Help with 1st gear problem on 81 S

[dadio917]

Hi,
My son bought this bike last year and quickly learned that it has a 1st geer problem. It "stutters" badly like it's tyring to pop out of gear or something like that.

I've perused the site, which is really great, but i have some question that i haven't found yet:

1) what does the dremmel tool fix fix? I mean, what is going wrong that polishing with a dremel tool fixes?

2) do the symptoms i describe sound like the dremmel tool fix will solve the problem, or should we order some parts?

3) If the answer to 2 is "order parts" then what parts?

Thanks a bunch. The engine on this beast seems just fine but the tranny sure detracts.

Paul,
I'll try and give you a little information.

1) what does the dremmel tool fix fix? I mean, what is going wrong that polishing with a dremel tool fixes?
A.) The "dremel tool fix" is a way of recutting the worn parts on the gears that actually do the "work" of shifting gears. If you look over some of the "transmission" Tech Tips, you should be able to get an idea of what it is we are trying to do.

2) do the symptoms i describe sound like the dremmel tool fix will solve the problem, or should we order some parts?
A.) The dremel fix will work for first gear, as well as second gear. Again, check the tech tips. I did a complete transmission fix on my "daily ride" over the three day weekend of new years. If you drain all the fluids, pull the battery, tank, seat, and handlebars, you can flip the bike upside down and work on the transmission easily. Pull the shaft as detailled in tech tips, work on the gears, ond reinstall.
3) If the answer to 2 is "order parts" then what parts?
A.) if you do feel you want parts, it would be first and fourth gear, if I remember correctly. Please don't hold me to the exact parts, as I do have a case of CRS that comes and goes.
Good luck, and make shure your son does a LOT of the work, so he will take care of the bike.

Your Fix is a Skip and a Jump away!

Hey Paul,

Check out this tip in the Repairs/Tranny section:1st,2nd Dremmel Fix

Diver is right, it's 1st and 4th that mesh, and 2nd and 5th that mesh. While you're in there, take a good look at 2nd/5th, cause it's most likely quite worn, and worth running the Dremmel on it as well since you're already there and have done all of that work already. Many have done the Dremmel fix and have found it to be a worthwhile and economical way to repair things. Others prefer to put in NEW parts, so if you have DEEP POCKETS, by all means, get new gears, they are still available.

The gears you want are on the CounterShaft assembly. SO, when you're looking for them in the Yamaha Online Parts section, you'll know what parts to look for!

thanks guys - any gaskets etc we need?

My son and i will try the drremmel fix next week. Are there any parts we need like a gasket kit?

thanks a lot for your time and help

Hey there Dadio,

The gaskets you need are the tranny gasket, and the shift cover gasket, the clutch cover gasket. You can get a roll of gasket material from auto store, trace them out and cut them out with scissors and Xacto type knife, then use a single hole puncher to punch out the holes for the bolts, perfect size! Recommend getting some Yamabond from dealer to use when refitting parts!

Hope you printed out the info from the tech tips to make it easier to refer to without having to come back to the computer?!

Looking forward to hearing your progress report!!

wait till the fluid is out of it, the oil pan is off, and he starts dropping gears on his head...lol...then he's committed...Just did my fix last weekend...and in all honesty, as long as you have the time and determination, it can be easily done by anyone. Even this beer drinking artic canadian
