But just for sake of argument, what is the smallest cc the FACTORY installs on a 300 ish [img][/img] engine? And considering the stock 230 carb size.......How much bigger a cc do you need to go to install a 32mm?</end quote></div>
I dont know the biggest on a 300 or so size, but I have a 400 kodiak here that has a 32mm stock. The 250s came with a 26mm. The 250 4wd came with a 24mm....
Aah heck,,, where's my books.... Ok... the LT300E came with a 26mm. YFM350ER came with a 32mm. YFM350x had a 36mm. KLF300 had a 32mm. All the Hondas have keihin carbs and I cant tell how big those are from the part number. Also, my books end at 1992, so...
I know small carbs are used on utilities for the extra low end torque they give. Big carbs flow more air, but cost low end. I've also noticed some difference in CV type carbs and regular carbs. For instance, the 250 4wd has a 24mm up to 1989, then a 31mm CV carb after. I guess a 24mm regualar carb flows about the same as a 31mm CV. I've seen that in other quads too.
It would be nice if places like edelbrock would give a CFM chart for small engines like they do the big ones. But, I've looked everywhere and can't find anything except something like this:
I wish I could remember where I got that chart... I'd give a reference.

You could be right on the nomenclature... Decking the piston or decking the cylinder... Never really thought about it... But at least we're talking about the same thing. [img]i/expressions/face-icon-small-happy.gif[/img]
When I get my 70mm piston and new rod, I'll check the deck height and if its around .010, I'll mill off the extra. I'm wanting to mill the head because the head doesn't really have a flat part to match with the flat part on the piston for quench. Plus, it adds some compression.
Speaking of decking... I think I'll head out n see if I can get the other .040 off that lakota jug.... 8.5:1... What's up with that???

Check this link 230cc Conversion it says you need to use the longer 115mm rod instead of using the standard 107mm rod. Now I am confused.

No WOW for me! Actually I tried it, bored me to tears within minutes!
I think I may have gotten rid of my scale. I used to use it a lot in my youth, Uh, no need fot it now![img]i/expressions/face-icon-small-wink.gif[/img] [img]i/expressions/devil.gif[/img]
Rigged up a balance bar, 70mm drops 1in lower than .80 over, if I was fishing the 70mm would win!!!
