Yeah, I got the slayer as a roller and I'm using the 2.5R out of my jato. I ran it for the first time last night, but it doesn't seem to shift... may have to pull the trans.
I think the 2.5R has plenty of snap for the slayer though. I did drop the CB to a 14T. If the ground hadn't been wet, it would have pulled wheelies. Just not sure how big of a jump the wide gears will make. May try and fiddle with it today... or will wait until it warms up again. Was in the 60's all week, then dropped to 30 and snow yesterday... yay midwest weather!
I have an OS18TM in a drawer, but I don't want to run that engine when it's this cold. Since it's not made anymore... parts are silly expensive, so I'd at least want to run it when it's less cold outside.
