I have helis and notice a huge difference when I mount them under rather than over the triple.

Over is a VFR... under is a CBR.

Lots of other mods have helped; you should say what you have on you bike (stock forks, shock, etc). You need fork springs, thicker oil, and a shock spacer. It will be like a new bike.

 

i will set the sag this weekend, been meaning to do this for a while... 8541hawk do u mean put the front 5mm down so the front is lower than the rear? if anybody would be like to be so kind to measure stock height of the front it would be greatly appreciated. i have racetech springs and valves and FG gubellini rear shock setup up for a 170lbs even though im only 145lbs. i bought the bike this yr. so im trying to chase settings. also, i need to change the fork oil...not sure when it was last service. smokinjoe maybe ill try your setup with the heli under the triple tree ...ill let u know how i make out

 

Remember to be fully geared up or place all your gear on the bike when you set sag

 

Thats a pretty big desparity in wt. You are barely gonna compress the spring. You can go to the penske shock web site to see the different spring rates for diff wts.
