    cleaning throttle bodies

    Sooo, over thanksgiving I cleaned the throttle bodies which were pretty dirty and looked at the reed valves which believe it or not were pretty clean. They did not look bad at all which surprised me after all the pictures I've seen. The intake valves had some carbon buildup but very little so I did not do anything to them. What I did find was that the rubber hose that goes to the reed valves had some tears in them so I cut and spliced them till I can get a new one ordered. I was  going to just block them off but did not know if it would throw a code even if the solinoid was still plugged in. My first time taking the tank off and it was very time consuming going slow but got it done o.k. Airbox slid right back on. Forgot to get crush washers for the gas line but i got by cause I used 1000 grit sandpaper and a straight block of steel and sanded them and reused them, worked great. A tip from an old mechanic that had done it a lot. So was it worth it? Well, yes and no. I found that some of my fears was unfounded cause most things were o.k. except from the hose and dirty throttle bodies. Also I no longer fear doing the job.

    Glad it went well for you and future requirements shouldn't be too bad.

    stjim, yea I am. The mechanic that did my valve adjust was definately in a hurry at least toward the end because there were a lot of body bolts loose and a couple that were only in about 2 threads. So he started them and then forgot to tighten them. That was from a very premier triumph dealer in the midwest whose name I wont mention. I did make a trip there to let them know I was disappointed with some of the worksmanship and that I hoped that the valve train was treated better, but all I got was excuses that he was busy and had lots of things going on. I got some extra factory bolts and put them in where some was missing so all is good now. AS said by many members, the job is not really hard but very time comsuming if your anal like me and wants things back together properly. I also took my rg bars to work sandblasted them and re powder coated them, and they came out excellent. Also the bottom motor mount bolt was  loose when I went to loosen it up to take off the rg bars. It had maybe 10 or 15 ft lbs of torque. So yes it was worth it. It is now how it should be. :001:

    Gonzo :

    Just curious :  is marijuana legal in your state ?  If yes, that may explain the sloppy workmanship.

    Your experience is a perfect example why I like to do my own work.  I think there is a much better chance the job will be done right if I do the work myself.

    stjim, no it is not legal in my state. I just think it is the sign of our times. The old work ethic is virtually gone anymore. Instead of saying "i'm sorry sir", we get excuses and reasons why we should understand why we got second or third rate service for a first rate price.  :110: fortunately there is a great triumph mechanic at a different dealership but it is 200 miles away. He is more expensive but his reputation is excellent.

    I have also heard that a lot of MC mechanics are under paid.  That may be a reason, too.

    Well, it was 60 degrees today so having my bike back together and it being the only clear day that was not raining or spitting snow and the roads dry, I am amazed. I took it out to see what difference the throttle body cleaning did if anything.I am amazed at the difference. The low end snatchiness is gone, the idle is better and smoothness in the acceleration is better especially at low rpm's. The bodies were quite dirty around the butterflys, caked on pretty good and I think it was catching a little at low rpm.  I also lubed the linkage around the butterflies and their shafts, that might of helped also. I had wondered if all that work involved in doing the job was worth it. I can tell you it was! :001:
