i bought a 08 1000 cbr that has been lowered before i bought it. the trees were dropped as low as they can go without modifying them. the rear was done with a lowering link. so i cant put a passenger on the bike with me because it squats so bad that the plate hits the tire.

how can i raise up the back end some and put a preload on the spring so i can put a passenger on the bike? im not going to ride a passenger all the time, but as a single guy id like to throw a girly up there. lol! im kinda mechanically inclined but wonder if i should just pay someone to help me with it.... HELP! LOL

 

Do you want to put it back to stock height? If so, just buy an oem rear link and you should be all set. The hardest part is supporting the bike while you change the link. if you have a garage, you can use two straps attached to the passenger footpegs. You may also beable to have couple of friend support the bike while you change it out. Just be careful, there is quite a bit of weight there. The preload is adjusted by the spring on the rear shock.

If you check ebay, you will see there are adjustable links as well. It allows you to raise and lower the rear simply by turning the adjuster.

For the front, its the same thing. Just loosen the triple tree while you have the front supported and lower the forks in the clamp. Make sure they are even.

Keep in mind though, if you change the height of the bike, the kickstand will have to change with it.

If you are tall enough to ride the bike at its stock height, you really should get it back to that height. Cruising and just commuting are ok with a lowered bike, but once you begin to get aggressive, they can become quite upset. The other issue with the handling of the bike that is lowered is panic maneuvers. The bike may not react the way it should which could result in a crash.

 

thanks for that insight. yes i can support it from the beams in my garage. im ok with it being lowered and driving aggressively, it hasnt shown me anything that i cant handle. i really only have seen 2 things about this beast that i dont like and i think if i can stiffen up the rear spring it will fix those issues. i cant ride a passenger because of it sagging, and its a wheelie monster in the first 3 gears, thats why i needed to know about pre loading the spring. do i have to remove the rear tire to pre load the spring? and what is the rule of thumb with say a full turn on the pre load adjustment? thanks again for your help!
