Shocking advice

[evo550]

I am doing a pre '78 resto and need to find a pair of shocks, without having the originals to measure from I will be guessing the length of standard shocks, so my next option was to find how shock travel is measured by MA for the pre '78 class, this will at least give me a starting point.
Anyone a scrutineer?.........or have a set of phantom gp2 betors lying around that they could measure eye to eye.

Recommendations for aftermarket shocks ?

Yes YSS shocks you talk straight to the man   and they help you with all your needs and there right here on Aussie soil  jimson

What brand and model motorbike is it ? We have most specs for pre 78 .  Ones your specs are established ,you can then choose the type of shock(s) you need, depending on your needs and budget.

ossa phantom gp2 '76

According to my specs , they need to be 340 CTC.  Does anyone have a different spec ? Ossas are not an everday item in Australia . Its all the different brands and models that ad the spice to VMX.

YSS, I have a pair of original RM250B remote resevoir type shocks. Are these units rebuildable, if so what methods used to open them up and repair/rebuild, my understanding is that they are a sealed, non-servicable unit. Are they gently cut open then rewelded??

[YSS]

They have to be cut  and then caped , but you will loose about 6 mm in total lenght. So unless you want to restore it to original condition , new shocks are a better , quicker and usually a cheaper option . ( a new set of E302 for the RM B is only $450.00 a pair )

hey walter how did you go with my rm370 shocks i hope big al has sent them
rusty......

[YSS]

As far as I know , big AL has it under control. Perhaps give him a call.

YSS, I think I buggered up my last message I sent so i'll ty again.
What are the telltail signs that these shocks have been opened up and rebuilt? I've tried adjusting the dampening on these units but are unable to hear the clicks that you listen for in the adjustment process. They seem to have a weld bead about 25-30mm down from the seal area. Would this be where they were opened up and would opening them up loose the dampening adjustment capability??

[YSS]

Can you send a pic ? then I can tell you for sure

YSS, They're back on the bike, I'll have to remove them and pull the springs off. I might do it later in the week, it's too late now, I'm off to get some sleep.
