Whos going to win?? The 650 will have the mods you see below with the proper jetting, the 700 is a friend that will not change ANYTHING.

 

With either the holeshot module or Dyna cdi, you should be able to take him off the line...but he may catch you eventually. That is just my guess. Good luck to you!

my 650 has no cdi but the dg3, nyroc mod, 142f 145r jets, twin air, shimmed needles

my buddy has 04 twin peaks 700 stock

his will beat me everytime anywhere

very noticable power difference in all areas IMO when I ride it. I would get the 700 or even bigger

I am full throttle most of the time on the 650

On the 700 alot less throttle to do the same

 

I'm afraid he's going to get you.

I noticed considerable improvement on my P650 with EPI pink primary spring on top of the same mods you are doing. Better primary spring would make it a closer race at the very least. I am also considering the 4* key, but am going to wait just a little bit longer for KOD to try it with the dyna cdi.

 

is the pink primary spring one step up from stock. is it close to the 700 stock primary spring

does it start you out at higher rpm or what does it do

 

The pink primary is about 250 rpms higher than stock.

 

Does the pink spring hurt the drivability in technical situations? So is more CCs the only way to keep from being smoked, short of nitrous?[img]i/expressions/face-icon-small-wink.gif[/img] On the trails their will be no challenge (hes a great friend but rides like an OLD lady). Thanks guys

 

Another question, just with the few mods I have (ie holeshot) If I get traction (pavement) I cant keep the front end down even in 4wd high. If I were to raise the rpms at launch wouldnt that make it worse? I lost a race due to this before, at 5mph start I won every time.

 

The pink spring wont hurt your technical areas of riding. The 250 rpm is barely noticeable. It takes around 500 to make a noticable difference. The old saying goes, "there is no replacement for displacement". I think this holds true.

If you raise the rpms it will launch faster. More traction = faster launch.

 

you have to do some serious modding to ta 650 to beat a stock 700.........
