Got it together and it actually drives pretty good it carried me up our yard without stalling,throttle response is great. Carb still needs fine tuning but for now I’m leaving as is so he can his surprise tomorrow!! Have video of it running. BC464A43-0304-463A-8479-20CD40CA65A7.MOV

Yes head was tightened in x form until I felt it was tight enough. for the oil line I’m gonna have to check that again as I don’t think it was connected prior to me buying it,could be the reason why the engine was covered in oil/dirt grime.. i removed the restrictors because some already missing and with all the reading I did they say the quad doesn’t have power to go up any hills in stock form etc and where we live we have hills of all sorts my yard has incline to it etc so I want it to go as best it could. when I originally purchased the bike muffler bolt and gasket missing etc. tomorrow I’m taking case off to look at the clutch and see what it looks like hopefully doesn’t need to be swapped out but if it does new shoes will be here day after Xmas hopefully earlier. i also ordered all stock parts with restrictors today if it runs bad etc so then I can just put them on in where they go,as it’s set for oem it restricts fuel to a very minimal amount etc

So with the time I had today after bringing kids to school,I stripped the bike for the 4th time and hopefully last.still need take exhaust and clutch cover off. but I tried derestricting the elbo to the head I could not get that spacer piece out so I just widened it up with a drill bit gonna have to clean that part good cuz of the shavings. took carb off and throttle cable and I realized I assembled the carb wrong.the needle was sitting on top of the white plastic piece..I’m an idiot but that’s what I get for having minimal time to tinker with this thing. But I did take out the first jet that piggybacks the other “one part of derestricting” so I think it’s destricted i also tightened down the head more as I don’t have a torque wrench so just got it good n tight with extra tightness haha. parts coming in by Friday I hope which are throttle cable,gasket set,carb rebuild kit for oem carb,a new fuel valve with just on/off/res. And a new cdi box. Also a set of oil seals but hoping I don’t need to get that far. i will be stumped if none of this works! One other question is how could I tell if the oil injection pump is working?

These from what I understand these don’t have belts? Video of bike running after was all put together with wheels off ground 4DBF5978-EDCD-4F88-BFA6-33009C9944E1.MOV

I changed oil the day I got the machine that was first thing I did I want to run it with this oil in it for a bit to help flush it out then do another oil change.. im gonna take case off today and take a look at everything without unbolting it so hopefully I can see if it’s good or bad like that.

Ok so before I go taking the case off,do I need drain oil? No big deal if have to but would prefer to get carb set correctly then run it a bit since the oil has never once been change,and would like to do a good flush,was hoping to have it done by Christmas but all parts won’t be in by then.

The quad is oil injected no mixing needed, quad has power with wheels off the ground,once driving it moves but as soon as there’s any sort of incline it completely dies. i have to replace gaskets for muffler and carb intake area where it connects to the head,so after I strip it all down for the 3rd time I’m gonna remove all restrictors and then go from there. i ordered new clutch shoes not sure if I need them or not but gonna attempt to take the case apart and see what everything looks like. I don’t really want to mess with the clutch as I’m not sure of what I’m getting myself into. if none of this stuff works I’m just gonna throw the bike off a cliff and buy a new one when I have the money to do so

Did compression check today I’m getting right about 90psi is this ok for a 50cc. im assuming nobody actually uses this sight since no one helps.

Yeah I got it all back together but just dies with any weight on it on slight uphill grade.and doesn’t have a smooth sound sound to it. might just rip it all down take out all remaining restrictors,and take spark arrestor out. I just ordered a new clutch and gasket set and throttle cable also a carb rebuild kit for original carb. i really don’t know what else to do with this thing to get it running correctly. also when I take clutch cover off will I need drain oil first?

Hey everyone,been dealing with quads since I was a kid,now I have a son who loves my raptor 700 and had gotten him an electric power wheel quad but it didn’t cut it for him.so for his birthday “xmas eve” I picked up a used 2002 quadmaster 50 for 500 bucks. It started and moved but needed work.. got it home drove it for a few feet and it started bogging down and would shut off. so I stripped quad down to the frame cleaned it up as best I could without removing motor from frame. replaced top end new head piston rings etc cheap kit off eBay along with carb that will be here today.the filter that was on carb was degraded and soaked with gas. Also new cylinder doesn’t have vacuum line so how do I block that off without getting new petcock valve? tightened chain. guy said quad doesn’t take oil as it’s a closed case right then I knew the guy knew nothing about the machine. So I changed oil,was black and thick and just nasty like sludge. suspension in rear seems good but the fronts are very stiff,any way to adjust these or should I get a new set? also upon stripping everything down I noticed the exhaust restrictor was gone so without that do I need to update jets in new carb,old carb has original jets?? and also I’m new to cvt tranny so how would I know if it’s bad etc? sorry for all the questions just want to make this thing safe for my 5 year old knucklehead. added some photos of my current progress didn’t take any inbetween cleaning everything though please any info will be appreciated. i haven’t rebuilt a quad since 1999 when I had my blaster and my buddies had other 2 strokes I was the mechanic with no knowledge but always seemed to get things right!! also if you notice the old head looked chipped and damaged and I’m wondering if those chips made it into motor how would I go about finding them?i would think by now they would be chewed up? I did not strain oil that I drained but might do that later when the kids are sleeping and I have time to check it without kiddo seeing!
