I know I am a new guy here, but I may be able to add a little.
I have owned a 670h.o., and they are fast little sleds, but your 800 (have a 2001 zl800) should walk past the 670.
Mods for the 670 h.o. are hard to come by because they are modded from the factory about as heavily as they can for a production sled.
My 670 would run side by side with a buddies mxz700, but my zl 800 walks the 700.

In my opinion the goodwin kit is a mutch better ballanced kit than the d&d, and their technical support is far better.
been doing the round and round with d&d with my pipe and chip combo on my zr600, finally got it running right, and the parts kick a$$, but their support sucks.

p.s. here is the setup I am using on my 800.

Primary purple spring
Secondary red / white spring (middle hole)
73 gram weights
60 / 52 helix
Stock gearing (2002 stock set-up with helix change)

Glad to find this site,

I don't know guys. All I know is that I lost to this 670 two different times. He got me out of the hole both times and then I couldn't catch up. But, as we approached 90 or so, I started to gain. My sled is running fine and I had good traction. I carried the skis for most of the run. To compare, I am pretty even with my bro's REV800 (this would make me think that everything is fine with mine), but this 670 would even beat my bro's REV. I just think that the 670 is strong. Trust me, this guy is clueless and hasn't performed any mods to his 670.

OK, I can see him pulling a length on you until 90. I had a 01 800 and couldn't shake a 02 polaris 600 until past 70. He could never pull me, but I couldn't pull him either until past 70 mph. You need to race longer if you are going to be stock. You're probably spinning too much. If you want to keep clutching stock and gain a little speed on snow try gearing up a tooth. This will keep you from spinning so much and the 800 has the power to pull it.
