Re: Question for 220 owners

Why not call a supplier and ask them? Both my 200 and my son's 220 has the 1409 on them, and as ted says, Kawi most certainly didn't use the same part # and let the employees decide.

Question for 220 owners

Post by Tioli »

Iv been through this as I'm in the process of boring a 200 out to 220. Ron did not want to use a 200 head for the project so I did a world wide search and they are hard to find.

The problem in my case is the 200 head has a machined down spark plug base. The 220 sparkplug base sits up higher. So doing the work Ron does is only possible for a 220 with a 220 head.

-The casting is the same for both parts. It has "1409" cast into it because it was initially designed as a 200 part.
-If it's machined to 200 specs it's part number 11001-1409
-If it's machined to 220 specs it's part number 11001-1410

+1 They all get cast from the same mold, and then are machined to the specific bike. The mold has 1409 on it because the 200 came before the 220 and they reused the same mold for the 220 head machining it for it's new application. This is common practice for manufacturers as they save on the number of casting molds they have to maintain.

The bottom line is that the 200 head CAN be machined to a 220 bore BUT then the combustion chamber is too small and would
require race gas to run with such high compression. Thats why we've all heard on here about some companies ending up with 225 psi of compression
when using the 200 head.

Fine if your racing but a little TOO high for a trail bike. Find a 220 head for your 220 ,,, there's one on E-bay for $90

Thanks for these explanations - now it makes sense. I've only ever seen the 200 heads and the combustion chambers looked cast - meaning they were porous in appearance. I had assumed that the 220 heads combustion chamber was cast as well and would have needed a different mold.

To add to the mix the head I picked up from Japan is a 220 thermostat model and is stamped 1411.

The combustion surface is dimpled and looks cast and has that all important raised spark plug perch

I got an email back from RB. He identifies a 200 head by the cast combustion chamber. The 220 has a machined combustion chamber and a dimple hole in the center of it. That dimple will make it easy enough to identify a 220 from just a picture.

Mine (1409) was machined and I have that dimple. Plug is not raised like the SR above. I remember that which is good as I don't remember much anymore.

The one on ebay you can see the dimple in the chamber next to the plug.

When I look at the one on eBay a few alarm bells go off. The 220 came out in 1997, the shape looks like one of Ron's all be it a tad old. The marks form the gasket ring are a little far back.
I would be asking for that head to be mesured from edge to edge of the combustion chamber.

I have a 200 head on the bench in front of me with 1409 casting and " NO " dimple in the combustion chamber.

+1 ,,, that's got to be the easiest identifier.

You can see in the ebay pic the machined chamber too. I agree the dimple is the easy give-a-way.
