I think this is a good idea, I'd like one too. I think this needs a sticky.
75 XS650B with 79 forks and dual disc, braided lines, disc brake on back, Pamco ignition, Pamcopete's reg/rec mods, kill switch relay, home made harness, all LED turn, brake and tail lights, tapered head bearings, bronze bushes in swing arm, soon to get shock and fork upgrades
I am placing my initial order for correct-length thermometers tomorrow (Monday). The thermometers are made in the USA. It will take about 2 weeks until I receive the initial release, and I should begin shipping the first units about a week after that.
I tested a few different thermometers, and the original one that I used is the best.
I only have a few hundred miles on mine, but it seems to be quite rugged. Although the gauge is not liquid-filled, the helix bi-metal strip is silicone-dampened, and there is almost no needle vibration.
The finished product will be completely made from new parts. I have solved the problem of the probe rubbing against the transmission gear. The unit will have an articulated (similar to knurled) gripping surface.
I am going to sell the first 25-40 units for about $40-45 plus about $5 shipping. After the beta test, I foresee the price being about $50-55 plus about $5 shipping.
I appreciate all of the interest and encouragement. Rather than replying to this post, I would appreciate it if you would respond to firstname.lastname@example.org and I will put you on a wait list, filling orders in the order that I receive them. In the beginning, I will only be able to make about two or three units a day. Again, the first 25-40 units will be at a reduced price. Thanks a lot. email@example.com

ShakerNorm and pamcopete, thank you very much for your votes of confidence, and thank you for the payment, I really appreciate it.
I'm not really expecting or requesting payment yet, I just want to give this particular forum first shot at my first units, so I am making a wait list.
And, I hate to clog the "30 most recent posts" feature with my enterprise. So, any one else, please just email me at firstname.lastname@example.org with your request, and then I will have your email so that I can contact you when I am ready to ship. I will keep this thread updated with my progress. Thanks again!

dogbunny, Let's put this mod to the test. Team: Slightly Dangerous #s46 races P2 Vintage Sidecar on race courses across the Midwest, East and South. I will be at Mid-Ohio this weekend with other Yamaha powered rigs and see if they also would be interested in your product. Thanks for your time and effort, Dale Lavender
I just received the initial shipment of the correct-length custom thermometers.
Yesterday I recieved the mold-making silicone and supplies.
By Friday, I should receive the high-temperature casting resin.
It will take a day or two to make the master model, then a couple of more days to make and cure the initial mold, and then a couple of more days to cast the first finished ThermoDipStick. It might even take a little longer -- there is not a tremendous amount of work to do, but there is a lot of slow, controlled curing involved, and a lot of slow, back-and-forth corresponding with a master modeler-molder-caster who I am consulting with.
In any case, the end is in sight, and hopefully, I will have the first unit in a week or so if I don't hit any snags. I will post updates.

Here is the first finished XS650 ThemoDipStick. I'll be ready to ship units in just a few more days.
I was even able to reproduce the little recessed area with the tiny raised lip where the gasket goes.
This is the vacuum chamber I built for degassing the mold rubber and the high-temperature casting resin. Degassing is a fancy term that means getting rid of the air bubbles that you get when you mix part A with part B.
The vacuum chamber was interesting. I found a thick, heavy, glass candle holder at Goodwill for $2.99. I also got a thick cast aluminum cook pot at Goodwill for $3.99 -- I only used the lid. The lid gasket was made from a piece of inner tube. All the fittings were $21. The vacuum gauge was $14 on eBay. The only thing left was the vacuum pump. I had a small one from another project, but it only drew -16 h.i.g. mercury. For degassing, you need -29 h.i.g. mercury, which is a tremendous amount of vacuum -- each number is an exponential increase. The harbor freight pump shown cost $80 after using a 20% off coupon. All told, the vacuum chamber cost me about $122 plus some tax.
I just finished casting a second mold and the next finished unit.
In anticipation of getting my new temp dip stick, I've been doing some price checking on the gasket. MikesXS wants $5 for one. The Yamaha retail is only $2.90 !!!!!!!!! Obviously, I won't be buying one from Mike's, lol.
kardon: Wow quiet here, where did they all go.

buell88: Anybody have any idea who built the xs650 tracker used in the Draggin Jeans Ad on Pipeburn?

joshua: The regulator/rectifier unit I got from Mikes PMA has closer hole spacing than original. Are we supposed to mill the holes to fit?
Jun 7, 2017 19:25:58 GMT -5
joshua: My bad. I found the bracket they supplied to mount the rectifier/regulator... Uh oh. How is this meant to work? Which way is it meant to mount? Looks like I have to use some spacers or something. Good instructions would be nice.

craig8johnson: Not sure if this is the right spot or not but oh well...

craig8johnson: I'm checking the charging system. I'm afraid I might have fried the last battery. With the solid state regulator (after market) what should it be charging at. The book says, I think, 15 volts. I'm hitting 17 when revved. Is that too high?
Jul 11, 2017 18:06:19 GMT -5
gggGary: Yes 17 volts is too high, about 14 volts is max, sounds like you don't have the right regulator or it's wired wrong.

tt650: Trying to breathe life into a 1980 that's been stored (indoors) for 25 yrs. Air filters are dry rotted. Have cleaned carbs but she only runs briefly on choke then stops. Need jet setting info and other ideas that might help her idle and rev.

trix13: Hey everyone! New to the forum and am fighting those gremlins!! New charging system, ignition switch, coil and fuse box. Resistance is higher than normal on the ignition pick up so I'm trying to find one. No such luck yet.
Aug 16, 2018 8:50:48 GMT -5
trix13: Also, even though all of my connections are clean, I cannot seem to find out why , when at higher rpms, I hit the signals and the rpms pulse with the signals...hahah. same with the brake light. I appreciate all input!!

jimothyj: Hello everyone, I just joined & wish would have known about this site in 2014 when I brought my 1974 TX650A back from the grave. I have spent a good deal of $$ and alot of time on it. Just painted it and working on electrical, I will post pics soon,

louisvan: trix13 - I had a problem with my 1975 SX650. When I got to highway speeds, the engine lost power. The problem was in the connectors. At a certain vibration and the wind pushing on the wiring loom, the connector lost continuity. A bad crimp to the wire.
