Is the fan working as it should?
Yeah the fans working. About halfway up the temp gauge it comes on
Did u flush out the cooling system before? ... 3LN has 2 block drain bolts at the front
Pull apart the thermostat housing?
How about the water pump ?
Radiator clean ?
Did u use red longlife coolant?
New thermostat and cap would be a good move
What brand of coolant do you use?and do you get it pre mixed or do you get the concentrate and mix it a specific way?
Didn't expect so much of a difference with nulon, way better than the cheap garbage I had in it before. Flushed the old stuff out with water.
Anyone experienced a temp gauge going crazy on their FZR? It's acting nornal until it gets to halfway on the gauge, then it starts going absolutely mental flicking from hot to cold rapidly unless I'm over 9k(ish) rpm.
I can verify the heat is still reasonable as when I pull over and stop running the bike it's acting normal.
Could this be a loose connection that's constantly going on and off because of vibration? Everything else is working normally, electrically.
Anyway I've put 2,000km on Her, bloody love it. it's a really forgiving bike too in most cases(unless you get detoured onto a gravel road that's 26km. Intense!)
The sender to the gauge works on earthing the gauge through the engine/frame. Sounds like a bare wire is touching somewhere and shorting to earth.
Turns out my fzr is not a dirt bike.
I was riding at night and turned into a wide looking corner,
but the inside of the 'wide' road was a section of gravel that I didn't see.
Luckily I was going really slow (probably 20km/h when I hit and 5km/h when I fell over, so nothing really bad happened.
Still though first accident as a rider. Better to crash slow than fast I suppose.
I think I got off pretty easy as far as bike crashes go, it was more embarrassing than scary/painful
Damn that sucks!
Did you panic brake? The worst thing you can do on loose surface is to use the front brake, instant loss of front traction and it will tuck in and drop out from under you. Rear brake to slow down/correct trajectory or look back to where you want to be and power out...
Had a few lowsides, all right hand side, to know a few things.
So what happened was I was slowing down for this left-hand corner, but it looked like a really long arcing, wide corner(couldnt see it with my lights). Thing thing is between this gravel section and road there's a drop of about 6-8 inches.
So when I was leaning in for the corner, and had that sudden drop the bike just went sideways(highside) immediately I ate ****. I'm pretty sure I didn't brake but it happened really suddenly, I may have done.
Well at least no major damage to you or the bike. Did you get the overheating issue sorted?
Yeah I got the overheating sorted, the problem was the coolant I was using. And the temp gauge sensor connector was loose which stopped the fan working but it's all good now
Trying to make my headlights better. found dead links on a few pages that talked about adding a headlight relay to get more current into them or something along those lines? Anyone have any info on this?
I think @my67xr fitted LED bulbs and maybe @Linkin did something similar. I would recommend fitting a Shindengen Mosfet Reg/Rec also. The OEM one is rubbish. You can get a used one from some of the late model Yamahas.
With Shindengen Recs/regs do you have a specific one I can look at to install? Or even what later model bikes have it cause I can maybe get it from a jap bike wrecker I know.
This was mentioned previously and here is where I bought a new one https://roadstercycle.com/ not many big bikes in Thailand so difficult to get used.
Ah, right. Thanks
I think if you follow the LED mod that @my67xr did and the new reg-rec you will have good results.
