- First thing, Happy Holidays to everyone. I know this has been a rough year, and I hope everyone is doing well. In this video I replace a damaged Throttle Cable. I used the Yamaha OEM parts and was very happy with the results. I also show How I adjusted the carburetor at end of the video. Be sure to check out my channel for all my current and future videos on my sons PW50. Drop a like, and SUBSCRIBE. Its much appreciated.

Awesome videos! just picked up a 1993 PW50 for my daughter and I have a oil pump block off, single throttle cable, pod style air filter and throttle housing arriving shortly. Im glad you are doing the big bore kit as I too am contemplating that for my daughters bike due to the engine being a bit old and the previous air box being broken.
Ya I’m super excited. Just finished the boysen reed install that vid will be out soon. I’m waiting on exhaust parts. Going full fmf but they are not here. So didn’t want the top end just sitting there till I get those parts. Cheers glad you like the vids!
As always great vid, explanation,and narrating 👍
Thanks man. Glad you liked it! Can’t wait till I’m done this new mini series. Just finished the reeds. Vid will be up soon. Cheers. Happy holidays or as I would normally say merry Christmas.

Great video! Thanks for the information!
Glad it was helpful. Cheers!
Have a very niche question: having an issue with my 96 pw50 where the oil intake line (from the oil pump) connects to the side of the carburetor. I fully replaced the old carb and installed a new oil intake like hoping this would fix the issue but it hasn’t. The issue is that the little tube that feeds oil into the carb just keeps popping out and leaking whenever I ran it. I was able to make it so the tube was no longer able to pop out using some other smaller tubing (an unorthodox way that somehow worked and kept it from popping out) but then two stroke oil starting seeping through little areas in the carb itself, almost as if the bike is not accepting it and it’s back flowing out of every little crevice possible for some reason. The oil pump seems to be working fine so I’m stumped. Any ideas as to why this may be occurring and how I could fix? Thanks!
I just picked up a 2019. It revs high when it run mode. I thought maybe I had a choke that was stuck, but then I realized the slide was not dropping all way down bc the cable is too short. Glad I watched this video bc now I’m gonna try to take that coupler apart. That’s the only place I have left to get any more cable. I did remove the lock nut on the carb adjuster, so that gave me about an 1/8 inch more. I think I need another 1/8 inch for it to be right. Hoping it’s not seated in that coupler completely.
I would also make sure the slide is installed properly in the carb. It could be just sticking as well. Double check that!
The previous owner could also have installed the oil injection cable which would be shorter. I think the cables were like 30$ in total from a dealership or order oem parts from partzilla.
Could you clarify which side of the throttle cable that goes into the carburetor - which way it’s supposed to be positioned. There is a groove in the left slot(top of carb) and which way should it match up with the throttle cable insert. bottom or long groove facing towards the left side of the bike
I highly recommend drilling a hole with the hole saw or a step drill bit on top of your stock air box if you do not have a pod filter it will really wake it up. About 1inch is fine
I ended up with a filter pod and a new fmf exhaust in end. Did a vid on it. Worked awesome. Cheers!
Great video man
Thanks for the feedback. Glad to know I’m helping other people work on their bikes. Cheers!
@@bigair0176 yes sir.... it idles but dies out after so I was wondering which screws did what on thj carb. Should be good now
@@gabrielgalaxygh running good now?
@@bigair0176 yes sir running smooth. Thanks again
Right on! Glad to hear.
after 3days of messing with the POS i finnaly realised that motion pro cable is the wrong size and the cable to the carb is to short. so people who have problems with to high idle remove the air filter and check if the throttle falls down all the way. if not then you ither have a to short cable or have routed it wrong
Ya the aftermarket cables certainly cause lots of problems. The stock oem cable worked like a charm for me! Hope it was helpful!
I got the OEM parts and the cable is too short. 😡
How to tell if my pump is working? Can I used a gas mixture if not sure and leave the canister empty
Start the bike and pull the line that goes from the pump to carb. When it’s running it should weep out of the line. If you leave canister empty you definitely have to mix your gas in the gas tank. I ran 40:1 mixture.
Did you take out the little inline fuel filter and replace with the bigger one ?
I believe I did yes. I had a fuel filter from an aftermarket carb I think. Sorry it was so long ago now
Quick question: the tiny tube that runs from my PW50s oil pump and connects to the carb on the side was leaking and then falling out. I found a way to make it so the tube no longer falls out and stays in place, but then oil starts leaking from little crevices in the carb itself, almost like the bike isn’t accepting the two stroke oil or something. Any ideas why this may be happening?
Is it an aftermarket carb. If it is it could be that. Otherwise I would say give it a clean and maybe that will unblock a potential blocked passage. Oem would be much better then the aftermarket. You may have to replace it with a carb kit to help with the seals and all of that
@@bigair0176 the thing is I had an oem carb on it originally when the bike was sitting for a while and not running. It was all clogged so I took it apart, cleaned it thoroughly and put it back on. That’s when the issue started, but to be fair before I did that the bike wouldn’t even start. I then got a cheaper non oem carb thinking replacing the old carb would just be better and could fix the issue but it still remained. I even got a new oem tube as well and replaced the old one, still nothing.
Why is mine running full throttle when i start it up? I didnt ajust the screw on the carb yet could that be the issue?
Try backing out the idle screw first. If that doesn’t work, screw the top adjuster toward the throttle. You need to set the free play in the throttle. If the free play is good then it could be binding when you move the bars back and forth
@@bigair0176 does that mean when you say screw it towards the throttle, mean turn the thing the changes it towards it or the plylers
What is your fuel ratio? When you mix your gas?
40-1
@@bigair0176 how do you stop the bike from smoking? My bike smokes?
@@noahmoussa294 it’s a two stroke. It will smoke. The older and more worn the top end is the smokier it will get. Rebuilding the top end will certainly reduce smoke but it won’t be completely gone.
You only mention the one screw what's with the other screw
One is the idle screw and the other is the pilot screw
@bigair0176 yes I had to rebuild it I found that out when I opened it. Thanks.
adjusting the idle screw doesn't change anything for me either
Should fix that back wheel it looks bent. 😱
Ya it was on the list. But the boys have out grown that bike and it’s now been sold. Cheers!
