New heater in the shed is proving to be a nice addition. I had the carbs off for a rejet and started thinking about my first engine. It only lasted to 24k when a con-rod bearing had a slight misunderstanding of what frequent oil and filter changes are supposed to do. So engine is out once again, I am going to tear it down to check the top end and possibly try my hand at porting the heads. This will be my tear down and build thread.

Got into the top end today after work, took just a few minutes.

Looks like its time for fresh Pistons and cylinders, Just a large spot of rust on the front cylinder.

Cleaning up the combustion chamber.

What are you using to clean it up?

What are you using to clean it up?

A machinist surface plate, wet 230 grit sand paper, wd40 and little figure 8's.

Maybe I should deliver my brake pedal I'm trading you and bring along my engine

Nice work

Haha, i think I'm gonna stick with this engine. A new cylinder and some OEM pistons I should be alright. Check your PM's

 

[JaredP]

wow I am foolish, the cylinders are steel and are bore-able this is gonna save me some $

Looking into a set of +1mm pistons from Zlock Racing http://www.zlockracing.com/new_products.html Sent an email off to them today.

I'd also consider just doing 'busa pistons. They require a heavy hone, but not a bore. And quality is great.

You could also go with the factory .5mm over piston.

Yep, why use aftermarket pistons unless you going 2mm over.

2mm seems alot to bore out of these, has anyone run into problems going this big? The +2mm seem to be the most common size I keep finding so I would assume they are safe, I dont want to assume anything here though..

I'm not sure my cylinder will clean up with a heavy hone alone. That's why I'm leaning towards just a +1mm over bore.
