Another bike with a transmission issue....

[7911special]

Since I have a few things I need to get done and some time where I can't drive the bike I figured Iw ould get a few things done on it.

So I have the issue of popping out of first gear usually once the bike hits it's curve around 3500rpm and then any time you try to accel hard. This is only in first and it pops in and out but has never stayed out.

Am I looking at needing to do the dremel mod or is there an upgrade gearset and parts available? This bike has already had the tranny totally rebuilt from the PO, my dad. He informed me the bike has been well tested and capable of lighting up the tire through all the gears. That was about 15k miles ago though the last time he rode it.

I would like to just ride it this year, but it funs to accel off the line hard and I just can't do that in its state now.

gears

Bikebandit.com has those gears. You could also re-furbish those gears yourself. The 1st. wheel gear is difficult to re-surface, but it can be done. New gears are about $100 apiece. Your call.

Each gear is about 20 bucks cheaper at this site:

Yamaha Parts

1st gear 98.12
2nd gear 95.94

(These gears are 118 bucks and change at bike bandit)

If first gear is slipping, you'll need to replace first and fourth gear.

Hey 7911Special,

I posted that Dremmel Fix tech tip/pictorial a few years ago. Ken Talbot had posted one before it, using and recommending the use of the finer diamond bits on a die grinder. If you have a compressor, die grinder, you can get the bits from Harbor freight or Northern/Southern Tool for fairl cheap, and they will grind away much quicker/better than the Dremmel, and they have smaller bits that will work better/easier on the 1st gear slots!

If you've only been clicking on the tech tip links in the left hand yellow column, you've not seen many of the new tips that have been posted, but not linked in the left column, just scroll down from the main forum page, and you'll find them!

While you're in there, IF 1st is already going, might as well do 2nd at the same time, save you a trip back in later/sooner!

If money is no object, the new gears that are properly undercut are available, but if you are frugal, doing the dremmel/die grinder will do the trick most economically!

Just for what it's worth, my opinion is that the larger red Dremmel sandstone bits work much better than the carbide die grinders for the slots especially. I have done them both ways, and I found that when I wanted to get really particular and using a micrometer to match all the grinds, in those rounded slots the dogs fit into, the bigger grinding tip would hit on the entire bottom of the slot making a much cleaner, rounder, measurable grind. The smaller die grinder tip just can't make that smooth and perfect mating surface. The die grinder did seem to work better on the dogs though. There is a carbide die grinder tip made for dremel also.

So... just one person's opinion. Take it for what it's worth to you.

Have you guys found that simply replacing the gear pretty much solves the problem? My XS1100SH has that dreaded second gear issue and I haven't really gotten into it yet as I have been putting all my time in on my SG first.

Rather than using the SH for parts, I am restoring that as well so my brothers, father, son, or friends can ride along once I get it running safely.

P.S. In no way would anyone confuse me with a qualified mechanic but I am learning as I go.

Hey Don,
The new gears available from Yamaha are back cut so they are already "fixed." It's a more expensive option but, if you don't want to mess with grinding your own gears (so to speak) you can install the new ones and be done with it.

hi Don,

There is no real way to tell what the bike will need until you get in there; If the previous owner tried to hold the gear in with his toe as it tried to jump out, it will certainly need a selector fork as well..........

The second gear will also need the washer moved; I have heard of some being fixed by only that!

Thanks for the info guys.
