I got my used road legal wr400 99 two weeks ago. I spent my first free time (today) riding it on road. The bike is not as torkey as the 650 due to the difference is crankshaft weight and displacement probably. However, power is wonderfull and I'm falling in love with that bike. This bike is a lot lighter and crisper on power and control, couldn't go back to a 650l. Sure the seat is like rock but after an hour on-road it is less painfull than the 650l. The 650l had an hollow place on the seat an I was always fightting to put my ass outside than too-soft area. The seat of the wr is a lot harder but my ass is not always wanting to go in an hole spot!!! Easy to start bike even if the procedure is not as fast as a start button. Next step is to install the complete megamax I got from Clark, switch to yz timing and rejet. I'll post the result here for sure.
