Suzuki / Re: KX 500 Piston in a PE 400
« on: April 26, 2020, 08:16:00 AM »
I've read about using a KX500 (86mm)  In a PE 400, But what about the small end bearing?  PE 20mm Pin 25mm rod.  KX Pin 19mm  . Can't find a bearing 19 x 25 x 22.
  Thanks,
 Steve,

Jawa, Victa????????
Yes. And all modern motocrossers, turbo diesels, supercars etc. And all the other engines where your needle bearing would shit itself in no time. Aeroplanes too. Obviously mamas you know shit about motors. How many have you build that way?

I had a strange one for a parcel coming from NSW to me in Qld. It was sent Mon the 6th from Windsor and on Wed the 8th I got an email from Ebay saying it had been delivered and another from Australia post saying the same but nowhere to be found. Looking into the tracking number through Aus post it had been delivered to the sender and as he wasn't home to sign for it it was taken back to Windsor post office for collection. I finally got in touch with Ebay seller and he claims Aust post stuffed up but I'll wait till I see what is on the address label before I make judgment. In the mean time time I've tried to contact Aust post but impossible to actually talk with a person on the phone so I left an online message but no reply yet. To add insult to it all Aust post sent me email asking to rate the delivery and of course I gave it a 0 out of 10. I guess if it doesn't turn up I should be able to get a refund from Paypal.
Got a parcel coming from Italy and another from China as well but thinking I may not see them for a long time if ever.
You can use your local post office address as your delivery address. Also when you register with AusPost you will get text message or email when your parcel is waiting for collection at the post office. I don't use my residential address for deliveries since Australia post lost 5 parcels and would not even bother offering any compensation. Still see parcels dumped by a post man in car park and in front of storage rooms just because they are numbered. Calling Australia Post is waste of time. Also it is worth asking sender to note on parcel that ID is required when collecting your parcel. Hope that all your other parcels will show up.

Most of "Reynolds" tubing is CrMo, MnMo or stainless hardened steel tubing.  Can be tig/acetylene or mig welded. 4130 simply refers to one of many kinds of CrMo steel that is weldable etc..Only diference between acetylene and Tig welding/brazing is a source of heat. Not many fabricartors/welders can tig/acetylene weld and thats why it is not commonly used but its not archaic . Mig welding was simply developed for ease of use. Can probably train a monkey to mig weld. :)

It will be hard for Australia to recover from this. The biggest industry here is travel and holiday. It will take a while for visitors to come back and the government will make it harder when it comes to turist visa applications(health checks, vaccination etc may be required for visitors). Even if restrictions are lifted people will not just jump on planes and go to see Uluru. They will be happy to find a job. Was a bit ironic watching news today as they had a plane from Wuhan delivering hospital equipment to Australia. China is making money already.Sad

Hi. Brazing is the way to goo. Check this http://www.mojomotorbikes.co.uk/yamaha.html  No heat treatment needed.

Its pretty easy to build a herley frame. You just get some plumbing pipes from bunnings get your grinder,pipe bender and stick welder and of you go
With offroad frames it is a bit harder. CrMo tubing is harder to buy(unless you want to buy a ton) and cost lot more. Than you must be good with Acetilene or Tig torch and CrMo tubing is harder to bend and shape. Then when you got as far as finishing your frame you really want to have it heat treated so it does not crack after a couple of jumps. You don't find a place that heat treats frames on every corner. Custom/replica frame will cost you around 4-5 thousand dollars for a reason.

Notice that Japanese riders had watercooled bikes in 1980 while US riders were still on aircooled in 1981

Would be good to see Australians adopting social distancing and other rules lot quicker than they do and be more considerate to "flatten the curve". Went to shop the other day and apart from seeing empty shells there was a mum with four children roaming around half empty supermarket. Do you really need a whole family to go and get milk and bread? Talked to my friend in Slovakia and she said that you will not be allowed  in supermarket unles you are wearing facemask. Other than that shops are well stocked, you can buy as much as you need. Schools been closed for 3 weeks now. Only around 300 people infected. Big manufacturers such as VW, Peugeot/Citroen, Land Rover/Jaguar, Kia etc have closed their plants for now. Employers pay you 60% of your average pay to stay home. Very little casual employment there. Here we are arguing about when we are going to close schools. A bit sad.

Tech Talk / Re: Bearing grades
« on: February 13, 2020, 04:06:34 PM »
in most of cases discussed here (shaft diameter let say between 10 to 40mm)difference between standard and c3 bearing would be somewhere around 0.01mm. for example standard  bearing xxxx has a clearance 0.005mm than same size bearing xxxc3 has a clearance around 0.015mm. Not a lot but as mentioned earlier it may help when things are pressed together and heat up. It would be quite hard to remove 0.005 from inner and outer bearing race to increase clearance by 0.01 to convert standard bearing to c3,c4 bearing. would have to split cage etc.

would say that 0.01mm extra clearance does not make much of a difference but I guess it may help. When motor heats up everything expands not just inner or outer bearing race. Pulled apart some Jawa and CZ motors and only had standard bearings. Also got some genuine Suzuki crank bearings but no c3 stamped on them just part number. And also got some genuine Koyo bearings. C3 printed on sealed box and after unpacking and checking whats stamped on bearing, there was no c3 just bearing size and made in japan. Suzuki owners manual recommends replacing all bearings with genuine Suzuki ones :P

FYI. No matter where in the world your sending it from, Auspost/Startrack, will be the ones delivering it within Australia  unless you organise your own courier service. Most of the international courier companies ship small items to Auspost for final delivery. If you have tracking which 98% of packages do have, it can be traced  and proof of delivery(signature or photo evidence is available if selected) if it does go missing in Australia compensation can be paid. if compensation isnt offered at a guess the item has been delivered  but gone missing from that delivery point(stolen) or incorrectly addressed or. No proof of lodgement thus not a fault of Auspost.

Express post satchel $12, Trackable and next day delivery or two days if out of major regional areas.
Signature on delivery $2.95

 Remember you will need to be present at the address with adequate safe access for the delivery to be signed for, or it will be taken to a Post office and a card with pick up advice left at your front door or mailbox.


Just get it from MikuniOZ
I can get parts shipped to my dad's address in Slovakia and pick them up when visiting him. No parts left in drive ways and carpark there.
Yes. I have tracking. It says delivered.But nobody can tell me who deliver it an where it was left. I am happy to pick up parcels from post office. I does not bother me. But since startrack started delivering mail I have seen parcels just tossed in a car park and left in front of storage rooms that every unit here has(not a safe place to leave a parcel).Most of delivery drivers can barely read speak or write English. I always leave a note for sender that I signature is required. Not sure who decides where the parcel is left. Its ok when you living in house but block of units is a diferent thing.
When I called post office and asked for compensation I was told that it is only up to 50 dollars for those deliveries. Well that's not even enough to pay for another part and have to pay shipping again. Could have two for that money. I know that Mikuni Oz is a great shop and have lots of parts in stock and ready for delivery but having a shit postal services does not help anybody. Just my experience wit Auspost
