the 44 tooth...is that the 2 speed or the 1 speed??? I guess if you can find a gear that is the same setup it doesn't matter what the size is...I've got a few different spurs and a few different clutch bells for mine...but have to get it running good before I start messing around with ratio...Just remember, the 2 speed, you have to keep the same teeth difference as stock...so say you go 2 teeth smaller on the second gear, you'd have to go to a clutch bell that had the same first gear, and 2 teeth larger on the second gear...The lower the ratio, the less pick-up and more top speed..The way you figure out the ratio is you divide the spur by the clutch bell...so say you have a 44 tooth spur and a 16 tooth cb, your ratio wouold be 2.75:1 and if you had a 42 tooth spur and a 16 tooth cb, your ratio would be 2.625:1...also the smaller clutch bell spools up quicker where as the larger ones take longer to get up to speed, so if you had a 2.75:1 ratio with a 14 tooth cb, and a 2.75:1 with a 17 tooth cb, the 14 tooth would have more torque and more RPM...I hope this rudimentary explanation helps...Oh yeah, one other concern...Do You have Clearance for the changes you want to make...
