Now what did I screw up?

[The Garbone]

Well,  I figured out my question of why those jets looked a bit off.  Seems I purchased a VM32 P0 jet and not a TM32 jet.   Attention to detail gets me every time.   Well, have the correct jets (p2 and o8) and a new needle on the way.   Ugg...

Just out of curiosity, do you have a header pipe that has the "hot tube" restrictor in the tail end, just before the muffler?
I know the older bikes never had them, but sometimes the exhaust system gets replaced along the way.
Just a thought.

[The Garbone]

Checked today,  no heat pipe in the end of the header.

   Ordered a Dunstall replica megaphone.  I hope I like it.

Was out of town for a bit so the bike has been sitting.    Reading this thread I really am tiring of this,  guess it would have been better to start with the proper jets as I am basically at square one.  Tried a P2 and 190 today still had issues.     Its odd in that it will rev fine if I nurse it past a certain point in the lower RPM range,  then I repeat and can't duplicate the condition.    I am wondering if it is electrical but in the feed to the coil,  maybe a bad connection behind the headlamp.   I think I will do some rebuilding in the next few days before I beat myself to death on the carb.

Do you have a 3-way timing pinion in the bike, or in your possession?

If you do, we can try some slight advancing of the cams with it. In some cases, if the intake cam is too far retarded, it can cause a spit at lower rpms.

If nothing else seems to work, we could try that.

Well,Garbone,you have helped me on here,and I feel yer pain,hang in there.Hope it is over soon.

You said you have checked the float, so presumably no petrol has leaked inside it. But did you check the float height? Just a thought!

[baird4444]

sounds like fuel delivery to me.
lo float??
gas cap vent blocked?
start with the easy stuff...never overlook the obvious- Mike

The carb has 2 floats actually.  Each slides on a pin on either side of the bowl.  I just flip the cab inverted and make sure the need valve is seated with the arms of the float lever thingy at the proper height.   

I will look up the procedure online and double check things next time I take the carb down.

The thing is the motor ran fine as jetted for the first 500 miles of break in.   

I have never been happy with the wiring mess behind the headlamp and at the moment I am leaning toward that side of the equation.   I may have buggered the harness between the switch and the coil when I pulled the tank.  Maybe a high open someplace that shows good voltage but drops it once current is pulled through.   Of course I naturally gravitate to playing with electrics since that is what I am do for a living.   

I had a thought to bring it to a shop for them to figure out but came to the conclusion in my mind (and I could be wrong) that most in the indi's in my are are Harley Chrome type guys. 

I will tinker with it some more Thursday and this weekend when I have time.

[The Garbone]

Well,  since I had been fooling with the wrong type of jets and my instinct was telling me go lean to no avail I reset my brain and decided to go with Aces suggestion of richer.

I am now at a Q0 and a 200 and the rig seems to be running better.  There is still an issue above 1/2 throttle and in my previous fiddling I had moved the needle up 2 notches.  I am hoping that moving it back down I will get the 1/2 throttle transition to work better.

Another separate issue I have notice is that if the points are closed the bike will blow the 20amp fuse on the battery.  Ehhhh.   It starts and idles fine without the battery.    I ohmed out the coil and it appears to be close to the value of my other Bosch coil so I don't know.... 

[ace.cafe]

I'm baffled.
You just have to try things to see what works.

[barenekd]

Since you are blowing the fuse with the points closed, perhaps you should try installing new points and condensor. Sounds to me like the condensor is shot. A shot condensor sends the timing all over the place and the points aren't really controlling anything. The juice from the coil will just jump the open gap of the points.

It sounds like we might be in the same boat,I'm have very similar problem

Well, I have an electronic ignition sitting on the shelf that I was saving for the 57'.  I will stick that in and see if it helps after I try lowering the needle two notches. 

I really need to get this sorted out so I can start working on the 57'.
