Hi Lucky,
You will be limited by available space making it nearly impossible to add excessive weight. Determine the physical limitations and shoot for as much mass as feasably possible. 12 - 16 OZ comes to mind.
Hope this helps.
Kind Regards,
Dale

lucky;
i know what you are saying. sometimes the bike is stronger than the rider's ability to hold on. i have an 02 650 and its pretty brutal at times also.
i notice a big difference when i use the hi/low switch which controls the ignition advance curve. do you use the switch?
also, you may want to change your gearing a bit. try adding 1 tooth on the front sprocket, i believe its like removing 3 from the rear sprocket.
maybe these ideas will help tame the beast, or at least make it bite back less.
on a side note...i rode a new cfr450f and that thing rips out of your hands very easily. alot of throttle control is required to ride it correctly. i hit the gas to get the front wheel going up before a bump and gave it to much gas. the bike 'launched' over the bump. looked good but it wasnt what i was expecting.
hope this helps

Flywheel weight
I added 12 ounces to my FE400e and it tamed it considerably. I am thinking of removing perhaps 1 or 2 of those ounces to get back a bit of the hit, but overall it was a good move. The tractor idling around got better with no more stalls. I'm still running stock gearing. STEALY did it in Southern Oregon. Any good machinist could get there. They do a skin pass on the flywheel to make more room for the brass ring and them shrink fit the brass. I had it done to a new flywheel so I have the old one I think I can put back on for OEM results, but I haven't tried that yet. I would recommend it, but you may also just be happier with a 450. (I'm not sure how anyone hangs onto a bike in the dirt with that much horespower anyway). Regards, BD
