footgoose Posted May 27, 2021 Posted May 27, 2021 sounding like fuel maybe. one of those disintegrating filters? water in the tank? can't remember is the bike new to you? 2
jetboy Posted May 27, 2021 Author Posted May 27, 2021 its not SUPER new. 3 years? there were a lot of dragon flies. still- that should not have those symptoms. I'll clean it out anyway as soon as the guy gets back and I can borrow some more tools. Meanwhile, I think I may have found it. the timing sensor cable must have been too close to the engine, the rubber has two burn marks in it, making divots. I don't see any wires but it could have been enough to fry them. I may take it out and see if I can repair it. any harm in just pulling that sensor side with the hex bolts? or do I have to do a thing before I do that? may totally not be the problem, but it looks suspicious. hopefully someone in town is better at soldering than me (also I have no tools for that one) 2
jetboy Posted May 27, 2021 Author Posted May 27, 2021 seems not so uncommon: looked on ebay and see the same damage (but mine is much deeper) on that one for sale. https://i.ebayimg.com/images/g/QbQAAOSwR8hdyz03/s-l1600.jpg
Scud Posted May 27, 2021 Posted May 27, 2021 You can remove the sensor if you think the wires are damaged. Just be careful on re-install that you have the correct spacers. There could be none, or 3 spacers, or who knows... whatever. Just put it back exactly how it was. They are very sensitive and need an exact gap to run properly. FYI, I do have a spare ECU and possibly other stuff, that I could post tomorrow if you have a need (and I agree that needing and ECU seems very unlikely.) 1
jetboy Posted May 27, 2021 Author Posted May 27, 2021 thanks! well, I at leasts straightened it out.. got it away from any heat. I also checked those connectors under the fuse box- my box has two hex screws holding it it. one WAS a little loose- see if that helps. once I fix everything then it should work! gonna give it a try in a second. got to get the tank back on and such and getting tired. and its getting cold.. fog is rolling in.
Scud Posted May 27, 2021 Posted May 27, 2021 When you find the problem, you can say "I have found it" - which is a fun thing to say in Eureka. If you don't believe me, just ask Archimedes. 1
jetboy Posted May 27, 2021 Author Posted May 27, 2021 well. I took it out- tried to get to town and it started off fine.. then crapped out completely. I had to push it back and it was like 1/2 a mile and I am now officially exhausted. I am starting to think: YES it could be bad gas. at this point its all I have left except that one wire. and the wires seems to have no effect if I move it or pinch it etc... so its probably fine actually. unfortunately. If its bad gas that will be excellent- as I can just get new gas. I got petrol at a fairly normal station up here-- but it DID start to happen right after i got that gas, and progressively got worse. perhaps as I ran through the decent gas still in the tank. seems crazy it could really be that bad, but its worth a shot. Drain, Seafoam, and fill. maybe that will fix it! tomorrow. its dark now. 1

Josh, I suspect that your phase/revolution sensor PN GU01721600 is bad. It is a coil of very fine wire inside a resin body. It can work ok when cold, but become open circuit as the engine warms up. If the connection in the coil wire is intermittent, then the engine will be erratic.

R.I.P. Mikko Posted May 27, 2021 Posted May 27, 2021 Did anyone suggest the side stand switch? Bypass that.. If you do suspect bad fuel, try using Heet instead of seafoam. Maybe a can of octane booster if that’s available there. 1
Chuck Posted May 27, 2021 Posted May 27, 2021 My bet is on the phase sensor, too. It certainly can't hurt to put fresh gas in it, though, although didn't you have this problem before the trip? 3
fotoguzzi Posted May 27, 2021 Posted May 27, 2021 I agree with Chuck. That sensor wire makes a sharp angle when mounted sometimes and can break or stress the wiring inside, can get worse when engine is hot as the wire shielding can get soft. 2
