If you've read through the previous posts and still haven't gotten an Ignitech TCI, I certainly can't help you.

Well, the site is back up and the season is 2 races old. Things have changed. Martin is leading the points. Acosta is the new wonder kid. He rode to a well deserved 3rd place after passing Marquez and Bagnaia. Vinales gifted him 3rd when the Aprilia had gear box problems and caused him to crash on the last lap.

ok, back to trying to get this to work.  I believe I have eliminated switch (clutch, side stand.   Does anyone have a known/working TCI ignitor?  Or, I believe I read of an after market option.  The fact that I don't see a single spart when I turn on the ignition seems to be a problem.  Of course, no spart when cranking it either.

thank you

hey, automatic registrations are turned off because there were hundreds a day from robots that I just don't have time to deal with.  cyberhacking has made running a site a full time job.

new users can register however by sending an email as instructed on the new user page.
it's pretty straightforward for someone who is interested I believe.

Sorry, never saw an offer but I would consider them if someone truly had interest.
thanks

TechTalk / Re: Starting problem

The resistance is in the circuit that energizes the solenoid. I've already removed the side stand switch.
I'm thinking that there is so much resistance involved in energizing the starter solenoid that it takes current from the TCI like trying to start with a low battery. It does crank over a little better, but the big improvement is that it starts as soon as it cranks over. The improvement is dramatic.

On one of my Visions I found corrosion in the heavy cable to the starter.  Maybe battery acid oozed/sprayed around at some time?
These bikes are a bit long in the tooth, so there are many things that could be aging / accumulating / happening.  THIS is the meat of the trip/process.  The older it becomes the more Zen.  Not yet the level of archeology, but still requiring some preventive maintenance/coddling/prayers/ and intellectual involvement.

Are you talking high resistance on the large wire coming from the battery to the solenoid? As long as the solenoid is energized the only way to lessen energy to the starter is with poor connections or cables from the battery to the solenoid and then from there to the starter. It sounds like you're saying the solenoid isn't being energized enough to pass electrical flow to the starter.
First place I would look for a problem would be the side stand switch.

TechTalk / Starting problem
Last post by Ron_McCoy - December 19, 2023, 12:04:06 PM
I was having starting problems, starter seemed to be laboring to crank engine over. I replaced the battery, but I was still not happy with how it started. I checked the resistance of the wire to the starter solenoid and it was 95 ohms, way too high. I jumped from the fuse box to the solenoid, bypassing all the safeties in the system, and it starts at the push of the button. I haven't found the source of the resistance yet, but it's never started like this even when it was new. Just push the stater button and it's running. Something to think about if you're having Vision starting problems.

General Board / An Aprilia with Vision specs.
Last post by jefferson - December 18, 2023, 09:23:42 PM
Always liked Supermoto and watched it on tv back when the ama was running the show. Even went out to Colorado and watched one of the races out there. Jeff Ward really impressed as did all the other riders. The Aprilia came out around that time that I saw run in Europe, but was outlawed here and I really like the thing as there was a 450 and 550 version. It was the prettiest of all the bikes running and is still a very good looking and running bike today. My nephew got a KTM 690 Supermoto R and it got me to watching videos and then alot of SXV550 stuff. I looked up the specs and was surprised to see  the bore and stroke is the same between the Vision and the Aprilia. V angle is wider on the Aprilia at 77 degrees. Horsepower is not that much different considering the much newer design with higher compression and EFI and of course weight. My racebike dynod at 57.5 so with frictional losses it should be right there with it. I think the claimed horsepower was 70 and I have seen several figures for the Aprilia and they were all right around there. Yamaha was a bit ahead of the curve with the Vision.

Just looking around and found this thread.  How about replacing the exhaust with a "custom" version like one of the available models?  The big issue is availability of original mufflers etc.  Many have been rusted out and many more have been mashed, dented, and bent.  Nice if you can find one, but there are other worthy systems that you can buy today.  Some spendy but rather nice ones available from Australia (ask POD).  GOOGLE search for XZ550 exhaust system for ideas.
