Replacing Dogbones - Suspension question

So the bike I will most likely be purchasing is lowered via dogbones, now the owner has the stock dog bones so that's good.

My question is how hard is it to replace them with the stockers? From what I gather its not difficult at all.

Also, I'm quite a heavy rider currently sitting around 295ish what are some things I need to do to the suspension?

New spring to accept my weight? and have the forks re-valved?

Re: Replacing Dogbones - Suspension question

dog bones are easy swap. you just need to support the tail when you take them out. you can get used springs for around 50 bucks. actually i may have a 6 inch #600 spring i took off an elka shock. if it was me i would respring the front and back. for less than 200 it would make a huge difference in the bike.

Can you elaborate on the "oil in the forks"?

Re: Replacing Dogbones - Suspension question

well if you change the springs in the forks to suit your weight. put new oil in and put an exact measured amount as per the service manual. chocolate rain has a link in his signature to the service manual

Re: Replacing Dogbones - Suspension question

K, I was just not understanding correctly then. I figured you meant there was specific oil for different weights of riders, kind of like viscosity.

I already d/l the service manual..(Y)

Do you happen to have the matching front springs to go along with that rear one? Also, how big a of a job is it to replace the springs in the fork? I'm assuming if I'm asking that I shouldn't be attempting it but I'm quite mechanically versed with cars, just not bikes.

Re: Replacing Dogbones - Suspension question

you can play with viscosity too but easiest to just put in what the manual says. but i just use 10w non detergent oil. cause i had it and its 3 bucks a liter and fork oil is lik 30. i have used 30w oil in the gf's ex 500 forks as that is what the ex racers use.
