GS1150 Rebuild

So I have started my 1986 GS1150 rebuild. Question is I am sourcing the base and head gasket and they are giving two cylinder options. One is 101424 or 101425- where do I find that information? Same with the crankcase 102247- or 102248-?
Any help would be appreciated.

Cheers
Paul
 
Base gasket part # 11241-00A02
Cylinder gasket part # 11141-00A03

These are the correct part numbers for the 86 1150
 
Thanks Chef.
I am not sure why they list the different numbers?
So the engine will consist of 86 cases, 85 cylinders and transmission and 86 head.
Also is it better to get the oem timing chain as well, I am guessing its continuous?

Cheers
Paul

Might as well get a HD chain for it while you are in there, cheaper than OEM I believe

Thanks guys.
This will be my first complete tear down. I have done new rings and hone in the past.
A little nervous swapping over transmissions from the 85 cases to the 86 cases. Hopefully I don't screw it up. I do have my shop manual.

I have split cases 5 times or so. Orginization is key, make sure the crank seal stays straight, as soon as the cases are together, put vice grips on the shift shaft and make sure it shifts before tightening it down. Threebond dries fairly quickly, at least mine does, so it needs to be applied and bolts torqued fairly quickly before it dries too much. Oh ya, it stinks too, it will give you a buzz unless you are well ventilated:o:eek:
 
Make sure the shifter forks are in the right slots, the o-ring is in the main oil pickup and the spring is on the shifter drum.
 
Paul, feel free to call me at 714--356-7845 if you have any questions. I will be glad to help & have been building Suzuki engines for over 30 years. Ray.
 
Thanks Ray.
I have seen your posts over the years and you are definatly the engine guru.
I split the 85 cases over the weekend to start swapping things over to the 86 cases. Reason I am doing this is because the 85 cases have chunks missing where it looks like it was dropped on the ignition cover.
Everything inside looks good, gears, crank etc. Looks like it was redone at some time, even has a DID timing chain installed.
Have to clean the 86 cases this week.

Now to put my parts list together:
-new crankshaft seals (oem) should I replace them?
-transmission seals (plugs)?
-base/head gasket and o-rings (oem)
-rings (oem)

Cheers
Paul
 
What are you going to do with the 85 cases? I could use them if you want to do some trading. Ray.
 
Ray:

I was going to keep them and see if I could get them welded up and refinished. Just wanted to swap them so I can ride the bike for now and also get my head around these engines a little.

Does anybody have a source for clear microfiches for the 1150? On the crankcase the lower part is almost unreadable. That is for Cyclepartsnation, Alpha sports, Mr Cycle,Boulevard Suzuki.

Cheers
Paul
 
Thanks John, that one is alot clearer.

Does anybody know what this part is?
It fell out when I split the cases?

Cheers
Paul
 
It looks like the gear/neutral indicator pin that has a spring behind it. Fits on the sprocket side under the cover.
 
Another silly question.
Seeing as the bore is 74mm (2.91") will a 3" flex hone be good enough or does it need to be a little bigger to generate more force against the cylinder?
In the past I have used the 3 stone hones but the flex look a little easier to use?

Cheers
Paul
 
Sorry one more, what grit should I get for new rings. looks like the cylinders just need a de-glaze. I have used 320 in the past but i can get a 600 as well, too fine?

Cheers
Paul
 
320 is good. Not sure but I think that 3" hone should be fine. Use lots of oil and wash well afterwards.

The neutral indicator pin is captured by an electrical switch/indicator that bolts to the engine. I'd store that little pin and the spring until you put the engine back into the chassis so they don't get lost.
