change

engine in progress

Ok guys, now that I know what mini bike I have now I can get to the real question. I need some help with what to order to replace the existing torque converter with a new one.

Anyone know if it is possible to change a fitting like pictured below? I fitting that went up at a 90 degree angle would fit much better on my bike but I don't know if it's possible to change out and if so where can I get the fitting I want?

Looks like the OldMiniBikes forum got changed up a bit....not bad though, I kinda like it !:thumbsup: Or at least it did on my PC.

So I added an OldMiniBikes stage one kit to my Predator 212 (exhaust, intake and re-jet). After I changed out the jet I can't get the fuel to stop leaking from the egg shell cover on the float. Any suggestions? The round gasket is still there and the bolt only tightens so much, could it be I...

Ok, I've made up my mind on what minibikes I'm getting my sons for Christmas. I'm picking up one db30 in the morning after work. I have a stock predator in the box to put on it. I'm going to order the engine adapter for it and get the sprocket adapter for it and run a 53t on it with a tav. I...

It's funny how we go day to day working on our hobby and collecting enough projects that we will have to live to 200 before they are all done and suddenly your focus changes.Last weekend I found out that an old hydroplane racing buddy has serious colon cancer.In the 1960s he build with his dad...

I picked up a 1970-ish Hilltopper with the original Tec H50, it hadn't ran in a "few" years. I got a $20 Chinese carb for it but it would still "dance" against the governor. Tom suspected it was the points. So I got a couple NOS points sets and condensers. I pulled the flywheel, it looked...

ok so I have a 212cc predator with a jet kit from OldMiniBikes warehouse and an air filter from studz.... and it is running terrible for some reason! the only thing I did was change those 2 things. When I go full throttle it feels like something is holding it back... like not enough air or something. Can...

Planning to swap one of my 196cc Baha engine with a 212cc Predator. Will I have to change the clutch, or will the old one fit? Anything else I need to worry about? Thanks.

hey everyone. so i decided to dig out my old bike and get it going again. One of reasons i put it away was because it was so loud and had virtually no exhaust, so i decided to change it completely and hopefully make it quieter. Its a Tecumseh H60 this is what I have thus far: I wanted to...
