GS750E Rebuild Update

so do you have a wiseco piston kit installed on your bike or a overbored suzuki one?

do you have the boxes the orginal rings came in that you broke? there should be a suzuki part number on it. if so please post, should be able to find some

-ryan
 
I have the OEM suzuki oversized pistons .5

I tried to call ahead and explain to to my brother but he didn't understand what I was asking or what I was looking for. I'm driving over there tonight to find the packaging the rings came in to verify the numbers they gave me I know I didn't toss them since I had incorrect parts given to me before and that is a big headache enough as is.

Will follow-up later tonight

Reached shop and to the guy that got me my stuff... he looked into it and seems I got my rings because I ordered pistons with them as well; but somehow they don't think I should be able to just order 'just rings' that sounds really absent of another word 'retarded'

he is going to talk to some guys and get me taken care of so I'll keep an ear to the ground and wait until he gets back to me either tonight or tomorrow morning.
 
ron ayer sez that number is discontinued (12140-31311-050)
but 12140-31311, which are piston rings as well and is available. maybe the 050 is the .5 overbore? may still want to try ron ayer or bike bandit and see if they can pull some strings.

been there already no luck... guy at the shop is trying to work something out I'll hear from him soon
 
funny... well I went ahead and ordered the pistons with rings... I don't know who at suzuki came up with that idea but they are laughing all the way to the bank. Ofcourse they are backordered so I will have to wait who knows how long before they get them in... I'll keep an eye out for just rings if I can find them but at least I have a set coming to me so I'm back in buisness again.
 
wiseco rings only fit their applications unfortunately I would need ot rebore my head to 3mm to fit their kit...

Je pistons I looksed at their catelog and have made attempts to get help from their tech department but I didn't get a call back... more than likely I won't be able to do much unfortunately with them ....

I could be wrong but I'll give it another shot tomorrow; might work out but with my luck on how it has been the last several weeks I am highly doubtful
 
Success!! I got my pistons in from the shop so I am back in action with new rings!

Now I'm going to put them in with ring compressors this time around and do this right.. and if all goes well I will be ready to test fire my newly rebuilt motor by weekends end.

I cannot WAIT!!!:-D
 
didn't work out for this weekend with working on the bike.. I was interested to know if anyone has used the craftsman piston ring compressor... looks like it would make things very easy since the wholepiston fits inside it and can be poped out after I slide the block over the pistons...

anyones take on these worth it... I don't want to break another ring so I am asking for your two cents guys and girls :-D

..cost of two would be about $18

I've got an old set...1970's version Craftsman and they work great. Put the rings on (off set the gaps), slide the whole assembly into the compressor and drop it down from the topside...hook up the rod cap snug not torqued, and remove the compressor. It's just that easy! :-D
 
from the top of the block down...can't go from the bottom to top? ... just ask since I already have my pistons on from when I first attempted to put them back in...and I probably can't get the snap rings out again without needing to get more... doubt those hand ones will do any good or be easier *sigh* looks like I am going to have to take off the pistons from the rods and go in from the top... crap.. think I'll have to pickup more snap rings

You don't need to remove your pistons from your rods. Just slip the ring compressors over the top of the pistons and over the rings and just snug the compressors so they slip off with the cylinder sleeves.

Sorry..........I left that part out. You need the rods on, I've yet to figure out a way to get the wrist pins in with the piston "IN" the block. 8-[

And yes...bottom up will work just fine, I've just found it easier to snug down the crank and then line up the rods one at a time, as they're installed from the top. Bottom up will work.

type I wanted to use:
http://www.sears.com/sr/javasr/prod...Automotive+Specialty+Tools&BV_UseBVCookie=Yes

can't slide it off with this kind of tool ... if I use the plier type I probably can manage the bottom side to top...

There should be an allen head on both sides of the compressor. Use the end of the compressor with the most "tool" surface on it...the long end :-s , and slide the rod and piston combo in from that end, so that the rod in now hanging out the bottom end of the compressor. You'll want to have the piston combo as far to the top edge of the compressor as possible (just so that the first ring is barely in the tool) and then slide it up into the cylinder. If the cylinder skirts are hitting the tool and you have not got the piston (all rings) in, you will have to come from the top.
 
so... I take the long end and face it downward towards the crank and use the short buisness end of the tool to gradually move the piston in to the cylinder... is that correct?

As long as you can slide the compressor far enough inside the cylinder, that your rings are exiting the compressor (either end) and into the cylinder, it makes no difference which end you use, unless that one is designed differently than mine. Mine work either way. Be sure to oil up the rings before you put the piston ass. into the compressor, it helps things slide out and in. (I'm sure someone out there has a sh1t eating grin on their face) :-D
 
eww... that did sound wrong ... but makes sense to me. I just want to get these things back in the engine so I can get the engine back together and onto tuning it up ... this delay is so annoying
