71 Indignant CB175 - New Updates!

Just a question on the honing...how can you tell what RPM your standard Craftsman drill is running at...?  This video says don't exceed 1200RPM for a chainsaw cylinder...

Could you hook up the drill to you bikes tachometer via its cable? (ratios?) idea only?
If the drill dosen't have variable speed, it should say on its label max rpm?

Thanks for the idea.  I think that may be too involved though. 

My drill has RPM ranges of 0-440 / 0-1600 rpm, low and high, respectively.  So, I think if I dial in a mid range number in high, I should get around 800 RPM.

If anyone has any experience with this, feel free to chime in.

Sneak peak...at the carbs.

They aren't finished yet, but I was so bummed about how voracious the lemon juice was since it started eating the grey "paint" that comes on them factory.  I was prepared to mask them off and repaint, so I got out the little dremel wire wheel and went to work prepping and the old finish came right off leaving a nice almost polished aluminum look.  Hurray for me.  Anyway, here is the difference just a little time with the wire wheel made.

Little update, sorry no pictures this time.

I made great use of my Sunday and got after-cure second coats of paint on all the engine bits, exhaust, and a few other pieces. I took apart the handlebar controls, cleaned them up and painted them. I got some bondo and filled in the emblem mounts on the tank and some other slight dents.

I also finally got around to getting all the bearings and bushings out of the wheel hubs and sent them and the rims off to get powder coated this morning. A nice semi-gloss black. Should have them back in a week. I also got the garage cleaned, and the cages vacuumed and washed!

In preparation of having the wheels back from powder coating, I went ahead and put a coat of aluminum gloss on the spokes.  The next day, Jen and I are sitting at Ducati Bike Night talking about the bike, and she tells me she wants the wheels black...  So tonight I got the spokes coated black.  The nipples will remain aluminum to give a little contrast.


And here are the semi-glossed rims and hubs.


I also got the carbs finished and back together.



Thanks for watching.  Here's another teaser of the engine.

Motor and wheel updates.

I got my 'dingleberry' in the mail and got the cylinders honed.


I am in the process of completing the motor tuning now.  I just have to do the timing and adjust the valves.  Here are a couple photos from assembly.  I replaced the old rings with new ones and its a good thing that I did.  The old ones didn't slip off the pistons but instead cracked.  Every one.  A little too brittle for my tastes.



And tonight, the wife and I relaced the wheels.  However, I can't true them without bearings...so I've just snugged the nipples and put the wheels in a dark corner for a while.




More to come! Thanks for looking.

I was going to wait to show these, but I can't keep you guys waiting.  So here are the pictures of the engine.

All I have left to do is sand the fins on head and do some detailing.



















Thanks for looking!

The seat-work has begun! After looking at the pictures myself, I do want to do a little more shaving here and there, but otherwise its ready for aluminum tape and fiberglass.

Started with a cardboard cutout of the general dimension.



Added foam florists blocks up to the height I wanted.



Started shaving the bulk off.


Sanding and more sanding.  But this stuff is remarkably easy to work with.






More to come. Thanks for looking!

Great build! I like your sense for details!

Thanks thewhip!

More seat progress:

I made some finishing touches on the foam, removed the cardboard and etched some holes so the seat would sit lower and a little tighter to the frame to make sure it was the height I wanted it, then began taping.



I grabbed some old tubing I had and taped it down as an outline for the seat-pan.  Hopefully this will make the pan fit snug once upholstered and add to the lines of the seat.




The whole seat is going to have a lip on it that comes down on the frame about an inch or so, almost even with the bottom lines on the tank.  I have also made it wide enough to utilize the stock hinges and seat lock, which is why I never shaved those off when prepping the frame.


Fiberglassing is next, though I don't know when I'll get to that.

So I am looking into bars for this bike, and I want it to be comfortable, not "fashionable".  So I am thinking of going with superbike bars, instead of clubmans, and retaining the stock footrests and levers.

Does anyone have experience with superbike bars who could give me a run down?
