Ok that makes sense it isnt a completely compatible part. I may get the die grinder out and do a minor mod.

Carried on with the wiring this evening. Got the headlamp wired and checked that there was a spark with the ignition switch on. Seems to be drawing a current all the time though so must have a wire crossed somewhere. Made up the compression release cable too and fitted it. Might be putting in some fluids soon.

hi sly, if you have normal points ignition, the odd current draw, could just be power to the coil (engine in the right position so points are closed) this is why many jap bikes of a similar age have a "run stop run" switch on the handle bars, so you can have lights on, cheque indicators, stop lights etc, without heating up the coil ! if there was a fault it would probably blow a fuse or catch fire ! temporally disconnect the coil wire to see if it makes things better.

It turned out that it was the effect of the battery charger on the zener diode. Once i connected the battery the draw stopped. An annoying day of two steps forward and three back. It turned out that there seemed to be almost no compression and the etremely expensively reconditioned head had to be pulled off to have the valves lapped in as there was considerable leakage on both inlet and exhaust. Sorted with a traditional suction capmstick and fine carborundum. Reassembly starts tomorrow.

No not going to libel anyone, all it required was a quick lick with some fine grinding paste. Just irritating when it is the only bit of the bike that has been farmed out to a shop and it was three times the cost I expected. Once again an opportunity to man up! :).
Good day today though

Yea did that and very gratified to see a good flow back into the tank. I need to sort out a proper way to attach the muffler now and put the petcocks in the tank and I'll be ready to go for a ride. Oh perhaps a front brake connection too. Very keen to see how it rides!

Put the fuel taps in and connect the fuel line to the carb. Sorting out the clutch and brake cables now. Tail light needs a bit of repair but shouldn't be too difficult. One question for the wise heads though. What sort of stap do I need for the battery? I have the buckle with the hook but need to know if its a strechy material or a straight webbing style thing?

Couple of oil drips I need to sort out and my couple of circuits of the block yesterday shook loose several of my bespoke nuts and bolts so I'll need to walk round to see if I can find them. All in all though I'm pretty pleased with the way everything is going. Weather has turned to crap though so I'll have to wait a bit.

Thanks Chaps :) Bit of a leap backwards though as the piston collapsed today. I rode it around the block and was just ajusting the idle when it went clang and stopped. Pulled the head off to find the top ring land had shattered. No other damage and the bore is fine. It was a used piston and the original gudgeon pin was well worn so who knows what it had done prior to today? Ordered a new one which will hopefully arrive in the near future. Glad it didn't go at speed!

No sadly worse news. The liner slipped in the bore and took out the piston.

So I'm in serious shit here. The liner has slipped down the bore and that took out the top of the piston. Don't know if I can get a new liner for the barrel or if I have to find a whole new cylinder. The cylinder head seems ok. It had a piece of piston ring propping open the exhast valve but ive checked out the valve and seat and both are fine. The liner dropped down and hit the flywheels bit it stopped fast enough that no damage was done to the crank. It's a pisser as the piston and barrel were pretty much the only parts that i didn't mess with. Guess it proves that .060" is a bore too far. Bit glum :(

Sorry to hear of your troubles Sly.I was told by my british bike shop to not go past 40 over on a 441.Not enough meat around the cylinder? My 68 441 is at 40 over,so I may need a new liner or cylinder on a future rebuild one day also.

Went to the Engineers today and they scratched their chins and looked a bit gloomy. The problem seems to be that there isn't a lot of meat in the aluminium to spigot the top of the liner. The conclusion was that they would look to see what they could find by way of a suitable stock liner that has a sufficient shoulder on the top to provide an anchor into the barrel and the spigot for the head as well. The initial estimate of around $500 was for a standard straight liner so it was likely to be heading north. Anyway got home and looked again on Ebay and found that whereas yesterday there was but one barrel for sale with .040" already bored out today there was a NOS standard barrel and from someone with a pretty clean record. $600 NZD and I've got a new barrel with nice straight fins and an original hole. Fingers crossed folks I'll let you know when it arrives.

Ok, some what recovered my equanimity today. Had good communication from the Chap sending the barrel so am happy now that a repair is in process. I put the 441Shooting Star tranfers on the side cover and oil tank and gave them another blast of clear. The oil went into the recycle drum with about 2 miles of use but after that prang up it wasnt going to be cycled through the bearings again.
The thing that really has me thinking is how did the sleeve slip? Even taking into account the fact that it had been over bored if it had been cast in it should not have moved and certainly not as much. If you look at the attached pic you can see that it has dropped about 12mm taking into account that the lip of the liner should be above the top of the aluminium. Im wondering if it has aready been re sleeved although after supposedly only ten years on the road to be .060" over on a re sleeve suggests rather hard use!

It must have been resleeved, a factory sleeve cannot drop as they were a wavy pattern on the OD and then the molten aluminium is poured around it, only way to get them out is too bore them out and fit a non factory sleeve. Now it could have been resleeved if the original sleeve cracked at very low mileage not because of too many rebores.

Yes that is possible. I'll heat it up and drop out the sleeve for a look one of these days to remove all doubt but I'm pretty convinced it isn't the original. Still counting my lucky stars that it didn't go as I was fanging around the block. It would have done sooo much more damage if it had locked up the back wheel rather than just stopping at an idle.

Getting on with the instrumentation now. sorely tempted buy a tacho drive that sold on Ebay for a very reasonalble price but seeling a bit over spent now what with the unexpected cost of a NOS barrel and a new piston so resisted the temptation. A speedo though is a compliancing requirement so today I got on with renovating the speedo that came in the box of bits. It has a smashed glass and someone has done a rather ill considered job of un swaging the bezel. I've had a bit of experience pulling these gauges apart. I have access to a nice Formica block that lets me hold the bezel whilst I pry it open without distorting it. The whole shebang can then be put in the lathe on a low speed and re swaged with a roller bearing on a stick. The best bit is you can clean up the movement, the face, glass and tin. lubricate the spindle bearing with watch oil and then re calibrate it on the lathe. I set them for accuracy at 60mph or 100kms as that is generally where speed gets expensive.

A question arises though as the face of this clock is ok but not perfect and it is black rather than grey. I know that the swap over to the black instruments was around 1970 but should my clock have a grey face? If it should be grey I might hunt down a replacement but if it is right I'll stick to this one.

1969 TR 25W Trophy 250 SSM2001/02


1970 TR25W 250 SSM5007/02


just the B25 with a few Triumph covers and a bit off roadish so stick with the face you have, the internals are improved over the Grey too. Be careful with the speedo cable as new ones have too long an inner and cause the internal bush to wear out rapidly.


Added 1969 !!!

Borrowed a lovely old hand held Smiths Machinery Tachometer to check the chuck speeds on the lathe then set the needle to be accurate at 55mph, slightly under reading at 35mph and a smidgen over at 76mph. These magnetic speedos are always a compromise but I'm pretty pleased with how it ended up. All back together again now and ready for the cable and rubber mounting cup to arrive.

From an earlier post. Some pics would be nice as I have access to a lathe and could be the repair as well.

Some info here too but the tool is over complicated.

Argh! I'm begining to believe there is a malign spirit in this machine. All back together with a new piston and barrel. It starts and runs fine but belches smoke. Not sure why but ive run out of interest for the moment and will walk away for a while to gain perspective.

Regathered my equilibrium and pulledfthe head and barrel off again. Couldn't see anything particularly wrong but my mate thought the liner felt a little strange. It had been covered in some form of wax protective which I had washed off with white spirit. I have a bore hone so ran that through a couple of times with paraffin to ensure that the bore was truly clean and reassembled. This time whilst there was still a bit of smoke it wasn't the choking clouds of before. Took it for a couple of highly illegal trips around the block and it does seem to be getting cleaner. Time will tell.
