What have I done?

Hillclimb#42:
The first year or two that I owned my 250, I thought and said many times that I would have been better off with a 125. That 250 rips. After riding it for 4-5 years and making it faster a little at a time, I went nuts and bought a 500. I will probably never ride it over 70% and it will still be very unsafe. Its like the roller-coaster affect. When its over, you realize that it was a blast. You are freakin' so hard that you are on that much power that you really focus in on every obstacle, every sound, every gear shift, until you park it. Then you realize that for the past several hours you totally forgot about all of your daily problems, and the rest of the world. If you were on something easy to ride at a comfortable pace, all of life's stresses are still able to creep in on you.
 I say keep it, figure out what you need to do on gearing and clutch control. You will love that bike soon. Gear down away from stock gearing will slow it down a little. 13-47 is a good gear set-up or even 13-49. That will get you out of first gear and you won't have to clutch so often to keep it running. I kept kllling mine with stock gearing which then wore me out from starting and catching back up to friends.
 Another good thing to do is go riding with guys that are better riders than you are. They will constantly feed you info that took years for them to learn. After riding with them for a little while you'll see how good you are when you go riding with some new guys or guys that you think are on your level.

I would suggest trying a steahly flyweel weight before I gave up on the bike. You can also close the metal reed stoppers on the reedvalve to tame the hit. Move them each 3/8" inward.  There are lots of cheap ways to tame the hit. Cam.

Thanks for the suggestions, fellas.
I will look into this reed spacing thing...

Ordered 13 oz. flywheel, I'll post a ride report after I ride it.  8-)

Well- I promised a ride report...

Rode at Mototown USA last night.

Installed SFB 13 oz. flywheel weight.
The bike starts the same, but idles much better now,, even if not fully warmed.
(This is nice, so I can strap my helmet on and put my goggles & gloves on without the bike stalling.)

The bike is definitely easier to ride now.  Mototown is a pretty tight place,
so I really didn't get to keep WFO too much anywhere, but I must say that it is more manageable
in the turns and in whoops (at least for a novice like me).
Jumping is a much easier as well.

Overall, the change isn't what I would have liked (I would prefer even more effect).
But, I guess the change was worth the money.

Bottom line is, you gotta be in shape to ride this bike, and I ain't in shape.
I am sore today.  This has actually motivated me to start taking care of myself again
after a long hiatus (marraige, comfort, awesome home cookin').

The bike was controllable for the first 1/2 lap or so, but once the fatigue sets in,
it becomes too much of an exercise in restraint and survival.

Look, the bottom line is- if you aren't clearing all the jumps like the fast guys,
the landings are rougher, and your upper body and legs really take a beatin'.

She starting to grow on me now.  She doesn't tolerate couch potatoes like the 4-strokes.
She expects me to match her performance, so let the calisthenics begin.   :-)
