HELLO guys I have been enjoying this site for quite awhile Iguess its time to get involved MY story goes back to 1971 when i was a mech at a honda dealer in Orillia Ont A customer called and said his cb 750 would not go over 100 mph . WE told him to bring it in .HE arrived in the pouring rain .I set up the valves carbs and ignition because it was still raining Itold him that I was not going to try a speed run I woud just take it around the block When I got on to ride out the door the back end felt strange Ichecked and found the spokes in the rear wheel were so loose you could move the rim side to side I had not looked at this part of the bike as he had told me he had just adjusted the chain before he had ridden 40 miles in so we could adress his hi speed issue I adjusted his spokes trued up the rim and sent him on his way next time in he claimed it was now doing the ton as easily as it had before and it did not wobble around at that speed like it had been.
They've recently built a new bypass around town, 3 miles of brand new dual carriageway, no cameras (yet), nowhere for plod to hide, 3 miles of long sweeping left into a very long sweeping right, lets see what the Mercedes will do (3.2 litre supercharged)
There's supposed to be a gentlemans agreement among the manufacturers of European motors of 155MPH to keep the tree huggers sweet although if you know the right people at the dealership "things can be done with the ECU" , I think the previous owner must have known these people well .
Lets just say an indicated 168 would have earned me at least 18 months of kicking the soap outside the showers before I'd dare bend over to pick it up, she was still accelerating but I ran out of road, rock solid, no feeling at all that the car couldn't cope with the speed.
I need to take her home to Stuttgart just once before we part company (I bought her as a "need to have a mental car before I'm too old" sort of thing) a run on the Autobahn where on the right day in the right place there are no speed limits! I doubt I could ever afford the petrol though, the instantaneous fuel consumption at the time read 11MPG .
I would never ever attempt that kind of speed on a bike, I'm not insane just needed that once in a lifetime "aw F**k it" event , I can just waft along now confident in the fact that any spotty little oik in his Impreza/Evo/Skyline will be dispatched effortlessly should I desire, I've done it once so I don't need to do it again.
Well some of those little oiks know what they are doing and can make them Impreza/Evo/Skyline's really haul. With the twin turbo engines 350-400 hp ain't hard to do. Top speeds of close to 180 + isn't unheard of.
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
Well, you guys got me thinking about the 1st real bike I ever rode. About '71 or '72, in Homestead, FL, my brother had a Norton stored in my Dad's barn. My brother was working out West, my Mom & Dad were away and my wife and 3 girls were with her folks in TN. I hot wired the Norton, rode it in the pasture til I figured out how to shift it and put it on the hard road. (Up til then I had only ridden a Cushman). Two more pieces to the story, in So. Fla where we lived in the country, all the roads were on 1 mile square grids and the speedo cable was broken. The tach worked and I rode all over with that Norton showing 4500 RPM in 4th gear. At about 3500 the front end started getting "light". My brother told me later that in 4th gear you could double the tach reading and that was the speed in MPH. In other words, 4500 RPM = 90 MPH. I had a ball for a couple of weeks till my wife came home and I had to stop.
I got over a 100 on a new 81 650. Once, when I was young and stupid at the same time, I took my GS1100 EZ Suzuki 300 RPM past redline. Redline would be 138 MPH. I satisfy my urges now with 0-80 fun, mostly in my Fiero GT with a 3800 GP engine I put in it.
Yea I rode a "modified" Suzuki GSX, the original owner had it up to 180 mph, the second owner had it up to 150 and while going uphill I had it up to 130 and the carbs started to starve, the fuel just wouldn't run in fast enough, when it started to buck because of lack of fuel I backed off and decided that that was all I needed, it was like riding a rocket ship from 50mph to 100 though. I've had my XS up to about 80, don't think I wanna go any faster on it. A funny / not so funny story though, I had sold a Honda 450 to a friend, (yes he's still a friend) who decided to take it on the highway out of town at full throttle, on a long sweeping curve the rear wheel bearing seized up and caused the aluminum hub to heat up and expand letting the wheel do a nasty wobble, he needed all lanes to get it shut down, he sold it right after that incident. While speed does not always kill it sure changes the odds.
The very 1st bike I ever owned was a 1980 KZ440 with chain drive and the only brand new car or bike I've ever owned . I lived in Webster Florida which state highway 471 runs through going directly north to south, absolutely straight as an arrow for well over 20 miles once you cross over state highway 50 heading south. I took my KZ440, with an 85 mph speedometer, out one night to top end it riding alongside a friend on a late model Triumph Bonneville . According to the Bonny's speedo I hit 102 -103, but I had to hug the tank to do it. The bike felt rock steady at that speed . In 1981 this area was desolate, but with lots of wildlife, especially alligators, crawling all over the place . Needless to say, alcohol was the fuel that inspired the driver and I wouldn't do it again . I've had all of my XS650s up to at least 90 mph and just guessing ... my best bet is they'd top out at 105 to 110 mph in stock form . The KZ440 had a 6 speed and I'm guessing the 6th gear was quite a bit more of an overdrive than the XS650's stock 5th gear .

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.

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.
