Oh gawd not a 99!!!!
Ok I'm just giving you a hard time. Nice looking bike. I like the old style bikes. I think they were built a little better. Some may argue but all the old ones I've seen have better crappy welds and such. I like the fork leg drains that were removed on later models. I also like the simpler slide carb vs the cv on the newer ones.
If I were to pick one thing to check I would say check the cam chain adjuster. Might I add that any new bike I would comb over and tune up. Check chain and tires. Change oil, adjust valves, clean air filter, lube swing arm pivot,ect. A shop manual is a must have. Have fun
