Launching From Dead Stop

[Wildkat]

Just my 2 cents

I may not be able to advise on the mechanics... but I can sure reply on the performance. The 81 has the 750 mod and I love it!

I get around 40+ mpg where I used to get around 35 - 38. These days, with fuel cost especially, it makes sense to have it. Sure I gave up some speed but the only time I really miss that is when fellow TeXSives are around who like to live a little...


I have the FJ for speed (when it's running) and I have the XS for cruising and since the 81 is used for that purpose, the 750 has really made a difference.
The mod has already paid for itself in fuel reduction and it seems to be holding up rather well.
Around the forum, there have been one or two cases where someone who did the mod found shavings, but there's been a time or two where the original 1100 final took a dump as well. These bikes are very individual I've noticed... Mine has characteristics that John's doesn't exhibit and his has some that mine doesn't show. So maybe the 750 mod works for some and not for others... works for me and if I get tired of it... it's a pretty easy switch back to the 1100 final drive.

Prove what claims? Seems to me that one can go either way.

Yamaha dropped the ratio in teh 11 so they could pick up a couple tenths and get the 'first in the 11's' claim to fame.

I'm not interested in running in the 11's so I don't need it geared like a truck.

The whole arguement is stupid. Some vehicles actually give you a choice of ratios right from the factory. You pick and choose your ratio by what you need the vehicle to do.

I'm running 3.73s in the Monte. Anyone want to argue that I should be running 4.10's? 4.11s? 3.90s? maybe 3.08s?

By the way, if anyone has a Ford 9" 31 spline center section laying around.....

I have a 1980 XS1100SG. The bike runs great. I can let out the clutch and take off easy or I can give her a little more gas and let the clutch out a little quicker and move off with no problem. It runs right up to 8000 rpm with no trouble in all gears. It's real reliable and feels quick. The question is why am I having difficulty getting the rear wheel to spin from a dead stop? If I dump the clutch at 2 to 3 thousand rpm, it kind of bogs down and the tire won't break loose. Even at 4000 rpm, pretty much the same situation. The rear tire is the stock size (Dunlop D404). Anybody have any suggestions, ideas? Thanks

PS Air pressure is 26 psi and tire has 1000 miles on it.

I guess I'm a candy ass cheap bastard. I seem to want to keep my tires as long as possible and don't feel the need to do a burn out.
Try standing on the ground (weight off of the bike) grip the front break with all your might, hope that your bike won't take flight.

Hmm? I'm a poet.

DAMN! Now I got-a look up another mod....be right back.
OK I'm back, all I can find is a final drive mod.
Please explain the 750 mod.

Thanks

Hi Van,

It IS the final drive mod which is being discussed; the 750 came with a sensible rear ratio for the job it was designed to do, But when the 1100 came along, they dropped the ratio (more revs per mile!) to gain better times in the Quarter mile to help the advertising out...........

The 750 bevel box swaps into the 11 with a couple of tweaks. It gives a more relaxed and economical ride, but doesn't help the drag-strip performance.........

There has been some "Spirited" debate about the benefits, but I guess that if the 750 has enough power to pull the ratio, the 1100 should manage!

My bike has no first gear, hi-ratio bevel, and happily does the odd donut, Although only once the tyre is shot!

Thanks for the quick reply.
Interesting info. At first I was simply after a cheap scoot to help with around town adventure and to help take the load off of the Goldwing. Now, after finding out about the mods (like the oil filter mod and this 750 mod) I'm thinking this bike could be an continuous ongoing bike project.
Man I thought I was a sick bastard with my Goldwing but I can see the Frankenstein coming out now and I haven't even got the XS11 yet. I should get it first week in Dec. Man, I'm a sick F***er.

Pull the other one

"I bought the XS as a TOURING bike. Mine is fully decked out, and I am looking at fuel economy, not wheelies or burnouts."

Hi Craz,
admit it. Just like me, you bought it because it was the most powerful bike you could find at a price you could afford to pay.

[Crazcnuk]

Actually, I traded my Shadow 1100 for a mobile home several years ago, and have been riding a 750 Virago. I think the Honda was the best vehicle I've ever owned. Put nearly 90,000kms on it and never had to fix anything other than my own stupid mistakes.

A friend of (Ryan) ours was looking for his first bike and another friend (Al) found the XS1100 for sale for $500. Al took me to look at it, and I told him that the XS looked like a good deal for the $500 (it wasn't but that's another story), but not for a new rider with 0 mechanical ability/experience.

The XS was definately a fixer upper and Ryan needed a turn-key bike.

I bought the XS (the rest of that story is covered in another post here) and suggested the Virago as a starter bike, but he didn't want to spend what I want for the Virago. Instead he found an 82 CB900C for $500 that is fine mechanically, just a little rough cosmetically.

Since then, the XS has become the 2nd most expensive bike I've ever owned, but is now showing some real promise.

Al was the XS lover. He had a couple back when they were brand new. I had never evenlooked at them.

Hi Van,

I know what you mean about there being a lot you can do to these. This is mine, half-way through getting put back together after painting. I bought it as a stock SG (Special).



If you want to see a heavily modded one, try a search for Mathh's turbo bike.........

Having trouble with your burn-outs? Maybe one of these Ladies can help.

burnout

You can do a burnout but it takes a little more rpm than 3-4K.

I've done it before (not recently mind you). You can rev to 6k rpm, stand on your toes to take the weight off the bike. Dump the clutch and sit pretty much at the same time and the bike will spin the back tire. It will give you an "S" pattern. At the top of "S" which is only about 20-30 feet you will be ready for 2nd gear. If you bang it good it will give you a wheelie from 6" up depending on your weight. It is a tremendous hole shot and while the other guys are still spinning you'll be half way down the track. My buddy had a 79 Standard and one afternoon with too much time on our hands we discovered the aforementioned method. Good Luck and be careful.

[HobbyMan]

IMHO Be careful what you do to your engine as well. I have seen plenty of videos of engines bursting into flames from continually running the engine at high rpms with no air cooling. Any oil on the engine may ignite. Not to mention the fact that intense heat may warp metal. I don't think anyone would be dumb enough to do this to an XS but you never know. I understand that some people burn out to warm up their tires at the track but it really isn't necessary for us. If you are just showing off, dump some soapy water on the ground.
