Parts falling off bikes & noise

[nudemetalz]

MX mufflers are fairly easy to get off the net.
I bought my 2-stroke one for $100 (didn't work for my 4-stroke ) and my KXF250 4-stroke one I got for $120. This one works really well and as a bonus came with the "quiet outlet" option. The beauty of these too as they're easily repackable.

this is ONE of the reasons i was not out there..
my bike is NOT up to spec YET.

even in the "good" old days, bolts would fall off

but a fuel tank????

sure my fuel CAP fell off, but that is an easy fix... put it on properly... lol

but like Dave said.. MOST were very good... just the usall 1% that slipped through..

but you have to start somewhere!.... this was a very good day for me, made me see what was required first hand.. and the different ideas to get to that point !!!

My $0.02 for what it worth guys MNZ has standards regarding noise testing and it sounds like skunk has access to some suitable equipment.

We were all tested at our last meeting up here at Mt Welly, there were no issues but you cant argue with facts if there are any issues or complaints.

I don't no who else went around the track on Sunday looking at all the marks that were left on the track form the bikes that fell down?I did most were just big long white marks form nylon (great thats what we need crash protection at work) but on the other hand there were big holes and gouges from people not taking the time to protect there bike properly (manly rear axle,foot peg,and exhaust marks) All it will take is one track inspection from the kart club and thats it we are out. I'm not saying you can't crash some times thats out of your hands I'm saying get out to the garage lay your bike down and have a good look at what will,might touch the ground then have a long think about how to make it safe and your nylon staying put just remember the forces that go on when your bike hits the ground and how your tie wire or cable ties are not going to cut the mustard. Do it once and do it right it makes life a lot easer in the long run.

When we walked the track in the morning before racing I did see some marks on the track that were not the usual kart sprocket ones, possibly from bikes at previous days.

Perhaps the morning scrutineering needs to include lying bikes down on each side to check the nylon is actually in the right place.

[Skunk]

I think it's more a case of SECURING the nylon. Too much cable tying without thought to the forces involved. If the nylon moves when you whack it hard with a hammer in any direction it's not good enough.

There's a thought - I'll whack it with a hammer if it doesn't look secure to me. I'm not a good shot so it had better look good.

[fi5hy]

basically looking good is not going to cut it. Think about throwing a 100 kg weight from the back of a truck travailing at 100 kms hr will your nylon hold up?? ask yourself

n regards to F5 Daves comments I am doing my best with my bikes to keep up to speck and am constantly improving them to the recommended standards on Bucket Racing NZ. And do take on what people say and endeavour to have the improvements to the bikes before they go to the next meet I attend. I just had a look and there is nothing about exhausts and noise level in the Resources part.

As to the comments about the exhaust. The whole reason the exhaust came off was another bike basically rear ended her while rolling over the top of the back of the bike. The weld was fixed up the night before and safety wired in two places so if it did work loose it would stay attached to the bike at least till the end of the race.

Please accept things break and fall off where vehicles collide.

Just so you know the muffler has been screwed on to the output pipe of the expansion chamber (so even a hammer wouldn't remove it), will have its own bracket attaching it to the bike and of course a slider on the lower outer edge. I am also working on attaching more sliders.

And finally I did contact Cycleworks about getting an exhaust made, which they priced at $450-$550. Please remember some of use have to make do with what we can make ourselves and unfortunately have to consider a "pre-made exhaust/muffler end" a luxury item.

I do appreciate and love this sport and very much and want to continue.

Would it be possible to have included in the Bucket Racing NZ website suggestions/notes on where Sliders should be placed on a bike more than " Lie the bike on it's side and where touches the ground..." Wanisami is classic example of this, where she was lain on her side and sliders were attached where metal touched the ground. Plus basic rules to what an exhaust must have.

As to people enjoying their barbeques, etc and dealing with noise levels. My view is they choose to live near a track so they should expect to hear engines once and a while. I find the supporters noise levels from Newtown Athletic Park to be obtrusive, however I choose to live where I do and have to accept that there wil be a certain level of noise infringement of my personal paradise and place of Zen.

Sorry but THAT right there is a crap argument. You may accept this but others don't and btw that track we were at on Sunday is within a 'nature reserve' so all you have to have are a couple of moustached hippies crying about the birds being upset and not mating due to the sounds produced and that could be it the boffins in white coats would be down to the track with their equipment so quick our heads would spin. Serious

[Kendog]

Yep. That's the trouble with sound. Deep sounds don't sound loud but carry well. High pitches tend to be annoying without much volume...

So how would my bucket rate with its current deep sound?

Look,...on Sunday I mentioned the fact that your bike was TOTALLY unsilenced while you were on the dummy grid. It was almost deafeningly loud and you come back at me with other bikes being noisy. This was totally unacceptable as I was the Steward of the day and my decision should have been final. The fact that I still let you out was not a wise choice of mine.

I put a lot on the line for the weekend, and if we had any complaints, even one, then the Karters could tell us to piss off.

[Skunk]

I've added bits to the Bucket Racing website. It was intended as a guide (not full-on instructions) and the MNZ rules regarding noise/safety/rider conduct etc are all linked from there as well as the official bucket rules. Some rules we are running to are 'local track' rules.

[Slingshot]

Set the standard, make it known and then enforce it.

And we should stop using the Kart Guys as an excuse to get the bikes up to standard. The standards should be in place because that's the minimum required to be safe.

I rode Frankie for almost 2 seasons, and after most races I'd walk the track picking up nuts and bolts and other random stuff that had fallen off.
If Bayden (or anyone else) had said "thanks for coming, but you ain't riding today because of..." I would have learned my lesson.

We're now bloody lucky to have two tracks in the Wellington area...lets not wreck it by having loud bikes that upset the locals.

And since Sunday, Ella hasn't stopped talking about the "Motorcycle Racing" and how they were "Too Fast Daddy"! If I can't have a boy, I'll at least have a girl that likes bikes
