I recently bought a 1200 Trophy that would not run and had flooded the crankcase with fuel. I have drained everything, replaced oil and filter and a compression check of all cylinders is good.

I have the carbs apart and the o-rings on the floats were all dried out and I have replaced them. Daytonacharlie had a post about setting his carb float heights to 19mm (same Mikuni carbs, different bike) which has worked for him. Has anyone else experimented with different float settings on their Trophy? Since it is such a pain in the a** to get the carbs in and out, I would rather make sure instead of experimenting.

Thanks, McG63

Set the float height to 14.5mm. Pilot screws out 2.5 turns from lightly seated and it should be just fine. Lowering the level can cause it to run lean. Also, check the float valves to ensure the rubber seals are good. After everything is cleaned and re-assembled and re-installed, make sure to sync the carbs and set idle to appx 1100-1200RPM's with engine hot(cold will idle appx 900-1000). Also, use the center stand for extended periods of unuse, the float valves sometimes leak a little on the side stand as the fuel evaps out of the bowls. Periodicly check the fuel petcock to ensure no fuel leaks when in the RUN and RES position with the engine off. If it leaks, it can flood the engine(sounds like that is what happend to yours). If it leaks, get it repaired ASAP. Check all the fuel lines and replace if dry-rotted, cracked, split, or gummy(5/16" ID auto fuel line), the same with the vacuum line from the #3 carb to the petcock(1/8" ID auto vacuum line).

Hope this helps.

Thanks for the info Erv. I have replaced the fuel lines and also installed a tee for the vacuum lines so that I can get vacuum from 2 carbs.

I have checked the petcock and in run it does not leak so I think that the past owner left it on prime and the float seals allowed the fuel into the crankcase. I will verify everything in the next week and let you know if everything is fixed.

I have to check into how to syncronize the carbs.
