Dump Valve Problem?
Hi all, tried searching but couldn't find any answers on this.
recently installed a new "Le Mans" Group A Twin Piston Atmospheric Dump Valve on my my01 bug eye. sometimes the valve is loud and other times its quieter when venting at the same revs. also i notice when the valve does blow off loudly, when i select the next gear, before i depress the clutch, the volume of the valve goes from loud to quiet in mid dump. the dump seems retarded and i have noticed that the rev counter momentarily jumps up before coming down when i lift off. Any ideas would be greatly Appreciated |

Unless they cooperate I suggest we all avoid the company, post their details and then let em know. Power to the people !!

Re: Dump Valve Problem?
The company i bought it from agreed to send it back, its Le Mans themselves thats no wantin to play ball. i think they push the piston in and cover the vacume pipe hole then when the pipe is released the piston springs back out. or somethin along them lines. this is what they were told to do by the tech guy at Le Mans. Its now been sent back to them for testing but i think im just gonna Stick OE
