Well, I picked up my Cabestany Replica last night and went straight out on it. To run it in I took it very steady for the first hour and just did quarter throttle stuff. The difference between this bike and my old 02 290 is huge, it is so light and nimble with heaps more traction. I have a section where I practice which I struggle to clean normally but I did on the second attempt on this new bike. So far so good. After about an hour and a half I had a go at a thirty foot tall steep bank which was flat out in third on my old bike, I lined my self up and attempted the climb. When I was half way up and onto full throttle, it was at this point I dissapointed to note that the bike wouldn't rev out and I only made it to the top by the skin of my teeth. At the moment I am putting this down to the engine being a bit tight but I will keep you posted on its development.
I was nearly ready to go home and was going for one more blast, I kicked it over to start it and the bloody kick start snapped off, needless to say I will be going straight back to the shop in the morning to get a replacement ordered for the weekend
On the whole I am pleased with it however if I am going through kickstarts every two hours I will not be happy!
Varying the revs and putting a load on the motor seems to help break in a new one. A WOT run in gear s 4 and 5 puts load on the motor, not to over rev it neccessarily, just the full working load through the range. This develops maximum pressures and gets some heat in the motor. Then let it cool and do it again.
After an hour or two of play, you should be able to fully rev it out to clean things. I often do this with a bit of a drag race(not on cold motor) and let it rev out fully to see if it will clean out on top.
You probably do not want to do anymore big hill WOT events untill you are fairly sure about the fact that it will clean out and rev out fully with some heat in it, or make a decision to change the jetting on the main because it will not clean out properly. Look at th PROS, the NEVER make a big attempt without clearing the motor!
Basci thoughts are that 28mm carb should probably require someware near a 125 main jet, similar to the Kiehin, and word to the wize is to do your own little strip and clean on a new bike anyway, just to be sure there is no mfng trash in it! Plus as least know where you are at on the jets.
