and the team negotiated with Yamaha to reduce the price, but Yamaha rejected this request. Therefore, the team side has been requesting to change F2 to F3000 from next year, and a three-way talk between JAF/team/competition organizer was held. The JAF insisted that F2 be continued for four years (until 1988), but the team and the competition organizers strongly requested the transition to F3000, which can reduce the cost of participation. As a result, in 1987, F2 was changed to F3000 ( All Japan F3000 Championship ), and F3000 was excluded from the All Japan Championship under the supervision of JAF in 1987. 1987 In 1987, Aguri Suzuki and Kaoru Iida participated in the GC at Yamaha. Since the GC also shares the engine with F2, we will keep an eye on the situation regarding the transition from F2 to F3000 and balance the F2 and F3000 engines (difference in minimum vehicle weight) in the direction of balancing according to the vehicle regulations. I was looking for it. Ultimately, the OX66-equipped vehicle weighs a minimum of 560 kg, which is 10 kg heavier than last year, but the F3000 engine-equipped vehicle weighs 610 kg and is equipped with a 9000 rpm rev limiter. Volume restrictions have been tightened for all vehicles. (From 115db to 110db) Suzuki decided that he could compete with the F3000 engine-equipped car with a lightweight, but the power of the F3000 engine-equipped car was so great that he could not win the championship, but the highest ranking in terms of results was fourth in qualifying / third in the final. He achieved a good result in third place in the series. References Yamaha products Formula Two Engines by model Gasoline engines by model V6 engines
