- I'm still not certain if I'm understanding this correctly. I've also read that these don't actually do anything, and the bike will run the same whether or not this thing is plugged in. Somebody tell me what I'm doing wrong.

I've just done my 2001 sv, I had a first reading of 5.43 k.ohms, which meant I needed 4.1 k.ohms at WOT, I too ran out of adjustment at 4.2, I didnt modify my sensor slots and snugged the fixing screw down at 4.2, the sensor wasn't a million miles off before I adjusted it, informative video, many thanks.
Thanks Michael. Hopefully you see some improvement. I'm still not convinced it does anything though, hah. I'm going to disconnect it on the track at some point this year for a session and see if I can notice anything different.
Just did mine as well. Got 4.05 on the open and it was almost pinned to one side of the gaps too. Going to put them back in today and see. Also did the rebuild and clean on them. The ethanol build up was bad on the brass. And the slides were sticky. Cleaned up all functioned good on the bench. So we'll see.
Good deal--yea, it'll never hurt to get the carburetor nice and clean. At the very least, it removes a variable when troubleshooting a motorcycle.
The jury is still out on whether or not the throttle position sensor on the carbureted SV650/GSF600's actually does anything. If you go onto the Bandit forums, it sure seems like all the experts there state it doesn't do a damn thing. However, I just can't accept that, lol. Why would it be on there at all if that's the case?
@@matttriestodothings I wish I had an answer. Makes a huge difference on my Old Chevy vortec when it comes to shifting. But these carbs are so simple I don't see it doing shit. Going to sync them here shortly. Already purring with the clean carbs and new parts. I did the full deal too: new plugs, oil, coolant flush. Checked the spark plug weep holes etc. Did go up a tooth on front sprocket for less rev at hwy speeds. Should roll out the garage tomorrow after sitting 2.5 yrs.
@@elementalmetal1745 thats awesome man. Hearing a bike fire up after a long hiatus and a bunch of work done... Man, it always gives me a smile. The grin gets even bigger once you actually get on and accelerate!
Make sure you double check all the safety items before you roll if you've been working on it. Caliper bolts are and axle nuts are two that I've, *gulp*, forgotten until I got to the end of the street because I'd been doing work on and off for so long.
@@matttriestodothings Good call. Yup been through everything on. Slow and safe is how I work. Once I get frustrated or burnt I walk away for a few days. Then get back to OCD on it.
On old jaguar cars I have known people file the TPS slots a little to get the correct readings.
Hey, thanks a ton, I did a rebuild on these carbs and I'm sure this is my hiccup.
Make sure you're starting with a clean air filter as well. I'm not convinced the TPS actually does anything, but it can't hurt to have it right.
@@matttriestodothings interesting. When I did the rebuild this summer I think I messed with an air screw and remember messing with the TPS. At the time I didn't know what it was. After putting it back together (new air filter) it ran pike crap, misfiring intermittently (fire correctly, then crapy) to the point where I couldn't keep it running the last time when doing a vacuum test.
I've got the exact same problem on my bandit. It needs to be 3.8/9 but it won't get there unless I leave the screw out, best I can get is about 4.16. Apparently they're set incorrectly from the factory and I assume this is the reason why. I'm going to see if I can try to jam something in the gap so I get the right reading.
As for what it's supposed to do; I've read on forums that it only affects fuel economy and possibly throttle response due to the feedback it gives the ignition control module but most people leave it unplugged as it isn't noticeable in terms of performance. That being said however I had a different set of carbs on before and they wouldn't let the bike run right at all if the TPS was out of whack, this set I don't know about because I haven't had the bike running well enough to notice yet lol.
Please tell me your username is a call to The Brak Show.
Because now i want to watch the Brak Show.
To your point tho... I took a frigid ride today on my bandit for about 25mins before my hands froze. It's running as well as it ever has. I think when it warms up I'll just straight unplug the TPS and find out if it's actually doing something. Interesting you mention incorrect from the factory. This seems like it should be cut and dry but it certainly isn't!
@@matttriestodothings It is 😂
Found this. It might help.
Have you tried switching the sensor with the one installed in the.SV650?
Maybe the one installed in the bandit is bad somehow...
Going to be getting 8" of snow again this afternoon/tonight. It'll be a while until I can actually test it out. I made a big swing on the positioning on the Bandit, so once this bulljive winter finishes up I'll hopefully be able to get on the bike and test it.
@@matttriestodothings I feel ya I’m in Michigan too. I just recently got a bandit and have been working on it for a couple months trying to get it right. Low and behold the tps is bad
Lol. I don’t know how many times I’ve been on a forum reading something and going oh no that’s not right. Maybe I’m being tricked to give the right answers.
Hoping somebody watching videos with a trigger finger for correcting people comes in, calls me an idiot, and tells me what to do. It'd be one of those rare situations where everyone leaves a winner.
Do you know where to buy a tps for the gsf 600
It'd be cheaper to buy a crashed bike and pull the TPS off of one than to buy a new OEM one. Prety sure it's part number 13580-03F00. ~$195 new. Maybe there's a cheap one floating around on ebay.
It's also debatable by the people that really know these bikes well whether or not it even impacts performance. Don't take my word on that though--I haven't done the necessary testing to give an informed opinion.

What exactly does this effect on a carbed engine?
I believe the CDI will advance the timing based on the engine RPM and throttle position sensor reading. That being said, I don't actually know how intelligent the CDI boxes are on these carbureted bikes. Hopefully winter ends early and I'll actually be able to butt dyno the bikes and figure out if I actually made any difference in the responsiveness.
Ah, okay. That's what I thought too. I'll end up doing what you have once I rebuild the carbs later this coming month.
Tengo una sv 650 y enciende con dificultad y cuando enciende acelerando poquito tira mucha candela por escape
Google translate: "I have a sv 650 and it starts with difficulty and when it starts accelerating slightly it draws a lot of candle through the exhaust"
The SV650 choke plungers are known to get scored and stop functioning correctly. My initial thought was that you've got a vacuum leak somewhere but "candle through the exhaust" suggest unburnt fuel. If you've already cleaned the carburetor, I would bet on choke plungers being the problem.
where did you get that book from i need one
Pretty sure it's the sv650 clymer manual. Likely picked it up on ebay.
I want to ask what kind of book it is?
I believe I was using a PDF download of the factory service manual. Same information is in the Clymer manual for an SV650.
