[Screamin J Pito]

Your motor is now the besktop pic on my computer at work! Hope ya dont mind. Great build so far man! Cant wait to see how it'll turn out.

thats one clean looking motor great job.

Thanks for all the comments on the motor. My girlfriend's starting to get a little jealous of her

Finally got to turning up a new fork stem. Here are the dimensions from Black13 if anyone has to make a Big Twin springer stem.

Thanks for those specs Black13!


One inch Big Twin stem:
- length 10"
- thread length from top to bottom is ~ 2.5"
- Bottom of threads to top of bearing race locator ring ~ 6 5\16"
- length of ring from top of it to bottom ! 0.214"
- splines from bottom of bearing ring to end of stem ~ 1"
- O.D. of stem {measured at middle} ~ 0.990"
- O.D. of bearing retaining ring is ~ 1.032"
- top external threads are 1x24"
- top internal threads are 3/4x14"
- bored hole through length of shaft at around 29/64" only needed if running steering damper. will extra clearance at top if running steering damper for spring. So I enlarged bore to about .60" to a depth of 2.5"

I didnt cut any splines on the bottom just a .0015 interference fit (which worked out to 1.0045") with the fork and a couple spot welds on the bottom. Made a little brass drift which fits inside to hammer on so as not to damage the top of the stem.

Now I can get back to putting this thing together, welding up my bars, finishing the seat mounts and getting that motor in.

Here's a pic of the repair with the old shortened modified stem which was also lacking the bearing race retainer.

It's builds like this that inspire me! Word of warning if your girlfriend ever asks how your love life is going don't respond not to hot I cant seem to get the exhaust right! Tried it, thank god it was my B-day or I would be on the couch.

Keep the pictures coming!

[kngkong]

Sorry for the slow progress and all. Most of my time is being spent on another bike which I dont think fits the JJ... yet. Thanks for all the comments!

[HKNY]

Holy shit this is going to be insane when finished.

[kngkong]

Finally rolling again.

Got my seat mounted a couple days ago. Made this front mount which goes into the seat tube and a hinge bracket for under the seat.



What do you think of running this tank? I think its off an old yamaha moped? I would probably need to taper in the rear a little bit but Im kinda liking it.

Am I crazy?



Next step getting the fender mounted.

on tank,,,yes

[el diablo]

that bike has got an awesome stance ,but that gastank doesn't seem to follow the lines

if you wanne "go different" with the gastank
than maybe an early yamaha XT 500 gastank would do the trick for you

i like your clean work ,keep the pics comming !!

I agree! How about something simple like a wassell, I think a wassell banana tank would be perfect!

mmmm, yes wassell would be nice.

but, one last attempt. What if its tilted like this? I really need to get the motor in to tell. And I would still plan on modifying the rear of the tank a little.

Still not doing for ya?



Taking tomorrow off, will try to get my fender mount sorted.

Yeah that's better now!

[kngkong]

Thanks for the opinions. Im not married to anything yet, will see later down the road but would be fun project as the tank needs a lot of work. Getting fender mounts done today hopefully. Later...

I don't mind the dirtbike tank but it looks too long to me, maybe if you sectioned two or three inches out of the length.
