First let me say the bike runs better and stronger then any other bike I have ridden. I put the 48 170 jet combo in and it took away all the popping. I have been reeding posts that say I should change the front tire and and lower the front forks for handling gains, how important are the changes for the bikes handling. And if I make the changes what tire should I go with and how much should I lower the forks? Any info would be greatly appreciated.
