Why am I getting gas in my oil? This really pisses me off, I just changed the oil and it has what seems a lot of gass, oil very diluted.

Pop the air filters off, and see if fuel is dripping out of the accelerator pump nozzles. If so, it's leaking into the engine past an open valve, past the rings, and into the sump. Rebuild the carbs, paying extra attention to the screws holding down the nozzles. The other option is a leaky float or needle valve causing the bowl to overflow, although that usually makes an external leak.
btw, I just discovered there are "old" and "new" IDFs. The "old" IDFs have roller-tipped accelerator pump levers (the bit under the carb that is pushed by the pump cam), and take a different pump diagphram than the "new" IDFs, which have a different lever (no roller). They are not interchangable, and if you try to use the "new" diagphrams in the "old" carb, you'll end up with no accelerator pump. The lever will be very loose when everything is assembled. The only place I know of that differentiates between old and new rebuild kits is CB Performance. Most places seem to send you new kits. |
