Nine Degrees

"These high-end CNC machined sprockets will advance the cam timing 9 degrees."


Whoa!!! Nine degrees cam timing is a bunch. I guess that would alter the torque curve some. Although I don't know much about the boxer motors. it's hard for me to believe that Bmw would miss the cam timing by that much, Seems to me they would just put in a different cam. IMHO

I am no expert on these issues but variable camshaft degree engines vary the camshaft timing by 30 degrees or more. I don't think the 9 degrees is excessive. I think BMW made a good compromise in where the engine makes power. For my riding, lower in the RPM band is better, especially off-road.

Varible Timing Camshfts

Well, varible timing camshafts and fixed timing camshafts are apples and oranges. A varible camshaft changes timing to optimize a particular mode of operation. A fixed camshaft is a compromise of all modes of operation. Big Differance.

Exactly... and BMW compromised in a different range for that motor. While that may be good for some of the bikes (i.e. ST or S models), it may not be as suitable for the GS or RT...

As you said, it's a compromise. 9 degrees is not much, really, but in this case it shifts the torque curve about 1000 rpm lower across the band. While most everyone I have helped with the install (S, GS and ST) has had great experiences, it depends on how you ride.

If you like WOT, and the upper rpm band, they are NOT for you. If you like low to mid rpm power and torque and the occasional burst, they will make you smile A LOT!

Lennie did a great job and it took him a long time and much testing to get to where the sprockets are right now. He knows what he is doing and on top of that, is a stand up guy! I can provide direct contact and have done so for a few folks already. He is revamping his own website right now and it will be up and functional soon.

NO, i reap no benefits from any sales. He is just a friend and has a product that I firmly believe in, based on my experiences.

I'll second the above post... word for word, even though Lennie's not even a friend of mine.

I have done a fair amount of searching on this and other forums regarding the use of these sprockets. There are not a whole lot of responders who have actually used the product. However the responses have been nearly 100% positive. I think they are worth a try and I have some on order. It may take me a few weeks to get them, install them, and evaluate them but I will give my feedback too. I have no friends or bias involved with any performance enhancing upgrades.

I was balking at the price, but fell into an Ebay deal at about half price & figured what the heck, won't lose any money to try them. Would I do it again at full price? Probably... it suits the way I ride & I love the jump it has a about 4000rpm.

does it do anything for the shake at 4500 rpm?

sounds like someone should do a "group buy" sale this winter when some of us have our ride on blocks! I'd consider!

I installed the Booster Plug and sprockets in March. I've been much happier riding technical single track (lug and chug then blip the throttle) and two-up with luggage on the highway. No regrets. I did a little write-up of the installation.

If you guys want to do a group buy, let me know. I'll talk to him.

He is slated to come over here anyway and maybe he can just bring a bunch of sets!? If not, shipping from OZ is easy enough.
