rt 180 question

I see from past threads you seem to get stuff that others may not want anymore and make it yours good thing

its not my bike its my buddies im fixing it for him the idler gear dident have any clips holding it on so it was just sitting there so I had some off of a blaster I used and there is saw dust in the brake master cylinder so I have a blaster master cylinder on there for now
 
iv git another question the bike will only go into 1 2 3rd gear and it has no clutch when you start it up and try to go into 1st it pops the frontend up a lil and stalls the only thing I can think it can be is the acuator
