chain drive mod

Worthless = no value whatsoever

Worth less = not as much value as compared to another object

Thanks

Thanks Phil, I said and ment "worth less" then other bikes that have a chain and mods, even with the chain and mods on an XS. I love my XS1100SF, it means a lot to me, just not a lot to others I wish I could get back the $$ invested without even considering the hours I put in, A true labor of love

Doubtful....are we bragging or just trying rub elbows again. You make a statement like these x's are worthless without thinking about all the people who are on this site who own one without regards that it might be a bit insulting or hurtful in the process....and have the audacity to say we are wasting our money with these kind of mods when we could just go out and BUY a bike with all these features and still try act humble in the same sentence. This site is riddled with modifications, and not all of them are for making a poor design better, some are merely for personalization. Some talk about modifications are just talk, and will never see the light of day on some peoples bike, mine as well, its just talk, that's a forum. If "OEM" is more than just a moniker, please don't respond to my threads involving modifications. I apologize to everyone else on this site if I've taken my thread in an awkward direction...but I thought it was a thread on a "chain conversion", not a "why waste your money on a worthless bike thread"

I'm not sure you how you took what he said as a slight, but he's saying that the cost of the mod relative to the value of the bike is very high, so not many people are going to give it a try. And, probably, he's right. You are the only person to say anything about your bike being worthless.

What the guy drives has nothing to do with any of this.

I have thought about the chain drive mod, but to me it's not worth it. It adds very little, costs a lot, and to me does not provide enough benefit to be worth it. If I was spraying or boosted and needed the traction of a wide tire, maybe.

That said, it LOOKS really cool, so more power to whoever wants to put one on

Thanks guys

Hey Old Skool has put me in my place. I am not rich. I have a few things left to sell to care for my family. Used my 401k to help my mom keep her house, spent the rest of what I had to take care of her and my brother who has had two heart attacks, the next will be his last. All I have left is a 1998 BMW740IL, yours for $4,000.00 OBO, a 97 Jaguar XK8, everything has been fixes but could use paint $8,000.00. And my beloved XS1100SF $2,500.00 less then half what I have in it not counting the hours.This is all I have left and good stuff for any member to own, Thanks, and God bless

No need to defend yourself OEM. Life is not the same for every member on here. I knew when you said worth less, exactly what you meant. I look at a bike and I decide if I would spend the time and money necessary to make it live. If it would be smarter to make it a parts bike then it becomes one. By smarter I mean what it costs me to fix it. I have quite a few that will never see the road again, but the parts I glean will make others live. I am more an oem type guy than a whole new bike guy such as what Math does with his bikes, but hey each to his own.
Not, that I do not admire their abilities and skills and pure craftsmanship they show us. I think what they do is something that Yamaha should be looking at for the future. That said I do not think I have the money nor the skills to make an old XS able to battle a Hyabusa, let alone the interest.
Simply put, I do not care if you are really Bill Gates in disguise. You are a contributing member of the forum and that is good enough for me. I know that sometimes we feel that we must justify our lifestyles to feel we fit in. I am a concrete mixer driver. I have a couple of 2005 cars and a 1979 truck. Who the hell cares! The passion we feel and the comraderie we get from this site is what counts.

I said and mint "worth less"

Then you have my apology, Never meant to cause all this ruckus over something as simple as a misquote, not making excuses for my actions, but maybe just a little too much on my mind as of late, and you just became the target of my frustration. Sincere apologies. I'm going to take a brake from the forum for a while, need to get my head right with my personal life. Thanks to all who have helped.

Just to be clear

I would love an easy cheap way to run a chain on mine, for the most part to be able to try different sprockets for different trips, testing MPG and moving the nasty rattel to different RPM's If anyone felt I was putting down thier bike, a sincere apology. I love mine and know you guys love your too The only reason it is for sale, like all my stuff is for sale, is because I love feeding my family more then I love my stuff. Hope everyone haveing a tough time also, gets through it and comes out on top

cost vs hp

with a drive shaft you loose %15 of hp with every 90 degree turn and i'm not sure how much but there's a percentage loss with every foot of drive shaft also. if your looking for peak horsepower it is possible to do the conversion a friend of mine did it to his drag xs due to it had so much torque it would bend the drive shaft he said he just replaced the middle gear with a sprocket gear.

[cywelchjr]

While the loss of horsepower is indeed there, having ridden both shaft and chain driven bikes, I prefer the longer maint interval of the shaft drive, and since I'm NOT a canyon carver, I don't care too much about the loss to the drive shaft. I do however enjoy not having oil from the chain being slung all over the place.

[trdriver71]

I am with you on the shaft drive cy and like the amount of maintenance needed for the shaft vs the chain.

[XS1100_OEM4ME]

I would love to see some data on that, 15% per 90deg. turn, don't think so, and lose of hp due to driveshaft lenth Where do you get this stuff

I did some "worthless" net searches , found references to the 15% rule, but it was talking about power losses over the entire transmission from engine to wheels. Some more realistic values of 6-10% for hypoid differential gears from an SAE.org tech article source were quoted/found. I was getting sleepy and so stopped trying to find info on power loss via drive shaft length. I remember being told many decades ago that you loose horsepower if you lengthen the driveshaft!? So..not sure how much of this is anecdotal vs. based on any factual data??

But with our bike we have TWO 90 degree turns, 1 at the middle drive and then again at the final drive, so a theoretical loss of 12 to 20% due to the 90 degree turns looks more probable.

The middle drive conversion shown above would allow for a larger front sprocket, but as mentioned, requires a fairly wide rear wheel/rim due to the outward middle drive sprocket placement, vs. other techiques that place the front sprocket more inward but closer to the engine case which limits sprocket size to 13-14T! Not sure how much of an offset you could place on the rear sprocket for a narrower rear rim and still be in line with the outside sprocket??

The word confusion reminds me of a joke....newly widowed older woman interviewing new male companion prospects. Discussion of SEX gets a reply from fellow of "Infrequently" and she asks....is that 1 or 2 words!

Oh well, time for bed! Goodnight.

Cool

Thats Cool Someone said sometime that there might be a drop on HP with a driveshaft Can't find anything to prove it, I think it might be so, don't know if it is more or less then the drop in HP useing a chain drive Got to be something writen somewhere. I am sure that chain thing is better, don't know what Yamaha was thinking

Humor

Hearing all this bickering reminds me we need more humor here. When I was a teenager I rode dirt bikes hard and fast and when we do this there are learning opportunities. One lesson for me was the vulnerability of the chain when a bungee strap came loose and fell into the chain when I was wide open across a cow pasture. For some time my friends and family offered this little line and I offer it now so all can smile and appreciate the security of shaft drive.

He was going down the road making 90 miles and hour when the chain on his motorcycle broke. He was found in the grass with a sprocket up his @&& and strangled to death by a spoke.

Bless all here threw the new year as to many often have far more difficulties than we deserve to deal with.
