Oh, something is telling me to stay away from this one. It has been a long time since I messed with a vertical twin triumph.

The first thing to do is to check the points and timing. Check and reset the points first. Usually if no one has moved the plate, the timing comes right back into specs with the points gapped correctly. But, just to be on the safe side, check the timing once you get the points right.

Next is the carbs. Hopefully you aren't still running the original Amal carbs. The Bonneville had twin carbs and they need to be balanced pretty well. You need a carb syncronizing tool to do this with. It works off either manifold vacuum or air velocity through the venturi. You can play with the idle mixture screws and idle speed screws and maybe get it close. But, unless you are somewhat familiar with any of this advice, I'd look for someone with some experience to help you with the job. If you get the timing too far off or the carbs too lean, the Bonnevilles were terrible about burning pistons. We don't want that do we now. Good Luck, Steve

they two comments above me are right, you have two sets of fuses on your bike. one set is either near your handle bars or under your seat. the other set is basicaly relays under the back left of your bike, there you will find one regular fuse next to the relays which is for your ignition and starter. I would check that fuse almost certain it poped.

Did you use a Typanium Recitifier? There should be no problems unless it is a used one. All the new ones I havew used just "bolt on" .. there are 5 wires. Check to see if you don't have a grounded wire some where.. try it with the head light off.. I usually wire my bikes to start with no head light with a 3 way switch.. once running I can then turn the light on. Go through an check all your wires again, you might just have a bad connection somewhere.. here is an excellent site .. Jim http://www.raskcycle.com/techtip/webdoc16.html

charge the battery up and use jumper leads from a car ,if problem persists then its new starter motor ,because it could be the bendix pinion from your description ,but it might just be the battery not holding enough reserve amperage power to turn the starter motor hence the car jump start .

Oh, it's been a long time since I've messed with a pre-unit Triumph. Best as I can remember, the transmission was adjustable on it's mount on the frame. You loosened the inner primary bolts and the transmission mounting bolts. There was an adjuster mounted on the frame behind the transmission, I think.

I hope this helps. It's been a LONG time since I've seen one of those and I'm an OLD man with a questionable memory.

Good Luck
Steve

screwing the jets in makes it rich, they are usually 1-2 turns out,The problem may not be the carbs
check aircleaner, fuel filters, what did it run like before the new carbs?

You most likely have a float that needs adjusting. For my money, I leave this task to the pros. Get an estimate at three shops nearby so you get a good price. The only other thing you may have going on is some residual crud and lacquer buildup. For that I use Seafoam, a fuel additive that works wonders. IT is available at most auto parts stores. Joe

You will need the centering tool to align the new clutch. The manual says it's part T3880014. It says it is not essential but the job can take some time without it. Triumph recommend the use of an alignment tool (PN T3880014) for use when rebuilding the clutch. The tool is used to align the lifter plate with the hole in the transmission input shaft, thus enabling the pushrod seat to move freely in the shaft when the clutch lever is operated. The tool is not essential, although the installation procedure can take some time without it.
Not horribly definitive, but it sounds like you could replace plates and springs without the tool, according to Haynes.
check out.this will help. thanks.

Get a Haynes Manual. I work on my own bikes with a Factory Manual, The Haynes or Clymer Manual and a Parts Book. If you are going to do your own work you need these books. Period.

Here are some simple diagrams that give the basic idea of what works for the Typanium Rectifier set up.

This is a technically challenging task even if you have the calibrated vacuum gages and the know how to use them. Please see your motorcycle shop and have them balance the carbs on your Bonneville for optimum results.

After these bikes have set for a period of time the oil in the oil tank drains to the lower end of the engine and when started after sitting the oil is usually forced out of the vents for crankcase; which on many of these bikes is through the primary and possibly to the chain oiler etc. Usually after running for a few minutes the oil is back in the oil tank and over supply to the oiler stops! Could possibly soak the clutch plates if it filled primary case also. Be sure and check oil level in tank?! If you added oil before starting it will now be overfilled after starting. This is common problem and will mend it self usually. Does make a mess in the garage toooooooo! Jesse "Leroy" Graves

I found a supplier on internet who had stock of ignition switch, barrell and key.

sounds like oil rings may need replacing,650 are very needy motors, they need regular service and the oil change is the best way to keep them running. also after a spray off at the wash it is a good idea to dry them before a long sit.

Check your connections, recheck them, start from the battery go all the way through in your testing. Personally it soulds like an issue at the coil not getting fire.

A service manual is a valuable tool with an aging bike. I suggest the dealer/mfr. or Clymer books. In the meantime, go to the library reference section...646 stacks should have what you need.
