I have a 86 trx and wondering if I can run 88 a arms on them also can I run 400ex a arms on it also

 

Yes the a-arms on the 88 will work with your 86. I don't believe the 400EX a-arms wiil work though.

 

you can use 400ex a-arms on a 250r. i have +2+1 a-rms off a 400ex on my 250r i'm building right now. you do have to use spacers though

 

mxquadracing, i have everything that you have except the LSR chassis. do you like the setup, is it of as good of quality as the rest of the stuff. how does the LRD motor perform

Thanks

 

I love the LSR chassis. The quality is just as good as the other aftermarket companies. I don't know much about them though, all of my friends either have LSR, or Laeger's.
I love my LRD motor. It has been a very reliable, as well as competitive. I just sent it off to have it bored for a new piston. (Pro-X of course.) It should make it through the season. Next year I'll have to have it resleeved.
