    Manco Thunderbird disc brake mod

    I'd like to see something like that as well. The scrub brake sucks...especially when it's wet outside. Might as well not have any brakes. But you can get a clutch band brake kit from OldMiniBikes warehouse for like $50. That's probably what I will do in the future when i can get mine to stop throwing...

    Manco Thunderbird build

    You really should sell them Dr. Shop Teacher, I have the fabrication skills but I just don't feel like doing it right now. I know I will have to very soon though. Sent from my SAMSUNG-SM-N910A using Tapatalk

    Manco Thunderbird build

    I wish it were that easy with the chain. the clutch chain and sprocket are brand new. Now I didn't think about torque flex, but I don't think that is the issue. My best guess, and I've been at work all day to ponder this; and either the motor is vibrating backwards and giving the chain too...

    Manco Thunderbird build

    I'll upload pics later if I get time, but I finally finished the mini bike yesterday. It's scary fast, but the problem is that it's idling super high and it engages the clutch as soon as I start it up. And it keeps throwing the chain. From what I can see, it looks like it's aligned perfectly...

    Manco thunderbird torque converter install

    I thought about that, but then I would have to get an aftermarket exhaust an possibly relocate the tank. So I'll just save the TAV for my next mini build. I really want to get one of those ken bar whirlwind bikes. I missed out on one a little over a month ago. A guy was selling a complete...

    Manco thunderbird torque converter install

    Yeah, I scrapped the TAV idea after I kept trying to make it work without ditching the scrub brake. And unless I cut into the backplate, which I won't do because it's already a cheap China made part then it's still not going to work for me. So I just went to my local farm supply store and got...

    The Mikuni v. Chikuni comparison

    Thank you for the good info. I had no clue that they had knockoffs of that carb.

    Manco thunderbird torque converter install

    I'm so pissed that I can't even think straight. Does anyone have any pics of how you modified the TC to fit the predator. I don't even have the tools I need to modify this piece of shit.

    Oil

    Well I'll probably just run conventional 10w-30 then. Sent from my SAMSUNG-SM-N910A using Tapatalk

    Oil

    I know the manual for the predator says to use 5w-30 or 10w-30, but is it OK to use synthetic oil? Or should I just run conventional.

    Thanks. I think they look way better. And it makes for a better riding position. I'm going to have to extend the foot pegs because the predator is too big for the frame. Sent from my SAMSUNG-SM-N910A using Tapatalk

    Sprocket mounting holes not lining up.

    That's exactly what i'm going to do for my next mini bike build. Good idea.

    Sprocket mounting holes not lining up.

    just before i saw your post i thought the same thing. The bore of the hole is the same. All i need to do is use my old sprocket as the template then drill 'em and be happy. Lol.

    Sprocket mounting holes not lining up.

    I know what you're talking about as far as the sprocket shifting under torque, but this is far from that. every hole is just under a 1/4 inch off.

    Sprocket mounting holes not lining up.

    I don't know who the manufacturer is, but I know that none of the holes line up which means extra work for me. It's not hard to drill the holes larger, but I was hoping to just bolt it up and go.

    Sprocket mounting holes not lining up.

    So I got my 60 tooth sprocket in th mail from OldMiniBikes warehouse, and all of the holes are off just enough that none of the holes line up. I'll probably end up drilling out the holes larger to fit. Has anyone else had this problem with sprockets from OldMiniBikes? I'm kinda pissed because now I have to do...

    What fuel do you use?

    I'll have to look into that AV fuel or some fuel stbilizer before I start mine up for the first time. Sent from my SAMSUNG-SM-N910A using Tapatalk

    You would be correct sir. I wouldn't settle for anything less than a hemi. Sent from my SAMSUNG-SM-N910A using Tapatalk
