Travelor,

1) What tire/wheel set up are you running?
2) At 80mph how is the stability with your set up?

 

I was using the stock tires and rims. It is a little scarey on the gravel road with gravel ridges. Just lean down and hang on.

 

HAD MINE UP TO 95 IN THE BACK OF MY PICKUP

 

HAHA!!!!!

 

Travelor,
Please forgive me in doughting your word but 80 on gravel with stock set up even on a BF 750? I see you have a machined clutch, that in concideration the part I am having a problem with is gravel. The gearing between my quad and yours is minimal for me get anywhere near 80 I have to use V-Force gearing and a V-Force has a hard time coming close to that speed at 200#'s lighter than a BF. With this next answer you can varify or at least bring to more of an understanding for me if you would? Since you have a tiny tach what was the rpm when you reached the top speed?

If you had a GPS to show your actual speed that may differ from speedo. I don't mean to dought your word but you must agree it seems to be exceptional. If so great for you, you have one exceptional machine!!!!!

 

I was on a slight hill, got 75 going up and 80 down. the groung was still a little froze. The bike would run 76 max before but it was always below freezing. When 50* ,ran better. The tac said 8700 but i think it was before the 80 mph. I think the power band is at 7400.

 

The same day, I tried bike with stock cdi, topped out 68. I am sure it would be actually a few miles per hour high on stock speedometer. Will try gps sometime.

 

Travelor,
Thanks for the reply in all honesty I had some impressive numbers on gravel I did live in the country and my test track was the road in front of my house, lol. Numbers on the speedo did not match the numbers on the GPS, wheel slippage mostly. Frozen ground does help but then there is ice between the patchs of the gravel so again slippage. Try pavement with a GPS and stock tires/rims then you will have the truest representation your quad will do. Even if I could make my quad do 80 on gravel I would think twice about it as the consequences would be irrversible if something went wrong you know Murphy's Law!!!!!

 

Tried top speed again on same gravel road. 76 up the hill and 78 down at 8635 rpm. 66 mph = 7400 rpm. Tried gps, it is so slow to catch up but seems to be 3 mph less. Hard to hang on and hold gps going 78 on gravel road. Then switched to 26" mud lights with type6 rims. Slowed it down where I was at 68 now 64, topped out 71 mph on speedometer. Tires seem to be about 2 mph diff. so I can say I lost 5 mph. Maybe if i pull a rivit out of weights ,it may pull better.

 

I saw a guy this past weekend say he got a Brute to 78 on speedo b4 he let out. Brute had 1 hr on it. I offered to race, but he declined. Seemed fishy?

My P700 runs 74 alone.....76 drafting behind my buddies raptor (according to the speedo). With 26" mudlites it ran 70-71mph.

I have the dyna cdi, and they advertise higher rpm limit. AT 76 I am hitting the rev limiter. Does this sound right?
