Title: Bike rebuild
Post by: Idh on Tuesday, 16 April 2024, 06:08 AM
Evening all.

I have decided my Bertha needs some TLC. Tank is scratched and dented, frame is rusting, so needs a total strip down.
So I thought I would start this post. Thought it may be of interest and I can ask questions as I go.
Looking for some advice as to what to do with the rear shocks.
Asked 2 suspension refurb companies and neither will touch them.
So think I will just blast and powercoat the springs and clean up.

Looking forward to this. Always great to see a 14 being rejuvenated.

As to the shocks, I got some YSS RG342. Quite pleased with them. Based on the recommendation of a former race mechanic for Honda and Suzuki. Ample spareparts for them and a very helpful technical support in their european center in the Netherlands, that answered detailed questions pertaining how to rebuild them. And these shocks were just a bit more € than what I paid to get the oem done at a suspension shop.

Pretty safe to assume that yours need a rebuild or a replacement.

Someone here might chime in with a suspension shop recommendation that still does them.

@Idh Have you tried Maxton's for rebuilding your suspension - they used to do a lot of rebuilds others would not touch a few years ago

Thanks mate, will look at costs!

I think the problem with shock rebuilds is there's a custom sized O-ring they can't get anymore. I'm sure someone once posted on here about that when they were told why the places couldn't fix their shocks.

Thanks mate.

Just taken the springs off and given the shocks a clean. There is no sign of leakage.  None of the adjusters will move, but I haven't moved them in the 13 years I gave had her, so decided to blast and powdercoat the springs, tidy the paint and leave as is. Can always get new ones later.

Just for info, they no longer do them as they can't get the parts.

Yes, that's what they are all saying.

Thanks.
Just got to be careful on the budget. Not trying to make her mint, just loved.
So trying to clean and refurb rather than replace.

Having done a full strip and rebuild on mine a few years ago, here's one little tip for you when you build her back up...
Loom into frame first, then airbox and then motor. If you fit the airbox and motor before you try to get the loom in it doesn't work. I learned the hard way :onya:
I found it easier to lie the motor on it's side on a cushion and lower the frame over it and then get it upright. I just fitted the front end and centre stand so that you could sit it up once the motor was in.
Also remember to reconnect the fuel tank feed pipe union before you try and start it. If you forget as I did it sprays a very large quantity of petrol everywhere, and makes a right old mess :rofl2:

Interesting thank you. I took it out with an engine hoist, but good idea laying it down.

Well, for me it worked when replacing the loom. Needed to take just one connector off.
Title: Re: Bike rebuild
Post by: Hooli on Monday, 22 April 2024, 05:39 PM
I took half the loom out of a 14 years ago after a bike shop had fitted it all wrong so nothing connected properly. The engine didn't come out for that either. Oddly enough after routing it properly the wires were all long enough to reach the connectors they attach too...
Title: Re: Bike rebuild
Post by: Hooli on Monday, 22 April 2024, 05:51 PM
Having said that, I do believe the order specified in the manual is loom, airbox & then engine. So it's probably easier that way.
Title: Re: Bike rebuild
Post by: Andre on Monday, 22 April 2024, 07:53 PM
When the engine and airbox are already out, it is no no-brainer to put the loom in before the former. Just mentioned that it is possible to get the loom in whith engine in place, so some poor soul doesn't take engine out to change the loom  ;)
