GSXR-750 camchain in a CB500/550?

(1/3) > >>

Oddjob:
Been reading about one riders experience using a 1990-95 Suzuki GSXR-750 camchain instead of the usual DID chain in the 500/550 engine. Evidently it's flat sided so kinder to the tensioners, has a larger contact area so is quieter than standard. It's longer so means you need to split the chain and re-rivet which is a set back but can be done with a push bike chain splitter, he reused the existing rivets.

Evidently he's fitted one in a race engine revving to 10000rpm and he's done over 20 races with it fitted without any problems, most of them at insane RPM.

Anyone ever heard of this or tried it?

Since found the same chain in 90 links, unfortunately there appears to be no 88 link available, 90 links is only just over £22, soft link another £1.20. From all accounts the chain is stronger than the standard chain being a 219FTH chain.

Nurse Julie:
I thought the GSXR cam chains were Hyvos? I'm sure that's what the workshop fitted last time I had a GSXR. Maybe mine was a different year / model though 🤔. The DID 219 FTH are what we stock, fit and sell. I'd love to know where you saw them for £22.
90 links sounds very short to me for a DOHC system.

Oddjob:
No 90 links were what I spotted when I was looking to see if they did an 88 link version so I didn't have to break it. The GSXR-750 uses 118 links and it's not a hyvo, just a flat sided chain.

Got a ton of DID 219FTH chains not far from you in Lincoln, https://www.bandcexpress.co.uk/shop/transmission/chains/timing-chains.htm?page=2, turns out they have no 90 links so I got sent a 94 link instead for the same price. Wemoto also sell the the DID 219FTH at £33 for the 118L version or a Tourmax version inc soft link at £41. https://www.wemoto.com/bikes/suzuki/gsxr_750_ws/95

There's quite a few 88link DID ones on flea bay between £25-£30 on my searches ref, part number.  14401323003

I don't stock 88 link Roo as we rarely use them these days but I stock 94 link DID 219FTH and I hold stock of soft links as well.
