fun_on_the_sand Posted September 15, 2006 Report Posted September 15, 2006 Hi guys I have the programable LS Dyna on my shee for a while, but since I got it I have always used the "stock" curve for cruising, dunning and racing... Can anyone explain to me what type of riding is every curve for? or what kind of power band I can get on every curve? I know the different curves change the timing on different rmp ranges, how does timing affects the power? the more advanced the more power? what do you sacrifice when you advance the timing? Thank you Quote
Bansh-eman Posted September 15, 2006 Report Posted September 15, 2006 you can go to dynas website and it explains the timing for each curve... when you advance the timing you gain more top end and when you retard the timing you gain more bottom end. Quote

Thank's for the timing explanation. Do you have one of this? if so, what curve do use for dunning and which for racing? Quote
fun_on_the_sand Posted September 16, 2006 Author Report Posted September 16, 2006 Come'on guys I need some help on this... I would like to save some time under the sun of Phoenix and race gas by not testing all 4 curves by my self. Quote
Bansh-eman Posted September 16, 2006 Report Posted September 16, 2006 i havent got a chance to run y new dyna yet.. im going out columbus weekend to mexico to ride it for the frist time on the new cdi Quote
wesw Posted September 16, 2006 Report Posted September 16, 2006 i would say try curve 3 and see how it runs. curve 4 might be to much with your compression. depends on compression and fuel. Quote

That's 180 backwards... More timing is more bottom, less top. Less timing is less bottom, more top. I use Curve 3 on mine all day long...plus I have a timing plate set at 8 degrees as well. Wes...Curve 4 is stock. Curve 3 offers the most overall timing. Curve 1 starts the advance earlier in the RPM...but it tapers off as well. Curve 2 is just a slight bump... I say play with curve 1 and 3, see which you like the best. in 300ft sand drags, I ran my best times (not by much at all) with it on 3. Quote

dajogejr Posted September 17, 2006 Report Posted September 17, 2006 Thats sounds like quite alot of timing advance! Yep...it is...and my cub LOVES it...as long as you stay below 30 degrees or so of total advance, you're ok... However, once I switch to the booze for my motor, it's gonna have to be backed off a bit!! Quote
