Interesting to read via Chrome translation ....
Fact is, most SGP riders do still need highly price tuning of their GM-machinery. Be it Graversen, Kowalski, Johns, Holloway, Karger, Kugelmann or others ....
Fact is, somebody has to pay for it. On the other hand, not only in my opinion time is overdue for change to lower this extracosts. The FIM has to make new rules. For example why not forbid certain expensive engine parts as camshaft, valves, springs, piston etc. Tuners are still allowed to do maintenance on engines but sellling highly prices special parts would be forbidden in order to reduce costs. These parts have to be homolagated by the FIM. Of course this would be the case for all manufacturers as GM, GTR, Godden and Jawa. A reduction of maximum RPM should also be major topic.
These rules should made compulsory not only in SGP but all Speedway leagues. Look how many clubs have gone bankrupt or having financial problems over the last years in countries as England, Sweden and Poland to name a few.
Massive cost reduction for 2021 is necessary for the sake of our sport.
PS: riders are always desperate for the fastest engine available, often somebody around them or a sponsor is prepared to pay for it.
