Where to get oversize pistons for GS1000??

[shadow]

I'm hoping someone here can help me.
I've disassembled the top end of my gs1000, hoping to just give it a hone and a new set of rings.
There has been water in cylinders 3 and 4 sometime in the past, and they are beyond a light hone.
I've been searching for some 0.5mm oversize pistons and rings with no luck. They are "unavailable" from Suzuki, as are the 1.0mm oversize.
Wiseco only seem to offer the big bore kits, but I don't really want to have the jugs bored that big.
Can anyone recommend a source for some quality oversize pistons?
Thanks.

Several listed on ebay, standard, 0.5 over, & 1.0 over. I have no clue any info. but maybe a place to start.

Thanks for the response.
The only ones I'm seeing are the Wiseco 73mm and 73.5mm.
There are some used factory looking ones, but they don't specify a size, so I'm assuming they are standard 70mm.

I don't understand. when I look at ebay, Suzuki GS1000 pistons, they are there some .5 over (70.5mm), some 1mm over (71mm) & raw powersports show Weisco from 0.50 oversizet to 3.50 (73.5mm) oversized. Or maybe I'm reading it wrong. Good luck.

Cruznimage, maybe?

No idea what year GS1000 you have or whether it matters, but anyway...


Cruznimage has a pretty decent reputation around here. I've installed some of their carb boots and everything seemed high quality and fit perfectly.

I've used the Cruzinimage pistons with good results. I've also used the Wiseco's in race engines.
Cruzinimage as a search term on ebay should bring up pistons - it certainly used to.
They are to all intents replicas of OE and available in the oversizes you want.

Sorry, but I'm still not seeing anything 0.5 over (70.5mm).
Could you possibly supply a link?
Thanks again.

I have seen the Cruzinimage kits, but I was leary of the quality.
I would prefer something from a more reputable company (Japanese/American), but I will have another look.

It's a 1978.
I'll have another look at Cruzinimage.
Like I said, I was concerned about quality, but the price is right!

Cruzinimage is one of the ebay sellers & Raw power is another, that have them. Sorry, I don't know how to do links & stuff like that, I know very little about computers.

Cruznimage is a Japanese company. The parts I installed were shipped directly from Japan, complete with groovy Japanese newspaper packing. Whether the parts were actually made in Japan, I dunno.

If you know the actual dimensions of the rings you want Total Seal makes rings for almost everything.
... and the fact that they are some of the best piston rings made is bonus.

Cruzinimage don't do eBay any more

Here is a link that dates back to 2013 that has a lot of information about the quality and experiences. Not Suzuki but Yamaha, i wouldn't think the parts for different makes would make a difference to quality

Just looked again at ebay, Cruzinimage still lists them on ebay 0.5 over & 1.0 over & they ship from over seas (China or Japan). Rad Powersports show 0.5mm oversize to 73.5mm 10.25:1 compre. I don't know & never ordered from either, just read their adds.

73.5mm is 3.5mm oversize for GS1000. That would be a Wiseco big bore kit. If you want .5mm over get the Cruzinimage from eBay.
