I just got this 99WR400. its in great shape. Stock pipe. WR timing. I did the Taffy mod on the accelerator pump shaft per posts on this forum with .5sec duration .6mm gap. What Im trying to find is a good jetting setup for sea level both with and without the 'octopus' and maybe a link on how to remove all those hoses and move to the YZ setup if anyone has it bookmarked. So far I found theres a 172 main, 10mm float instead of the stock 9 and who knows what other mischief in there.
