748 My New 748 Project

Discussion in '748 / 916 / 996 / 998' started by James Culora, Nov 25, 2020.

  1. I picked this up on trade for some paint work I did for a friend. Has about 23K on the bike. It needs some TLC and a good going through. I am amazed at how easy these are to tear down and work on. I'm doing a frame off clean-up and freshen up. There's a mix of 996 bodywork and I'll paint that all myself. I'm doing a black frame with aluminum subframe, and either Gold or Black wheels.

  2. I managed to get it cleaned up and made an engine stand so I can have the frame powder coated and detail and touchup the engine here and there. I will correct a couple leaks while its out as well. This is a fun project and one of many I've done through the years.

  3. Keep the photos coming, looks like you have a good size garage/basement to work in :upyeah:
     
  4. Looks like that will turn out nice. Black wheels best. ;)

  5. One thing with powder coat you may lose the chassis number on the head stock bud.
     
  6. when its all done, you'll probably wish you had kept it all as it came out the factory

  7. The ease of taking apart and working on the Tamburini bikes is such a good point. Ten minutes and they're stripped down!

    Machines designed by riders, to be worked on by riders is sadly becoming a thing of the past.

  8. I'm aware of that and in the past I've had the powder coater tape over with a 3/8" strip of aluminum (aircraft) speed tape over it just before they powder coat, then they can peel it off prior to the oven. Then after I can paint over it with matching black or clear to preserve it.

  9. I always consider that dependent on the condition of the bike overall and the collectability. This one is not that nice, but most certainly will be a looker when I'm done with it like all my bikes. It will be left stock for the most part, but cosmetically improved to my style and vision.

    Here's a couple bikes that I've rebuilt in the last few years. And the shop.

  10. Here's a 900SS SP, I found with 15K miles and didn't run. Paid $2250 for it and here's the before and after pics. Went from a Von Duc pinstriped mess to this.

  11. I found some more tasty bits on the 748, and some other stuff that need attention. Looks like it has a performance eprom in it too so getting some nice exhaust will wake it up a little. Some people should not wrench on bikes, I guess he didn't realize that the clip-ons are pinned in the correct position, and forced the adjustments. Also the engine is cleaned, but will need some touch up on the silver and the side cases.

  12. Decided to tackle the gauges and headlights. They needed some cleaning and repair of the isolators. The foam ring was nasty so I took it off cleaned it with some dish soap and flipped it over. I re-glued it back on. I buffed the plastic and the gauge faces to take off any swirls. The headlights were disassembled and I cleaned the inside with some car wash to remove the cloudiness of the projector lens and headlight. I removed all the black on the lens and refinished with SEM trim black. The headlight bucket structure I'm did in a bronze wheel color that will be the same as the lower forks. swing arm and clutch cover.

  14. Nice little spray booth, have you got a vacuum cleaner or some such behind the filter which pulls the overspray onto the filter?
     
  15. Yes, It's specifically for painting. I am a custom helmet painter and occasional bike painter, so I need to keep the garage dust free and off my bikes and projects. It's a Paasche here. https://www.paascheairbrush.com/product/bbf-4-e1/
    I have had it for 20 plus years, and I think back then it was $800.00 usd.

  16. Wow, that turned out great!
     
  17. Dupli-Color Bronze. They have a nice Gold too. This is very durable paint and dries hard. Its very resistant to normal chemicals and cleaners.

  18. I have only just come upon this thread. When I read your first post with the remark about "how easy these are to work on" I laughed maniacally and thought what a poor naive fool!! Having read through the rest of the thread I can of course see this is not your first rodeo and that you are extremely capable. Much respect for the work you have displayed here, I doff my cap.

    The reason for my initial reaction was that I rebuilt a 2000 748R that had been stored in a shed for some time, but most importantly it was my first ground up rebuild. I found out the hard way (and I do not have a mechanical background) that there are many traps for new players (which, with my temperament resulted in many tools, including power tools, being hurled across the garage - the dents in the garage door are a kind of history of the build and a form of artwork)!

    Anyway over 18 months I gradually got there as you can see below.

    BTW as a historical footnote (and you may well know this) the Ultimap FIM (Fuel Injected Motorcycles) EPROMs were made by Duane Mitchell down here in Australia back in the day - Duane was a long-time software developer for Ducati.
