No problem.  If you haven't done anything like this before I would recommend getting the cheapest hoop you can find and do a practice run.   It isn't that it is really hard, it is more of how easy it is to mess it up.   But really that can be said of most fabrication.

I have tires! Unfortunately I made a rookie mistake and pinched the front tube.  So I have to get a new tube and pull the tire half way off.  I am going to make a tire changer, I figure for the price of even a cheap one I can do better.

Thanks! I'm pretty happy with the tire and wheel size.  Front is a 120/70r17 on a 3.5" rim, rear is 150/70r17 on a 4.25" rim.  Tires are shinko 705s.

Semi related to the build I got a second engine the other day.  Not much done on the bike as its mostly waiting on funds.

So I took advantage of diyautotune having a black friday sale and ordered a microsquirt.  I have a plan to do an in-tank fuel pump and have been working on throttle bodies.  After checking suzuki sv650, hyosung gt650, triumph bonneville, and k1 gsxr600 ITBs, I decided to use the ones from the gsxr as they fit the BS38 carb mounts.  Now, the apacing is pretty far off, but they are very easy to respace. 

 I will be mounting them "upside down"  for easier throttle cable routing.  So the injectors will be on the bottom.  The microsquirt will fit under the seat.  The only thing I have to figure out is where to mount the coils.  I'm going to use LS coils as they are fairly small, have a built in ignitor, and you can find them about everywhere.

Slight update, got a new front tube and installed it successfully.  So now both tires hold air.  Other update is I started making the block off plugs for the secondary butterflies that the gsxr used.  So nothing big looking to show change, but there is slow progress.
