Could an 04 XB12 transmission be used in the 00' M2 Cyclone if the M2 trap door is moved onto the XB12 transmission shafts? I guess the shafts would have to be identical(shaft splines, size, length, etc. ), the case would have to have proper clearance. Maybe this could be made to work. Would the gear ratios be different? I haven't seen one so I don't know if they are even close. If I remember the gears are said to be helical instead of straight. | ||

Anyone? I've read that prior to 06' the gears are NOT helical. I've read that it could be used in the Blast P3 (not sure which years) but no real confirmation. Still no idea if it could work in a 2000 M2. | ||

The XB's don't run the trap door type tranny that our tuber's do. You'd be looking at pulling it apart and trying to fit all the various shafts, gears, forks and such into the sportster/Buell trapdoor faceplate thingy (technical term) once you'd split the cases and pulled your XB tranny out. Short answer, nope. | ||

I believe that the main and counter shaft and all of the gears start life as the same parts; however, this note from the 04' XB12 service manual shows that the 1st gear mainshaft has been modified. Bummer. The shift drum and shift forks and everything else is different. From 04' XB12 service manual: NOTE See Figure 6-66. The shifting fork groove on mainshaft 1st gear has been made 0.020 (0.51 mm) wider than existing mainshaft first gear (Part No. 35762-89A) to accommodate the new style shifting fork and has a new part number. | ||

Back cutting the sportster gears and putting them into a cnc'd from billet trap door is supposed to cut flexing in the plate down for more positive shifting, the back cutting of the gears smooths engagement. Zippers does very good work according to Preybird1, and I'm inclined to take his word on that. He's had a lot of work done on his X1 and knows who did it right and who effed it up (dealership). 'Course, all that costs a fair bit more than just dropping in a better operating tranny, like the XB has. |
