Well if I do rebuild the crank to suit the 16mm piston pin I'd need a rod with a 20mm big pin & 14mm wide. That isn't a common animal from what I can find. Even if I were to shave 1 mm & accept a 16mm wide 20mm rod.

I have a GasGas TXT200. Its an '00 that I've had 10 years & is pretty mint considering how some people look after play bikes. I've already had a text as a result of that one statement. Heck I dunno, I'm waning between wanting the money to do stuff & then on the other hand I love riding the Trials bike & looking on TM you need to fork out quite some wonga for a replacement.
I'm trying to work out if there is anything else I can sell that will bring in some decent cash. I should stop looking around until I get home, I need my job still.

What length are you after Dave?

std is 100mm, but longer is better. I'm not finding much that isn't for a Vespa.
It would be a crank build for this piston as other pistons I may be interested in including KT are 14mm. But that requires another crank set up anyway.

You have looked through Kevin breen and Samarin and the mad Swede Roffe sites i guess as well as ProX?
Someone (in the industry no less) is always harping on that Vespa's are real performance bikes i guess?
The euros do some real odd ball stuff with rods lengths and sizes i found a odd one (Monessa) i think that was something like 118mm with a 18mm crank pin and a bucket sized little end yesterday. But surely you can't have many YZ100 pistons left Dave they have been listed by Yam since at least 1990 as being available.
The cagiva looks promising not sure it has the width at the bottom though guess you have deleted the thrust washers?

I seem to keep buying them. This is my 4th inside about 4 months, I really can't afford this.

There is also probably a group of YZ100 restorers on plus.75mm bores forming a posse now Dave, as we speak.

Nah I'm on +1mm now, 0.75 was too loose.

Dave i seen this the other day obviously not the right size for you but they are quite different than your current design
its translated but you will get the drift.
This is a shit clever idea of being able to rebuild the pistons with 14 mm piston pin diameter for engines with 12 mm piston pins
Perfect to push the sleeve into the flask with a mandrel so achieves perfect paralellitet to 12 mm piston pin just slides in easily.
Outer diameter 14.00 mm
Inner diameter 12.00 mm.
Lengths from 8 mm

l dont think dave will get it builtin time but l have the record for the fastest build lol

What are you on about Scott? Its been to two Taupo GPs. You were at the last one.
The question the thread should be taking is "Will it be ready for the next Taupo?
Bike went BANG at Easter. There was a minor seizure at the back of the barrel, I sanded that out at the track & went easy for a session. Then next race in 2nd it let go big time. Slung it in the van. Had a quick peek yesterday & the head & gearbox are likely ok.
Seems a small bit of the barrel below the boost port dropped out. Actually can't find it.
Don't you look at my accountant.

Found! in the exhaust pipe.
And as no one took my lead-in pitch the bit below the barrel that fell out, was really pushed. By the rod.
I don't think I will use piston pin adaptors again. Actually I know I won't. They only need to move inward a little & they will interfere with the small end. When I took it apart the first time the bearing was a little blue, but as the piston had shattered I noted it but continued -after replacing the bearing.
No, time for a new rod size (some of it was in the pipe too).
So now I have a slot from the boostport down. I could just bore it for a KT piston & leave the slot, or I could fill it in clear of the bore, or I could weld in some liner & rebore it then.
I have found legal rods for YZ piston (RGV, but still needs 22mm bore pin), but that limits me from ever changing. With a destroke there are also legal options for 20 & 22mm pins. And lots of illegal ones, but no point going there.

your a good whine up lol . l dont know why but 2 strokes seemed to last better in the old days
