TX Jeep, the gearshift system. Sometimes it does shift and sometimesit doesn't. Cleaned the valve body, reduction gears, cleaned the es servo, checked all the sensors according to the workshop manual. According to one of the guys at a Honda workshop they replaced the valve body. It solved the ES issues on both bikes. Did somebody on the forum ever replace the valve body and did it help? By the looks of it it'll be bloody expensive.
