Allan's restoration issues

[TexasDave]

G'day,

When I first got my FJ1100 I had to clean the carbs three times before I got them right, this bike is VERY particular about carb cleanliness.  If you do not know where the emulsion tube is, do some research in the carb files as they are very helpful.  Only on the third attempt did I clean the emulsion tube.
If the overflow pipes leak petrol after a good clean, the carb seats and needle will need replacing, the ones that attach loosely to the float.
And safety wire your petcock...

cheers, Gareth

I have a friend with a large motorcycle collection. His biggest decision before going riding is which bike to choose. He does not own a FJ but does have a FJR and a VMax among many others. All his bikes look brand new and he is meticulous with maintenance. His VMax is 2nd Gen with carbs. Since the VMax is also VERY particular about carb cleanliness and it might not get ridden regularly he drains his carbs after every ride. He has routed tubes from the carbs to the side of the bike to collect the gas when he drains the carbs. With the methanol and pollution additives in what they sell for gas here in Texas this might seem like alot of trouble but alot less than pulling and cleaning them.  Dave

Decision made, carbs off and found float 1 hard on and would only go down if I pushed it down, bowl 1 & 2 all gummed up. I think a good clean is in order before they go back. I will let you know how it all goes.
Cheers Allan

   Allan, might be a good time to replace the needle seat "o"rings while you're in there. Be sure to clean the choke circuit jets in the float bowl housings. These will cause you lots of grief if they're not clean.
                                                               Regards, Pete.

Alan, while you're in there...do yourself a favor and get the ss screw kit from RPM.
Replace all those soft JIS Phillips screws with much more durable SS Allen's.

You *will* be glad you did...

Cheers

This is pretty much what I found when I dismantled the Project '92 carbs to investigate the fuel leaking everywhere. 2 of the floats were "stiff", and 3 slides were "gummed" to the point they wouldn't move. Have thoroughly cleaned the bodies now, but I am not reusing any small parts, new kits going in on this job. Slides/diaphrams are all in good condition.

Good luck!

Hi George,  yep all ordered and waiting for delivery.  Everything has been given a good clean.... it really needed it. Will let you know once I have everything back together.

Well its been awhile and all the parts arrived,  the carbies had a good clean with all new parts inside and all screws replaced with stainless allen heads. no spare parts left over which is aways a good thing and after some jiggling and sweating they finally went t back into place.  With some more fuel she kicked into life, no more fuel over the driveway. ... yippe. Did some repair work on the fairing, replaced all the instrument lights as well as a new headlight globe, speed bleeders on the front calipers (magic little things they are) we were ready for our maiden voyage.  She runs a little low at idle almost stalls at take off but other than that it was pure magic.... we finally got there..... cant wait till I can bring her out again. Thanks everyone for their advice and support. Special thanks to RPM even with the cost of shipping to Australia it was way cheaper than buying through a bike shop here, saved me a bundle.  I will put some photos up shortly With a list of things I had to do to get her running.
Cheers Al

 great news!
you could change your pilot jets to a size larger, that could help that low-end stumble

Just going back to bleeding the brakes again.

I recently fitted a different underslung calliper to the rear of my Spondon race bike.

These underslung can be a pain to bleed as the master cylinder is above the calliper.

I tried a Mityvac, normal bleeding, topping callipers up with a syringe (both bleed nipples), raising the calliper above the master cylinder.

All to nought.

I Pulled the m/c apart, and cleaned it all up. No joy. swapped the master cylinder for a known good one. Zilch.

The I found my old pressurised bleed system that I bought years ago. It has a cap that fits the master cylinder reservoir and is connected to an air source, like a spare wheel via a fluid reservoir.(not too much pressure though - around 20 psi)

You just connect it all up (you can put fluid in the reservoir - its designed for cars really -  but I just top the the master cylinder reservoir level up & keep an eye on it ). Open the bleed nipples and watch all the bubbles appear. I bled it all out cracking both nipples twice (ouch !) to the lower level on the reservoir and bingo I got brakes again.

I think it was an Oxford product.........??
