Well I just completed my Monster Oval, power dual, and TFI. What a pain in the back side. I should have paid the $250. It was a lot more work then I thought. All total, it took me about 7 hours over two days. I took off the old yesterday and put the new on today. I walked into my garage to find a puddle of oil under my bike. The directions said to leave the two bolts that hold the mounting bracket (bottom two of the tranny cover) loose untill you do a final fit. Well I didn't realize that I couldn't leave it loose over night. All of my tranny fluid leaked out. It was a real treat. I finished the pipe install. Then I installed the TFI and that was not to bad . I had to take the whole tank off to get the the FI's (it was easier for me). After I got everything back on the bike it would not start. So I called the tech at Dobeck(GREAT PEOPLE). We tried to trouble shoot the whole thing. He said to me "I don't want to insult you, but is your kill switch on the handle bar off". I thought about it long and hard and replied no. Then I thought about it some more and realized that I took the great advice of this site. I disconnected the fuel line because I did not want to break the fuel port (Which I recommend and could not believe how easy it was). However you must remember to hook it back up. LOL!!!!! Needless to say I DID NOT!!!!! After my stupidity, I hooked it back up and it ran like a champ. Well I guess you live and you learn. Actually I would do it again tomorrow. Because of this site it gave to the confidence to do it myself. THANK YOU HD TALKING COMMUNITY!!!!!!
