That piston kit has been for sale for a while now so dont get your hopes up . A realistic price on that should be around 65-75 bucks . Check and see if the kits have a 1 piece or 3 piece oil rings and what sizes they are 53-56mm .

I would be interested in a crank if you have several for sale. And congrats on your daughters engagement.

Yeah like shortline said that kit has been on there for a while theres another pk kit on ebay as well for the same price, I would die for a stroker Im goin to go look at a 1980 110 today instead of this 83 I have

I know the members on here aren't aware of you superhuman abilities to find deals. I'm sure they have never seen a pile of fiberglass atc70 racing fenders either. Or mounds of aluminum wheels. Some of us know what you have found in the past though.

**KASEY** · 06-19-2010, 05:47 PM

ok here are a couple of pictures.. i think there are enough cranks for everyone that wants one ,, and the cam in the box,, there is 30 of those.. the h&s cams are the only and are already spoken for. i did find enough parts today to build me a stroker big bore motor,, so i was happy.. So i know what i have to pay for the cranks. i know they are old school. and i am not trying to get rich.. SO some of you guys that want one,,, PM me with what you think they are worth to you ,, and we will see if i can buy all of them at a lower price . there are 58 mm and 61.5 also cam chains in 86 and 88 links.. also can these cranks be used in a 125 m motor?

**honda250sx** · 06-19-2010, 09:03 PM

Kasey I'd love a set of them wrenches. Can you PM me please?

**shortline10** · 06-19-2010, 09:22 PM

These strokers are most likely for the points models and not cdi . Easy way to check it , points takes a bolt to hold the flywheel and the CDI uses a nut .
I dont think you could put one in a 125m for this reason also .
Any of those S&W valve springs gonna be for sale ?

**Vealmonkey** · 06-20-2010, 12:00 AM

Now if you really want to make me happy, tell me you found some heavy duty oil pumps!!!!

**greenhuman** · 06-20-2010, 04:20 AM

The 125M crank is different on the flywheel side in length and diameter (I am talking about the crank LOL).There is rod length issues as well.

**motoman1012002** · 06-20-2010, 01:15 PM

I like to have one of them cranks I pm'd you, this is sweet see all of the old 90/110 parts

**KASEY** · 06-20-2010, 05:23 PM

OK. I WENT OUT ON A LIMB HERE.. i made them an offer on all the cranks and cams.. they took it. so here is the scoop . the 58mm crank has a 14 mm wrist pin, the 61.5 has a 15 mm pin,, i will start fresh with PM'S so far no pistons .. i have 2 52mm pistons that fit the 14 mm wrist pins it says 90cc big bore on the box.. so what is 90 stock mm?

**shortline10** · 06-20-2010, 06:12 PM

Stock bore on a atc90 is 50mm and the stroke is 45.6mm .
Congrats on the score .
