No definet answer, but I'm hearing around the middle of summer 05'. Hopefully it's worth the wait.

 

Is the new Suzuki suposed to be a big bore quad like the Raptor or another high performance chain saw like the 450s? Reverse??? I am curious.

 

450 based on the rmz450 bike they released a few months back. Reverse is up in the air. Sales would be higher and they could steal market share since the vast majority of the yfz and trx riders are recreational anyway and dont care about the weight savings. Some woods racers would probably like it too. But they could go the pure race bike way and maybe even show up the yfz on a race ready standard. Standard kick w/ electric and a good, light frame would go pretty far too.

 

I didn't know I was riding a high performance chain saw.[img]i/expressions/face-icon-small-happy.gif[/img] I think it's a safe bet that the Suzuki will make the YFZ its main target, meaning no reverse, 450cc, and one more chain saw to deal with!!!

 

The yfz can only beat a raptor when its stock for stock for a short race...
A 686 raptor would beat the hell out of the poor piped yfz from the beginning and till the end of the race, no surprising from the yfz will appear this short/drag race.
come on whats even the question...

 

I have been there done that. A properly tuned, cam modded, intake, piped YFZ can beat a 686. The Raptor can be bad A. But so can the YFZ. I think the performance potential of the YFZ is going to surprise alot of people once the engine builders get into full swing. Keep in mind that the YFZ needs less hp than a Raptor to have equal acceleration.

 

I'm not about to see this thread take the route that the last thread like this did. Yes, a properly tuned yfz as you described can beat A 686. Properly tune a 686 with the upgrades like cam, valve springs, porting, etc that that kind of build requires, and you will have a different story. You have to specify what kind of 686 you are beating. There are plenty of stock bore raptors that can beat a yfz like the one you cited when built correctly. It's all about the build.

 

So, if you have 686, 11:1, stage ? cam, ported/polished, full exhaust, what will be the difference in power from builder to builder?

They are all installing similar parts with similar specs.

Jetting is really the only variable, right?

 

There is a 686 out of Billings with something like stage 2 cam 11-1 pretty mild porting and bigger intake valves, he was racing up Choke Cherry (where the Raptor weight really shows up) and beat my YFZ (air lid off 165 main baffle out) easily. A few lengths by the top of the hill. There were a couple of YFZ's that would hang with him but they had some unknown internal mods I think.

 

Unknown internal mods? How did you know about the internal mods that he had done in the first place? Did you do the cam mod to your yfz? Sounds like you are making excuses. If he was flat out blowing you away thats one thing. But if it was a couple of lengths you have to face the fact that you just may have been beat.
