What's your time worth? They're cheap. Either buy a bunch more, or go with the preferable option of installing the extension tubes for future TBS's.
Care to elaborate on the failed TBS?
yeah, I bought the 5/32" inch tubing, and some spare caps, but the store was out of 5/32" couplers, so no way to complete the sync properly. Will try another store later today.
I was going to post my woes about the TBS in another thread, but not until I went back thru everything. I've been reading a lot of other posts and I suspect I just missed putting something back together correctly.
The short version of the story (actually, after typing it I realize it is not so short) is that I have the common stumbling/serging in low RPM on my Vee. I decided to sync the secondaries, then do the TBS, then the TPS and see if that works or if I need to spring for PCIII.
Anyway, what a pain to get the tank and airbox out. I'm used to working on my 77 GS750, so all the fairings and connectors were a big surprise. I got the secondaries dialed in with my digital calipers...required a full turn of the adjustment screw to get them in sync.
I put it all back together and started to sync the throttle bodies with my Morgan Carb Tune, but once the bike warmed up it started popping a lot thru the TBs...a lot...once it popped very loudly and made me nervous. It has never done this before so it was pretty discouraging that I'd done all this work and the bike runs worse.
So, I figured that my sync tubes were a little loose on the TB nipples...the inside diameter is noticeably bigger than that of the caps. I also noticed that I left the #2 airbox clamp loose. So, I put the caps back on (after a trip to the parts store to replace the lost one) and tightened the clamp.
After starting the bike it ran nice until it got warm and then it popped once, pretty loud. It didn't do it again after that, but it was getting late and I decided I'd let her sleep for the night.
My plan for today is to get some 5/32" vacuum couplers and make the carb tune (oops, TB sync) connection tight, take everything apart and make sure the TBs are still in good contact with the intake manifold (if that is still what you call it on these fancy new bikes), make sure I have all the airbox connections secure and the lid is on correctly, then start over from scratch on the TBS.
Thanks for the interest. Any advise is appreciated.
