Thanks for the input, fishhead.
re: 'unconclused' ?
I like that!
I did use my -35 with the DFII reed tension set to 'hi'. I didn't notice much difference on the top end of things over the radvalve. Note that is where the radvalve is working its best considering its 45º construction and carbon reeds. My opinion (and proven to my satisfaction anyway) is no intake reed system is going to 'overcome' the tune of the exhaust system on its own limiting end.
But the -30 doesn't 'limit' the bottom end, it just isn't tuned to 'work' there.
An argument that the -35 doesn't limit the topend, it just isn't 'tuned' to 'work' there......is not an apples-to-apples argument.
Thus, I arriveth at the current state of affairs, a -30 with DFII reeds set to 'lo'.
There are two exceptional points made above:
1. (Porter) One thing I've learned from reading this forum is that all of our bikes are slightly different in some way.Of coarse,we as riders,are different.
2. (fishhead) ... temps were unusually warm and humid for this area and time of year. The bike was a lot richer than I expected and it helped me to appreciate some of the difficulties people face when trying to help others with setup or trying to use others info for setup.
Amen!
The general tendancy of 2-strokers seems to be intimidated, skeered or just plain not interested in the 'hassle' of jetting.
That is certainly their loss.
You just can't jet your bike like someone else's and expect it to be correct. There is only one choice, and that is to do it yourself.
I've glossed over a good lot of the detail that is associated with proper jetting. I don't want to scare anyone off from getting started on their own knowledge base of jet-sets by painting too fine a detail. There is not a strong liklihood that you can ride a woods bike in its natural environment for even a single day without some jetting adjustment if you want to keep on the cusp of performance.
Around here, you can easily ride thru a 40º temperature differential and 4000' el. change on one ride! That's not something you'll find in an mx-track race.
BTW, don't take that to mean I worry about that cusp all the time....or even a lot for that matter. I know when the bike is right, when it's not...and probably have a pretty good idea as to the whys and wherefores of its attitude of the moment. It's much more fun when it's right on, but I'm not going to stop by the side of the trail 3-4 times during the day to 'fix' it.
I might tune the day before for what I expect....but that's about it.
I'm looking forward to famerj's pov of the -30/35 hi/lo setups. His conclusions may well differ from mine (see #1 above), but I hope to hear about it anyway.
