I have a 2001 stock 400ex and was wondering if anyone would have a suggestion on how tight I should run the rear coil spring. I have it curently about 2/3rds screwed down. I am talking about the two threaded rings right above the spring itself and not the compression adjustment. I am about 150lbs and ride in heavy rocked woods. So if anyone has a starting point that I can tweak from there it would be appreciated.
