Salut Carlo, Don't be shy you can teach me a lot of things, I am not very good for fixing motorcycle. Carburators ?? The two mysterious pieces connect to the motor !! Oh yeah, I have this nice sound when I release the accelarator POC POC and some time POC POC POC. I am pretty sure that I have a problem with the carburators. I need help for that. Keihin FCR 41mm Back fire when I release gas. When the motor is cold if I open the gas more than 1/4 the motor stop. After a few minutes it's ok. At the speed of 140km/150 km if I turn it wide open I have nice Beuuuh ! not enough gas or too much ?? I have the original valves on the tank, I have tried two new valves with tubing connect directly to the carburators. Same problems. I have some scientific numbers for you, Main jet = 150 Main air jet = 200 Needle # OCELV Needle setting: second step Slow jet = 52 Mixture screw: 1 3/4 turn Slow air screw: 3/4 turn Float height: 9 mm The motror have oversize piston and bigger valves.

Ciao CARL, if you tell me that Dell'Orto carburetors, I can have some references, but with that kind of carbs I do not have references. That said, I can assure you that the problem is not the oil cooler, but a lean fuel mixture. You do not have to use your bike, you risk a puncture piston. You consider that my main jets (dellorto) I have a 165. I ask for help to the friends of the forum, who homing carburetors Carl, please speak !!! I would make an attempt with the jets of up to 10 points higher. Following control the timing of the engine, and check the clearance between the valves and rockers opening. However, I think it's the carburetor. Check the exhaust pipes that does not leak from the exhaust gases tested. I hope that was helpful. Excuse my English !! |

Thank you Carlo I am not riding anymore, my next ride is going to be in 2015. It's already winter here the first snow is coming tomorrow. I have all the winter to fix it or find somebody to fix it. I guess I have to buy a few size of jets and do some tuning next spring. I am going to install the new oil cooler I have it anyway. Thank you Greg for the link about the Keihin tuning. If somebody have Keihin FCR please let me know your jetting. Thank's again Carl |

The Carillo rods in my 900SS have positive oiling to the piston pin by way of a hole bored up the center of the rod beam fed by the big end. Been running the same rods for 20!! years and have never had a problem with pins or rod bearings. It was an option offered by Carillo when I ordered them and I think the hole was done with electro discharge machining before the heat treat and shot peening. |
