RG - Extensive clean

[Arronduke]

I had to eradicate cells for this idea, great mate who's a doobie regular had a look this is where he started, and it made sense.
I took it from there.







tighten the thing up.

[Arronduke]

Right I am liking this idea, made the wife look at it heaps. Did not seem impressed. F#ck what else could see be thinking about? Wasn't a beer, she had a wine.

What the Fuck was the response and she let, a man of less character would have given up but not I, I am garageman...!

Haaaa.. yea right.

Back to the job, showing off.!


cant tell me this does not look good...


There is always a big bar when someone is doing a project, and you can see mine... long and hard. 25x25 x1m


Time to measure up...

[Arronduke]

At this point I had no idea how close I had set this up, hence the reason I made it.
Pissed me off that I could not be as perfect as possible, it looked out from this angle or that. I knew it was close but it was pissing me off.

I cant measure chassis etc. This is all I could think off...

So start measuring...

[Arronduke]

To the imbecile... That's 89.25mm and that thing was a caliper and can measure longer than your nob,
6inches... yes a 6inch caliper.

Digital variety if you must know. Not the scale version old blind people use.

WTF
Is that dude flossing is a wheel?

Naa asshole, that there is measuring being done, man style!

Ok just simple telescopic gauges, every shed man has a set, right?

[Ocean1]

So while you have that straightedge there you checked the rear wheel alignment?

How far out were the axle marks? 'Cause I've seen them out a fair bit...

[Arronduke]

Enough dribble.

first thing I did was square the rim. I measured both sides of the rear sprocket to the ali bar, which equalled 89.00mm
I was about 1/8th to 1/4 off a line out on the swing arm lines on the sides of the swingarm.

44.75mm right gap
39.8mm left hand gap

Rear sprocket parallel swingarm.... 89.00mm

Lets look at the front rim.

Sprocket to the inside of the flang, 69.05mm and the flang is 20mm perfect.

ok we all know a squeeze makes a difference but I know how to measure stuff.


a final look before the results.

I have made NO adjustments other than square the rear sprocket to the swingarm, which I would expect is square to the chain.

they were out more than I would have expected.
1/2 to 2/3rds is more realistic on review.

[Arronduke]

Anyway the numbers ...

44.75mm gap right side rim to swingarm
39.80mm gap left side rim to swingarm

44.75 + 39.80 / 2 = 42.27mm
Difference is 4.95mm, the rim is to far to the right by half the difference of 4.95mm = 2.475mm
So..........

44.75mm - 2.475mm = 42.275mm
and
39.80mm + 2.475mm = 42.275mm

or 42.50mm are the equal gaps, now lets make spacers the perfect size.
facts are

Rim needs to go 2.4mm one side so both sides = 42.50mm
REAR SPROCKET ALIGNMENT WAS PERFECT
Yep, the mighty eye, sprocket alignment was spot on but the rim was off side.
Fact is without squaring the rim nothing was possible.

I think it was perfect.

Bring on the chat, its good to be back.

[Pumba]

Arron, cant be arsed looking back in the thread but is the centre of the wheel meant to be in the middle of the swing arm? I know on a some bikes the swing arm is not symmetrical.

Love the strait edge though. Need to make my own.

[Drew]

I would have used the straight edge (which is fucken brilliant by the way), to get the center measurement to the front wheel first. Then figured out what way the rear wheel needs to go to be perfectly inline with that. Then fuck about with the sprocket.

Puma / Drew....... both are correct.

Need to find this out....



This did not end well.
14mm difference between the wheel centres. The front is perfect so the back may need to move to the right 14mm.
Will try this out today........... dam it was all looking sooo good.

[Arronduke]

My new measuring gizmo... starting to get close.
Down to +/- 1mm in axle spacers, amazing the difference this makes to the front rim alignment.

And yes there is a spacer making the gap the same as the rear rail on the rims as the front.
Nothing is perfect but its going to be dammed close.

[Arronduke]

Found this on a bike build site.... pure gold...


Re- wheel alignment

As some of you know i worked on a straightening jig in an accident repair shop for a while & can tell you the accepable misalignment can be up to 4mm on some models as stock we "straightened" quite a few brand new frames for racers to bring them within 1mm of alignment or less & this is what i always aim for on my own bikes

Although this is the ideal, on a bike made up from a number of different parts that were never supposed to fit together the ideal is sometimes not acheivable due to the many variables involved

As posplar says a small misalignment can be tuned out by ajusting the wheel slightly more on one side than the other, the chain will allow you to do this by around 1mm without adverse effects on chain or sprocket life, although it is always better to avoid this if possible

When checking the wheel alignment do not use the ajusters at all ! leave them completely slack & push the wheel all the way forward within the slots & nip it up, the reason for this is that the marks on the ajusters are notoriously poor & the wheel will not be straight if you use them & the front edge of the ajuster slots is usually a fairly accurate place to start your measurements from while with the rear it is not always the case

summary .... 4mm of misalignment is just about acceptable but personally i wouldnt be happy with that
1mm or less is the ideal but not always acheivable
2mm to 2.5mm is the most misalignment you should be aiming for in my opinion & if that is not acheivable you did something wrong somewhere along the line

Hope it helps tone

You gone sober and realized how full of shit you are? Or are you just buried in a shallow grave out back cause the wife caught the credit card statement?

Progress has been slower than any of my bike builds.

[Arronduke]

My poor dear Pumba...me gone sober.!

My hair would fall out and I would start shaking...... naaa .. ok those things have already happened. I blame (thinking) and (more thinking). have to stop my brain hurts.

But to be honest I have been working on my other bikes, BUT this weekend I will be back on to the RG. Organised for the cranks to be rebuilt just need to remove them.
Swingarm will come out to be have a caliper stay welded on as the new GSX600 caliper is not floating like the original.

What I do need is a new delivery address, to many parts are turning up from USA and wife not happy.
Have GSXR1100 front end on it way for the GSX1100EZ. Its going to be great. BUT the RG must be done first and then the 1230 Kat. So why buy bits for a project miles away you might ask? Sorry cant answer that but beer must be at fault.

Oh and best thing I learned this week was to cancel paper statements for credit cards.... brilliant. Wife NEVER sees a credit card statement. problem solved.
