Now it's really running!!

I got a little anxious to actually ride my BSR, so I decided to build my own stool frame that would fit over the engine without having to do any mods to the motor for now. It is only supposed to be a temporary solution, I want to have a real... mass produced stool to keep with the tradition of a real BSR. Anyhow the one I made seems to be pretty sturdy, and it has allowed me to experience the true terror of riding 6.5 horses three feet off the pavement. :cheers:

Not too bad! Have to tried to ride a wheelie yet or ride it on the two side wheels?

josullivan... looks good man. I meant to mention this before. I had to jack my stool up 1" all the way around at the bottom to get everything to clear on the motor. Just looking at your pics I'm not sure if that will help in your case because it looks like you might have your motor sitting farther to the right ( pass side ) than I do. Just thought I'd throw that out there.

But hey .... that stool you made looks real good. Get it chromed and let'er ride... lol

I got a question for the rest of you guys that have built one of these insane machines... Does your barstool seat still swivel around, or did you secure it to keep it from spinning you off when you go round a corner? I left mine alone and was doing a test run when I locked up the brakes. The ass end of the bsr spun out, and the seat swiveled the opposite direction, nearly sending me to my death. Is the swivel action supposed to be part of the thrill of the ride, or can it be disabled and still adhere to the code of bsr construction??? :cheers:

Josullivan,

When I first started riding mine, I had the same problem when I was flying down my street and went into a corner. I was going to tack weld it solid, but then I got use to it and now I use the swivle to turn my body when I go into the turns.

I would just go for it! You will learn how to handle the bsr with the swivle, it makes it more interesting. :eek:

next time spray Armorall on the seat......handlebars....and your butt.....have someone ready with a video camera....send us the video....or better yet have your heirs post it for us to see how exciting your last few seconds of life was...just kidding!....I removed the swivel and lag screwed the seat back on...Its just physics...high center of gravity...twitchy steering...high speed....a dip in the street...a manhole cover...see my point....one too many variables in altering the balance that maintains stability....enjoy!

Yeah, My barstool had the swivel seat. I use conduit hangest to stop that insane ride.

I think there's alot of good advice to be had from visiting this forum. I've been able to solve most of my build problems because of this site, however, I don't think that Armor-All is going to do anything other than land me in the hospital... I've noticed while riding my stool that the cheap clutch i bought is always engaged. When i let off the brake, it just wants to run. I'd heard about oiling it or something like that. Is there a trick to preventing this unwanted motion?
Also, it may just be the clutch, But i've noticed that there's not a whole lot of power to the rears when i gas it. It just sorta ambles along for a few feet then gets going pretty good. Is a wheelie out of reach with just using a clutch? Do I need to get a torq a verter to get the maximum output from the motor? :gunsfirin

Josullivan,

I have an idea. How fast is your idle? I use a tork-a-verter and I needed to turn it down a bit because it was trying to creap on me.

I turned down the idle all the way down before I have slow throttle response when I hit the gas. It might not be a cheap clutch, just a high idle.

-------------
To answer you other question. What size engine are you using and what tooth count rear sprocket?

The problem with the lag could also be the clutch is over heated and can not grip. The same thing happens on car brakes if you stop them hard at high speeds to stop.

Mike,
I'm running the 6.5 Tecumseh Power Sport. My rear sprocket came from Barstool Racer Supply and it is a 40 tooth.The clutch is a 10 tooth Comet brand I got off ebay. Is there something to do with the tooth ratio? Do you have any further insight? Thanks!! John :cheers:

[Mike Bean]

Josullivan,

I run the same 40T sprocket as you do, the only thing different is a tork-a-verter with I believe a 10T drive sprocket.

You definitely have the power to pull wheelies, no doubt about it. I can only think of two things. Turn the idle down to where the clutch does not constantly try to creep this way the pads can cool down. Otherwise I think maybe the tork-a-verter has a much stronger grab that the clutch when hitting the gas.

The tork-a-verter mainly comes into play as you speed up. It sounds like you are looking at some type of clutch problem.

Let me know if you can get the idle worked out first.

:gunsfirin I got er all tore down and began painting. I decided to go with Rust-Oleum in order to get that "professional" look. Anyhow, I started with a couple coats of primer then put on a few coats of purple. Why the hell I chose purple, i'll never know. Maybe because my daughter likes purple so much?? Or that my girlfriend went to TCU...It looks pretty good though... I plan to put a couple coats of crystal clear enamel to finish it off. I plan to do some detail painting of other parts as I put it back together. Hopefully when it's done, I can get a video uploaded.

Depending on the clutch you have, you might be able to change the springs and get different engagement. The Noram shoe clutch that are used on some racing karts would be a good clutch for these machines. You can change springs for different engagments, use heavy or light shoes, even position the hub for gradual or soft or hard engagment. They're around $50.00 and you can order what tooth sprocket you want on it. The drum/sprocket is sold seperate also and you can have different drivers(sprocket). The smaller, or less teeth you have on the clutch will allow the engine to rev quicker. The larger or more teeth you put on the rear will allow more bottom end speed and quick starts(wheelies),

the less teeth you put on the rear, the more top speed you have. One way to figure your ratio is to devide the driver into the driven and that will give you a close ratio. Of course tire diameter comes into play also, but for what we are doing the above method works fine.
