Good evening guys,
Just got finished with my build, and I was aiming for a goal of 20hp. I don't have a dyno, and just wanted to get a ballpark estimate on what you guys think this build is making.

So I’ve been searching all day for a replacement tire that takes 2.75/3.00-9” inner tubes.
The tire is labeled 120/50-9, but unable to find one anywhere. It’s a rear pocket bike rim from X1 pocket bike.
I have a large gash in the tire I would rather not patch, and get a replacement. Was...
I got some 52 lb valve springs on the way, and wanted to know an easy way to get them installed if there are anyways. I usually put the engine at TDC & put rope in the spark plug hole to hold the valves in place to the springs decompress. Not sure if that will work with the 52 lbs I might lose a...
Currently have my mini bike setup with a tav with a 7" driven, and was just curious if anyone has experience with the 7" vs 6" driven unit. Which one would get more top end? I would assume it would be the 6" driven since it is smaller, and would be a smaller final gear? Would appreciate any comments
How's it going OldMiniBikes readers,
I'm looking for a doodlebug rear rim, doodlebug brake rotor, and a 3 disc clutch preferably bully vortex etc, also looking for 1.2 or 1.3 billet roller rockers Let me know if you guys have anything.. Thank you
Anyone know the difference in size between these two belts? I have a tav 30 unit with a 7” driven cane with a 203589 belt, but it’s a bit tight. Wanted to get the bando Kevlar belt which is belt 203591.. Thanks OldMiniBikes
I have a chinese copy of a tav 2 with a 7" driven, and wanted to upgrade the torque converter belt. I believe the part number for the comet belt for the 7" driven is 203591.
I am specifically looking for a bando premium kevlar belt for the tav 2 copy, but am having a hard time locating any. On...
Decided to go from a shoe clutch to a torque converter so up for sale is a lightly used Hilliard inferno flame clutch. Asking $65 shipped with 11t/13t driver, and all necessary hardware to install including clutch bolt with lock washer.
The black springs that are currently installed in the...
How’s it going fellas,
Down to the last leg of the project, and that’s getting my chikuni 22mm tuned/jetted just right.I live in Colorado 5000-10,000 elevation when riding so keep that in mind as well.

Trying to re-jet my pilot jet on my knockoff vm22 mikuni carb, but having a hard time finding a pilot jet that looks the same as the knockoff. I already am using a genuine mikuni as the main jet with no problems. (Large round head)
After looking around on forums for a bit a couple of users are...
So I had the stock db30 throttle control on my modified doodlebug, and the twist grip twisted clean off (break at the white plastic)
I'm looking for a throttle control that can take abuse. Was looking into dirt bike throttle controls 7/8". Anyone have any recommendations for one? Seems like you...
I’m trying to figure out what size the bolt is for the predator 212cc gas tank - the one that holds it in place In the rear. It’s part #84 In the manual - hopefully someone can help
Hey guys,
recently noticed that my kill switch is not working on the predator 212cc engine itself.. I got into a little crash couple weeks ago, and I guess the ground ripped off then. My question is can I splice/crimp the wire, and run another wire to a ground? Not the best with wiring diagrams...

My forks are completely fried and I was looking into getting azusa front forks to replace my doodlebug forks. I measured it all and it seems like a direct drop in, but was just wondering what the community thinks is the best front forks for the doodlebug. There aren't too many direct drop ins...
Has anyone run a mcp rear hydraulic brake on a doodlebug or have any pictures of a person that has? I'm trying to run a mcp brake with the stock disc and re-weld a bracket, just wanted to brainstorm some ideas off other members on this forum that have done anything similar, thanks.
I ride my mini bike pretty hard and throw the chain twice in an hour of hard riding. Mostly street riding, but when I hit a bump in the road at full throttle it may throw the chain. I currently run a 12t clutch 59t split sprocket with the OldMiniBikes split sprocket adapter. I was thinking about either...
