Your valued opinion please! Can I still ride with this broken?

[flyingcr250]

Hi Steven,
Yes I am tempted to ride tomorrow. I used to ride a XR500 with one of the hub mounting holes broken, it wasn't an issue but that sprocket was a solid beasty which was more or less seized permanently onto the hub until you fair whacked it off with a mallet.
I wonder if fabricating up a 'C' shaped bracket and drilling holes in it that matched say 3 of the holes in the hub. Placing this over the offending breakage should reinforce it and provide a support for that bolt that goes in the broken hole wouldn't it?
If I rode tomorrow, you reckon I should remove the dodgily mounted bolt? Should it slip off it may damage my swingarm more?

id just leave it out, ive ridden with 2 missing bolts before, i drove home from work with only 4 of the 6 wheel studs on my van, i think you should be ok. just tighten up the remaining bolts inbetween laps. thats what id do anyway lol

I'll listen to you...you're a pro!!! See you there!

Hey Evan, do you remember my rear sprocket bolts breaking at Thunder? Mine damaged swingarm (we had thought new swingarm) & also did same as yours to one of the bolt holes on the hub. John took it into somewhere on Barry's Point Rd I think it was (recommended by Greg at Sprectrum) and they repaired both swing arm & hub plus welded part of the KX's frame for $100.
Unsure what happened first as to what damage was caused when though.

Hey thanks Joan, yeah I'll most probably do something like that to the hub. After googling apparently its quite common for sprocket nuts to come undone on these newer fandangled dirt bikes!!

It came out really good, can't tell its been done and so far has held up good. Think these things do just happened as when i headed out that day mine were all tight but instead they broke. If you want the name of the place send a message through FB to John - he may remember.

Probably brugar engineering. Spelling could be waaaaaaaaaaaaay wrong.

You probably mean Bruin engineering. Tjebbe Bruin (spelling??) I have lost his number now! Look for a Waitamata ride brouchure or thread he has a lot to do with that club ( I think).
He's in Glenfield somewhere I think? he made the fly wheel weight for my Cr250 many moons ago has a workshop in his home with lathes etc he's very good.

Here found it http://www.kiwibiker.co.nz/forums/sh...s-friday-feb-5

nah he means brugar engineering... this guy is down the driveway just past the bendon underwear shop on your way up barrys pt road - #7 . across the road from the foodtown. he seems to like to do everything cheap too

he repairs alloy wheels on cars etc too. ive had him do a few jobs, including repairing a mag on my supra after a sheep broke it (long story)

Just thinking, is your sprocket off center and that is causing the issues?

A sheep story?

Oldskool, I personally wouldn't ride it. You are only going to do more damage. Here is a product that works better than anything else out there in regards to vibration.
www.nordlock.com
These are the biz. Better than anything including Nylock, which are not that great really. I have the Junkers test kit here.
Hylton Parker Fasteners in Albany have them in stock.

once had this problem on my kx, was told to use spring washers and never happened again, maybe a long shot i know!

They look like they'll do the business!

Hub broken, holes flogged out ....bolts/ studs will be moving in holes, nuts will be moving against the hub...This is the Root cause of your ongoing problem....Replace hub, sprocket, studs or bolts and nuts.

You may get away with tightning up as many bolts as you can, then remove one at a time, drill out and fit next size bolts in the new close tolerance holes. Maybe use flat hard washers against the aluminum casting and loctite blue on bolts. Torque bolts up to correct tension for new bolt size.

Awesome suggestion! What you describe gives me a good understanding of what is happening.
This is what I'll do. Seeing as it's flogged already I'll ride it again today (with care and plenty of checking!). Over the week I'll take the wheel down to this Brugar Engineering place as it's just down the road. I'll see what he can do to close up the holes and drill them out and repair the broken one. If a no go then I'll cast around for a wheel. I'll replace the offending sprocket too.
When it's all back together again I'll give these Nordlock washers a go...with loctite, correct torque and sequence.
