I couldn't have chosen wisely without the advice, and experience gleaned from you all here. I would have bought any shaved down, past it's useful life, piece of crapola. Mainly I learned that there is a reason for two valves, and three guides in most of the eBay heads.
There is something to be said for learning. No matter what I said in high school.
Holy Mackerel... My bike is making me money already!!! I LOVE Triumphs!
i just got lucky on the timing for this. I must have "ask seller a question" 30 people in the past 2 months.
Trying to find late T140 rocker innards is quite another story. I found a fella with new shafts but no appropriate rocker arms yet.
I also found a common thread in sellers there (Fleabay). The ones that claim to be shops, parting out engines, and stating a specific year (on rockers) are mostly wrong on the claim. When you contact them for verification they will not reply, and hold out for another buyer. I have found MANY T140 complete boxes that claim to be 76/77/78/80, and they are all the older rockers (early 70's) with no oil reliefs in the arms. I've actually begun to report sellers that do not reply in the time stated.
Just to finish the thought... My plan is to use the later innards (76/77/78), and the early boxes (67/68/69/70) as recommended here on the forum, to take advantage of the improved oil delivery. I thought I liked the newer boxes but decided I like the old style better.
I'll consider your offer Grand Paul... Done considering, not! Thanks tho :-}
the newer boxes require you to preplan your headbolts and head steadies as well
Into the distance a ribbon of black Stretched to the point of no turning back A flight of fancy on a windswept field Standing alone my senses reeled A fatal attraction is holding me fast how How can I escape this irresistible grasp?
Yes sir. I've been advised of this. I did consider the newer boxes, and the associated hardware but I have since changed my mind, and prefer the look of the older boxes.
I will be using the original style (1967 - 1970) boxes with the newer style (1976 - 1979) shafts, and rockers. In fact I am strongly considering modifying the rockers further to accept the drilled ball ends, and drilling thru the later rockers to deliver oil directly from the grooved shafts.
Here comes the sacrilege... I'll be running the Morgo rotary, and a pressurized rocker system. My pressure relief will be in the remote filter rather than on the cases, and all the oil lines will be hard plumbed (heat sink-ed stainless) with shock relief fittings.
Over kill? Maybe... so are (w) + rated tires on a street bike. If nothing else it will be a fun build.
...hello Zombie, 79 and up have different valve adjusters with Allen heads; in my opinion, easier and nicer. You cannot put these ones in previous (late too) threads.
.You almost robbed the guy ha ha. I do not remember right now but I paid between 150-240 there in USA, for 76 head then another 450 to send it to W White to put new valves, guides etc. Then International shipping and customs expensive taxes.; so around 1100 or more.
I just got lucky Reverb. Right auction (12 bidders), and a pant load of nervous as the seconds ticked away. $151.51 was my "Max Bid". I think it was the fact that the head was left as it was pulled, and the rest of the bidders (that night) were fighting over the shinny clean (shaved, and stripped) heads.
I do get the Allen head adjustments are nicer. They are easier to grab at the angle you need. Also the later boxes are easier to gain access with any tool of choice. I've come to grips with this. It's a visual thing, and trade off. I'm certain I will find a way to deal/live with this choice.
As far as what it will cost when the head is done as I want??? whatever... Most likely very close to what you spent. I'll burn that bridge after I cross it. Seeing smoke in the rear views tells me where not to go again.
You know the drill. We only live once (that we can recall).
