Does anyone know the measurements of the 2J4 and 48T model swingarm spindles? I've seen a few on German Ebay from the later model SRs and would expect them to be the same length and diameter as the 2J2, but I want to be sure before I part with my hard-earned!!
Cheers.
John.

I have seen as late as 1988 spindles fit into 1978 with no issue, I think the only difference is the new ones have grease nipple threads both sides, regards, carl.

Here goes, while i have zero idea what 2j2 and 2j4 and 48T have to do in identifying what bike the spindle (axle/pivot) came out of - here is my findings: The approx. year xs650 (pivot) is too long, but the same diameter, the XS400 (which I have in my possession right now cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&ih=019&sspagename=STRK%3AMEWN%3AIT&viewitem=&item=290178656580&rd=1 is 6mm too short (kinda), and the stock replacement-new from Thumperstuff-is $57.00 Mark at Thumperstuff measured the xs650 pivot for me, and it is close to an 1" longer than the SR. The '79 XS400 swing arm pivot bolt that I bought off of e-bay fits perfect in the frame hole, it slides right into the bushing, the bearings are a perfect fit, it has zerk fittings on each end to lube the bushing and probably the bearing is a little too short. When I put the pivot bolt into the frame I get about 4 to 5mm on the other side of the frame to thread the nut on. The thinkness of the nut is ~10mm, to the threaded portion of the pivot is 6mm inside the nut. I could probably use a shorter jam nut and have it flush. I am really confused on which way to go, spend $57 and us Thumperstuff's new replacement, or use the xs400 with the lubricating features and have it a bit too short. What would you do. |

Just my 20 cents worth, pay the $57 and get a new one the right length.
Cheers

The parts fit straight in...my brother has just done the same to his as well, just to re-inforce the opinion. ...and I'm with you RD...why not make life easy... SR  |

I had a standard Yamaha swingarm bolt snap on me at Eastern Creek in March. It was right on the drilling for grease and I've heard a few people had the same happen. Steer clear of drilled swingarm bolts is my advice.
I'm getting a bolt made for me out of solid bar. Will be fine for racing if assembled with plenty of grease, for road use, if you ride in the wet a lot, you need the grease nipple on the swingarm to pump grease in.

Well, I am still deciding what I am going to use. I have already reburshed one end of the old swingarm bolt with a grinder. I still need to get my frame back from the powder coating shop before I decide.

The GS1000 bolt in the center will fit but it's longer so the other parts are probably longer too.
