3.22.25. Another entertaining video by Tom! Lol. Seriously you work on other peoples bikes like you own them❗️ you are so thorough in your methods and how you craft solutions🎯 Every time I get a notification of a video you post, I immediately start watching it. You don’t put forth any half baked®️attempts on repairing, and I like that, I’m a little bit like that myself. That’s why I probably don’t think that your videos are too long.
Hey Tom I just purchased the 2002 police motorcycle...I started watching your video and realized it was the same bike. I'm thankful for your knowledge and attention to detail. Love the bike. Hopefully we could catch up sometime and chat. God bless you and your family Amen 🙏🏼
I believe it was you that emailed me? Soon as you did, I scanned Marketplace and saw it was for sale in Venice (FL) I think? For about .3 seconds I considered buying it back. Maybe .2 seconds. lol.... Contact me anytime I'll fill you in on it, I believe I emailed you back and offered the same, but I never received a reply. motorestofl@gmail.com
I have had the same Z1R Kawasaki since 1986...and always done my own engine work...now making 124 rwhp using Moriwaki parts. But I have learned so much from your videos...they are Excellent. Thank you very much from Cumberland England. Subscribed.
Very good and informative video. Thanks for all that work You put onto making it for us to enjoy! I wonder why new seats cost so much. I've seen it done a couple of times, and it didn't seem like that much trouble? Stay healthy and watch Your fingers at the mill...😝
Glad to hear you & the wife are feeling much better. You did a great job on repeating the head getting it back up & running. I have been wrenching k restoring Kawi triples & big fours since the early 70’d & know just how much work & effort it takes for you to do this worn on these old classic bikes that have mult issues along with mult people screwing them up prior to you working on them. Keep up the good work & great videos you put out I enjoy watching. Btw,have you got any more of the 26mm Mikuni carb holders you Ii mfg’d avail for sale? If yes I’d like to buy one so please leave contact info so I can buy it from you. Thanks,scott
Glad you are both feeling better, absolutely great video. engineering and bikes. Great content and info didn't mind the length of the video in the slightest. It's brilliant that you managed to solve the problem and save the engine. Can't wait for your next video. Thanks for sharing
Hey Tom I'm about to strip and rebuild a 76 KZ900 engine. On the cam cap bolts it sounds like the thread is a common point of failure, I see you torqued them up lower than factory spec, do you think it would be a good idea for me to do this on mine to not run that risk of stripping them and maybe put a dab of thread lock on them? Glad you are better keep the videos coming I really enjoy them!
I wish I could say for sure, but truthfully, I don't know. I am guessing here based upon some experience and the fact that typically, an M6 bolt takes about 6.5 ft lbs of torque for a 1.0mm thread pitch and 95 inch lbs (the low side of the service data) is nearly 8 ft lbs. I'm going with it and did recheck them after two heat cycles, they were still tight. Like I said, wish I could tell you for sure but I can't.
The measurement error occurred because the valve was cut 5 times not once. And since the total error was 4 thousands, each of the 5 cuts was .004/5 = 0.0008 or 8 ten thousands. There are other possibilities but the 8 ten thousands per cut is the most likely. To test it simply take a scrap valve and cut it in as few cuts as possible and measure for error then cut again using many cuts and measure the (compounded) error.
I think I might know who screwed up the original valve guide install. Had the same issue and same explanation on one of my heads. “That happens sometimes, don’t worry about it.”
The next guy that services this head, if not you, better be aware of everything you have done here, or this is going to turn into a nightmare for everyone involved. You really should have convinced the customer to open his wallet, let the moths fly out, and install new valve seats. After all, that was the primary issue. The seats had been cut too deep.
We tried. Nobody local could do it. I spent a lot of time searching. Then I talked to APE and they deal with this all the time. I couldn’t find even a place to ship it besides APE. I wanted to but they basically talked me out of it with the cut down keepers. This customer has owned this bike since 1980. It ain’t going anywhere. But I agree wholeheartedly the best solution would have been new seats.
There could never be a too long video from you. Actually I wish you would show more work, at the same time make your videos shorter. Does that make any sense?
@@MotoRestoFL There's a lot of detail that you do off camera. There are people that would love to know how you did what you did off camera, me included. Does this help.

Glad to see you up and errrr "running" again . Hoping your well .missed your contents
I'm happy to see you took my advice and didn't die when you were sick.
I was afraid you'd be mad if I did.
@@MotoRestoFL We could never be mad at Motorcycle Grandpa.

Wasn’t available at the time.
Great work, glad you on the mend...
yess! you said it the valveseats were ground tooo deep .that sets all measures out !
Very good and informative video. Thanks for all that work You put onto making it for us to enjoy!
I wonder why new seats cost so much. I've seen it done a couple of times, and it didn't seem like that much trouble? Stay healthy and watch Your fingers at the mill...😝
Love your videos BECAUSE of all the detail, you have a great way of getting the true engineering side across, quality of jokes not so good... :)

Hope your health is better
We’re better. My back is an issue but the chiropractor is helping. Thanks.

Much appreciated!
good to see you're back, I was wondering where you've been! Always look forward to your videos.
God bless you I hope you and your family stay healthy, I love your videos.

Those valve guides mean she's been in ""Bad Hands". !!!!
You hurt my tiny brain.
'Protrusion' sounds a little more professional than "stick-out".
Don’t belittle yourself, nitpicking about terminology is below you.
I think I might know who screwed up the original valve guide install. Had the same issue and same explanation on one of my heads. “That happens sometimes, don’t worry about it.”
I’d have left it if the customer didn’t want it done but he did. I hear from him periodically, says it still runs great.
U don't no what u r buying 2nd hand do u some times alot of trouble jobs well done hopefully better than new 😂😮😊
Ain’t mine. This bike has had only one owner since 1980.

aftermarket camshafts!!! no wonder got problems!
Why people modify a perfectly good engine design is beyond me.

Nope. I'm dense. Do explain. Thanks.
