My first problem to resolve this month is that the Fury R1 is not starting easily. It was fine when I took the engine out but, has been problematic since the engine went back in. The fuel pump starts and stops as expected but it takes longer to start than it did before. It definitely feels like a fuel system problem.
I plugged in my R1 instrument cluster and no error codes were showing up. The first thing I'm doing is replacing both the fuel filters and the spark plugs.
I noticed that I'm losing coolant very slowly but there are no obvious leaks.
Fitted the new front left headlight glass. The yellow circle you can see is the LED sidelight bulb.
Whilst I was at it, I tried out the LED H4 headlight bulbs I bought. They simply don't work in my car for some reason but if I apply power to the right pins, they do light up. I need to investigate more but I don't hold out much hope.
My NGK Iridium CR9EIA-9 6289 spark plugs arrived. A set of four was about £40 delivered.
Whilst these have made a difference and the car runs smoother and with more torque, they didn't help with the slow starting issue.
My new TJ QFF0062 fuel filter also arrived today.
The pre-pump filter also arrived. I'm using this to catch any crud that might come out of the fuel tank before it gets to the fuel pump. This filter is 56mm in diameter.
Because my tyres are nearing their end of life, my speedo is a fair way out compared to the GPS speed from my satnav. I re-configured the Digidash2, to see if I can improve this.
The weather has turned cloudy and colder but I found some time to change both fuel filters. Changing the pre-pump filter was easy. I have a removable cover/diffuser on the rear of the car and access to this is good.
One thing I did notice and I have no idea why this would be the case, is that this pre-filter half fills with air as the fuel is pulled through it. It always has done this though as far as I can tell but, it just doesn't seem right to me. There is no obvious way for air to get in when the tank is more than half full. I'm going to see if removing the fuel filler cap makes a difference. I'll also replace the hose from the tank to this fuel filter in case it has a tiny split that is letting air get sucked in.
Changing the main fuel filter was a lot harder and much more time consuming, as I expected. I got there in the end though and also replaced some of the fuel hose as it was just easier. It still hasn't cured the slow start issue though :-(
I also took some time (whilst I had the diffuser off and better access) to add some clips and foam to the handbrake cable, to try and stop it banging on other metal parts.
I made the classic mistake of introducing two variables :-( Having installed the new filters, I then filled the tank with a Jerry can containing older fuel. I went out to see if the new filters and plugs had improved things and the car was running roughly.
So, I drained the tank. This was interesting as it showed the rate at which fuel goes through the pre-pump filter is really slow. So I've now removed this pre-pump filter completely and now have a a straight through 8mm hose from the tank outlet to the fuel pump.
Filled the car up with fresh fuel and went for a test drive. The car started immediately and was running much better. Holy crap! Out on the road, it's like I've gained another 20-30hp!
Went out for my first proper drive of the year in the evening sunshine. The car is going really well in the cool air and rarely saw temperatures in three figures, despite pushing on. Looks like the cooling system has settled down nicely.
In an effort to try and locate where some of the noises are coming from, I have swapped my super light-weight titanium exhaust for the standard Yamaha R1 silencer. It's a lot quieter and I can actually drive the car for a short time without ear plugs.
I have also removed the passenger seat and harnesses, to remove them as a possible source of noise and to clean underneath the seat and check things over on that side of the car.
Having removed all these bits and put a quieter exhaust on, my car is actually running quite well now. One thing I did notice is that with the centre tunnel top rear section removed, a lot of warm air comes out into the cockpit.
There is a bit of backlash in the diff but this is normal apparently:
It's a really messy job to do but I replaced the diff oil today. This seems to have made the diff a bit quieter. Popped out this afternoon for a test run and it's going well :-)
Finally got some good weather and a car that is running really well, so I popped up to Orford via some of my favourite local roads. They were practically empty too :-)
No one at the castle either :-)
Some great driving over the last few weeks. The Fury is going really well.
I have noticed that I'm still loosing a small amount of coolant, each time I go out in the car though. I can see that a seal on one of thermostat inlet pipes is leaking slightly, so I've purchased some 19 × 2.5mm o-rings and some Lithium soap-based grease.
The manual shows what is going on nicely. New o-rings should fix it and 'LS' stands fro Lithium Soap-based grease.
The parts have turned up, so I had a look at the thermostat housing. There are two pipes that are bolted to the top of the head and it looks like there is some corrosion where they enter. My guess is the rubber O-rings have given up.
If I'm going to do one, I might as well do them both.
This was a good call, as they both looked like this. The o-rings were mis-shappen and crumbling.
The pipework has been cleaned up and I've painted above the O-ring too. There is a 3rd O-ring on the pipe connected to the thermostat housing and was also be replaced. Cleaning up the engine side is harder as you need to block the hole, to stop all the dirt falling in. It's all now back together and torqued up.
I've bought a new hazards light switch, to work with my new indicator circuit. It's a latching push switch (16mm) with both NC and NO contacts. It features a light up ring (red).
This will replace a large, complex and expensive hazard light switch and the new one weighs just 8.5g.
The camera makes it look orange but it is a deep red light.
