hi im a hevier guy at 240lbs i have no problem with the bike except i notice when i close the throttle the front end drops dramatically and i cant find any adjustment???

Define dramatically.

I'm sitting at 215 and at high speeds I end up dipping in the front as well when closing the throttle. It doesn't seem drastic in most cases, it is directly proportional to how fast I was going. It's all about the transference of weight and the change in the center of gravity. At least that's my take on it.

With the engine breaking along with the instant decrease in throttle input that transfer of weight would probably feel pretty significant.

I weigh the same, but I don't notice any dramatic drop in the front end. Maybe you're putting excessive weight on the handlebars. I hold the grips tight, but don't really put any downward pressure.

by dramatic i mean like two inches of play on the forks between open and closed throttle and most any speed.. is there any adjustment at all?? would stiffening the back help the transfer of weight at all

Stiffening the back I don't think will help the front forks any, and no there's no adjustment for front. Only option is upgrading the front.

When you ride do you lean forward or "lay down" on the tank? if so this could be a reason why...releasing throttle will slow down forward motion but if your body is over the center of the bike to the front this would explain a "drastic" dip. I find that curving your back (chest against tank and then pulling shoulders back) is the best way to avoid an dramatic dip

I'm 250lbs and don't notice anything dramatic dip in front like you state. So maybe is your riding position like others mentioned. Also might be grabbing more front brake than you need

i went out today and tried to make the front end dive the only thing that would make my bike dive is if i was ripping in 5th or 6th gear and i completely closed the throttle thats the only thing i could think of that would make it dive that or rippin on the brake. try a different stance with a smoother throttle response (unless its an emergency stop) theres no reason to completely close the throttle at that speed

So i went riding witht he crew today (5 leader bikes and me haha) had a great time went on a 60 mile run. We decided to see the difference in acceleration since we all know top speed on a leader will kill our bikes but regardless it was fun to fool around. any way started on an onramp dead stop holding clutch and rippin on the throttle. Release throttle and off we go now I'm sure you've all seen how rider shifts when racing (not pretty) Long story short the front end did dive but not so much to cause any concern. I ended up loosing lol but it was a blast. And before anyone says it I know what im doing I've dragged before
