OK ... so I have 9600 miles on my Blast and have not changed the gear oil ... prior owner probably did break-in change. I've seen the videos and read the instructions ... seat, battery, foot peg support ... bike up straight on stand ... drain ... refill. Book says "gear oil" but there seems to be a general consensus that there is a chemical in it that harms the wiring in there and to use 20w50 Mobile ENGINE OIL which I use in the engine also .... RIGHT ??? I guess my Honda Goldwing has engine oil in it's transmission since it shares the case with the engine, right ??? Why are Harley engines and transmissions separate anyway ??? |

I have used the same 20w50 V-Twin synthetic in the motor as the tranny, and it works great, and of course with one oil, that is one less thing to keep in stock, too. It is a recommended oil for the tranny. As for the last question: coming from a car repair background, I never thought that anyone would join the tranny and engine cases. There are bikes that do that? |

Engine and tranny cases are separate for a variety of reasons. First: Thats how its always been done! Engine oil gets a lot dirtier and much faster that trans oil. Engines and transmissions have different requirements for lubrication qualities, etc. There are quite a few automobile engine and transmission combinations that uses the engine oil for both. There is actually (at least one) one automobile engine and automatic transmission combination that used the same engine oil for both! However using the same oil and the same type of oil for both engine and transmission are two separate things. |

Well ... got the transmission case oil changed Sunday ... the bolts inside the frame are a bit@% ... had to stand on my head and hold my mouth just right. Think the same guy designed the oil change on the Buell Blast that designed the air filter change in the Goldwing ... |

There is a nice short cut to this on this site, where you drill a hole through the peg support for a screwdriver to access the one blocked bolt. I'm going to give it a whirl this weekend. It will cut your time down drastically, and encourage more frequent tranny oil changes, I'm sure. |

Or even shorter (and no drilling): drain as normal, fill through the trans vent hose. The whole procedure might take as long as removing the y-frame, but alot (A LOT) less work!!! Filling through the vent hose is slow, that's what takes the time. |

Please remind as to which hose is the vent hose. |

I found it. Yes, it can be filled through the transmission vent hose that is run up the left side of the frame under the seat. NOT the breather tube next to the oil drain. Its best to drain the bike hot and make sure its fully drained. Then add one quart through the vent hose. It takes 1 quart-no more. Its very slow to fill (cracking open the clutch cover to vent helps-but not necessary). If you spill a little, dont worry about it. It will probably take as long as it would to pull the Y-frame, but you can find other things to do while its draining and filling and its a whole lot less trouble! |

You reffering to the hose coming out of the block? |
