Hi all,
I went ahead and ordered a set of Lennie's rocket sprockets,after reading all the reviews posted on
advrider. After 2 weeks, I got an mail notice and then ran to the postal office to collect these two sprockets:
Last weekend I planned to have them installed, along with the crash bar, a new lambda probe and a set
of Hella FF 50.
First thing was to have the valve covers removed...
Nothing hard so far. Then, I loosened the screws that hold the OEM sprockets in place, using an 8mm
Allen key. Had a friend press the rear wheel brake wile the engine was in 5th so that the engine was
locked and the screws came loose.
While the screws were still loose, I had the engine turned to top dead center and started to remove the
sprockets when the piston was at TDC on the compression stroke. Then replaced the sprocket with one
of Lennie's, then moved to the other side of the engine. Okay, I might have missed enumerating some
steps here but I had lots of help from the install PDF that Lennie provided, which I have uploaded here,
so it may help others too.
After all was done, I checked that the marks on the new sprockets are horizontal for each side while the
piston was at TDC and that the valves were loose on just one side, then rotated the rear wheel and they
were loose on the other side, just like for valve adjustment.
Then I put the valve covers back on, performed a TB sync (nut sure if necessary, but I did it anyway)
and put the fairings and seats back on.
It was time for a test ride.
Wow! The bike felt like totally new. It pulled better from lower rpm's and had more grunt in it. When I
switched from my 1100 GS to my current 1100RT, the first thing I noticed was that the RT was lazier
than the GS, I guess from the final drive ratio that the RT has and the extra weight that the RT carries.
With the new sprockets, the RT feels like the GS used to, faster and gave me more confidence in
overtakes. There are a bunch of other benefits in this sprockets,listed on Lennie's site, among which
fuel consumption, making sense to drop a little,since the bike does not need all that revving like before.
Did not get the chance yet to measure the fuel mileage but will do it an report back with some numbers.
Although this post may seem to you like advertising, it's not. I have no affiliation with Lennie, just
installed this set of his wonderful product and like to report to others, so that they can enjoy a new bike
feel as well.
If anyone interested, this is the link to Lennie's website: http://www.boxerperformance.

too, definitely!
Thanks,
Dan.
