1" pvc spacers in both front forks and a DNM rear shock would probably be the cheapest route

 

Agree. You can also run ATF fluid in front forks, 1oz more than manual calls for (i forget what it is) - no spacers needed. I'm 175 and ride moderately to aggressive - I'm not skying the bike but the ATF creates a nice plush yet firm ride with good dampening.

You say ATF referring to automatic transmission fluid? Thanks !

 

Don't do that. Thicker oil will just affect the rebound, dampening etc.

I know people have done this with ATF, but why? They sell other weights of fork oil... Just do it right for christ sake!

All you need to do is put a 1" long pvc spacer on-top of the spring in each fork, then reinstall the cap. You'll be very happy with the result.

If that for some reason isn't enough, time to get BBR HD fork springs or inverted forks.

 

ATF was sold by dealers as fork oil for LONG time. It has anti-foaming characters which is needed for forks. The weight is roughly 20W, so yes it does "slow" the fork's compression /rebound but by adding an additional oz you also firm up the fork. Give it a try before you comment. And if you really want to reduce the rate even more use hydraulic fluid ))

 

So I Actually picked up a kx 65 for 100 bucks whole bike everything there now I’m going to use the forks from it with a simple bearing swap but now what swingarm should I use for cheap can I fan one of my one use the 65 swingarm or what?

 

Also on the bearing swap I see there is a 100 dollar kit but can’t I just buy the bearing from all balls for 40??

 

Do a search for kx65 fork swap - lots of info and even more options. You can use the kx65 entire front end, including stem without the $100 kit!!! But it requires a little fabrication and you only need to purchase two kx65 taper bearings for about 20 bucks on ebay. Simply grind the ledge from under the lower bearing so that the bearing sits flat on lower tree. Doing this removes .200 which raises the stem enough to fully screw on the upper tree. I've done this using a 2004 RM65 front end - no issues.

 

Ok thanks I’ll do that for the forks what about for swingarm how about x4r I just need a way to relocate shock mount??

 

I'm not much help there....I extended my stocker by +2.5 by cutting off the rear tabs where the axle bolt goes and welding new (longer) ones on. Good luck!!

 

If you are really good at fab work you could put the whole kx65 rear end on and you will have a linkage rear suspension. It has been done before on here, I think Art5 had pics of it on one of his threads.

 

Sitting here reading this post is cracking me up. So here is the deal: 1 ATF WILL work. It is nothing more than an anti-foaming hydraulic fluid. And it is around the 20 weight. The newer "suspension fluids" were designed to fine tune the weight needed to work with the valving settup. Here is where it gets funny... You guys are talking about putting spacers in the front forks. Well when you do so it creates a positive force on your rebound stroke. the fork springs are designed so that at full extension there should be no force against the fork cap. So when you add spacers not only are you creating a pogo stick effect, you are also really messing with the rebound. So in theory you SHOULD add a higher viscosity fluid to help slow the rebound down some. The correct way to add spacers would to be to cut about 2-3 inches off of the spring and then add in an equal amount of spacer. that way you aren't adding negative force to your rebound by shortening the spring length you are increasing the rate. Then follow up with atf or the fluid of your choice. The best setting I have found so far is 25 weight and adding 3 ounces to the factory specs. As for rear shock I agree the fast ace for the money is a decent upgrade provided its the model with a reservoir.

 

Did you ever end up getting all this swapped over on the bike?
