a Suzuki 1K??Not my Busa problem......
One of my Marines has a CBR 929 RR. Problem: Bike will not rev over 6K rpms, any ideas on what he should look at?
Thanks for helping,

Thanks Rob....thats what I told him.fuel pump / fuel filter
Then you told him right, Im sitting in the Kansas city airport right now.Thanks Rob....thats what I told him.fuel pump / fuel filter
Do you have a fix for it?The exhaust backpressure valve under the bike is a big problem with the 929/954 hondas.The servo motor that operates this valve via 2 cables has crappy plastic gears in them and they eventually fail.This makes the valve stay shut when it should be open & totally kills HP & wont let the engine rev up. Hope this helps
Outstanding Help....I will have him look at this.The exhaust backpressure valve under the bike is a big problem with the 929/954 hondas.The servo motor that operates this valve via 2 cables has crappy plastic gears in them and they eventually fail.This makes the valve stay shut when it should be open & totally kills HP & wont let the engine rev up.

This will work as a temporary fix (make sure the valve is open at all times).The bike will still be underpowered and will not run at its peak performance levels untill properly repaired.You can usually find a used servo at a salvage yard or get a new one from a honda dealer.If its like the Yamaha Exup Valve set up with the cables connected to it, just unhook the cables so that the servo can't open/close the little flap in the exhaust...
guessing they use this valve to create some back pressure to build torque at lower rpms?This will work as a temporary fix (make sure the valve is open at all times).The bike will still be underpowered and will not run at its peak performance levels untill properly repaired.You can usually find a used servo at a salvage yard or get a new one from a honda dealer.If its like the Yamaha Exup Valve set up with the cables connected to it, just unhook the cables so that the servo can't open/close the little flap in the exhaust...

Thanks Ken....My first thing would be fuel pump or filter, but Steve is infinitely better with bikes than me so I'd go with his thoughts.
