Hi Rick,
Those were my thoughts exactly when I first got the GG. I had the KTM for a while (6 months) and had tried about 5 different pipes on it and settled on the Doma (by far the best for my riding) and had the jetting very good also. I live on a 2700' grass runway at an airport so we took them out (with my boys) and "run" them(I can do that because I own it so dont try this at your local airport). I thought that my son was riding the GG wrong so we changed between bikes and the results were the same. I thought that it had to be jetting or something, and so did Jim at Smackover. I tried many jetting combos (running LTR kit now) and got it better but still the same results.
The Gearing on the two bikes is very different so I am not talking about flat out runs (ktm goes 83 to 88 depending on pipe that I am running, and the GG does about 70 tops according to my computer) we are talking about runs up to about 60, and the difference was 5 or more (maybe 7 or more) bike lenghts.
I have given much time and thought to the "problem" and came to a few conclusions.
1. The sod runway is not exactly like "real life" racing in the dirt, so might be a little skewed.
2. There are a number of factors that play into the outcome, one is the flywheel, the GG has a lot more and thus does not rev a quickly.
3. The pipe on the 200 is the same as the other GG's I have heard and so there has to be a compromise there. ( talked to Doma and they have pipes for the 250, and 300 but not the 200. They are tring to get a hold of a 200 and wil then build me a pipe and I think that would really free things up).
4. Porting is a lot different on the two bikes.
That all said, when we get into the tight woods I can go faster on the GG (and my sons also, they make me ride the KTM, and they fight over the GG) so I am not dogging the GG, in fact I am waiting on the GG 4 stroke as my next bike I think...
5. I will pull the topend off this winter and see if ther is something "wrong" in the GG but I do not think so.( the only thing that I have had to do to the GG is change the shift shaft were it fell over while warming up and somehow bent. and that was only about 85.00 with gaskets and shipping)
If you are at dirtweek 2002 I will let you ride them both and you can judge and see if it is just my GG or not (compared to yours).
For you info My GG is about as fast in a drag as my older "woodsed" KX 250.
I am not trying to start anything either, just what I find with my bikes
Thanks
Vern
