hi, i have a 1992 tomos targa w/ a bi-turbo. once i hit the gas on it it just kinda sits there for a sec while the engine revs a little then it goes slow at first then faster. but on my friend's moped the second you hit the gas it jerks you forward. are my clutches bad? i have another clutch pack if they are but i dont wanna take it apart if it is good. thanks for the help.
