Apart from Tom picking up the bike for you, this ^ is GSR brilliance.

Simple and effective. If something has gone 'pear shaped' inside the engine you should see fragments of it in the oil.

Thanks for all the input guys....I will drain the oil tomorrow and look for any "floaties".


Ray, if it was the output shaft bearing wouldn't I be able to move the front sprocket by hand? Or am I thinking of the wrong shaft?

ANyone know if that motor is a plain bearing high pressure oiler or rollers and low pressure??

High pressure on the crank but the trans is roller like most bikes.

If it were an airplane would you take it up in the air?

I consider motorcycles in the same vein as airplanes. They need to be 100 % safe and ready for the road, for at 70mph if something goes wrong you will find out how merciless the nurses in the ER can be with those brushes.

Man that made wince at just the thought.

Airplanes have a LOT more room for mechanical error than motorcycles.

Yeah but that coast to the side of the road in an airplane can be a tad rough.

A popular misconception.

Update

OK, so the clutch looks fine, I can start the bike fine. But now along with the suddenly slack chain there is a problem with the shifter.

It acts as if there is to much travel. If you upshift you have to lift the shifter all the way upthrough its entire travel, it was not like this before. Previously it shifted very easily from one gear to the next. Now you can get up into 3rd or so, but can't shift any higher unless you push down on the shifter and then lift it back up?! Downshift is OK from higher gears, until you get to 2nd or so and Its really hard to get to neutral or first. You push down on the shifter, but there isn't enough travel, it bottoms out before it shifts, you have to lift it up and down and then it'll downshift.

I have never even seen the inside of one of these transmissions, does this sound like something anyone has head of before? I'm afraid that there is something seriously wrong in the tranny now and need to get it diagnosed quick...

Any input on what to look for or try short of cracking the cases would be greatly appreciated. I know I may have to do it eventually I at least want to try anything I can before I go that far.

Thanks for all the replies so far and I really hope one of the GS Geniuses can come up with some good advice!

One other thing that I noticed was that the shaft that the shifter clamps to had a lot of play when the clutch cover was off the other side. WHen I went to bolt the shifter back on it the groove the bolt fits into was almost even with the sprocket cover. It had to come out at least 1/2" once i bolted on teh clutch cover it was OK though. Is this normal or yet another sign a grenade went off in my tranny?

Well it may be cheating but I found a cheap fix...I picked up a Yamaha FZR600 today. My wife and I were riding bicycles in our neighbor hood and I jokingly said "Look Honey a bike for sale, let's look!" Dead battery, gummed up carbs. We jumped it and barely got it going so I could take it around the block to be sure nothing major was wrong.

It ran really poorly between the gummed up carbs from sitting for three years and the competely bad battery...I got back and said "Boy I don't know it'll take a lot of work...what would you say to $500?" ...."OK"

Wow, its got a Yosh slip on that is probably worth almost that!!!


I got some carb cleaning to do, but other than fluid changes etc I will be set. The tires were new when he parked it...only a couple years old and still with "tire hairs" ! Pics to follow...

Was just curious, I am compiling a list...
