I wonder if powdercoating spokes post assembly might require one to re-true the wheels?

The trick is that the spokes will be a different color than the hub and rim.

Probably your stakes are not drilled out deep enough.
Defiantly right, not drilled out at all!
Thx

Finally.
Managed to put together enough money for my parts list. Placed order and should be in the mail in about a month, due to some parts not in stock at present.
Progress none the less.
I've taken photos along the way, but not sure if I've taken enough.
Any suggestions of a rebuild tutorial, in the forum. That will assist with a 71 500 engine build????

Finally got my package with all the goodies, now the engine build can begin. Excited and daunted at the same time.
Any tips or tricks that might prevent any noobie errors would be appreciated.

So these are a couple of videos I've shot to try and determine the lift and duration.
Roughly or perhaps even very roughly.
Part1:165deg-170deg duration with.304-.307 lift
Part2:160deg-170deg duration with.307-.312 lift
Duration sounds wrong, the specs quoted were 320 duration(mild street grind) .312 lift. The way I came up with my duration number was to count the number of deg. From start of lift to the end of lift

There is plenty said on this forum in regards to that age old question "airbox vs pods" and from what I've read airbox wins in most instances (my opinion). With the exception being when performance mods are made, ie, ports, cam, exhaust and after market carbys (cr's) as stock carbs designed for airbox airflow. With the mods I intend to have being the Mild Street cam and tuned headers, perhaps the electronic ignition is considered a performance inhancement or not.  I am wondering if I should go down the pod path. If I had the airbox with the bike when I bought the bike I would just use it. All it came with was the merge chamber, so even considered running a single filter on the back of that, which I've seen done before.
I'm very much a novice at all this and I'm not looking to re open again the airbox vs pods debate( there is plenty already said). The reasons I ask the question are one I'm a tight arse and if I have to source an airbox it will most likely be from OS and funds are ALWAYS tight. Two, can I make do with what I've got? (Chamber. + filter). Three, Do these mods justify considering pods? I've also put into consideration my ability to tune the mongrel once it breathes. I ask because I have zero experience with these bikes and I know many here have had experience with all the variations.
Not looking for long scientific responses(any information appropriated). Just as many as possible.

Thx for the offer Tews19, looks around $50 - $80, depending on size weight and express features. What I'll do over the next day or so is post a picture of what I've got. I think at least, I need the filter box.
I found a complete set over here awhile back, but the owner was difficult to get organised and it fell through.
It's a 500(71) in a 550(77) frame. Not that it makes a whole lot of difference. The 550 box has a breather pipe on the bottom and I don't think the 500 did.

This what I've got
Not sure what's got 500 origins or 550. Apreciate the tuning tips.  Footy fantasy went over my head though.

So my engine assembly was come to a standstill with the discovery that I've lost some parts. I'm trying to determine their correct description, so I can find out their part number and order replacements.

When I look up the schematics for gear shift fork on CMS the parts are on the picture but not on the shopping list. 1&30 are the spring and bearing ball for the shift drum screw, they are the parts i've lost. As well as the 57mm, 52mm set rings for the transmission.

Does anyone know who stocks the spring and bearing ball?

Also the neutral light switch cam has broken it's locator lug(almost all off). I can feel when its in the right position, but should probably replace it while I'm there. I'm not sure where to find its part number either??

Any help or advice is always appreciated.

Thx calj.
Yes #9 looks like the switch I'm after. Also temp. Unavailable, I'll get the numbers down and search to see if any available. I'll have a search on the forum and see what I can get from a parter.

Does anyone know what, if any model 500 had the spring and ball bearing on the transmission fork barrel retainer screw. I'm struggling to determine which model they were on. Mine being a 72 500.

Back into this build.
I'm just about to start a complete assembly of the motor, this will be my first engine build of any kind. I've taken photos along the (disassembly) way, but probably not nearly enough.
I have the service manual, which I followed for the disassembly and plan to use it for the reassembly. What I have noticed is it lacks tip for reassembly i.e. where to apply lube on assembly or sealants where there isn't any gasket or even not to lube or seal????


Any tip on available aids or posts that I can use to help me along the way?

Or any tips from your own experience?

Thank you calj737.
I’ve got a tub of redline assembly lube which I plan to use.
Just need to make sure I put it every where it needs to go.

Just a couple of questions in regards to the 72 500 shift drum screw assembly.
I got a new bearing ball and spring, but not sure if they are the correct size or even required on the 72 model, as some models don’t have them. The balls diameter is larger than the inside diameter of the collet guide and the spring outside diameter is considerably smaller than the inside of the collet guide.
Does this sound right?

So I’ve started to put the cases together and stuffed up.  I knew if I didn’t align the bearing dowl pins properly,when you tighten the cases together they get pushed through the casting.  I thought they were, but one obviously wasn’t. Next picture shows the result.  >:(  :-[


So now I have to strip it all back down and do a welding repair.

Thx calj737,
I’ve got some 4047, but only in 3.2mm. Might get some 2.5mm for such a little weld.

I,m about to install new head studs.
Any tips or hazards I need to be aware of?
Do I avoid anti seize?
How tight should they be?
Thanks in advance, advice has been much appreciated so far and will continue to be.

Thanks calj737.
Excuse my ignorance, what does 12# mean? Is it a torque setting? I understand ft/lb but not familiar with this one.

I’ve moved away from the fibreglass seat cowling to a aluminium one. Much happier with the new shape.

So! Let’s get this build back on track.
I’m looking at assembling the rims. Any one had experience with painted spokes? Whether pre painting prior to assembling becomes an issue, when tensioning does paint crack?
