Well I finally did it. The ?DOO? that is.
My ?87A1 has done approx 133,000kms and last week I finally got around to installing some parts I bought over 10yrs and 60,000kms ago, namely the Cam Chain, Balancer Chain and most of the guides.( two of them can only be done after removal of the head and I didn?t have the time) I also took the opportunity to install one of Eaglemikes Balancer Tensioner levers(Doohickey). Once I had the 2 engine covers off I could see the DOO was still intact but the spring was just about out of tension. The coils were ?just? apart. I installed the new doo and the long spring that comes with the kit. I had actually purchased a genuine Kawasaki one in with all the other stuff but there was no way that was going in after reading all about them on the forums.
I can?t believe the difference it has made to the engine, it used to rattle quite a bit and the power down low wasn?t great. Now it pulls much better from a standstill and also when accelerating away from low speed. The engine is noticeably quieter and smoother. Both chains had stretched past the wear limits as per the manual. The cam chain so much so that the cam timing was out almost a full tooth at tdc. I just can?t believe the difference it has made. The engine probably really needs to have the piston/rings and valves done as well. Sometime in later this year I?ll get a leak down test done to check what else I really should do but for now I?m really happy.
I still have two of the guides, the valve seals, gudgeon pin and other small parts but I?ll install those when I pull it down totally for the major work.
