if you have the heads off, do fit nevada valve springs. I have seen enough dropped V50 valves , not to run any smallblock with the pre 1990 valve springs.
Looks like these springs do not need an inner/outer and should do the trick?https://www.stein-dinse.biz/product_info.php?products_id=460271
Anyone have an idea of where can I can replacement keys for the gas tank? One of them is missing it's key.
Not the same as the ignition switch? Would have been originally. Is there a number stamped on the face of the lock next to the key slot?
I don't have the ignition switch either: it has 1588 stamped on both the tank and switch. Interestingly, the one that I do have keys for seems to have had the switch replaced as it's different from the other bike, and switch does not have any visible numbers.
This will go a little more slowly than I'd like as I'm trying to finish up an Aermacchi Sprint first. I did get the rings out of the stuck piston, and popped a caliper off to evaluate how bad things were. The cylinder bores look great (still have visible hone marks). The only slight concern is some scuffing on one piston.. nothing serious, but worth noting. Based on inspection I bought the obvious replacement bits (for both bikes):Rings27.4mm exhaust valve setsvalve springsCaliper rebuild kitsMaster cylinder rebuild kitsBrake padsCarb rebuild kitsInlet boots (they were perished)Choke cablesI bought enough valve springs for both inlet and exhaust. Can I use the springs above for both sides?This should be enough to get them running and driving. Thankfully, these bikes must have been stored in very dry conditions (probably a dry garage with windows as the paint is faded), and were cared for. I'll obviously have to replace tires and seat covers (one seat base very badly rusted and will need to be replaced). Any recommendations for tires?I'll decide later if they need to be repainted based on how well the paint comes back. They're only original once.
I'm starting to get into these as the winter approaches. I got new keys made and with the parts from Germany I'm in pretty good shape. One exhaust stud broke and another came out entirely as the nuts were seized and the studs were rusted. Does anyone have a recommendation for replacement exhaust studs? I was thinking of using full steel studs with copper or brass nuts.
I also had seized studs and nuts. I was able to get the studs out, but the nuts are stuck to them.Harpers had new studs. Steins had the wrong parts. This was two years ago.I could not find the nuts, nor something similar anywhere. I gave up and used these instead: https://www.mcmaster.com/94150A345/They are not the same thickness and I added spring washers (https://www.mcmaster.com/92161A052/) The washers seem weak and probably useless,but it felt right to add them.I re-torqued the nuts after a few heat cycles. They had not moved. I added a second nut as a lock.I had to buy a pack of 50 nuts. If you want to try them, send me a PM and I'll ship you some.
