You topped out at 145 in 6th? There's something wrong cause I hit 151 and I was nearing the limiter and still slowly going. This was a while so I could be completely wrong.

Just about yea, almost bouncing it, probably had 1 more shift light left before It was there..

Regardless, Im having to go into 5th mid-corner.. cause I cant throttle out of the corners, Im out of MPH in 4th at 115..

Not going to preach to you about doing 115-130mph around corners/sweepers on the street. But true the 1 & 2nd gen Daytona does not have the same top end power of an I4 600cc especially the narrow focus band of a unrestricted R6.
On the streets is where your bike will typically excel over those top end breathers, as your NOT doing 135mph, which is close to where a 675 tops out in 5th gear (real speed)..

Be safe man, in whatever you do.

eeehh...it's kind a public road..

It's a road that runs right near the local airport and is rarely used. 3 lanes wide either direction..minimal traffic except airport staff..

And I abuse the shit out of it...

 

[Toothless675]

Yaaaaaaaaaaay!! And the shit storm continues!

I rode the bike to work last night and home today...and its been fairly warm here now, up into the high 80's.. and comin home as I got more into the traffic I saw I was only 2 bars from the top of the coolant temp gauge..

Well, as I pull into my spot I see that I am just dribbling coolant out from the bottom of the bike..It got to about 1 to 2 bars from the maximum...but no Idiot light on the gauge cluster, the fan was running.. bike has engine ice in it.

Regardless, it let out quite a nice amount of coolant and I can hear it bubbling and boiling in the expansion tank..

So...Without having time to look at it cause I gotta get to bed, I work nights..start at 10, 1hr commute there, I get up at 8..

My Possibilities are..

1) Bad Radiator cap - Cheapest option..homing so.
2) Bad Cooling Hose somewhere (I have a suspicion as to which one)
3) Blown head gasket
4) **** if I know..

Regardless, when I get time Im gonna get a coolant pressure tester and strip the fairings off and pressurize the system to see if I can spot the issue.. But..

Gonna probably dump the oil and pull the plugs...see if they show signs of a bad headgasket.

Sooooooooooooo much for Racing this Sunday...

Daytona Strikes again...I think I just need to stop taking it to work..last time I rode it to work I lost an engine on the way home..

 

[posnikb]

What about something as simple as just overfilling the coolant? That plus a long ride in hot conditions can cause it to overflow and leak everywhere, then making it too low and causing your issue of boiling.

I dunno, trying to be hopeful.

 

[Toothless675]

Curious....the little steel vent tube that goes through the oil pan...is that a weep hole for the water pump?

I dont think the water was coming out of the over flow vent tube...but directly under the middle of the bike which I fear is a a weep hole..

 

[Toothless675]

JD? MacBandit?

 

[jdgun_13]

OK to start,... how many miles, what tune, mods, and what has changed in the last say 200 miles (mods?)

under the bike, which side specifically?
taking it you did a radiator flush and went to the engine ice?
very possible you have air trapped in the upper radiator hose (top of radiator to thermostat)
showing 2 from the top happens depending on conditions, and also what tune are you running (if any)?
your fans coming on is a good thing....
any loss of power?
have you checked your hose clamps for tightness to make sure you are not sucking air into the system somewhere?

 

[MacBandit]

Yes that's the weep tube for both the oil pump and water pump.

No additional modifications since I've had it up and running, which has been around 1k miles.

I did flush the Radiator and the block actually, and yes. Im on engine ice.

You would think that if I had an air bubble in the system I would've had issues much sooner.

I ordered a new Cap, Thermostat and seal from the Dealer yesterday. Been reading around the forums and TriumphRat, appears to be a common issue.. My only real concern is that I did not observe the coolant coming out of the overflow vent tube..

And as Mac just advised...\/ \/ \/ It's coming out of the Weep hole for the Water / Oil pump.

There is a chance one of my hoses is compromised, the lower one that goes near the sprocket.. I might also get a hold of TJ for a Samco Hose kit..Assuming that it isn't my pump that is shot..

Figured Cap and thermostat are easiest to change and the cheaper. $10 for the cap, like $50 for the thermostat... spent like $67 at the dealer.. and he had to order it all...so I'm going to miss my race on Sunday..

Yes that's the weep tube for both the oil pump and water pump.

That's Kinda what I figured..
From what I understand, the Oil and Water pump are one unit..is that correct?

It would appear as though Changing said Water pump with the engine in the bike is a pain in the ass.. is it possible?

I know there is the chain that goes around it.. assuming that the water pump is driven by the Cam chain? it's been a while since I've been in there.

I have the old one off of my other motor that shit the bed on me..I can try and clean it out incase of any debris and swap them..

Or do you think it could be something OTHER than the pump itself? From what I've read the Pump's dont actually fail on these bikes..not often at least.

Going to dump all the coolant out of the bike as best I can, flush with Water/Vinegar Solution and refill with Distilled water and Water wetter with a new cap and thermostat then do my best to bleed it out.

Where is the bleeder screw located? when I bled it last time I just burped the hoses that I could gain access to with the cap off and the engine running until it stopped drinking coolant.

My water pump failed on my '11 Tona 3 months after I got it. Lets hope you fix the problem with the parts you ordered.

What ya thinkin Mac? think its my pump?

What other reason would cause it to dump DIRECTLY under the bike and not out through the blow down tube on the over flow?

You'd think if its the pump it would over heat instantly though..

 

[MacBandit]

Okay I'm confused. You noticed it leaking out of the weep tube and you asked about how to change the water pump so I was just providing a link with instructions on how to replace it. I'm not inferring anything else. It's not a pump failure it's a seal failure but you still have to replace the whole unit. But since you're there you might as well upgrade it.

Just went back and read some more posts. I hadn't read your posts about overheating. I had only read your post asking what the metal tune coming out of the middle of the pan is. It's unlikely your water pump is causing the bike to overheat but if it's leaking from there it still needs replaced. As for the expansion tank boiling yes a bad radiator cap is the most common issue.

It has been doing fine for a while, it was only the other day on the really hot ride home that I noticed it once I got into stop and go traffic getting really hot, at which point I noticed it dumping out of the weep hole because I didnt see it coming out of the over flow tube.

So I'm trying to pick your brain as to if I should try a cap and thermostat first, or do you think, because of the fact alone that it was coming from the weep hole means that its a failed water pump.

Just saw your edit/update.
And I read through your post several times on the water pump oil pump. I recall trying to offer parts when you were first discussing changing to the newer style.

I'll have to reread it to review the benefits and costs again. didnt you have a bunch of troubles sourcing the cross over pipe?

 

[MacBandit]

I also went back and saw your posts about top speed. Your not at the re limited yet. Ignore your shift lights. My Street Triple with a 13k rev limit and the same stock gearing tops at 142 in 5th. Your Daytona should be close to 150. It depends on what the actual re limiter is set at by Daytona. I say actual because triumph sets it at 12,500 on the Strert Triplr but p spec is 13,000. So let's say the Daytona hits the rev limiter at 13,500. That puts top speed in 5th at 149 and in 6th at 162.

I added more to that post you last read. Sorry I frequently post then go back and edit right away.

If it's leaking out the weep hole then you'll have to replace the pump there is not option. That doesn't mean it's the cause of your overheating however. As I mentioned in my edit the most common cause for boiling into the overflow is a bad radiator cap.

The newer pump is fairly easy to find on ebay if you know what to look for. Yes the feed pipe is nearly impossible to find there but you can get it from Triumph but it takes 2 weeks since they don't stock it here.

 

[Toothless675]

Siphoned some coolant out of the over flow and back into the engine Ice bottle.

Pulled the side fairings off, appears as though my cap got loose and may have started sucking air.

Checked the oil pan where the weep hole is, it's dry. So Amen I don't think it's a bad pump.

Fired it up after refilling the coolant.. Ran it with the system sealed. Ran until the fan came on. Didn't overheat or push coolant. So, gonna let it cool down then open the system and see if I can bleed air out of the system

 

[Infamous_D675]

Literally spend like ten minutes with the cap off burping the hoses. You won't believe the amount of air. Then lean the bike as much as you can side to side. You may have to refill the coolant/water. Once you do that. Start it up and give it a few revs and burp it some more and rock it side to side. Then cap it and let it warm up. My bike idled for 20mins and never went past 6 bars. Fans would kick in and back down to 5. Added coolant to my overflow on the min line cold and no problems. Of course I replaced my cap just to be safe too.

 

[Toothless675]

Everything appears to be fine now, Still on the Original parts. I have a new Cap and T-Stat sitting for me at the dealer.

This thing has so much more work to be done before Ill be happy with it......so many things to buy.. damn money pit. Could've had a Matte black 2015 675R if I hadn't messed with this one so much hah.
