20 Most Recent 1999 Triumph Daytona 955i Questions & Answers

Water ingress is common. You can sometimes get away with a squirt of WD40 or similar which can loosen any corrosion and get the switch working again. If you have the confidence to then strip the switch gear down and clean the contacts with a bit of wet & dry paper.

Sorry mate but only a Triumph diagnostic reader will reset the EML. Have just seen when you posted this question, cant believe no ones answered it before.

Depends if you have a "wet clutch", if so it may be that the friction plates may be just stuck togeather usually if the bike has been sitting for a while. First try warming up the bike, turn off, put into second gear, then rock the bike back and forth and see if the clutch releases. If not you can try parking on a hill, put in 1st gear,hold clutch in,press starter while sitting in riding position ("jump start"), be carefull

buy a new cap

See other reply.

You CAN use any oil you wish, But I would suggest you use the grade that Triumph specify. In other word a 10W-40 or 10W-30 depending on the temperature that is normal where you are.

make sure you have a good earth at the console ,ie under speedo rev counter ect. restarting the bike as you were doing could temporally reconnect earth ; you need make the earth good by cleaning a reconnect with a little grease or vasaline

you blew a fuse or relay test with a volt meter for open and closed circuit in the relays if they are both open on the ones you check then they are bad if its a fuse look at it and see if the filament is burnt

Usualy on the left side there is a screw on the piece of black hose/wire and it looks like this


Turn it to adjust idle speed.
Hope i helped.

Hello Sir,

I AM TRULY SORRY, that your having to go through this, I cant imagine your pain, as I have a 21 year old son myself that rides a bike, and I always worry about him.

To answer your question is, if the main big steering column bolt came off, then yes, what happen is when he went into a bend, the bike went straight and he could not turn the wheel for the bend. So, it looks like he most likely tried to go around bend, but could not as he turned handle bars, but would not turn wheel. I am truly sorry, and My family will say an extra prayer for his recovery. God Bless, Mike

Hi not to sure about the measurments in quarts, but i do know the 1999 daytona955i holds 4 litres of 15w40 synthetic SH hope this helps, paul

Hi, Do you have the equipment for testing emmisions?
Let me know

The fan will run sometimes after you have shut off the engine. It does this to finish the cool down cycle. Yes the thermostat could be faulty did you experience the overheating before you changed the coolant or is this something that has happened after changing the coolant? With that in mind did you change/replace the coolant with an automotive type or the coolant meant for your motorcycle?
If you have replaced the coolant with automotive type I'd say that was your problem all coolants are not the same automotive types can actually jell in a motorcycle cooling system restricting any coolant flow. IF you have the correct coolant take a look at the fins in the rad, make sure they aren't full of bugs, mud or other road debris. I had a plastic bag get caught up in my rad what a mess getting that out of there. Anyway if all is clear your possibilities are as you say thermostat, rad cap or water pump. If the bike drips a little coolant or looses coolant then you have a water pump problem but normally there will be a wee drip or puddle under the pump after sitting and cooling down another thing and I don't want to alarm you is a leaking head gasket. If the head gasket is leaking you sometimes can see foam bubbles in the coolant when it running and the rad cap is off. Or it can show up in the oil or spark plugs. also if the head is leaking it'll turn the coolant a nasty looking dirty color that can look like melted butterscotch ice cream. There is a few things to look for. hope this was a help

Use 10/40 synthetic or semi-synthetic MOTORCYCLE oil. Don't be tempted to use slightly cheaper car oils as these are designed for use with dry clutches and contain 'friction modifiers' which make the oil slippier to help the car engines run more economically. These will make the clutch slip on powerful bikes which have a 'wet' clutch running in a bath of engine oil. You can get away with car oils in less powerful bikes.

Should be directly under the front part of the gas tank. you may be able to get to it by removeing the five screws on the front plasic cover on the tank or you might have to pull the whole tank.

This sounds like your starter motor is stuck, this is not really my field, but maybe try to remove starter to see what the mesh gear looks like, maybe it is worn to much

Sorry can't find 1999 service manual, but here is the 2002 link wich you can download for free.

That is the dry-break disconnect - it is not uncommon for these to fracture.
They screw into the fuel pump assembly.
You don't necessarily have to remove the pump from the tank, but advisable to remove tank from bike in order to have good access to remove the old fitting(s). You will need to drain the tank to perform the replacement installation.
To remove the tank, you need to remove the seats, tail section, front tank cover, then unplug the two dry-break fuel lines and the elctrical pump connection - there is also another electrical connection on the underside of the tank, for the fuel level sender, so be sure to unplug that one also. Lastly on the opposite (left) side are the two vent & drain hoses which you can pull off the nipples. Two rubber mounts at the front & the one at the back & tank will be ready to come out.

The fittings are not easikly removed - that is because they have a sealant on them that is almost like epoxy; even when whole, they tend to snap off when you attempt to unscrew them. You will mostly need to use an EZ-out in order to get them out. Be patient - this may be quite tedious but important you get all the plastic & old sealer out of the threads before installing the new ones.

You will be best to replace the male and female parts as a set - the o-rings may be leaking anyway on the male fittings at that vintage.

There are all metal replacements available here as alternative to the OEM plastic ones

Be sure to note there are three different sets availabe so match the correct year for your '98.

When re-assembling the tail, ensure that the correct (short) screws are used in the front fitting - those go into captive threads in the tank. If the wrong screws are used they can puncture the fuel cell - not good!!

Good Luck

Sounds to me that your battery my be slight low on charge, try charging it up. Running the bike with a low battery can cause havoc with the stator as well as the pulse coil, those are two things you don't want to be replacing.
Hopefully this helps you out.
