Thanks for the reply. For a 196 c/c, the engine pulls very hard. The chain driven torque converted really does its job.

My Heathkit Hilltopper needed to have its 212 clone engine moved forward 1/2". I already had it on a riser to allow a proper alignment with the chain torque converter. I found on TEMU (...

Thank you for the reply.

It looks as though this muffler can be stuffed with pot scrubbers? Anyone here tried this muffler...

I bet if you stuff this muffler with pot-scrubbers it would make a nice low back pressure quite muffler! (posted in odd-ball minie's)

I checked out the mini today, only to find that I had "bummed" the headlight switch on. Battery pack DOA. There are erasers on pencils for a reason. I removed the battery pack and installed a remote power ON/OFF switch on the pack to prevent this from happening again. A waterproof switch boot...

I ended up, four years ago, using an aftermarket carbon steel axle that was too long and turned it down to the correct length.

It was fun to be sure. Next time will be to take the members back to the "5 Hills Of Death." A really fun ride with fewer rocks and boulders.

Here is part two. Lots of rocks and creek bed.

I went out today for a ride in the Lower Coyote Canyon on my Hilltopper. The weather was nice and other than one Mountain Biker, there was no one on the trails. The mini performed well never missing a beat other than the engine did not like my idle setting at 7,500 feet. Not a big deal, as I...

Interesting "lever" steering that move the front wheels and not lock the brakes like others do to steer.

Nice ride! Some wing-nut painted mine black. The original gold paint underneath looks to be in great shape. My bike was just a stripped frame when I found it in CA, at a minibike meet. It took quite awhile to locate the needed parts. I tried an original 5 HP engine but it was wimpy at my...

I just ran a dB level test with he repaired, and pot scrubber filled muffler. Here are the results. I do not have the before-n-after readings, but it is very noticeable. Engine at idle: Name: hilltoper idle Duration: 00:22 Maximum: 89.7 dB Average: 73.8 dB Minimum: 63.0 dB Noise Level...

Here ya go: Several of the sausage type mufflers have the exit spot welded to the center perforated pipe. If you drill out these spot welds (3 or 4) the two main sections will pull apart. A good twisting action will help. You then stuff in the pot scrubber pad around the center pipe. Slide the...

The stainless steel wool Chore Boy is a pot scrubber. Heavy duty and high temp. I've used it in other vehicles with no issues and no sparks. When I ride in the forest, I have a spark arresting filter on the mini bike, I can swap from bike to bike. Park Rangers like this device.
