1985 XR350R with XR600R Suspension?

OK. I've got a 1985 XR350 (from what I've heard, the best year) that I am rebuilding as a vintage enduro. I also have a 1987 XR600R donor bike with no engine. Is there any benefit to putting the 600 forks on the 350? triple tree? rear shock? Will it be a tough swap? Thanks in advance.

The 1987 XR600 forks are nothing to write home about. If you're interested in a good swap and don't need to go USD, try to find a 1987 CR250 fork set or 1991-up XR600 fork set. They're cartridge forks and a step up from the springs on the stick that come with the XR350 and early XR600.

There's lots of post-1991 XR600 fork sets floating around with people doing USD swaps.

One last note, if memory serves the XR600 stem is longer than the XR350 stem. You may want to measure and see.

I have owned two '85 XR350s, one bought new, other bought with 150 miles on it in '90. They were both great bikes for their day, only major deficiency was the suspension, especially the forks. I fitted the one I bought new with White power 4054 USD forks and a White Power Super Adjuster rear shock, man what a difference. In '91, I put '91 XR600 forks on the other 350, this was also a major improvement, but not in the same league as the White Power suspension. I subsequently used the White Power units on a '91 XR600 and a '98 XR628, the 600 steering stems were the same as the 350, didn't need to change anything. Anyway, if you use XR600 forks, use the '91 or later cartridge units, they are way better than the older damper rod forks.
