What oils would you recommend that have lower flash points, and that could be run at 32:1?

This setup is to be used with your #8 slide
That Kawasaki NFxx series needle is not one of favorite Series needles. It make the bike hit really hard into the mid, which makes the bike hard to ride. The Suzuki needle will have a smoother transition into the mid with the same on topend.
The bike hits so freaking hard in the middle, even with an 11oz flywheel weight. Plan to do some hare scrambles so a tamer power curve will be nice.
A Suzuki NExx needle will for sure make the bike easier to ride. Have you thought about taking a little timing out of the bike as well to make it easier to ride ? You could also go richer on the starting diameter of the needle. This would also deaden the hit into the middle a little more, but at the expense of some spooge coming out of the silencer, but it would make the bike easier to ride.
I've ridden a new YZ250 smoker and was kind of bored with its power delivery.
Could you comment on a recommended ratio and oil for ideally less spooge, with your recommended jetting above?
I stand with what I mention above still. This will smooth the power out , but not neuter it.

This plug reading is from last ride a month ago (old jetting). It last ran after I idled back to pits following a kinda slow last lap. Also note it was a B7ES. I plan to replace with a fresh B8ES.
Today I tried a gallong of Motul 710 mixed at 32:1, and some Yamalube at 32:1. Both spooged a LOT, but the yamalube was a bit worse.
Spooges worse than before (see 2 posts right above) though.

premix 32:1 (tried Motul 710 and also Yamalube mixed with fresh C12)
Not sure what my next move is....
I don't really have any experience with Motul 2t oils, But I have used Yamalube before. I always found it to run a little dirtier than say Amsoil Dominator, which I currently use, But the wear properties of the Yamalube were always great. the topends always looked good at piston/ring replacement, but there was always a lot of spooge at the jetting settings I liked with it. When you combine the lower flashpoint of the c-12 with the Yamalube, I bet the silencer/swingarm is a mess. I'm not sure how hard you are on the bike rev wise, so you may very well need to use a 2t oil with a lower flashpoint.
How do you like the characteristics of the NExx series needle as compared to the NFxx needle. It should have really smoothed out the low to mid transition, while keeping the same topend feel. I'm pretty confident that your struggle with spooge is not jetting related, when looking at what you are using, jetting wise
Pit Row
Power with the new needle is actually pretty great. It rounded off that toggle switch powerband before. Still pulls super hard, just not as violent from low to mid. I felt more comfortable powering out of corners directly up jumps.
But yeah, I had a little remnants of spooge out the silencer (yep, I repacked it before I rode today) but my guess is this was residual oil in the expansion chamber being pushed out from before.
Note pic below where there was a little drippage at the header, but it crusted up by the end of the day. Also getting some nice bluing on the pipe.
For ref, same jetting as in my last reply. Used Torco GP-7 at 40:1 with half C12 and half pump 93. I'm running a BR7ES plug. May switch that down to a BR8ES if the spooge holds off.
I beleive I have a good combo with 50/50 C12/93 and Torco GP-7 at 40:1 (again with jetting outlined in replies above).
edit: his recommendation for 7 slide was when i was living at 5000 ft elevation in northern nevada, i am in Vegas now and ride between 1800 and sea level and run the 8 and it’s good to go!
I hope this helps
Quit running a 7 to mask problems. Go to 8, such as BR8ECMIX as stock.
With the jetting currently in her bike she shouldn’t have any reason not to run a BR8xx series plug.
Only notable changes are Boyesen reeds on the stock block and R304 silencer.
