I got their number and I'm going to call them in the next few days. Luckily I have my vacation time from work next week starting Tuesday so I'll have some time to take care of it and ride.

Well, I think I'm close to having the bike tagged and registered. I talked to a guy at the VIN office and he told me to send a fax of the bill of sale to him and he'd get it processed. He should be calling me back in a few days hopefully with good news.

On a side note, got started on the RD350 this week. The engine is painted and I need to finish polishing the sidecovers. I decided on something different for it. Most RD engines are all black but I wanted to paint the engine that cast iron color and polish the sides. It will look slick. Pulled the swingarm out and switched it with one that has the rear brake caliper mounts on it from a RD400. This will make it to where we can run the mag wheels. It is also two inches longer than stock so it'll will ride a little bit longer and lower. We're gonna try to have it all mocked up within the next few days and then tear it all back down again for paint. We're ditching pretty much everything unnecessary. The entire oiling system for the fuel is going away and we will just mix gas for it. We are also ditching the stock airbox in favor of some pods. Thinking about running a battery eliminator since the RD doesn't have an electric start and a battery just takes up space.. That will open up the entire area under the seat. The gauge cluster and dummy lights are all going out the door for some mini gauges and a hidden ignition switch. this bike will be clean and simple and totally mean. Probably out run my CB750. Gotta love those two strokes.

Yes, love those ol' 2 atrokes and RD's! My buddy had one, "in the day". It was fast!!

How 'bout some pics?

unitedguitar · « **Reply #78 on:** November 02, 2010, 10:21:49 PM »

Haven't gotten around to pics yet but if I remember I will take some tomorrow. Maybe even get some of the Trail 90.

OK. Tagging nightmare continues. The gentleman that I have been talking with at the VIN office informed me that the bike is actually a 73 CB750K. That is very odd considering that it had a VIN plate on it that said it was a 75. Doesn't make sense but I'll take it. He also informed me that the guy that I talked to last week for the inspection should have taken care of the situation right then and there and that my VIN number was totally valid. So, now since I waited too long today I get to wait until next Wednesday to go back and get it inspected.

I hear you on the tittle part. I bought a car off my mom a few years ago. I had a big headache with the tittle being lost with the company my mom had it financed through. I had to file for a lost tittle. Then the company sent me the original tittle, but because I had applied for a new tittle the original wasn't any good! It cost me time and money. I understand the frustration.

I haven't really done anything to the CB for a while but I have been working on the Yamaha RD with my friend. It is gonna be sweet. Here are some pics:

Here it is loaded up in the back of my pickup for the ride to its new home. Little did it know, it was about to be chopped up and torn down.

Unloaded and ready for some cleaning and dismembering.

Pics from after tear down and some modifications.

There isn't much left of the original bike. The frame, triple trees, swing arm bolt and bushings, headlight bucket and seat pan are all that are being used from the original setup. The tank came with it but it isn't the original one since it is orange and the rest of the painted parts were red. We got a set of mag wheels from what we were told was a rd400 but turned out that they were off of an xs400. Not really sure what the difference is. The swing arm, front forks and front and rear disc brakes are also from the 400. The 400 swing arm is about 2 inches longer than the 350 swing arm which gives it a pretty sweet look. We got some clip on handlebars and a dual disc master cylinder from mikesxs.com and a throttle assembly and grips from lowbrowcustoms.com. Why do we need a dual disc master cylinder you might ask? We are planning to run the front and rear brakes off of the same master cylinder using a splitting block and proportioning valve that we got from Jegs. The idea is nothing new since it has been done on trikes for handicapped individuals for years.

Right now we are chopping off all of the extraneous brackets and tabs on the frame and making a custom electronics pan that will house the electronics out of sight and keep the "triangle" completely bare. As soon as all the tabs are cut off and the new pan is welded on we can finish sanding the frame and get it painted.

Those Rd's are sweet bikes. I will never forget my first ride on one - wow was it a screamer!

unitedguitar · « **Reply #83 on:** November 09, 2010, 07:15:45 PM »

I think it'll be pretty quick. We're building it for someone else who rides a crotch rocket. Now he can have something quick and awesome looking.

Stev-o · « **Reply #84 on:** November 09, 2010, 07:31:33 PM »

cool, keep us posted.

unitedguitar · « **Reply #85 on:** November 10, 2010, 01:47:04 PM »

Good news! At least for me anyway. I got the 750 inspected today and I'm getting a tag tomorrow. After several weeks of the he said she said crap it is finally going to be legit.

For some reason I just keep going back to this design:

It has a classic feel without feeling like it is an outdated design. Plus there are so many color combinations that it could work with. Especially white on green.

If this were the option I go with it would be legend lime with a bright white graphic.

So many choices. Don't know what to do. If I only had several more bikes to do one of each design.

I think if I were going to use this stripe, I would turn it over, push it ahead so it rounds the front of the tank, then continue the bottom line all the way through the seat pan and end up with the same design, only reversed again, on the tail section. It would all tie together nicely and still be very simple in concept.

unitedguitar · « **Reply #87 on:** November 10, 2010, 06:41:07 PM »

This RD400 was the original inspiration for my bike. I was gonna do it up the same color and have a similar style seat. I always wanted to do different graphics on the tank. The idea for the tank graphics I designed came from the oil tank on the RD. I just turned them around the other way. I eventually decided not to go with the orange as it looks terrible on the CB and I think I have scratched the graphics altogether. Going to go for something clean and simple right now. Nvr2old, you idea is a good one and I might look into that for another build. I need ideas for something after the RD350 that is in the garage now.

Stev-o · « **Reply #88 on:** November 11, 2010, 04:37:42 AM »

I like the graghics on the side cover. Tank is a little busy for me, though.

unitedguitar · « **Reply #89 on:** November 13, 2010, 12:38:08 PM »

Finally got my tag yesterday. Now I just have to modify a tag bracket so I can mount the tag. Then it will be just a few small things before the bike is finished. Chain, tires, header wrap, new speedo and paint should be all that is left. Very exciting.

unitedguitar · « **Reply #90 on:** November 13, 2010, 01:24:07 PM »

Also, just got the RD back from the welder. Electronics tray welded in, gas lines for the oiling system removed and welded over and seat pan shortened two inches. This thing is gonna be killer. So for anyone keeping score, the rear wheel and tire sit two inches further back than stock and the seat is two inches shorter so it will have the appearance of being a total of four inches longer than normal. Totally awesome.

Took the CB out for a ride to Wal Mart last night. Needed some tape. I didn't have any gloves on and boy was it cold. My hands were bright red and hurt like no one's business. You can sure bet I bought some gloves when I got there.

unitedguitar · « **Reply #92 on:** January 22, 2011, 01:58:34 PM »

I guess it has been since December since I last posted here and I have actually done a thing or two to the bike. It was running way rich and got to the point where it would die as soon as I tried to take off on it. Bummer! I pondered the situation for a few days before I really had the time or drive to look at it and I decided to change out the spark plugs for a hotter set. Went from an 8 to a 7. Bingo! It runs a lot better now and no dying on take off.

Unfortunately that is not my only problem. I was out riding with my friend Bob (he just got a CB750) and my bike started to sputter. It died in the middle of main street. Embarrassing! I thought to myself it can't be the spark plugs again I just changed them. Well, it wasn't the spark plugs. It was far worse. The charging system is not charging the battery. We had to go get my pickup and load it in the back and haul it home. I was sad. I had the guy that set up my carburetors look at it and he said it definitely wasn't charging but he'd have to tear into it a little bit to get it figured out. So I need to take it to his shop sometime. If I want to ride it I just have to make sure I charge the battery before I go and don't get more than 5-10 miles from home.

Aside from that there hasn't been too many issues since I've been riding. I finally got my new tires put on. Bridgestone Spitfires front and rear. I also got a stainless steel hex head fastener kit for the engine. It looks a lot nicer than the phillips head fasteners that were on it. I haven't got them all switched over yet as some of the original ones are a little stubborn and like to strip out. I want to repaint the left side engine covers in the near future so any of the stripped ones can just be drilled out. I think there is only one or two on that side. The clutch side is a different story. All but two or three were stripped so that will take some doing to get them changed out with out taking the whole housing out.

unitedguitar · « **Reply #93 on:** March 29, 2011, 08:53:14 AM »

It has been a while. Since my last post the electrical issue has been resolved and now the bike runs well and charges the battery on its own. Unfortunately the engine side covers had to come off to fix the problem and they now leak like crazy. I was going to pull them to repaint them anyway so its not that big of a deal. Other than that and some other cosmetic work it is about done. Still can't decide on a paint color so it may be summer before it gets painted.

Now for some interesting stuff. I have a 75 750 Supersport sitting behind my garage. It was sitting outside without plugs in it before I got it and I'm sure it is locked up. I haven't actually tried to kick it over as the kicker is missing but chances are slim of it being ok. I have a guy that might buy it but if he doesn't I'm going to tear it down and build it up this summer. My question is will the cylinders from a K engine fit this. Outwardly they look like the same engine so I assume that it would work fine but I just want to make sure.

unitedguitar · « **Reply #94 on:** March 30, 2011, 01:26:47 PM »

So I broke one of my side covers the other day. Cracked the peg and entire corner right off the top of the electrical side one. I ordered a new set from Joe (Frankenstuff) and they are fantastic. Much better that the originals and they are primed already. I plan on filling in the emblem holes like my other set and then being extremely careful not to break them.

Still haven't got the CB painted and what's worse is it has a flat tire. I'm a little lazy when it comes to changing tires so it's been neglected. I have however been working on other projects. If anyone remembers a while back my buddy and I acquired a Yamaha RD 350 and we've been tinkering with that.

Here is a few shots of it to show how far it has come.

Right after buying it:

As it sits now:

The good news is that it does run and everything seems to be shaping up nicely. Just waiting on a few more parts to show up and then we'll be into the test and tune phase before its off to paint. We're also going to have the seat redone as it is a little bulky for the bike.

Hello all. I am currently taking a class on International Business and I need help for a project. Since a great deal of forum members are from outside of the United States, and have bought and sold internationally, I figured this would be a good place to start.

What I need are 10 people from at least 5 different countries (outside the US) to answer 2 questions about business. If you could help I would greatly appreciate it.

The questions are:

What do you think is the most difficult challenge for U.S. businesses that want to do business in your country?

What advice or suggestions do you have for American companies that want to do business in your country?

If you feel like you can help please pm me with your full name, country of residence, e-mail address and your answers.

Thanks in advance for your help.

Ben

Still not much progress on the CB. I did strip all the paint back down and redid all the body work and shot some fresh primer. My plan was to have it painted before the local car show last weekend but I just didn't give myself enough time. Regardless, the RD has been painted and I think it looks awesome. We're going for a 70's look and I think the gold and white really hit that theme.

Here's a pic with the CB in the background.

After getting my 750 all together and then in primer I haven't really touched it. My buddy and I both took our 750's to a show back in the fall and they garnered a lot of attention. As I was riding it home from the show I toasted my points. Not the greatest thing to have happen driving down the road. I put some new points in it but never really got it tuned back in. Since then my buddy's 750 started having battery issues and he now has my battery in his bike. So, my new plans are to revamp a few things over the next year or so on my bike. The plan as it stands is to get it salt ready. We're going to take it to Bonneville next year and run it during speed week. Hopefully this will give me more to post about as several things will have to be done to bring it to safety spec. This will of course all have to wait to get started until my other ride is done. Over the past three months I have been slowly putting together a new car for myself. It is a 1963 Chevrolet Chevy II, otherwise known to most as a Nova. Here are some pics of that progress.

This is what it looked like when it rolled in on four flat tires and no engine.

I spent the first few weeks putting together this engine for it. The engine came to me as a greasy nasty block with the lower rotating assembly installed but nothing else.

Here it is when we got the engine and transmission in.

Some styling graphics.

New chrome.

More new chrome.

The completed running engine.

After it drove under its own power for the first time in over ten years.

Nice project. What size is that motor, 265?
