What are my options for putting in a different cam for my 2000 Buell M2 Cyclone? Has anyone done it and want to share their opinions? | ||

A nice PRODUCT IMPROVEMENT is to keep the OEM CAMS and install 1.75 to 1 rocker arms ... This will give you better performance in the SPEED LIMIT RPM RANGES where we are supposed to ride and it will also show up on the top end ... PRODUCT IMPROVEMENTS on the INTAKE and EXHAUST help a lot too ... REMEMBER THIS: "THE DEVIL IS IN THE DETAILS !!!" | ||

I just did cams this weekend. Its bitchin! Andrews evolution sportster cams n4 | ||

with stock heads you are limited to cams with no more than .510 lift. The Andrews n4 cams would also be my recommendation. | ||

what buellistic said but I would recommend that you put the high ratio roller rockers on the intake side only and put standard ratio roller rockers in the exhaust side.in my opinion the intake is where the buell engine can be improved the most. this ups bhp (about 3) with no loss of torque and slight reduction in friction. most buell cams where designed years ago for the sportster engine and not for the requirements of buell.the best cam I've seen so far are JET ones but they only have half a mm more lift on the intake over the exhaust and the high ratio roller rockers will increase lift by about 1mm. also put in light weight push rods while you have the lower rocker cover off . this will help with less weight for the valve train aiding pick up and decrease valve float. | ||

"also put in light weight push rods while you have the lower rocker cover off . this will help with less weight for the valve train aiding pick up and decrease valve float" IMO this is very BAD advice. Lighter push rods will not do anything but increase the chance of bending a pushrod. Your cams have no issues with pushing the rods up and down. You can save valvetrain weight by using titanium retainers on your valve springs. If you do not want to believe me I suggest you call Smith Brothers pushrods and ask them as they are the leader in pushrod technology. | ||

you can get titanium push rods but very expensive I have aluminium ones and not had any problems in 7 years. I have the titanium retainers they save 12.5gm each but have to remove the heads to do this.i was trying to make as little work as possible so suggested the two jobs at once. in all my research on the subject any weight reduction in the valve train has a positive effective as long as reliability is not undermined and would have thought push rods where included in this ? | ||

I used to think lighter pushrods would help as well until I brought this subject up with Smith Brothers and was informed it was a waste of money as it does not improve performance. In fact on our race bikes we actually use a heavier pushrod to prevent deflection. | ||

I used the Andrews N8 cams. True bolt-in with no valve train mods required. Turned a black lab into a timber wolf! Highly recommend this grind! |
