The Chopper Compendium

Yes I figured as much. Aside from wrong parts. What do any of you think of that wheel formula?

Update: haven't done much except cut off the seat loop and loop support about 3-1/2" above the motor mount plates, and removed the gusset plate from around the steering neck. I don't have rims/wheels yet so kind of in a holding pattern on trying to design the rest. Does anyone know of a formula...

Ah, ok. Gotcha. I was under the assumption the measurements were taken off the oif frame from your other thread. Yes, the non-OIF vs. OIF are indeed different. Aside from the obvious, the tubing for the down tubes, lower rails, seat loop, swing arm are larger than the largest tube on the older model...

I came up with approximate numbers for both, just wanted to bounce them of either of you, or both. On swing arm, from c...

Curt, thanks for the offer. Much appreciated. The area I am looking at is cutting the swing arm bracket off the seatpost. If the whole tube that makes up the tank/backbone/seat post is the same dimension wall thickness, I can get the measurement off of it by using a manual internal caliper then take...

I do have a few questions regarding my build, but the topic of this thread pertains to my best bud's Trumpet ...
