loosen the drain screws on cylinders 3&4 to see if you get any fuel out?

When you cleaned the carbs, did you blow through all the galleries with compressed air to get all the crap out? Did you replace the fuel filter?

Chances are, as i have had it before, dislodged crap has blocked the carbs completely from getting fuel or the jets are blocked again. If it starts firing on all 4 at higher (above 5k) revs then my money is on blocked jets. If it still wont run on all 4 then its blocked flue galleries.

All of the above assumes that the coils are correctly connected to the correct cylinders. #1&4 on the left coil, #2&3 on the right coil.

@BBROWN1664: No reactions from the dash lights@TOM VR46: Interesting post, thx. So checked the operation of the sidestand switch and got continuity with sidestand up, so all good. Clutch switch also fully functional.

Starting to suspect the issue is related to the Starter Circuit Cut-off Relay as this is connected with the fuel pump that suddeny got silent (no more ticking sound when turning the key). See if I can manage to check it and order a used one on Ebay. Will post the outcome when part has arrived.

No reaction from the dash lights suggests the start switch circuits do not think the start switch is being pushed. The dash lights will come on if the bike is in gear with the side stand down etc and when everything is working normally (you just dont see them as you relase teh button quickly)

you need ot investigate the wiring diagrams relating to the starter switch.

Maybe check the main fuses again.

put the bike on the main stand, put the side stand up and pullthe clutch lever in. Make sure the bike is in neutral and then press the starter button. Do all the dash lights (oil etc) come on when you press the start button now?

thank for the response
have tried all that,soaked in carb cleaner over nite.must be really badly blocked
can you see daylight through yours when clean
think i might have to renew mine.been in there 20 years
regards

Remember that one of the three in each carb is actually a blank and is blocked.

The yamaha manuals are in the download section to give you the official yamaha figures

you could drain the carbs off first but the jets may be blocked anyway.
Give it a squirt of easy start to see if it runs on that - this will prove its fuel related rather than ignition related.

If i remember correctly, there are normally 4 pipes from new on these bikes.

- Fuel tank overflow
- Fuel tank breather
- Carb overflow
- Battery overflow

You need to trace them back to see which ones you are looking at

I did about 120 miles after picking it up and had previously been riding a 23 year old Tiger 900i and a 23 year old FZS600. Compared to them the ONLY thing i could find wrong was the seat. It gets uncomfortable for me after an hour so a Bagster seat has been ordered already. I have not played with or checked the suspension settings yet but it seemed fine to me. Maybe one of the previous owners has done something with this already. It has the standard screen on it which didn't cause me any issues either. The engine and brakes are superb. This really is the modern FZS to me. It is light and nimble but is quick and handles well. Just like the original FZS600.

I did try sitting on the Tracer 700 and found it too small for me.

Camchain and tensioner will not have failed at that mileage. Probably just needs a good service and a thrash to get the tensioner to move out a notch

Varifocals would be the way to go, with reactor light lenses if not too expensive. Worth taking a crash helmet with you to the opticians so that you choose a frame that’s compatible with being shoved over your ears repeatedly. Some stylish but flimsy frames won’t last five minutes, or are not rigid enough to be pushed past your ears at all.

Or wear a flip front one to save taking the glasses off

I ride with varifocals with no real issues. You dont need to move your head so much to read the speedo etc.
