Title: Ebay shock: to rebuild or not? Post by: csorin on August 05, 2011, 07:36:20 PM I just picked up a 1998 748 Showa rear shock on eBay for a song. From what I've read in other threads, it seems at the very least I need to pick up a 10.0 spring for my weight (190 fully geared). Does anyone have a reccomendation for a spring, or better yet, a part number?
I've watched a few videos on replacing a shock spring, and it looks straight forward enough. Will I be alright replacing just the spring and putting off a complete rebuild until later down the road? Is there a standard check I can carry out on the shock to make sure it is in working order? Title: Re: Ebay shock: to rebuild or not? Post by: bikepilot on August 09, 2011, 04:40:10 AM I'd at least change the oil in it. Shocks don't hold a ton of oil and it breaks down over time. Any decent moto shop should be able to change oil in the shock - probably ~$100.

My shock is a 749R Showa going on a s2r1k Title: Re: Ebay shock: to rebuild or not? Post by: csorin on August 09, 2011, 12:39:11 PM Ah, thanks guys. If it's going to be 100 to just change the oil, I feel like the better idea might be sending it to GP. They will change the oil, refill the nitrogen, and put new seals on for ~190.
GR, thanks for the part number. Starting to think just sending it in and getting a nice refreshed shock with new spring for 300 is the way to go. Title: Re: Ebay shock: to rebuild or not? Post by: bikepilot on August 13, 2011, 09:49:10 AM That makes sense (FWIW you'll always get a nitrogen refill with an oil change - hard to change that oil when its under pressure [laugh]). Nitrogen is cheap and simple - its basically fancy air - many cage dealers use it to fill tires and stuff now.
