Pumba the XJ750 project

Great looking build.

What did you rewind the fuel sender with? I've got one that's broke and would like to redo it.

 

I rewound the sender with the original resistance wire, as my target resistance for the new fuel gauge was lower resistance, so I just had to shorten it.

How bad is your old sender? If there is a single break maybe you could get by with just a solder job?

 

I found one from Summit that I can mount onto the bracket that goes in the tank. I'm building an LED guage. I'm just about done and will do a write up on it.

 

Things have been happening slowly but surely. Finally finished the fork rebuild including servicing the anti dive units.

The R1 disc upgrade (new bearings and seals);


Anti-dive valves;


And a few more new bits;


Next update will hopefully be pics of the finished front end complete with the R1 calipers etc.

 

UPDATE PLEASE?

lol sorry I want to know how this brake setup turns out. My bike could really benefit from the R1 brake setup and some stiffer fork springs.

 

Did you get th brake shoes in Oz?

 

From the UK via Ebay

Hope to have some major updates and pics in the next week or 2.

Another order winging its way to me from Chacal...

**** BIG plug for XJ4Ever parts*****

Should have the caliper adapters soonish
New seat cover currently getting made by B&H Specialties.

 

Look forward to the next progress report and pics. Looking good. NigeW

 

A bit of an update, hopefully a lot more will be done in the next 2 days


I am now at the final assembly stage, so now everything gets pulled apart again :laugh:

This is so everything gets checked and tensioned as it goes together.

The spare engine (low Klm Police bike engine) is off to Gav at GD engineering for a strip down - if i find the time to do the engine work myself this project will never finish. If it only needs a freshen up, I will use that engine for initial rego. If it needs a lot of work, I will rego with the unknown engine, and spend time building up a keeper engine.

Some more parts have arrived (XJ4Ever)

Most of these parts are to make sure Pumba is reliable.

New filters and cables;



Cheap blanking plates so I can put a liner kit in the tank easily, fuel tap, breather hose, correct front brake rotor bolts, brushes for both the alternator and starter motor and some other odds and ends .


And the cheap mirrors I have decided on for now ^_^

 

glad to see its all coming together will be just like a new one when you finish. question for you since you changed the controls how did you rig up your choke

 

First fit up of the R1 master cylinder, and there is clearance issues.
Due to the switches hitting the tank, I will play with making some bar risers.


Few more things to update soon.

 

Any new progress? Cant wait to see this done.

 

Finished the headlight mounts and fitted the indicators



Instruments back on as well as the R1 master cylinder and clutch lever set up.


Will tidy up the wiring when I work out the brake lines and throttle cable




Footpegs now tidy and new rear brakes.

 

Old seat cover;


new seat cover;

 

Updates!!!!

Only weeks away from road testing.


Now to sort out brake lines!

 

Looking good! You're mill work is really impressive.

 

All the other Alloy work is mine, but these were made by a user on here!

Took a lot longer than expected, but life can be like that.

 

wow this is very inspirational! There are some extremely talented people on this forum. Great job and please move to maryland so you can give me a hand =)

 

Tank liner kit worked out great


Busted the bank and got braided brake lines


Front brakes now finished.... All lights now working.....

Shortening some of the harness to get a neater look 8)


I smell a road test very soon....

 

Hi darkfibre,
Did you use KBR tank liner ? I just did my tank with it and it came out allright....I can see one small bubble in the top section of the tank but I think it'll be OK. The stuff takes a loooong time to dry: I think my bubble might have been caused by me putting the tank out in direct sunlight.

Schmick work on the brakes, well, the whole bike actually.

Hope to hook up with you and cds1984 for a ride when I get mine out of the lounge room (soon hopefully!)

 

Updates over the weekend

Pics for now, words laterz.

 

Looks great, I particularly like the seat/tank fit, nice work.

 

Front end is now complete. Anti dive units are currently set up as adjustable rebound settings

 

Milestone!

On the road !

Exactly 12 months later; (29/08/2010)


So we can do this

Good work

 

bike looks great

 

Congratulations! Looks like a ripper!
How do the front brakes feel?

 

Brakes are outstanding - no grabbing, and a nice progressive feel. I would recommend the brake upgrade to anyone!

Spent 2 hours this morning at the pits.

Failed on switches hitting tank

Quick bar change and we should be on the road!!! (after a few more hours jumping through hoops at traffic)

 

Nice!
Damn switches! Surely everyone realises you don't need to turn the handlebars 'that' far anyway... sheesh!

BussoBiker is organising a ride for December 11th, Augusta to Busselton and I need at least one other XJ to ride to Busselton with, since I figure we would meet up with him in Busselton to ride to Augusta to ride back to Busselton! Hopefully non_quotidiun will be up and running by then too, since he is from those parts also! What do you reckon?

That oughta test everything out a beaut too!

 

I can agree to something that far in the future!

Reminders may be necessary though

May not be licensed yet, but celebrating putting a few k's on Pumba today!

*Cheers*

 

darkfibre...congrats on all your work, looks good... new shockers next and it will be an even better ride.

 

Any shock recommendations? There only seems 2 kinds

1. Cheap
2. Good

Will be catching up with a suspension expert soon.

 

I'm not an expert but if I was I'd say ... Good. I had stock as it came with, now Ikon and a great improvement they are, tho I have no comparison. $440 to th PO. $$..yes, worth it ...yes.
Or did I jump th gun coz it was already on your list?

 

Neater brake reservoir has turned up;


And we are on the road, and have managed to do a few hundred klms;

 

I'm a super big fan of the dual headlights you got there! Not such a big fan of the digital speedometers but they look great on the bike.

 

The Seca did come with a semi-digital panel
I don't see how that couldn't be taken to another level. For sure, this is something I want to do with my bike. Just look how much more "naked" it looks with smaller lights and gauges... *drool*

It's looking great.

 

Have been trying to sort the front fork settings, and these forks from the XJ750P are different to the ones I can find specs for.
I have now gone to a 20 weight fork oil and 2psi and it seems better.

Have now clocked up 1200klms (about 750 miles) so far this month.



This is a favorite pic

 

Wow, very nice work man. I also invested in the dual headlight setup. How are you liking them?

 

nice work man! good to see another machinist on the board.

 

OK
3,000 klms on (with a 4 week holiday/kids period)

I have been working up to some country runs, for pure enjoyment reasons :lol:


Recently, I was doing the check levels and inspect bike pre ride look-see.

and spotted this;



Now these tyres were unworn, but old as I knew the parts bike that supplied the wheels had sat for ages, I must admit to saying WOW when finding out I had done thousands of Ks with 10 year old tyres.

 

guess you need to buy some new tires

 

This one is already done, rear will be new in a few days as well

 

Wanna buy the rear of my T140 Bonneville - 24 years old and no cracking at all... though it is a little squared-off. It says a lot for Avon tyres.

Nige

 

Tyres are out of the way and Pumba is getting plenty of time on the road, which comes to the next part of the project.

Currently the only warning light for saving the engine is low oil 'level'

The Koso dash has unused inputs for 2 temp sensors with programmable flashing warnings.

I have just ordered a new sump plug so I can fit an oil temp sensor in it, and ordered some new head stud nuts for the head temp sensor to go into.

I also intend to add an oil pressure switch wired parallel to the low level switch.

Pic update later.


On of the reasons for these mods is because of the bloody hot country rides here at the moment. 40++ deg (105++ for non Aussies) I want to know how hot the poor bike is getting.

 

I haven't even been in the garage to work on my bike this week due to our lovely heat wave, can't imagine riding in it.. sticking to the air-con'd Commodore til it cools down a bit!

 

where you get that speedo i need one

 

i have a xj750 seca that i have changed the bars put drag bars on now need to change big square speedo to clean up look

 

Bought the speedo from a seller in the UK called Digitalspeedos on ebay.

Search for RX1N on Ebay, or try here http://www.kosonorthamerica.com/

 

Bought a new sump plug and modified it to receive a temp sensor, and made up a boss to bond to the cylinder head for the second sensor.




Will fit them up on tomorrows oil change and then check accuracy against an infra red temp gun.

The dash can be programed to flash a warning at a preset point. I'll have to research recommended maximum temps for air cooled engines.


The spare engine rebuild is still waiting on me finding oversize pistons


Pumba's old engine will get a serious test this coming weekend doing 1,400klms + (880 miles) in temps around 35deg C (95deg F)
