Me again.....
Cams note PB, might this be correct??

Dear Sportster Specialists!
Might anyone know the difference ( other than the main jet ), between a Big Twin Tillotson, and the Sportster Tillotson?
Should my 1967 XLCH have a specific Sportster carb??
Currently I am running an HD 1C, with an 057 jet.
My factory parts books, note different part numbers: Sporty 27162-66C, and the FLH 27160-66A
Many thanks!
Tony Blain #7543.

Many thanks, good advise.
Yep, timing to the start of the narrow lobe, yep correct gas tank with the vent that the outlet line of the Tillotson connects to.
Will try checking the cams.
Appreciate the advise,
Regards,

Do you have the correct tank and both the inlet and outlet lines on your Tillotson?
You say you are timing to front cyl compression. Are you using the narrow points cam lobe?
All the cams should be marked "P" and the number, 1-4 starting from back to front. It is possible for the two piece cams with a pressed on gear to slip, causing problems. A degree wheel will tell the tale.

Howdy, long time AMCA member, first timer to the Forum.... Enjoyed reading all your XLCH correspondence, as I try and get my recent acquisition, a 1967 XLCH up and running.
It belonged to my good friend David Hense of Mke, who passed. He never quite finished it, and I have enjoyed getting her roadworthy and up and running. I have a number of mainly unrestored Hydra-Glides, Knucklehead, U and W model Harleys in my collection and am conversant with their servicing and repair. The " modern" 1967 CH, I have to admit, has me nearly beat....... I can not get it to start easily, and when started, it runs real RICH, then pops through the Tillotson and stops. I have done the following:
1) serviced the Tillotson carb, in fact put another one on to check. NO difference
2) Pulled the cam gears out to check correct timing, all AOK
3) Took heads off and checked for cracks, all OK, reground the valves and resealed manifold with new O rings, NO difference.
4) Had the magneto re magnetized, and replaced the condensor, NO difference.
5) Set the mag points to .015", and put new HD 3-4 spark plugs in, No difference
6) Timing front cylinder on comp stroke to the single line timing mark as per my factory manual - NO difference.

This has me beat, I am missing something!!
Would any of you gentlemen know what the SECOND set of double strip timing marks are for on the flywheel?? A few degrees AFTER the single timing mark - Should I be timing to these marks?? I have tried it, but seems retarded.
The only other thing I can think of is that my buddy Dave, may have used the wrong cam gears, or they are not matched.
I did not measure them when I had them out, and assumed they were OK. From memory, they had marks on the inside of the lobes.
Are there any details on what 1967 cams should measure??
I was hoping someone might be able to assist my challenge.....
All the best and thank you,

Murph,

You're correct about the pre-assembled harnesses. I bought one for each bike I have along with bulk amounts of each cloth wire color and each loom cover size. on my big twins I used the harness kits as a starting point and modifed them as becessary.

My business is, and has been terrible for the last three years, so disposable (ie; motorcycle) money is very tight right now. Therefore, the it will probably be another year or so before I'm ready to assemble the big pieces and and wire it up. I completed the motor a while ago, with the magento being the last piece to 'get right'. I did spend a few dollars to re-magnetize the rotor and also ran the magneto up at Morris Magnetos in New Jersey to insure that the spark is as strong as it can be. Once the primary cover is re-chromed, the motor can be buttoned up, shrink-wrapped and placed on the shelf.

In the meantime I'm doing all of the detailed stuff that takes more time and parience than money. Two things that I don't do myself are paint and chrome and both are expensive, So those tasks will have to wait. But its a labor of love, so I really don't mind the wait. There's a lot of stuff to detail out on the other bikes.

I understand all too well on your situation, this bike took damn near 11 years. Babies, new house and the like didn't make things go quick.

I will send you what ever pics you need so take your time, and if in doubt don't do anything until you ask. I have lots of pics or can take some of a specific area if needed. I have found it better to make up your own harness rather then buy the pre packaged ones. they are not right.

[billpedalino]

Yes, I have the wiring diagram. But they often don;t tell you where the loom legs run. I had to look at a lot of bikes to determine the correct runs for my 47 FL. My 53 FL is very similar to the knuckle. But the Sportster is easy after looking at your pictures and jogging the cobwebs off of my brain..

By the way, that fuse block on the regulator mount is a very nice piece - I believe they only made it for 4 years. I'll bet that was hard to find!

[murph]

Everything meets at the horn, kind of like a junction box there. Do you have a wiring diagram? It will be a little more explanatory. I can look at my book and try to post if needed.

[billpedalino]

Thanks so much Murph. Great pictures and very interesting.

Your wiring layout in the above pic shows all. So if I understand you, the tail and stop light wire harness meet the harness from the regulator at a point below the front-left edge of the rear fender (near the left side swing arm pivot) where the stoplight switch ties in ?

[murph]

Here are some shots of a high fi purple I did maybe more detail of what you need.

[murph]

The wires never ran along the back of the frame tube by the rear cylinder, they came all the way down the fender and out the bottom, then ran across the engine case to the horn area.

[billpedalino]

Hey Murph,

Do you have any pictures of the left side of your Blue '62 showing the correct wire loom runs - especially up the left frame tube, behind the rear cylinder, and around the stop light switch .

By the way, I printed oput your previous pics on this thread on large-format, glossy paper to use as reference. Thanks so much for sharing them. My memory from over 40 years ago (pre chopper days) is sometimes a bit foggy, even thoug I worked at a Harley dealership back then! One look at your pics generates an 'Ahh Yes' moment every time!

Thanks,
Bill
