first test run one question
Just got my 2000 Virage tx 1200 carbed in the water today for a couple short runs. I have a new cdi, lr505, all new fuel lines and plugs, carbs were gone threw new kit everything looked good,120psi on all cylinders 23 degrees timing at 3000 rpm.
The 3 things Im sure I need to check are
plugs
piston wash
drive shaft coupler
The ski barley comes out of the hole without bouncing off the rev limiter I figure coupler is slipping but could that cause a bog around 5500rpms after 200 yards or so full throttle? If im easy on the throttle and get up to around 3500-4000 rpms I can pin the throttle and it will rev and pull good for a couple hundred yards up to 6500rpms or so but starts to bog down or break up and hang around 5500 rpms till I come back to part throttle for a few seconds then I can go again. It idles good and and mid range performance is good but it should be running pretty rich cause I added some oil to the gas thats in it cause I was worried about the oil pump since the ski has been setting since 2010.

Are you running the engine with five year old gasoline?
Adding oil to the gasoline tank does not make the fuel:air ratio 'richer'. It adds oil for engine lubrication but actually makes the gasoline to air combustion ratio more lean.

no its all fresh gas. Leaning out could cause the bogg correct? I stopped on one run and pulled the seat up and all cylinders were warm to touch as was the exhaust.
