Sep1, do you find that with the newer wheels/tires that the IRS is still a bit tippy climbing big hills or rocky off camber terrain? Or has the wheels/ tires eliminated that problem?

 

I have no problems with tippyness at all. The new wheel/tire combo widens the bike about two inches overall front and back. I do experience the front end comming up when accelerating hard up a steep grade. Just blip the throttle and this sets the front end down again.

 

Brewster, no it probably won't equal the performance of your v-force. You can't expect a much heavier 4x4 quad with virtually the same engine to feel the same as your lighter sport quad. However, it does provide a noticeable increase in response and power.

Are most of you guys rejetting with the DYNA? On the stock engine with stock jetting I saw a gain with the dyna cdi, but for full benefit you really need to give that hot ignition a little more fuel. My carbs were dialed in just right beforehand to compensate for all the extra air with my custom snorkels, however adding the dyna noticeably leaned it out.

 

Lightman,
I didn't have to rejet, in fact the bike runs better with the dyna than it did stock. The only thing I had to adjust was the idle. After installing the cdi, the idle was noticeably higher. I agree with you that the BF750 will never handle like a V. I was just stating that they are close in straight-line performance. Now granted my buds V is completely stock and my BF has a Dyna. I was just trying to negate all the negative press the BF gets about its handling capabilities. The major difference is not the weight but the center of gravity. The BF towers over the V, therefore raising the center of gravity. As we all know the lower the better for handling.

 

Theres a difference between having to rejet and rejetting for the best performance. No you don't have to, but you probably should. The bikes come really lean as it is from the factory for emissions reasons. Leaning it out even more with the cdi isn't necessarily a good thing, even if it does feel snappier.

 

I pulled the plugs and they are on the black side. So I would guess it may actually be a little rich.

 

Sep 1 I saw the same thing, after jetting up to 142-145, my plugs were a little dark, I pulled the plug from the silencer and poped off the little cover in front of the air intake now they are rite on. As I do some mudding and it being wet season here in New England I am going to have to put the cover back on, so I either have to do the Nyros silencer mod or live with it, as I don't want to jet back to stock.

It definatly felt a little sluggish on Saturday before I checked my plugs, but I was ridding at 1000' instead of 100', after I got home did those two changes it feels great now.
