I still haven't gotten back to the bike. It's been raining for 4 or 5 days now and I'm a hurtin' MFer it's too damp down there Waah!
Well, I 'spose I should bring this thread to a close. To tell the truth, I forgot all about it.
I dragged the better half down one day when the rain finally dried up. I 'splained what she needed to do and she watched the TDC finder go up and down with a good light while I turned the engine over with the rear wheel in 5th gear.\
We found that TDC was exzackly 4.0 on this particular TDC finder. The valves were perfeckly OK when I checked them as I thought.
I had had a shitty running experience previous to this and had dropped the bowl, checked that the needle was shutting off properly and removed the mixture screw and the pilot jet to blow everything out. I took the pilot jet out in the sun and looked with a magnifying glass and lo and behold there was a tiny piece of grit inside the jet in one of the holes. How it got through the super-fine filter in the tank and my inline filter I'll never know.
It started up OK on the third crank of the ES which is why I still have a love/hate relationship with this TM-32 Mikuni. I HATE the way the engine will just NOT stay running the first time no matter how many times I have tried to tweak the carb to make it so. I have made a hundred tiny mixture screw tweaks from the sweet spot and it's still the same story the next day. It will run a couple revolutions and no matter how quick and delicate I am with the throttle it will die and sometimes it dies with one of those horrible sprag clanks that slams into my brain like getting hit with a baseball bat and makes me want to just say F! this and get rid of the bike. If it does it twice I get so pissed hearing that sprag clank I want to smash the whole F-ing bike with a sledge hammer and just be done with it.
And I will go to my grave hating the fact that this engine will NOT kickstart cold. Period. And I'm convinced it's something to do with the characteristics of this carburetor on this particular engine (ACEhead with 9.8 comp). There is no tweaking I haven't tried and it still won't kickstart cold or get past those first 10 seconds after electric starting and keep the mu**rf**ker running on the first ES.
But then it runs so good out on the road and is an instant starter warm (both kick and electric) that it's like a dog that bites you once in a while, but you still love the dog.
Yes, I've gone one up and one down on the needle. Ran like shit both ways from the middle groove. And the richener is useless. It Will Not start AT ALL with ANY use of the enrichener.
