I just wanted to let you know how much I enjoy your channel. I grew up in the 70's riding two-stroke Yamaha's. I had a 1974 DT 100 and a 1972 LT2 MX. They were such fun bikes to ride, it was a great period in motorcycling and I was fortunate to experience it. Watching you rebuild these vintage machines really takes me back. Thank you for sharing your work on youtube.
I was growing up here in the UK and it really did seem like an exciting time for motorcycling. They were everywhere and new innovations seemed to be happening almost constantly.
@@retromechanicalengineer nice to see the nostalgia creating a greater appreciation for the technology/innovation. Seems like there is a growing vintage riding/racing community here in America. People fix up old bikes and race at Daytona & other events in a vintage class. It’s not just for looks
@@vinnyvinson the same seems to be happening here. There is definitely a younger generation that don't just want to look at older bikes, they want to race them and use them as intended. It's great to see.
I had a similar issue happen to my TC90 back in the day. The Suzuki dealership had a really good shop and didn't have any issues after they bored the cylinder and replaced the piston. I think you shouldn't have any problems doing the same.
Hey David, Yes I think your right, just not sure what cause the problem to start with. Owner said he got the bike without an aircleaner, I think that explains the problem.
Any thoughts on Ball Hone sizing. What I mean is how much bigger should the ball hone be than the bore which I understand is considerably more important with 2 stroke cylinders than with 4 strokes. Thanks as always for taking the time to put these great videos online, they are GREATLY appreciated.
Hey Alex, I have heard somewhere how much oversize they should be for preload, can't remember where. I think about 1/2 inch is enough. You just need some pressure against the cylinder walls. The great thing about the ball hone is that it takes care of chamfering ports too.
In my experience, Suzuki 125 motors can only run at a max of 0.006" oversize before the skirt breaks off. (on a 56mm bore) The 90, being a smaller bore (47.5mm) could conceivably go to 0.010" over but that would be maximum before things start breaking due to piston slap. The optical illusion of the holesaw going through torque plate (around 33 min) made me feel a bit nauseous 🙄
Yes, I understand, I just don't like any of them very loose. I like to set up tight and do a slow breakin with an overabundance of oil. They just tend to last longer this way. Yes I saw it too, looked like the stem was turning one way and the cutter the other. Very weird.
I am slowing down on outside work for the summer, but if you haven't got it taken care of by fall, or can wait till then, probably can help you out. Let me know. dsweger@bresnan.net

great job dale great to see the new mill doing its stuff keep up the good work
Its really fun and exciting. So much smoother to operate.
It makes a world of difference to have those great machines. Good job brother.
Yes it makes it doable and fun.
Great video Dale!
Thanks Troy, sure appreciate you taking the time to watch.

The 70’s really was a golden era for bikes.

@@vinnyvinson I'll have a look
Nice attachment tool for cylinder boring 👍
Thank you, it really does work well, just time consuming to make.
Great fixture Dale. I like it because it puts the barrel in compression as it would be when fitted.
Idea noted!
Best wishes, Dean.
These fixtures do work well, just like a torque plate on a car engine when they are being bored and honed.
I love how you teach it
Thank you, sure appreciate the kind words. Thanks for watchin.
Great videos this week Dale, thanks!
Thanks Jeff got lots of fun things going at one time. Thanks for watchin

Well now that you have the adaptor I have a TC 90.....

I have a steel slate motorized bicycle motor it’s 49 mm do you think it can be bored to 52
Not real sure without looking at the sleeve size, do they make a 52mm piston for it.
Hey brother
Hey buddy, glad you made it.
here, barely.
But your here, that's the main thing.
