What is happening with your bike? Symptoms, etc... Post that as a question and I am sure you will get some responses on things to check.
do you h ave a friend who is a competent mechanic, or at least knowledgeable?
Your motor needs compression, air, fuel and spark to run. motors are very simple. update this with some symptoms or send a private message to me and I will give you some things to check before you pay a shop rate.
Although there is a variety of mechanics, your BEST bet is to take it to a dealer (provided they will work on your scoot--Harley won't work on a couple of mine so I have to do it). They are the experts on that machine. They will usually charge an hour of labor to diagnose the problem. When they finish, if they say you need (insert part here), and they think that will fix it, tell them, if it doesn't, then you are not paying for it. Remember, they are the experts.
A few years back, I took an old chevy S-10 to the dealer. They said "we think its the fuel pump" I said replace it, but if it doesn't cure the problem, I am not paying for it. you are mr. goodwrench and you don't get to guess on my dime. They replaced it, it didn't work, and I didn't pay for it. speak to the manager if you have to.
