someone else already has the patent. good luck getting any traction on it sitting on the tank. wheelie machines were made for people who don't know how to ride motorcycles as an attraction, no matter what it will never have the same response as when it's not on the machine, so you won't gain anything in muscle memory which is 90% of the skill you need to stunt ride.
Well, first of all it wasn't hating. It's constructive criticism from personal experience. Yes, I'm a "real" stunt rider. No, I've never taken any falls to my head and I rarely even drop my bike. Yes, it would be a good attraction for bike nights, but it's not a useful training tool. There almost always needs to be someone to help the bike up because of the lack of traction.Originally Posted by PROFLYER

It didn't read that way. Anyway, maybe he could devise a system in the supports that would pull the axle down onto the rollers...

What is the point? Does this machine teach side to side balance or correct posture or throttle response? No. It's an attraction not a training device.
Do you have a point beyond bickering with someone who knows what it takes to ride a wheelie?
It does look like it'd be fun, just won't be very good for real world practice is all. I'm sure there will be a lot of people lined up to try it.

I wasn't questioning his skills, I was questioning his negativity toward an apparatus that looks like a good time, it looks like the guy has put some hard work into it and I can appreciate hard work. And for the record, I can ride a wheelie.[/quote]
He didnt say anything about you not being able to ride a "wheelie"
So when your bike is all mounted up on the machine you can move the axle down 3"? Just tryin to figure out how that would work cause i would think that you could only put a downward pressure on it only so much. Maybe if you took all the tire pressure out so its allmost flat then bolting it down then airing it back up again so there alot of pressure between the rear tire and rollers? Yes no? i dunoo......

Public forum moron, Do you usually come on a forum and make an ass of yourself within 10 posts?
Rhetorical, no need to respond.
Pretty fuckin ironic you talk about e-thugin'
Grow the fuck up
thats why he added the weights to the rollers, this will give drag equal to the weight of the bike so that its like the bike is free on the road and you will have to control throttle the same as if you were really riding.
and you did it!
the rest of us were just thinking it.

I know what "for the record" means but it was still retarded.
Ding ding ding! We have a winner! lol.
So here was my day.
Ok, so loading the bike to the trailer is easy breezy, but definitely a 2 person job. From the there, I got the bike on the springboard / ramp, and jacked the ramp up into position. Worked nice since the ramp becomes elevated once the shocks are in place, it helped the bike get onto the dyno nice and easy. 1 person lifts, the other aligns the bricks, and slid into position like a bolt action rifle.
Did some fine tuning adjustments to make sure I was level, and slipped the quick release pins with the downward adjuster set screw in place. This turned out to be a very convenient and easy thing to do. Adjusted the downward pressure on the tire, and locked it in place with the 3/4" bolt from below.
Got the bike powered up, and took the machine to my limiter in 6th... 130mph after various tugs and brake checks. Noticed as I was accelerating hard that I was getting some slipping.
After going over a few more things on the bike like tightening the preload and compression damping on the rear, took the bike out to where I could be loud and uninterupted and gave it some tugs.
Here's what I found out.
Even after the tire was all warm and gummy, If I throttled up hard, or slipped the clutch, I'd get very little lift, and tons of tire spin. So shut it down, and adjusted for even more down pressure on the tire. Still no dice.
The rear drum spun up fine, but the front drum connected to the pully / fly wheel was having a hard time getting up to speed. So, decided to experiment, and took off the cover, and unhooked the pully belts from the fly wheel. Tested it again. This time the tire was able to stay hooked up, but had too little mass to lift the front more than a couple of inches at WOT.
So, reconnected the fly wheel, increased the down force on the tire, and tightened the belts more that I had initially. Got no slipping from the pully, but still didn't have enough traction on the drum. But by tightening the pully, and increasing the down pressure on the tire, was able to get it to come up about 2 or so feet slipping the clutch to WOT.
So, not the news I wanted to give every one lol. But it's where I'm at. As far as the rest of my design, and mechanical bits... the system is sick. Super strong, and I have very few wants.
I'll be calling my machinist tomorrow, and see if he's able to do the metal spit coat (looks like 60 grit sand paper) on the roller. If he can't I'll keep shopping around, as I think this is going to be the best solution.
The dyno as it is now, has some vertical lines across the drum, and all in all is really smooth. No finish to speak of.
If I run into a hitch trying to get the drum coated with something that works like sand paper, but metal and more durable... I'll see if my machinist can put some horizontal etching on the drum and get me some traction.
Well, I could go on for ages about all this.. but this is where I'm at. Would have loved if it worked flawless on the first try, but I'm not going to let a little thing like a wheelie machine not being able to do wheelies get me down. lol.
Here's a couple pics of the current progress.

Lookin good. I was going to say something about getting some kind of grip tape for the roller, but I figured you had it covered.
