The gen1 frames have a crossmember up between frame rails up near tank bolt to house the CPU and other crap, unlike most all other later model aluminum frame CR's and CRF's. Only way tank will fit is to cut the bottom front section and mold on new flate L plastic piece so tank will slide up and bolt on OR have a aluminum tank built. I'm doing the GEN3 frame conversion this week thank the lord.
Doing the actual gen3 frame swap is what I'd recommend for any gen1 guys. You can try to just buy newer plastics and fit them but you'll find there's no way to install them without having a terrible hack-job final product, or spending a ton of extra $$$ for a tank and subframe mods. Again, at that point you still have a gen1 bike with crappy fitting plastics. I've found a COMPLETE Gen3 bike ready to go for $500 with EVERYTHING. All I need from my 98 is the motor and wheels.
The real kicker is after I sell my 98 chassis without motor and wheels, revolutionizing my bike into a gen3 with factory connection suspension will have cost me almost NOTHING. My point is, if you really really want to do something like this, do it the right way. Don't just drill random holes in newer plastic and ziptie crap on. It's just plain horrid.

Well many many folks that have owned a 92-01 motor and then a 02-07 realize that the power delivery is poop. It is ALL top end, sort of like the 85cc. Bottom end power is absent like an electric scooter lol But it's different strokes for different folks. That is the best saying for MX'ers if you get it lol This is not presented as fact, of course, just my personal opinion and observations. It's simply because they were case reed induction motors and a few other small things like added electronics (reducing reliability) The 92-01 mechanical power valve motors + gen3 frame = secks. My 98 combined with that pwk has been beyond incredible. The gen3 is known and loved for it's revolutionized handling (frame) and suspension. Aside from that, building a bike is a hell of alot of fun for guys that enjoy wrenching/maintenance.
But I totally agree with you. I ordered newer plastics to convert on my 98. gen4 CRF plastics I could have done perfect, but I wanted gen5 and there was no possible way. The frame conversion is honestly just the way to go with all the trouble, unless you just don't care about screwing the new plastics on or whatever.
