The XL shifter pawl mechanism is awfully sloppy even when new ... Once I switched over to GP pattern it worked a lot better ... It appears that it requires a lot of force to overcome the slop ... Joe

Looking forward to the new pics! I had a ton of shifting problems with mine Joe. I changed the detent plate and all of the springs and it helped. I think the stock part is number XXXX and mine is XXXXA.....the A being the recalled or upgrade detent plate. The new ones are shaped in more of a triangle configuration than rounded like the stock plate.

I decided to use a Morse cable to shift the bike ...



Rear peg shifter side




I used a solid  5/16 stainless rod with rose joints at each end and an old ring spanner mid way as a guide and it works fine if you have probs with the cable arrangment








its about 3 foot long

Does anyone backcut the transmission gears to make shifting easier? I know a guy we used to use in Philly who is THE foremost Sportster authority on the planet. He can do backcutting. I have an electric shift setup from Dale Walker/Holeshot for sale. $75 Friday

Also it looks like with the front end being way out front and you and the motor being way back that your center of gravity is going to be close to or behind your center of pressure..............something you should look into for stability purposes?? Hopefully someone with more experience on the subject will chime in.........

Scott - -

Back in October in the Build Diary you spoke the term "center of pressure."

I haven't heard of that term before and I'd like to know for a future build. Could you or someone explain that to me. Thanks.

Winter is upon us in the Northeast and I have been distracted off the project by the damn job ... too many hours and no time for build ... have plans to get into finishing the build starting this weekend ... all good here and the ground is now clear of snow on Long Island ...

it works well statically ... not sure when the engine is running ... I dont use downshifting to slow down at Bonneville or Maxton ... the Sportster / Buell cam drive key design is a bit fragile when it gets drag load ...

ok, thanks. i need to be in 1st gear to get off salt
@ 20-40 mph.

overall gearing is to high and would be lugging engine.

The bike is finally finished .... test drove it front of the house and discovered that it is definitely designed to go straight. Got to the corner and it wouldnt turn. I had to shut it down and walk it around. Also the lay down position doesnt do much for your feet as out riggers ...
