1973 CB175 Project - First Build "Anna"

Be very careful not to eff up your cam gear when taking the chain off. Your best bet is to use a chain breaker or cut/grind it down where its not touching anything.
 
Ok, so now I got the head pulled off and got a good look at the pistons and valves. Aside from the carbon buildup which I will clean off, I do not see any glaring issues. I'll pull the jugs as well to inspect the cylinder bores and rings. Also not the two cool things I picked up from Harbor Freight...an engine stand for $49 and a fine abrasive ball for the drill..which does a nice job on the stator cover!

Von, I tapped the master link clip off with a small screwdriver and rubber mallet. The clip flew off into space but I didn't damage anything. Thanks for the tip though!
 
Another update! I was just telling my wife it seems like projects such as these require about half the time learning how to do something or modifying something to make it work, such as the engine stand mod for the motor as seen below. I roughed out a simple bolt on solution for getting the engine off the plywood stand and onto my HF engine stand. Works pretty well, the only problem is the right side cover cannot be removed while on the stand. I'll pull it back off to remove the side covers when it comes time to clean those up.

Also, a friend of mine is also into refurbishing bikes. He got a blast cabinet and is sourcing an oven for powdercoating parts. I offered to bring my own paint and blast media and he'll be helping me get some of that work done on the smaller bits and pieces. This should save a few bucks!!

Anyway, here's the bracket and the engine mounted...

So, I have decided to keep my stock tank and paint scheme but the original one on the bike had a horrible seal job done to it. It looks like it was sealed over top of some surface rust. So, I called around to see if the lining can be stripped out and the rust removed then relined. Some advice I had seen was that radiator shops do that kind of thing all the time, so I called my local business. They quoted around $200 to clean it and reseal it. But, to remove the lining they had to bake it out in an oven and this would have turned the external original paint job to ash. Well, I found this gem online from a dealer that had it sitting in their warehouse for 20 years. I scored this sucker for $178! NOS, and exactly the paint job for my model year 1973 K7.

So if anyone is interested in my original tank and is willing to clean it out/repaint it, ect..let me know.

So, on to the pics..

One of the benefits at working at a large manufacturing business is the access to sweet tools such as this tri-mic. In addition our service shop bay next to my office has a nice aqueous cleaning tub that works wonders at cleaning large parts. After a soak and scrub I took some measurements.

I'll have to compare the measurements to the shop manual but the cylinders will probably need to be honed while I have it apart. I'll be checking the piston dimensions and rings next.

Wicked score on that tank. Keep up the nice work. I just got a 175 sloper motor that I wanna drop in my 160. Its all in pieces, & Ive never done motor work. Excited to put her back together

What year is that sloper? Do you have a build thread yet with pics?

I've never done engine work before on my own which is one of the reasons I got a project bike. It's been frustrating at times but a very fun and rewarding experience overall. I figure if I follow instructions and can read a shop manual it shouldn't be that difficult!
 
I think a 68 motor. I had a thread on here but the pics got deleted. The build I have is a vert like yours. Went more bobber style with it. Pic is where it sits now. Motor work freaks me out, Imagine rebuilding & forgetting to put one spring or something in the wrong place. Motor no likey. So finicky. But yes get a manual & tear into it. 175 verts are pretty common parts wise.

That tank rules! Where did you find it at?

I'm building a CL175 right now. I'll be watching your thread!
 
Ok, a long time has passed since I have done anything on this project. This year rolled along and I got antsy to get a bike to ride while I worked on this project. When my dad had restored the headlight he asked for another thing to work on so I gave him the wheels. Well, months passed and I should have known better than to give my dad these things without any guidelines budget wise. So, after having them for months and sourcing parts, etc..here are the final results. New tires, rims, polished stainless spokes, chromed brake mechanism, polished hubs and NOS sprocket. He just upped the level of this build a whole notch! At this point I'm just going to give him the whole damn bike! LOL
