Despite a cold lonely garage, I managed to get a couple things done today. First on the agenda was to get the throttle body and plenum seperated. I'd tried a couple things, but did not want to risk damaging the pot-metal TB housing. I tried a make-shift puller to push them apart at the injector-rail mounting holes, but it didn't seem to budge. Plan B was a little heat gently and carefully applied to the plenum with a propane torch. Success! At fist a little wiggle, the it popped right off. Once seperated, I checked out how it would work coming straight off the manifold.
Looks pretty good. I still need an injector in there somewhere, so I will probably end up adding a plenum between the TB and the manifold. I ordered a injector holder and some 6011 tubing this week.

) I called on Thursday to place my order and was told they were out of holders, so I sent Ross an e-mail. He told me he expected "some" on Friday. I got another e-mail from him Friday after lunch that he had gotten ONE holder from his machinist, just for me! Now how is that for service! I'm not even buying his controller (I'm using a MicroSquirt) and he went the extra mile. Must be because he is Canadian, eh?
After checking the TB, I re-installed the carburator and airbox for now, as I'm trying to arrange a base-line dyno run. Then I fitted the Willie battery hold-down. As I expected the relay that was in the way will not be there by the time I get to the Big White Dyno as it's actually a turn-signal flasher. I unbolted it and just moved it aside. I had to make a couple little adjustments, then drilled some 1/4"+ clearence holes in the 1/2" flanges. Using a transfer punch, I marked the bike and drilled holes to match. Once installed I found that the hold-down interfers with the seat-pan, where the seat-pan has a "bump" to hold the battery down. I'll have to trim the bump out of the way when I re-do the seat.
Once everything was back together, I took it out side and fired it up. After the usual long warm up with it backfiring, I rode it up and down our cul-de-sac a little. For some reason it doesn't want to run over 3/4 throttle - it feels like the ignition is retarded, but I bet it's just running way lean because of the aftermarket exhaust. I should have checked the jets when I had the carburator off.
OK, this part was just for fun:
OBS-cene sticker from Cafe press (it is a very long story, best told over a cold beer) and the 'Racing' from a local sign shop. Probably should have went yellow, but I kind of like blue.
After riding up and down the street in the sleeting-rain, I called it an afternoon and came in for hot tea. It's not much progress, but it's some!
