Race Plastics - plastic welding

[random rider]

The number boards on my partners 2004 RMZ250 have pulled away via the bolt.
Now trying to put them back on the hole is too big.

We have tried to Fibre glass them to make the holes smaller but it breaks up and the boards come loose.

Issue
He has custom graphics on them and we don't want to have to replace those again.

Does anyone know of anyone that can plastic weld on the back of the holes so we can make new and smaller one's?

PM Hayd3n hes a professional plastic welder, he might have some kind of trick or some kind of plastic in a tube shit.
Hes always talking about some crap that dries hard to plastic and can be welded to.

what about a longer bolt and a big washer so you secure it from the face of the number board, not down the hole? that might look a bit ugly though

or you could see if you could get a rubber bung or some rubber washers that you could pack into the hole about half way up and then bolt through that?

that will work if its ABS but nothing else as all the other plastics on bikes are chemical resistant and they only real way is to plastic weld them

The first option would be last one...but sorts issue out!

I like the second option though...could be a good quick fix. I have PM for the plastic weld but need to find out the type of plastics they are....sorry thought all plastic was similar

Robs Plastic Welding in Te Awamutu. Awesome plastic welder. Hes probably done the same job a few times before. He gets work sent to him from all over NZ. It will probably cost less than new graphics too. Much less lol.

Bit horey but....

I've had reasonable success with a soldering iron.... melting the plastic on either side of the crack and melting it together, can also trim some plastic from the sticky out pieces they normally have inside the number boards and melt that in too to give yourself more plastic to work with.....

Depending on the bikes plastics (I know it works with the newer RMZ's) you can combine the above with a cable tie, drill a hole through the above mentioned sticky outy bits inside the guard and another around the close by lip of the inner rear mudguard and cable tie the two together.... means you need to replace every time you remove the number boards but how often is that? Bolt hole still works for seat removal and due to the cable tie theres less stress on it letting your budget repair last longer.....

Worked for me anyhow

Cable ties work a treat if its in a place where you can get round the back of it
