Tie wire on tapered primary mounting stud??

I was just thinkingabout part of a recent post where our esteemed member Hobot & a few others said they tie wired the stator leads to the inside primary covers mounting stud to keep them safe etc. Now while this sounds like a good idea the casting (at least on mine) is tappered so no matter how tight you get the tie it will allways slip off with the vibration of normal use won't it??? What's the thought here folks, I makes for a bad idea to me since you would end up with a loose tie and then it has the chance of getting snagged by the chain. Yes ??? No ???

My wires are so old and stiff you couldn't move them over that far. Now if your wires are new and fresh and loose... But I've never had any trouble with them in 4 decades. How many people have had the chain cut the wires? Probably a few because they left too much wire in the primary.

Its just an optional peace of mind detail but if hobot and others can figure it out ...

Very good observation. Like ALL tips, internet or otherwise, always run it through your common sense/bullshit screen on the way by. Yes, it's tapers, but the stator is bolted on the end. The tie wrap, if it were to get loose, would only slide down a bit and stay there. No drama. Like already mentioned, the hardened wire needs no support, in my case. There is LOTS of valuable, time saving, frustration saving, pattern failure fixing, better idea improving, reliability enhancing, safety and longevity tips being shared. The key is to be able to seperate the wheat from the chaff. I am very grateful to have a resource such as this. For axample, I have have a VW Jetta TDI that I bought new, and now has 403,000 miles, many thanks to http://www.TDIClub.com tech info for saving me time, money and aggrevation. OTOH, the 1973 Yamaha TX750 I restored has little to no info, and it's a different challenge.
Use a tie wrap if it makes you feel good, don't if it doesn't. :lol:

I felt better with the tie wrap, what with the tugging while routing the leads on the outside, Snug tie with pliers then clip and after a while it hardens up in place like the wire insulation.

It hardens up to the trained shape eventually from heat. TX 750 for 3 years, no probs with the counter-rotating balances issue.

The two balancer shafts rotate the same direction, same as the crankshaft. Turns out, the chain that drives them stretches, (surprise) originally with no way to adjust. Retrofit and then 1974 model year have provisions to adjust the chain. Was yours a '74?

Yes , I believe she was a 74 Yamahaha TX 750. An orangy-gold colour.No issues and good service to me.Bought for a thousand against my parent's well-wishes and sold to a friend for 800.He had the rear torsion bar to hub snap on him and he welded that up. Lost contact over the years.

like this? 1973 colors..

I remember removing the balance shaft on a friends TX750 when it was near new,

Yes, that's my old baby ! She never had an oil cooler also that under the crankcase "fix" kit was never installed, this is the first time viewing it.

The oil cooler was one of many attempts to stop the engines from failing... that wasn't it. The mystery was finally solved by a savvy racer, he sawed a window in the side of the oil tank, made a lexan window and observed the oil totally foamed. Finally found the lower balance shaft was whipping the puddle of scavenge oil in the sump into foam, the 2" tall sump extension did the trick by lowering that puddle away from the spinning balance weight.

Thankyou for clarifying this as for 3 years I drove her about waiting for the vibration to increase but she was smooth as silk and never used oil. I do miss her but the 800 went towards my first $1200 Norton.

Story goes, many that were driven gently, as in no sustained high speed operation, hung together OK.
