So how were the loose transmission gears that Greasy questioned you about?

....I replaced the cruciform and put the gears and spacer back and there was about .3mm of play so it seems good. When I first inspected the gear stack there was alot of wiggle, way more than my feeler gauge could read but i would say .5-1mm thus the clicking on roll I think.

Gears look very good!
I find this odd, unless I've misinterpreted here. you say that it was .5~1 at first, and then you put it all back together and it was fine at .3

gears don't just magically shim themselves by taking it apart and putting it back together again...

I'm not sure, there was definitely more play when I first tried them. After I put them back with the new cruciform there was much less.
Is it possible something wasn't sitting right? I forgot to notice but could the cruciform have been in the wrong way round?


Old and new cruciforms

Cruciform won't affect gear shim tolerance.

Disassembly and reassembly should not either. If it was loose before and you did nothing to fix it, it will be loose again.

Good question… I think it might have been on backwards… should wear on the left of the cruciform because of the way the gears bang into it, (looking at it from the gear selector to the back wheel) I think?

you may have sorted that with the cruciform but if your stack "becomes" loose again you will have staying in gear issues. I just wouldn't feel comfortable with that. I'm saying I think one of your gear clearance measurements was BS. The problem is we don't know which one.

True true, I am not confident with my measurement taking skills I was using the sip feeler gauge. It did not click when I first got it about a year ago, so maybe it was something else?
I did notice the exhaust was not seated properly and now it is.

I am inclined to leave it and if it returns go in again, does that sound reasonable?

When it starts doing it again, use the dry-fit measurement method that FinYoshi used to figure out what's really going on.

It's totally possible that your gears didn't need shimming.

"Clicking" is usually a symptom of a cruciform that has become worn so that it isn't sitting snuggly in the groove of the output shaft and is catching on the edge of either 1st or 2nd gear in neutral.

Your old cruciform was a mess. Replacing it probably was all that was needed. You'll know soon enough.

I'd rock it as is but if you have gear selecting / retention issues then you know what is needed.

So rode about 50 miles today and everything seems good with the cruciform. But after I parked I noticed a little spot of oil on the ground. After I looked, I noticed there was fresh oil on the cases, not a ton but more than was there after I put everything back together. It has about 20 k miles on it and I am thinking I should have done the oil seals? It seems questionable. While it wasn't pristine when I replaced the cruciform, I did give it a once over with degreaser.

On closer inspection most of the oil seems to be coming from where the exhaust connects with the cylinder head. I first noticed it when I put on the malossi 210.
Any ideas as to what it could be?

The oil on the cylinder head seems old and black, could that be the old oil re softened with heat? (When I first did the 210 install
The exhaust wasn't tight enough and it slipped down a bit and there was an oily mess from that. When I tightened and repositioned the exhaust it seemed to take care of it)
At the bottom of the case underneath there was clean fresh oil. I am more concerned about that.

that's not "oil seals" oil. that appears to be burnt combustion blow back-- from the pipe joint at the cylinder is most likely but the base or head could do the same.

ETA- you said clean fresh oil, so I'd say check your gearbox plug/filler gaskets and the case gasket. may need a little snug up on everybody.

either way, if you're huffing that much oil out of a seal you've got a big big problem

Makes sense the more I look at it. Is there a way to make that better or less? Her is my exhaust. Does it need to be abutting the cylinder head ?

This is the oil I'm more troubled by. Seems to be coming from the carb. Is that possible

the exhaust *should* be butted up tight. just don't go ape on tightening it up, you'll oval out the exhaust stub.

oil/gas mix can absolutely leak from the carb box. follow the trail and see what you got cooking. may need to reseal something up. I just recently has one that I wound up lapping the carb base and carb box and then goopifying the gaskets because it would not stop weeping.
