Well, new to Triumphs and gang tackled a bunch of stuff. Ended up with a ton of parts and now need to weed it out. Trying to build one bike and can't decide what to do. Have a 73 OIF roller and all this stuff. Going the keep one and sell the rest to fund the project. Problem is I don't know way I have or what it's worth.
I know, great problem to have. But now Barber is coming up and it will be my first time. I would like to at least have some base for trading. I would look over the for sale exchange but have not been cleared yet.
I could only have 10 pics in the thread but have over 20 pics...
#6 should have a 5-speed gearbox.It would have a 30mm timing-side main bearing.The rotor shaft will be longer than earlier engines,so the primary case is deeper to fit.If it's a T140 or TR7,the conrods will be different length to 650 engines and have bigger gudgeon pins.
#1 may or may not have 5-speed.It would have 1-1/8" timing-side mainshaft,like the other earlier engines.
Heavy duty conrods were fitted to 650 engines from eng. no. DU 47006,so I wouldn't use the rods from the 2 early T120R engines (#10 and #11).They will also have light flywheels,which you may not like.They won't have nitrided camshafts either.Nitriding commenced at eng. no. DU 87105.
I'd pull out the crankshafts,and if any pass crack-test,I would NITRIDE a good one and preferably one that's not re-ground.
Rickman/Weslake/Nourish 8-valve heads and barrels will give you more cubes and more power too,but aren't cheap.Most of the cylinder heads and rocker boxes shown won't fit the OIF frame.The ones you want have locating roll-pins between head and rockers,and head-steady studs on the rocker box.
That's quite a haul! before you sell stuff, cleaning it would improve your chances of a higher price. Not drastic, but maybe Gunk off the worst encrustations.
If you`re going to base it on a `73, get the spares book.
There isn`t one for the 650`s, so you have to juggle between the `72 650 and the `73 750.
The obvious engine difference is the number of head/barrel bolts, 9 for the 650 and 10 for the 750.
Also you need to decide on a Bonnie (twin carbs) or a Tiger (single carb).
These `V` models have a 5-speed box.
`73`s have a front disc brake and a triplex primary, push-in pipes and the long, finned rocker covers. (4 screws...later 6 screws).
Depending on when it was made, it may have the leaf-spring G/B camplate selector or (preferably) the plunger.
The 650 V`s are basically 750`s apart from the engine.
Yep, it's approaching the same size as what Mid-O has shrunk to over the last few years since the AMA/AHRMA split, and is sure to eclipse it with all the racing PLUS the museum, various bike shows, and auction...
I am thick sometimes. Love the adventure of being new but the lack of knowledge is tough. Must have been too excited on the parts lot. Motor #2 matches the OIF and is a 71 per serial number check.
Yes, I am talking about the Barber Festival next week. Like to pick up what I need and fund the purchases with the rest of the parts. Anything super valuable in the bunch? Maybe sell the whole lot and just by a done bike. Looking at both directions.
Thinking I might have bitten off more than I can crew...LOL. What's the value of the whole lot of parts? Enough to get a complete bike?
First, I recognize that this is the kind of post that might put some folks off because:
There are ways to check for major issues, including during routine maintenance (eg flakes in the oil)
Opening up the bike is a good opportunity to learn more about it
The sound in videos is going to be...
Hi, So I've nearly reached the total the end of my strip down of my 71 T120 right down to separating the crank cases,sludge trap etc.I know nothing of possible improvements and must do's on the re-build. Any chance of some definitely do this pointers please. Thanks
When I step on the rear brake pedal the engine stops.
Tomorrow I will start tracing down the wiring.
I suspect, and hope, it is at the switch.
Has anyone experienced this problem? Maybe I can cut to the chase.
Thank you,
Steve
Good afternoon to all.
The last time I rode the cub it kept cutting out. It would kick start again and then after a few miles cut out again. So I have now over the last few weeks changed all the electric connections to soldered ones as opposed to bullet type. I have also stripped down the fuel...
Hi all,
Finally a warm enough day here for me to fire up the 77 bonnie for the first time in a few months and try out some of the repairs and tweaks I've done. After a few kicks, bike fired up, ran very rough, then died. I did a few quick tests and determined the left cylinder is not firing. I...
