Hey guys, I wanted some input on the xr400. I currently have a 1984 xr350r, it will easily pull the front off the ground in the first three gears without hesitation. I've been having the itch to get something more up to date. Yesterday I went out ot look at a 2001 xr400r, it had only been ridden three times, completely stock. I was really disappointed after taking it out for a spin, it didn't have any of the pep that my 350 has. Will after market modifications really wake it up or is it a waste of time?
