Ah yes, I'm starting to remember now. I knew there was a spacer involved.

530 Chain Conversion - sprocket size & Chain length

Ah yes, I'm starting to remember now. I knew there was a spacer involved.
But why would you ever need to buy a spacer with a 630 to 530 conversion? If the sprokects are the same thickness, wouldn't you just reuse whatever spacer is currently between the nut and sprocket? And if there's no spacer from the factory, you shouldn't need one at all.
I'll still trying to get the cover off the front sprocket. Forgot how hard the old "phillips" screws are to remove. Hoping another evening or two with PB Blaster will do the trick.

I just did this conversion on my 78 Gs1000. The stock countershaft sprocket has a heavy shoulder on the side that faces away from the motor. That's what the spacer makes up for. If the screw heads are stripped, drill the heads off with a 15/64 drill bit.

Is this thread/mod about turning a shafty into a bike with a chain drive??

Nope, it's about changing the chain/sprocket size on a GS1000 from the stock 630 to the much more common 530 size. 530 is more than strong enough, it's lighter, cheaper and offers more gearing choices and a vastly bigger selection of chain brand/type/quality options.

I just received my JT sprockets and JT chain (Expert siries X1R X-ring Drive Chain) I ordered them from Z1 Enterprises. $150.59 to my door.(including shipping) I went with a 50 tooth rear sprocket and a 18 tooth front sprocket with 116 links of 530 chain. Check one more thing off my list
Oh, for reference this is for a 1979 GS1000e

This thread reminds me I need to complete this task. YES, there is a SPACER that was included in my order from Z1 for my "T". I also ordered OEM nut and washer.

Mine is still sitting on the shelf too! I might get to it this summer, along with the oil change and perhaps some new rubber.

So I have my 530 chain kit from Z1. It looks pretty much like picture a couple posts down. It has 18x49 sprockets and 116 link chain. When I put the chain on with adjusters in the middle, the chain looks very loose. I am hesitant to cut any links, but but before I install and rivet the master link. I that I would ask for opinions. I can post a picture if that is any help.
You might want to try pushing the wheel as far forward as possible after backing off the adjusters, then pull the chain tight by hand and look to see if you can remove two more links.

I'll do that and report back before cutting anything. I was reading another thread where the person had 50 instead of 49 rear sprocket and cut one link that the hainm was too short. Will go back to the chain after I finish putting the clutch cover back on. This is on a GS1000S it it makes any difference.
That was probably me. Remember that when you take the bike off the center stand your chain slack tightens by about a full inch or more. I wonder why they sent you a 49 rear when the 18/50 set gives as close as you can to the 15/42 combo. Works out an decrease in RPM of only around 40 at 60 MPH. 18/49 would give you around 250 RPM decrease. Just guessing at that from the calcs in my head. LOL. You might want to actually run the numbers. I'd probably run the chain as is for now and at some point when you run out of adjustment remove the links then.

With this thread being as informative as it is I figured this was a good place to pose the question as to if I have this correct... 81 Gs1100e is the bike and I just wanted to make sure I have the sequence correct. I took off the 630 front and it was nut, lock washer, a large spacer, sprocket and finally the collar in the seal.
I replaced with these items from the outside for a 530 conversion in this order... nut, lock washer, 6mm spacer, sprocket and again the same collar in the seal against the motor. This is correct is it not? I just want to clarify for my piece of mind. One of the pics shows the large spacer that came off and I did not reuse. Thank you guys....

Yes that's correct. The original OEM sprockets had a raised area on the outside (nut side) to accomodate some rubber chain dampers. Most after market sprockets do not have that and require the spacer to make up the difference as the countershaft doesn't have enough threads to properly tighten the nut. This applies to both the aftermarket 530 and 630 sprockets as the sprocket and chain width are the same.
