Technical / Re: 2003 YZ250 front suspension

« on: June 29, 2010, 06:14:09 PM »

You have steel springs in your forks that should support the front end regardless of the condition of the fork seals. I once restored a 1983 Maico MC250 that had been beat so hard that the previous owner had managed to break both front fork springs.Sounds like you need to carefully overhaul your front forks.

You were right. the springs werent broke but measured almost an inch short. thanks. how do you go about pickin what spring to go with? im a big dude. that mean i should go with a heavier spring? thanks again

I blew something in my front suspension. I can lean on the handlebars and bottom the suspension out. i know that i blew the fork seals. Ive replaced fork seals before. no prob. my question is, is this normal for blowing the fork seals? or more like i blew something else? thanks
