ok. Back to subject as ordered. I decided not to drill the boots. process takes too long and this thing has to get running NOW. Or at least this weekend so I can put the car in the shop.
I do wish I would have bought the stock boots though.
Mistermoe I will PM you on the offer.

Any one know where to purchase? Thanks - Mike

Afraid I have bad news to share on the JBM boots. Don James' claim that no air box or other added support is needed may be true with the lightweight mechanical carburetors typical of the ultralight aircraft applications with which he's most experienced, but it is emphatically not true when heavier carburetors such as BS series vacuum carbs or 4-stroke pumpers are hung in them. After two seasons of use I discovered vacuum leaks in the boots. Examination showed that both had split at the spigot stops; exactly where one would expect them to fail due to lack of the OE metal shroud. The boots should hold up well if and only if carbs are supported.

BTW, the OE carb boots were made by ARS, and ARS boots are still sold under the Tour Max label. They are the ones listed as alcohol resistant by 650 Central.

buell88: Anybody have any idea who built the xs650 tracker used in the Draggin Jeans Ad on Pipeburn? May 16, 2017 16:24:09 GMT -5

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. Jun 7, 2017 22:09:52 GMT -5

craig8johnson: Not sure if this is the right spot or not but oh well... Jul 11, 2017 18:04:15 GMT -5

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. Jul 13, 2017 6:54:33 GMT -5

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. Jul 3, 2018 19:15:19 GMT -5

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!! Aug 16, 2018 8:55:08 GMT -5

bob99: how do I post a question. I am new to the forum Jun 6, 2019 10:52:10 GMT -5

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, Apr 10, 2021 2:14:13 GMT -5

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. May 20, 2021 1:19:09 GMT -5

deadlykittin: Hey guys,. i have a 82 xs650 special, super new rider, with almost no knowledge on bikes. So was just riding it, getting used to the clutch and all that. But i was noticed its really hard to get the bike to start, using electric start. And the kick pump--- Aug 4, 2022 17:09:55 GMT -5

deadlykittin: loses compression after the first kick. Ontop of that, i noticed it 1, wont go into neutral when sitting still. and now it dies after getting it started in neutral and going into gear Aug 4, 2022 17:11:01 GMT -5
