San Andreas PC mission help

OK, i'm stuck on this big smoke level where you go into this mall, protect big smoke from these guys, exit the mall, get on a motorcycle. The thing is, the damn motorcycle keeps blowing up in this cutscene for no reason! And also, there's this mission where you have to win in this race- are there any ways I can get rid of the other cars by cheating like in Vice City or will I have to race without cheating coz I'm a noob and racing games. Thanks ;)

That's odd, I play the PC version too and I never have any problem on that Big Smoke mission.
About the racing part, try finding some cheat for this game that might help you, I remember there's this one cheat that makes other cars flying, might help you in the race.

The racing missions are easy, just give as much speed as you can and break hard before every curve.

oh, i figured out what was wrong with big smoke- i did the health/car repair/money cheat on the bike and instead of getting it in better condition, it exploded lol. guess the makers of this game would've got a laugh out of that.
