my bike has been running rough so I decided to clean out the carbs before balancing them. I needed to replace a pilot jet in the rear carb and it behaved beautifully once I richened the mixture. The front carb was losing back pressure and causing backfires so I investigated the PAIR system. It uses an induction valve operated by vacuum from the front cylinder with the take off line on the inlet manifold. Once I removed the vacuum line from the induction valve and blocked it the bike ran like a dream, no backfire and carbs balanced perfectly.
My question is have any other Sachs owners removed this or do they know what bike it is off? It is a Denso valve operated by vacuum. I also removed the PAIR lines from the exhaust ports and fabricated two blanking plates.
I think the Suzuki 800s use a solenoid with a feed from the ECU whereas the Sachs uses a more antiquated and illogical system!
