Yamaha campus 60 YJ2 repairs part 4

[@davidroper3830]

Enjoyed your videos very much. My first bike was a 65 Yamaha 55cc, which I bought in 1966 before I had my license for $75 and took it apart many times for fun. Drove it to school and work rain or snow for a couple of years before replacing it with a Twin Jet 100. Many years and motorcycles later I am still riding. Thank you for your videos.

[@montana2strokeracer]

Thanks for the kind words my friend, my first bike was the Campus 60, I probably had it a couple years then moved on to the 100 also. I still enjoy riding once and awhile, but my real enjoyment is in the maintenance and machining to repair these bikes. I am just amazed at how many other guys and gals enjoy the same, I never would have thought there were that many folks that wanted to watch this kind of stuff. I remember having only 10 subscribers and thinking boy this isn't going anywhere, but here I am around 6500, still a small channel but still growing. I thank you for watching it is fun thing to do in my retirement, and I am so glad to see so many others out there still riding and wrenching on the old bikes.

Can’t wait to see it roll down the road Dale. Great video.

[@montana2strokeracer]

Well Dave it has rolled by now. Couple little problems, but she really runs out good, love the sound.

[@oldguysoldbikes]

If I had had one that was cutting out when the headlight was turned on, I may have gotten to point gap eventually, but I would have wasted a lot of time getting there. Thanks Dale.

[@montana2strokeracer]

I have had a few problems like this over the years. The first time I spent an insane amount of time trying to rewire the whole bike. I finally figured it out after a few days. Hard lesson remembered it ever since. Bet you would have figured it out right away.....your awesome in the electrical dept. That Navy training maybe?

[@steveh7823]

That bike brings back (distant) memories of my metallic orange/white Suzuki AC50 from around 1974. The two bikes are almost the same in many ways: the pressed 'T' steel frame, the inboard carb, the cylinder and head look the same, the upswept exhaust. A good trip down memory lane, thanks Dale, the lasting memory is that 4.5hp is just not enough!

[@montana2strokeracer]

Right on Steve, a lot of these bikes were very close in design, but boy they lacked power.

[@bigmurr725]

Thanks Dale . I remember that brake pedal being high on mine too . Dont forget the old 380, its calling for you Dale .

[@montana2strokeracer]

Thanks Murray, got it fixed I think, sounds like they were all like that. Haven't forgot about the 380, but it is on the back burner for now.....think it's going to be an expensive project.

[@retromechanicalengineer]

Dale, that sounds much sharper after having had the points cleaned and adjusted. What a great little bike. Best wishes, Dean.

[@montana2strokeracer]

It is a zippy little bike, sounds so great, and is cool on the road, except it is too small for this old man.

[@johnyoung3103]

Another great Video Dale: Back in the 80's before I got transferred out of SoCal I acquired a Suzuki rotary valve duel range trail bike, thing was amazing. My last dirt bike was a Can Am 250 6-speed, White Power 12 suspension, and Rotax rotary engine. Great desert bike but a little too long for single-track. Rotax perfected the rotary design, narrow cases, lightweight, and plenty of power. I never had to lay a wrench on it. No bore jobs, no jet changes, always ran great.

[@montana2strokeracer]

Hey John, never had the opportunity to ride a Can Am. I knew folks that rode them, and they loved them. I have heard of the awesome power of the Rotax. I was a certified mechanic for the Suzuki RE5's back in the 70's. They had an awesome powerband, and I loved to just listen to them idle.....liked that romping sound.

[@markaddy53]

great job dale sounds pretty sweet keep up the great work next video please

[@montana2strokeracer]

Thanks Mark, nice to see you here.

[@petermckee1061]

Sounding just great Dale. That's a sweet little bike. Looking forward to the test ride. The video reminded me, too, of the less than ideal quality of the Japanese workshop manuals of the era. Cheers, Peter.

[@montana2strokeracer]

You are so right Peter, the older manuals are terrible. This one I just acquired is one of the worse I have seen.

[@petermckee1061]

@@montana2strokeracer Yes, it looks to be a shocker! My Kawasaki F7 Bushwacker manual is a little better (but not much).

[@jamesbanjomanjohnson]

don't you just love it when a deal comes together, you got er Purin like a kitten,, sounds good,,, well done...

[@montana2strokeracer]

I like the sound also; it is just different than the late model 2 strokes. Thanks buddy.

[@markgaitan5107]

Here with a cup of coffee learning.

[@montana2strokeracer]

Awesome.

[@Kev-N42000]

I never liked the heal shifter either, I used to saw the heal part off on my old bikes, I never knew about lining up the pin and slide , now I do , cool thx

[@montana2strokeracer]

Yeah I think I did just that to mine in the 60's. Thanks for hanging out in the shop with me.

[@sidecarbod1441]

Dale, your going to look as cool as a cucumber on that bike! 🙂

[@montana2strokeracer]

It is a bit small, but cool it is. It really winds out for a small engine.

[@cainbeeping8480]

Very cool brother. That is a nice little bike. I’m ready to ride LOL.

[@montana2strokeracer]

Thanks Cain, and ride we did. Worked out some problems.....cool bike.

[@WilliamMcburney]

I loved my 60 and I saw that you have a 68 125 twin also ! I lost mine in a tragic fire.

[@montana2strokeracer]

Oh man these 60's bikes are so darn cool, and they do bring back the memories for us old bike guys. So sorry you lost your bike like that. We all sell bikes we wish we had not, but to lose one that way is depressing.

[@davidleland8729]

You've made some nice progress on the bike Dale! Looks and sounds great!

[@montana2strokeracer]

It is coming along nicely.

[@davidleland8729]

@@montana2strokeracer Have you had any luck in finding parts for the RM, Bighorn and the Elsinore?

[@davidleland8729]

​@@montana2strokeracerForgot to ask about the exhaust pipe on the DT1. Are you still planning to fabricate one or are you considering finding a down swept pipe from a YZ250 or TM250?

[@montana2strokeracer]

I have found some parts for all three, I sure there will be more to look for.

[@montana2strokeracer]

Yes, the plan is to fabricate, but plans around here are pretty fluid.

[@frankdillon6127]

Hi,Dale Frank here!

[@johnreid2837]

That’s the perfect bike for that.

[@jeffsilver4730]

Great series Dale. Thanks as always.

[@montana2strokeracer]

Thanks Jeff, I am enjoying it and I think a lot of folks are too. So far it's been well received.

[@rowlandcrew]

I think it was a great demo correlating the points opening with the dial indicator versus the timing light. I wish your camera was zoomed out a bit so we could see the dial indicator and the flywheel when you took out the backlash rotating the crank. The point (no pun intended) is an analogy to how things compare when timing a motoplat. maybe you have a motoplat you could demo. Question about piston skirt diameter versus top of piston diameter regarding piston slap. I would like to hear your observed ranges of diameter difference between top of piston and skirt. the idea is there is a company that will take your piston and thickness addition needed and put a coating on the skirt that will not only make up for wear but will also wear in safely to the point of ideal lubrication at minimal friction, all for about $50. Could be a good way to save alot of pistons and bores. The data needed is what ranges for piston taper are ideal on the old two strokes. thank you.

[@montana2strokeracer]

Yeah, my camera is not good for everything, I find myself lately using my phone camera on closeup stuff since the go pro has no focusing, it is wide angle only. Still learning the photography thing too, it's not easy for me. I do go over the difference in size of the pistons top to bottom in almost every boring video I have done. On two strokes it is .010 to .012 on most. Smaller at the top do to more intense heat (causing more expansion) from the combustion. There have many companies that have offered piston coatings over the years, the first I remember in the 70's was Teflon. It didn't last long and ruined a lot of engines when it flaked off. Many moons ago, we actually knurled piston skirts like they did with car engines back in the day. It really didn't work very long though and was more effective on 4 strokes than 2 strokes.

[@LarryJohnson-tc7xc]

I'm here Dale.

[@JamesMacfadyen-x2m]

I Dig all your vids dale.

[@montana2strokeracer]

Thanks James, sure appreciate you hanging out in the shop with me.

[@johnreid2837]

I think that would be a great bike to restore.

[@montana2strokeracer]

Yeah, John the plan is to tear it down, clean and paint. It is small but a really neat machine.

[@zerodown83]

What does one do if the timing doesn't line up? Just adjust the point gap since and that's it since the stator plate isn't adjustable?

[@montana2strokeracer]

Sure, thing Cody, this bike doesn't have an adjustable stator plate, so the only way to time it is by the point gap, using a feeler gauge or dial indicator. The timing light is really only for checking since you can't adjust them while the engine is running.

[@Studio64va]

Love channel. So much good info. Working on my 1968 yr2c. Just started. Can you explain what (red) charge light staying on means on the instrument gauge

[@montana2strokeracer]

Thank you, great bikes the YR2C, wish you the best with your project. If the red light is on the bike is not charging.

[@brentnearhood8874]

Thanks! Dale 🛵

[@montana2strokeracer]

Thank you, Brent, sure appreciate you stopping by.

[@leepeffer1304]

Kinda scary how many mistakes are in the Yamaha manuals. Big difference between .03mm and .30 mm and +/- .51 or .15. Kinda always took it for granted that every manual was as thorough as the early Honda manuals. One of the old timers told me when I was starting to learn about bikes that the point gap should always be 1/2 the spark plug gap, so I guess if it is too far off from that then something should stand out of wrong.

[@montana2strokeracer]

You are right there Lee. I had just acquired this manual and it was I think the worst I have seen. I noticed while editing the video, I didn't help things much either. I do that a lot......what comes out of my mouth is not the same thing I am thinking and doing. The price of getting older I suppose. The golden years are not all that great.
