It might be too big. How come no one ever utilizes the 212cc's red-headed stepchild, the 79cc 3 HP Predator?

I challenge thee, good sir. I have thrown down the gauntlet.

I have 2 of them, there is very little torque. Also for the extra 12 bucks why not use the 212.

Also last years build off winner used one.

Maybe when you build JOE own mini, you can use the 79cc. This is NACHO bike.

AND I have drove (driven?) ...TESTED an 80cc mini bike that belongs to a 300lb+ Latino with face tattoos. I decided that that engine would be cute on his skateboard.

"I have test Driven" I believe these are the words you were looking for!

Is the "impudent" about the suggestion for FR to weld the chamber?

You have to steal the smileys 1 at a time.
Click quote on his post and they come up.
then copy and paste into a word file and use at you leisure.



[EDIT]
Also Hellion I would have used "impetulant" in this case. Same point but less confusion with "impotent" remember we are dealing with the simple minded!

You guys are a trip... But just to clarify again - This is Nacho bike - it is Mine.

The only way I will throw in a puny engine in these minis again , would be just to get my son use to riding.
5hp and + all the way.

I do actually have a question related to the build though...

Can I just use the scrub brake as is? Metal scrub to rubber? or some kind of rubber to rubber?

I thought the had an aluminum pad. 'shrugs' I think the aluminum dissipates heat better.

I will say I am just guessing.

Mine does...but it's almost completely worn out...I'm not sure what I'm going to do about it.

This will never get old (bold for emphasis).

I was just wondering aloud about the 3hp Predator. I have read that ungoverned and "freed up", the 6.5 is like an 8hp and was wondering if the same was true for the smaller one.

Scrub brakes have always been metal to rubber. Rubber to rubber might not actually work or it may work better (shrugs)?

EDIT: "Impetulant" could work but you're adding more syllables (not always a good idea) and the fact that the word does not exist. So much for getting the upper hand.

I've seen lots of metal scrub brakes, but the thing is they suck in the rain or if you go through a puddle. I would not line it with rubber either, too much friction then. And lets face it who needs their rear tire starting on fire after a stop?

Like the old joke goes: "Doc, it hurts when I move my arm like this."

"Well, don't move your arm like that!"

Corvettes suck at rock crawling.

There's plenty of folks around here who would consider that a novel idea.

Now that the garage is clear, I decided to play with Joe minibike...



Pic 1 - predator placement, covers a half of the right side foot peg. No biggie.

Pic 2 - is a pic of the scrub brake. I fitted the smallest wheel I have ( 4.10x3.50-6) and the scrub brake impedes this the tire

Pic 3- Bye bye scrub brake...

Pic 4- I removed the handle bars and forks and it doesn't even use bearings The neck tube is a 9/16" ID and uses a 9/16" bolt - weird. The bottom hole in handle bar has/is worn larger, causing play and slop in steering. I will try to correct this maybe by welding and re-drilling or flanged bushings - I guess.

Flanged bushing...welds are hard to drill...and the hard metal might even cause wear faster.

Shorten the neck 1/2" top and bottom then weld on 1/2" length of 1 3/8" id Pipe. install 5/8 id bearings and a long 5/8 bolt.
Get some bronze bushings for the Flat metal on the forks.
I dunno just a thought. Something like that maybe, that installs bushings.

Nice ideas...

I did go ahead and bought 2 bronze bearings ( which won't be in until Friday), then I bought a fine thread bolt - instead of the course one that wiggled loose.

I like the though of welding a bearing holder size neck tube but that is a lot of work.

Someone also suggested I tack weld the nut to the bottom cross bracket and then just use the bolt.
The welded nut would take care of the slop.

Hopefully the flanged bronze bearings work.
