Slavens head mod

I run a Slavens high compression head on my 250sx and have not had to use any race gas in Moab. I think we are good untill we get below about 3,000 ft. If you like the power at Left Hand, you will LOVE the power when in Moab. The lower you go the more power you will have. You will be able to idle up hills when in Moab!!!!

That's scary. Definitely going to be gearing up some. Maybe even give the green PV a shot. Thanks.

Btw.. don't you guys have a RR you should be posting up?

I'm itching to try out my new SXS head. Rampart or Divide on 4/27? Springs was sunny today while we were getting dumped on.

Jetting - RF, Tom?

So.. the GJ enduro looks like it's all around 4800-5200 and forecast at 70. Anyone with have some jetting suggestions for me with the Slavens head?

The JD sheet says Blue needle clip #2 + 162 main. When I was down in NM (still stock head) I ran touch leaner with Red needle clip #3 + 162 main and it seemed great (and it was colder). Already swapped to the 162.. trying to decide between blue vs red....

165 and bump the needle one clip pos richer. I think the blue (not sure of the position) is the next richer needle needle position, it jumps back and forth between the 2 depending on the clip position, I don't have the chart handy though and I'm headed out to work, sorry. Good luck and don't forget the taller gearing

Thanks. I ended up going with the JD recommended (blue #2, 162 main) + doing 50/50 pump & VP110 gas.

Found out I don't have the 50t rear sitting around that I thought I did. Just going to see if I can round up a 14t to swap on the front tomorrow.

I think it helps to bump the main slightly with that head but I'm runnin "casual" gas.

Race gas should more than make up for it though.

Interesting.. Jeff S was telling me I could go leaner (higher comp = more complete burn), but I'm not that brave.. especially given that we could find some deep sand in places.

Fingers crossed.

First time on a trail with the 300. Quite a different throttle response than the XR400 I have a root in the trail I rode that I have come to call the wheelie root, I look forward to it, on the XR I stand up and compress the suspension, as it releases I crack the throttle and whip out a cool little wheelie. I'm so glad I was alone, on the 300 I stood up and compressed the suspension, cracked the throttle and rode an uncontrolled wheelie into the timber straight off the trail until in a desperate act of self defense I flung myself from the bike. My index and middle fingers on my left hand look like little swollen black bananas, this bike has a Rekluse, is that coincidence

Going to take a little time but I think we will learn to get along just fine.

PS - First tracks of the year on that trail - gotta love that.

Awesome!

IMO the throttle response at the bottom-end takes some learning, coming from a 4 stroke. I still haven't mastered the perfect amount of 'blip', but I'm getting there.

Congrats on the new 300! First tracks on the trail is great too!

Going to take me a little time to master that perfect amount of 'blip' for sure

What I was told to do by a more experienced two stroke rider, was to cover the clutch; fan the clutch to control when/how much power gets to the rear wheel is just as important if not more so, than turning the throttle. This technique is hard to learn coming from a 4 stroke where you just ham fist the throttle to speed up and slow down (engine braking). Short bursts, fanning, blipping, rear brake, brap brap, cut, stand the bike up and power out of corners. Ya gots to ride more aggressive, maybe that's why it's more fun, plus the sound. Braaap Braaap.

All good points, I told myself how it was going to be different but my muscle memory just took over when I got on the trail, I chopped the throttle going into a downhill turn and expected the bike to slow down A few more hours on this thing and I think I'm going to love it, can't wait.
