- In this video I remove the top end on the RT2 MX. Then I remove the clutch cover and install kick starter parts and the RH crankshaft seal. Then upon reassembly I find a stripped thread and install a Heli coil.
I am always impressed that Dale's suburban garage is way better equipped than most pro workshops. A major investment there!
Thanks Steve, it has always been my interest along with the bikes, I have been collecting tools and machines for the better part of my life. Just a little at a time!
Great to see you tearing into the 360 and that you have all the parts for the kick starter. I've had an RT3 for over 15 years and haven't even tried to start it yet. "Ran when parked".
Hey Doug, it looks like I have everything. Not sure how the kicker is going to clear the frame though. I would probably have a heart attack push starting this thing now. Kicker is the only way. Oh yeah, the old "ran when parked" saying. You need to proof it out my friend. Go see if it will run. They are still fun, but scary to start. LOL
Thanks Dale. Lovely work as usual and I'm looking forward to progress on this bike. The right side gear shift surprises me. Makes me think of my old Beezer and Trumpy back in the day.
Cheers, Peter.
Thanks, buddy, yes Yamaha made provisions for the right-side shift on all the 250/360 models, does require some drilling, but pretty easy to do, you just pull the shaft through the other side and put the clip in another position. Can't remember how many years it was available. If you look at the outside of the side case adjacent to the Kickstarter you will see a little bump, its located for you on the inside so all you have to do is drill through.
@@montana2strokeracer Cheers, Dale. Had no idea.
All in all that engine looks to be in pretty good shape. Nice work Dale!
Yeah, I think so Dave, like I said it doesn't have a lot of miles, just hard one's going in a circle.
Dale you make these repairs look so easy ;-)
Thank you so much, most of this stuff is not too hard to do. You just have to get in there and do it.
I watched a couple of flat track races and it definitely is a sport for the much younger generation.
You bet, time to clean this one up and let someone else enjoy it.
You're fantastic Dale, thanks for sharing your top-notch talent.
Thank you Jeff.
I just love that little oil shield.Pool little slide hammer that's cool
Thanks Richard, homemade stuff works the best.
Thanks Dale , Its been a long time since I worked on a 360 . I thought for a race motor they would have put in straight cut gears . Oh well keep up the great work Dale , we will be watching .
Murray
Yeah, you would have thought so. I don't think I had ever been in the side cover on this one. Not sure on the 250/360 mx bikes but the 125/175 had straight cut gears available back in the day, they are still in the parts manual, but never have seen any in the wild.
Great quality of work as usual Dale. I'm looking forward to your progress on this one.
Best wishes, Dean.
Thanks Dean, this one is super cool old racing technology, think they are still pretty competitive, actually they are faster than the 4 strokes they use now.
Great job Dale.🤟
Man I love your show thank you Dale.
Thank you, Joe, hope to see ya back often.
Dale you need a pit crew to start those and they are hard to come by , the kick starter will be great , hope you get to ride it again !
You are so right John. I just don't what to get hurt starting it, LOL
That will take some getting used to. Shifter on the wrong side. Good job brother
Yeah, shifter and brake on the right side, steel shoe on the left foot. So, you can slide and still shift and brake.
nice job as always dale looks a pretty good engine this no trauma on it next video please
Yeah, this one looks pretty good, just worn.
Good morning Dale.
Hey Larry, good to see you back.
I like the fancy piston pin puller and guide pin thingy puller , I made my own piston pin remover out of a c clamp a welder and a wrench but the one you got is much better , I hope I can get you to bore my RZ350 cylinders someday
Yeah, I have a homemade one too, that I used for years, one day it didn't fit one I was working on, decided to buy one of these. Works well.
Thanks for posting
You are welcome, will be more of this series coming.
You always scare me with the impact driver on the clutch screws....lol
Don't worry Evan, it is a light tap, I have never broken a standoff, or stripped a thread. This is how I was instructed in Yamaha dealer school, never failed me. I can see though if you get overly zealous it could be a disaster.
Another master class Dale. Did you see Mustie1 was working on a DT360 today?
Thanks Dave, yes, I saw but have not watched yet, he did a CT175 a couple years back.
Hot setup. I have been unimpressed with the newer silicon formulations. Why not put something like yamabond around the seal and on the cover gasket, and low strength loctite on the crank nut? Nice to seem someone working on the cool stuff. thanks
Hey, Rowland, you could do all of that stuff, I have always had good luck with the black rtv. The crank and clutch nut have never been an issue loosing up, so I just don't see the need. But if you're having a problem.....loctite would be the answer.
😎👌
Hey buddy this just now came in.
Wow, guess the bell icon is out to lunch!
@@montana2strokeracer not sure what happened.
You certainly have them 2 strokes down, don't bother with 4 strokes, twice the parts, twice the weight, half the power.
I would like to find a Honda Super 90, or a SL100 or 125. They are cool too.
@@montana2strokeracer I always lusted for an XR200 but alas I have acquired 2 Yamaha XT225's that are the same weight and have 20 HP and a mono-shock. The seat height is low enough for me to get my tired leg over and they seem to run forever. The trick is to swap on a set of YZ85 cartridge forks in search of plush. something my old body is in search of.
Loving your work as ever Dale.
Have you got any info on that engine jig ?
Thanks Vincent, it's a lot of fun and brings back lots of memories. The engine holder is an OTC 7020, it's really an automotive tool, but it works great for bikes too. Try to find a used one, the new ones are really pricey I see.
Hi guys, lets get to work!
Hey Frank
Just curious Dale, is that huge lock washer standard on the 360 or was that something they put on for racing?
No Jack it should be a belville washer. This was done for racing, it has held all these years, so I thought I would put it back in.
Just a quick question for you Dale, Why were the 650 Yamaha's so difficult to start up? Seems like alot of people out there have had the same issue.
Oh Dave you have asked the wrong guy, I think the only thing I have done to a 650 is change the points.
Wondering about the helicoil size. Thread info, drill size. Assuming its M6x1.0
Yes, it was M6 x 1.0, You need the HELICOIL kit, it comes with the correct drill and tap. They are not common tools; they are specific for HELICOIL.
Dale I have a question what do you call the tool you used to put the clutch screws in with ( approx min 34 ). I broke mine and I am looking for a new one, when I go to the tool shop nobody knows what I am talking about. Any help would be appreciated.
That's a no. 2 Phillips size driver bit normally you'd buy in a multi set pack from your local hardware supplier. The sets have all different style patterns, hex, Phillips, flat, 12 point. Look out foe them.
Thats a hammer impact driver, they are easy to find, just look on about any motorcycle supplier. If you're working on these Jap bikes, be sure to get you some JIS bits, they look like Phillips bits but are different.
Dale, I would be interested in buying this bike. Not sure how to reach you other than here. Steve
Hi, you can contact me at dsweger@bresnan.net
Don't remember a right side shifter on a Yamaha ?
I'm not sure all the years that had it, probably at least 72/73. All bikes had it built in, but you had to drill the hole in the clutch cover, but it is already located for you on the inside, then you just pull the shaft through and install the clip in the inner position put a seal in and you are ready to flat track. If you will look at the clutch cover just below the kickstarter you will see a little round bump, you can drill through from the inside. It does take machine work to do it.
@@montana2strokeracer I can remember a friends father motocross raced a early 70s Husqvarna that was convertible left or right shift , rode it once about hurt myself trying to find the right side rear brake that was on the left side that was the only bike I ever rode like that
