run

A little background... it's several years old and always ran like a champ I just let it sit for 6 months like an idiot. Life got in the way. So last week I drained the tank, removed the carb, cleaned it out, changed the oil, and put some "Mechanic in a bottle" in to the tank. After all of...

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...

I just want to hear some experiences with high gear ratio and the other factors that go into play along with them such as: Weight of mini-bike (or go kart) and operator combined. Gear ratio. Size of tires. estimated top speed estimated time to get to top speed. `My personal experienced...

I'm trying to get the original HS40 from my Trail Tramp running but I can't get it to do anything for the life of me. Back in the fall my dad and I tried to get it running for the first time. After adjusting the points it ran roughly for a little bit till it sheared the flywheel key because we...

I've adjusted the idle screw and it helps a little but not enough. When I switch from start to run the back tire starts spinning fast and engine powers up without even twisting the throttle. What's up???

So does everyone have to have a video at the end of there build ? If so does it have to be just a run video of the engine running ? Or a ride video ?:scooter:

It's a Coleman CT200U, only mods I have made is to the governor and throttle stop. It's 212cc and I know it has enough power for the snow(talking 4-6 inches, we got 20 inches but I've made decent paths yet I have ZERO TRACTION), I'm just not sure where to start to allow more traction. What's the...

I'm trying to get the H25 on my Rupp Chopper running before I proceed with my build and not matter what I try it will not run off idle. It will sit there and idle all day long but the second you give it any throttle it start to pop and sputter like it's flooding and will not come out of it. If I...

The December 2015 Mini Bike of the Month is CarplayLB's "Home Run" 1960s Quarter Horse

I bought this carb off ebay for cheap money. The bore is about .625 which is a little bigger than stock. With 1.3 ratio rockers, 14cc head, and a bp2 cam with 22lb springs. Will it run good? Will it just flood the cylinder idling? I heard thats what the Tillotson carbs do.

I changed the points and the condenser, new plug,cleaned the carb, valves seam good. Starts off starts off starting fluid but after that nothing. I am really getting sick of these Tecumseh engines. Any ideas? Maybe timing?

Is this one of you guys??? Video: Police chase man on minibike into Pontiac home | News - Home

So I dug out my Db 30 + 196cc that I hadn't ridden in a year or so, but it had sat out in the weather that whole time. I cleaned the carb as best I could, and put it back together. I could get it to run for a few seconds but it would putter out. Figured just need to adjust the carb, so I found...

Does any one run the tillotson carb and are they worth 120$?
