Those thansfers bridges are there for a reason , to support rings and also helps increase velocity in the transfer by making to separate channels vs 1 big sluggish one.
Have you noticed any difference between having them and not having them?I have cut those fingers out before and worked fine. Another thing is I have some old TM and Sanren 44mm heads, they didnt use the fingers like the newer ZK or other currently manufactured cylinders.
On one hand i completely agree removing the fingers makes more volume so lets more charge in but im wondering if with the fingers the charge just gets a higher pressure and velocity by passing through the fingers , and thinning out the fingers would have me afraid about having messed up the angle on distribution through the combustion chanber , like why did they add fingers if your better off just taking them off lolI don't have any examples but I remember reading on here a few people did thin out the fingers. As far as I know it worked fine. I have a few older 44mm cylinders with no fingers, one brand is Sanren
AbsolutelyIf you're running boost ports leave the fingers it will make the engine last a lot longer it also helps the function of boost ports causing a pressure differential.
If you're not running boost ports go ahead and carve them out.
I strongly suggest you try it with them in first it's very easy to take the cylinder out and remove them and then you will get an idea of the gains in torque that you get by leaving them.
I opened up my original minicross motor and its actually a 44mm lol and also with no split ports, ( has that decompression notch too that i heard isnt that good, but anyway after measuring the stock width of the ports on each cylinder the split one is not only deeper on one side but is also wider by a full 4mm at the base , which more than compensates the split, that said you could still remove them , bigger ports yes but will you sacrifice port velocity by doimg so?just a thought. When ADA originally produced these kits back in the day (2005-2007 era) they didn't have the split ports. China then copied their kits. The split ports started to show up in the chinese head kits around 2015 or so. And back then we would try to look for the head kits that didn't have the split ports. I don't think the cag motor is efficient or powerful enough to benefit from having them. We used to remove them when porting.
