Congrats. Sounds good. You using quick connect lines? Do the flow plenty of fuel?

Thanks!

Yes, I have 5/16" quick disconnects on the tank. Would like 3/8", but they are not as readily available, it seems. I'm concerned that they could be a bottleneck for the system, even though they seem to flow quite well. I had an opportunity to measure the flowrate when I drained the tank, but it didn't cross my mind at the time. Those couple of gallons I had filled the tank with initially did drain back out fairly fast though, through the fitting pair in the RES line.

I seem to remember an acceptable flowrate value in one of the old threads (in terms of X liters in X number of seconds, or something like that), so I probably should research that again and compare to what I measure.

The problem I experienced with my lines not filling up initially was caused, maybe in part, by the fuel valve outlet hose going up hill over the carb to the tee that supplies both carb sets. I'm not sure if there is another way to route this hose, but I'm going to check it out when I have a free minute. Perhaps I can go AROUND the carb without a vertical hump in the hose.

Another thing I need to check is the vent in the tank cap. I had another bike that had some fuel starvation problems due to a swelled gasket in the cap. That bike now runs perfectly after trimming some rubber away in the vent system. I do recall a hissing sound from the cap as air entered the tank when the fuel valve was moved to PRIME. Perhaps it was inhibiting the fuel flow somewhat.

I was just thinking flow if you happen to be running the bike hard for any length of time. I had some quick connects I was going to use but the size was comparable to the lower carb feed lines. I now use a supplemental cock going straight to tank. For safety sake put a tie wrap around the man feed line out of the bottom of the stock petcock.

Mine fell out of the petcock resulting in a wet rear tire that almost caused a high side and resulted in a 30 MPH low side two corners later. The small copper washer degraded and the fitting fell out with the line feeding the carbs still connected. Could of been worse with the high side.

Whoa, that's unfortunate... I need to check my fittings in the fuel valve. Thanks for the heads-up.

Regarding the flow... if there is a hint of fuel starvation, I plan to buy and install one of these TZR250 tank taps with built in shutoff valve and eliminate my added quick disconnects. I will still need to disconnect the fuel hoses if ever removing the tank, but at least the fuel flow will be shut off. A second shutoff for longterm storage isn't a bad idea either.

Hey TwoStrokeNut. My complements if I haven't already said so on your great postings.

In my build thread posting.php?mode=edit&f=7&p=74722


I asked questions about fuel flow because I used similar quick disconnects

Image


This reply came from Wolfgang:
I usually do the following math to get a ballpark figure, using expected max. peak fuel consumption. My calculation is in ltrs/100km as we do in most part of Europe, you can modify this to mpg of course:

Assumed max. consumption is 20l/100km at a speed of 200km/h.
Within 1 hour, you would drive 200km = 20l * 2, so you would burn 40l of fuel.
Your fuel lines need to flow a min. of 40l/hour.

So put a fuel line into an empty bottle and measure the amount of fuel you get within a minute. If it is min. 40/60 = 0,67l, you should be safe. If it is 1l per minute, you can feel even better.



I never did that. The bike has about 2 to 3000 miles on it now. I don't ride it hard (I have others to thrash) occasionally hitting redline but never WFO for any length of time. So unscientifically no fuel flow problems with the quick disconnects.

Keep up the good work :grin:

kpke - Thanks for the kind words. And thanks for saving me the trouble of seeking out that flowrate recommendation! I had forgotten it was discussed in your thread. I will measure the supply flow the next time I drain the tank and report back here. I don't intend to ride the bike hard for extended periods of time either, so I probably will be fine like you. Good to know.

Mike Cichetti - Thanks. It's central Florida for quite a few years now.

Service M13 - Engine Tuning (Part 1 of ?)...

With the cleaned carbs, I’m hoping this service isn’t even needed. But at the very least, I wanted to document how the carbs are currently set up and record any changes, if made.

Picture 327
Image

Yellow highlight will denote where a change was made from previous config. According to what I read, it’s likely the 5L1 needles will eventually be installed. But we shall see after the first ride.

M13 Total Cost: US$0.00 (Needles were accounted for previously)

Service M10 – Kickstart Lever...

The two detent balls are working properly and pivots rotate freely so there wasn’t much to do on the kickstart lever. Although I would have liked to disassemble the lever for a full lube, I decided to simply get some oil in the critical spots to minimize any future wear. The kickstart lever worked flawlessly as is and the joints are reasonably tight. A little needle oiler really works nicely to get lube where you want it, and not where you don’t.

The bike is starting on the first or second kick, so wear on the lever should be minimal. Someday, however, I plan do a full disassembly to get some grease in there.

M10 Total Cost: US$0.00 (oil from stock)

Service E10 - Horn...

The horn was missing when I bought the bike so I found this inexpensive aftermarket replacement on Amazon. It was purchased some years ago, but I believe it was US$10. It has the typical spade connectors so harness leads did not need to change.

The previous owner claimed the circuit worked and that proved to be true. Here it is mounted in its new home. I needed to drill a new hole in the horn to match the two threaded holes on the lower triple clamp, but that was easy enough. Adding some standoffs behind the horn bracket provided enough space to route and secure the front brake lines.

E10 Total Cost: US$10.00 (Horn)

wow a six year build - makes me feel a tiny bit better about my 4 months of nothing more than going from an obese twin to an overweight triple - and realizing I need a petcock solution before going for 4 cylinders.
I really like the twin round headlights - it's right for the bike.

Great thread this, especially for a new owner, clear pictures with detailed instructions...I also like the way your using what works /what you have rather than sourcing genuine Yamaha items.

lost1750GTV – Yeah, it has been an “on again, off again” project for me over the years. It’s “on again” right now and I have hopes to be riding it before Christmas. I’m checking things off at a feverish rate (well, compared to my speed, anyway!).

Thanks. I think the twin headlight set-up is certainly unique compared to other RZ’s. Maybe not my favorite, but its fine.

Good luck with your bike.

podman – Thanks. Unlike most of my other projects, this is a low budget one for me. The bike will never be worth a ton of money due to all the aftermarket parts on it. But it has that RZ engine at its heart and I want to make a good solid rider out of her. Everything must work and work properly. Sometimes going OEM is the cheapest way, like in the case of my worn out shifter. An after-market setup would have set me back much more than a used OEM shifter.
