Small Crack in cylinder - how serious?

[Friedom]

I don't know if those are weld marks, or a sleeve, or carry over from the electro plating process. Do you?

Sorry I don't know... I wish I could help.

In the last pic... Is that a crack in the upper left of the pic?

Does a magnet stick to the inside of the cylinder?

Good question...

[Friedom]

I'll check..
It kind of looks like a crack that was repaired already.

Does not looked sleeved to me.

I would not reuse the piston even if it looks OK. I took that risk on my last top end at 150hrs. The PO had just put a piston in at 100hrs. Piston looked OK so I just installed new rings. Went to do the top end again at 200hrs and found this....

Crack one


Crack two


Very lucky. Sure I could have checked at 170hrs, but then what's the point? All that work and not saving all that much.

Yup. I'm waiting for millennium to give me a price for a wiseco and the works.

Freidom any word... inquiring minds want to know...

[Friedom]

OK word on the phone is:

Cylinder repair and plate: $275
Stock wiseco piston plus "20% discount off retail": $120
Port and polish: $425 (what??)

I'll probably source my own piston and send it to them.

I know many get the port and polish option... I prefer stock. Let's face it do we really use all the power available

It's pretty nice on my 92. But it was 200 or less when I got that done. No need for it here, thanks for the reality check.

I would skip the port and polish. $120 on piston if a little high, but at best $20 high.

Just got the call from Millennium. Cylinder repair and plate, wiseco piston "kit" and small end bearing: $444.45. She did read the details of the invoice to me, looks like the Wiseco piston kit was around $150. Hopefully that means it comes with a gasket set (I have another already).
I asked her if she could take .01 off the price and she said she could, but that was before shipping so it wouldn't be that cool of a number in the end.
So let's see here. $600 bike. $180 kips. $450 top end work. $100 fork guards. $50 stator. $50 bark busters.
So a little under $1500 for the bike.
OTOH it came with new tires, new ufo fenders(and light), new chain and sprockets, and a shiny new pipe. I took the best parts and swapped them onto the 92, so it's probably closer to a $1200 bike now.
Bonus: I can now ride twin play bikes with my brother or a friend and have a backup parts bike if something goes bad on the other.
Extra bonus: my dad (in his 60s) asked me to teach him how to ride a motorcycle. I never thought I'd hear that. Father son time FTW!

Parts are always more than anticipated... but in the end you have an awesome set of twins Besides having dad getting interested in your hobby.... priceless

At least you started off with a reasonably priced bike. It happens a lot where someone spends $1000+ on a bike that supposedly needs nothing only to find put that the opposite is true. Then they end up in the $2500+ range.

I called them in advance. Phone quote was ~$30 less. Ho hum.

So they removed my cylinder studs. Anyone recall if I should Loctite them, and what torque?

Yes on Loctite. I went with 10lbs and then tightened the head nuts to spec.
