I have been out of town this weekend, thanks for the replys. I rode the 450 Friday (it's a '72, not sure what model). It's in really nice shape. All it needs is a pair of rear shocks that work a little better. I was suprised how it rode. It was slow to rev but very fast once it got going. I expected more torque down low. The 250 seemed faster off the bottom, but ran out of power a little quicker. Is this pretty typical? How should the 450 run? You couldn't just wick it off the bottom and pull the front wheel, it had to be up in the revs.
It does have a bing carb, what do you mean tickle it? Do many people change the carb to a mikuni to improve performance? The guy said he changed the cylinder head to lower compression a little, to make it easier to start, maybe that's why the performance isn't there.
Thanks for the input on the 250. When I rode it friday, the suspension seemed a little soft. I'm only 175, so that kinda surprised me. Since I don't have any experience with these bikes I didn't know what to expect. The only thing I have to compare it to is my KDX and it was WAY softer than that. I'll check the websites you mentioned. I look forward to riding it more extensively. Any other input or discussion would be great, I'm like a sponge right now, I want to know more :worship:
