You can get rid of the slight misfire by opening up the plug gap and indexing it, so you don't need a new ignition.
The new reed block was introduced because the old tooling had come to the end of its life.
If you look at the old reed blocks, you will see they are numbered, showing that there were several sources of castings.
The new blocks chip reeds more than the old ones and show significant daylight through the closing edges unless you set them up very carfefully, there doesn't seem to be any improvement in performance though.
The new barrel has seen juniors setting times faster than seniors but is not worth the investment if you run a senior engine, as you can end up with a slower engine.
If you had stopped Rotax developing and fitting new big end bearings and conrods, then you would all be seriously out of pocket with wrecked engines.
The new clutch just HAD to happen because the old one was such a pile of ****.
Would you really still prefer to be replacing springs, shoes post retainers and backplates.
The new clutch has some faults but is a vast inprovement.
It's good to see Stars ignoring the greased clutch debacle.
Bombadier and the ABKC have set out their stall, the bearing must be greased, ther is no improvement with a greased clutch and grease will find its way on to the drum and shoe.
Leave it there, put it to bed and let people grease it if they so desire.
While the scruts are searching for grease, they are completely missing the other methods of tweaking clutches and it's right under their noses.
Let everybody 'grease' and the whole thing will be a lot more level because while they stop you greasing, the more canny amongst us don't need grease.
At least with the new clutch the thrust washer under the crank nut doesn't get a great big groove worn in it now and the end float stays reasonable.
Michael, if gearbox is so good, why isn't it the chosen class? Perhaps because it's more **** than Rotax :) Numpties? US!? HHmmmmmm.
