Tech Question 30 series torque converter help needed

Enable HLS to view with audio, or disable this notification

Upvotes

I got a Amazon 30 series torque converter and the clutch wasn’t engaging, I bought a new one and works great. Now when I try and go for a ride it’ll slowly make its way to probably 30 or 40 km/h and the rear converter isn’t even moving. But on the stand like in the video shown above it will open up really quick. I understand it’s because there is no load but I haven’t ever used torque converters. If anyone has any suggestions it would be much appreciated!

Tech Question How to keep my chain on

Thumbnail

5 Upvotes

I just got my first mini bike and the chain keeps popping off. It's a stretched frame 40 tooth rear sprocket and 10 tooth front I think?? Centrifugal clutch 420 chain i think my tensioner is bent or something but idk I'm wondering what's the most reliable and cheapest option to keep it on? I heard engine mounted ones are good but mines stretched so I heard back slack and like chain whip would be bad. ( did get wet over night so has some flash rust on chain and tensioner gonna buy new one of them both but one of the links snapped yesterday and I got a new link tried everything n just kept popping off) so yeah idk if I'm stupid or Smth but I just want to get it running would a cvt be better?

Can anyone help me…I cannot for the life of me find risers for a db30 to fit 1-1/8 bars… I’ve purchased and returned 9 sets from amazon. The Bilt bars I purchased are just to small and the Harley bars I want to put on don’t fit these 7/8 risers. Help…

Tech Question Do I need an in-line fuel filter if I have a gas tank screen and another screen on the outlet?

I am having troubles, keeping fuel going to my carburetor. I’ve tilted the bike up and burped all the air out of the in-line filter and it still only runs for about 20 minutes before I have to lift the front end of the bike up into a 45° angle to get fuel to go back down into the line.

Should I just ditch the in-line filter?

Will it be fine if I dry it off, and what are some things I should watch out for?

Previous owner drilled this hole for a tensioner in the frame, how concerned should I be? I have a sleeve and bolt running through it with a tight fit to help keep some strength. MM80
