All my testing is on dirt. We tried to find some pavement but none were safe for a full test.

Nowakaw650, I couldnt believe what a time difference I had in 4wd. You are right about 4wd and the P650/700. I hope that red 400ex shows back up on Sunday. Things will be different this time.

 

Got some testing done today. Tested for 6 hours, for a total of 38 miles and almost a tank of gas. Im not sure how may runs we did because I didnt figure anything up yet. We still have 3 springs left to test and hopefully the rain will hold off tomorrow. I put the Dalton blue spring in at the end and did a test ride with it. I dont mean to offend anyone but all I can say is I wouldnt kick a dog in the a$$ for that spring. Although it has good hold back on hills it slows me down way to much when letting off the gas on level ground and I could only get 61mph on level hardtop surface where as I could get 64 with the stock spring and EPI B/G spring.

The big suprise of the day came from the stock P700 spring. To catch the results of this spring and others look for a full blown out test Monday evening.

 

i've narrowed my spring choices to the stock p700 or the EPI Pink. I'm IMPATIENTLY awaiting your results [img]i/expressions/face-icon-small-happy.gif[/img]

No offense taken with regards to our blue spring KOD,But the very same thing that hurts top end on a prairie(high top end RPM),actually helps top end on a V-force..(its intended purpose). Unless of course you were to tune the rest of your clutching accordingly,and or change change the shift ratio with large oversize tires. I know of one 650 p in particular (with some light engine mods)that i tested until 9.30 last night ....it turned 5.95 in 300'....that would gladly "kick a dog in the ***" for the blue spring that is in it.

 

Helix - who's 650 was the machine you tested? Probably someone I know. BTW - Helix's 300 foot dragstrip uses timing lights; no stopwatch operator error involved.

 

Helix, I know in the post above that he said the plain/white gave awesome result's....why does the "softer" plain white at 114 lbs, finish perform better than the "stiffer" blue at 155 lbs finish???I do have a 700 Pra. and the clutching is set-up like the V-Force, with the same primary and secondary but with different fly weight's than the V, since the cam timing on the Pra is set for lower rpm"torque" I am assuming the Plain/white will work better than the blue on both the 650/700 Prairie's, right, don't have the fund's for the matching weight's yet, just want a little better acceleration than stock.....

 

Hey stakk I just sent you a private message. I tried the HPD silver/gold spring today in the V with really good results. I dry-wiped a heavily modded raptor at both 100 and 250 yds. about 10 times. I have Duncan duals and 152/148 jetting with snorkel removed.

 

Got it, sent you a reply.......

 

Stakk,
I remember seeing a post you made some time ago that you did not see the advantage of an extra 50cc what made you trade off your 650 for a P700 LOL. I traded my 650 also so I am going to play with the P700 to see what I can do with it. If you wish send me your clutch I will moddify it for you.

 

Alltoy's, I really did not see the advantage until I rode a 650 and then a 700 back to back, since you have one now to, I guess you know why also......I was going to trade for a 04 model regardless of whether it was still a 650 or 700, the extra cc's were just a bonus, The 02 650 had 3000 miles on it and the 03 and especially this 700 have a better and more refined clutch and belt set-up, so I went for it, I guess I am going to put the spring's in for the same reason I did the 650 better belt wear, and the aftermarket spring's just "feel" harder hitting and better throttle response, warranty is still on for several month's before i start re-doing the clutch's, I already like the performance of this 700 in stock form way better than my 650 was stock........
