Hi Gixer1460, I am hoping that the 530 sprocket diameters are not too significantly different from the 630 ones. The tooth count on the current 630 front sprocket is 15, the 530 is 17 so should bring it back to almost the same as a 630. The rear 630 is 42 teeth and the 530 is 48 so I will check the issue as you mentioned but I am thinking the extra teeth might not reduce the diameters as you mention. Again I will check this when I get the sprokets delivered. Cheers Steve

Hi Baz, Good point. I will measure the position of the 630 front sprocket and make sure that it is the same as the new 530 sprocket. And make sure it is all aligned to the rear sprocket. I did think it might need a bit more than simply replacing the 630 to 530 stuff. Steve

Thanks Mike, I will go ahead.

The final drive chain on my GS1000 is needing replacement along with both front and rear sprockets. But wait! I have read that upgrading to a 530 chain has benefits? These are: less weight - Less energy loss - Todays chain technology means the 530 chains of today are better than the old 630 technology - Less transmission stress and cheaper - lasts just as long or even longer (the less mechanical weight thing) Bikes manufactured today don't use 630 chains so perhaps this answers my question So, upgrading to 530 seems like a no brainer..... What do you think? PS, Just in case a real live Malcome answers, yes, the upgrade will have 530 sprockets too. Cheers, Steve

Same situation here, I am looking for 59600-49810, nothing anywhere. Steve

Thanks Mike and Fazz, I will look further for a rivet link chain and splitter online. At least it's been done before so not impossible todo. Cheers Steve

Hi, I am thinking of replaceing the cam chain on my GS1000 and wondered if there was a chain supplied with a split rivet link. I would prefer not to have to strip the engine completely to thread a chain over the crank and rebuild the whole engine as would be required with a continous chain. My question would be, are there split chain kits for a riveted link (I dont want a clipped link) and if so, where can I get one. Otherwise it's a complete engine strip. Thanks. Steve

Thanks Fazz, I will give Allens a try tomorrow. Any idea what these carbs are called, are they the VM series? Or what are they, see picture on first post. Cheers Steve

HI, I have a set of Mikuni Kogyo carbs fitted to my GS1000ST. I have an issue finding a UK based supplier who has o rings, specifically the ones on the pilot jet and float valve body. Can any one suggest a supplier who knows Mikuni carbs based in the UK? As this bike is a grey import, it's difficult locating parts specific to this bike and would appreciate some info on who I can call to get parts. I seem to find plenty of suppliers who know little about these carbs. The specific model of carb, stamped on the body is PC 491/20 Any ideas or where I can find a parts diagram for these would be great. Second question - The horns fitted to this bike are the standard Hi and Lo type. The connectors have a O and a Y stamped on them. Any idea if these have a preferred polarity? Cheers Steve

Hi, Just thought I would share this with the forum regarding the cam timing on certain GS1000 models with the cam wheel part number 451. A number of years ago, the top end was serviced and as per the manual, 20 rivets between the cam arrows had been set. Although it was not noticed that the end notches did not face each other as the factory manual was followed. However, the performance was always on the pow side for a 1000cc machine and not much was thought about it until I read recently that cam wheelsd with part numbers 451 should have 19 chain rivets between the arrows. This also lines up the cam end notches so they face each other. I took the cam cover off and found that I had the 451 number on the inlet cam and 490 on the exhaustr cam so today I have adjusted this to 19 rivets. see picture. Thinking about this, the cams have 30 teeth so one tooth measures as 12 camshaft degrees (24 crankshaft degrees!) so I am hoping that this fixes the performance issue. There was never any contact between the valves and pistons so I guess I was lucky, but the factory manual did not have this information documented in their manual and I have only just found this out recently.

Hi TonyGee, Thanks for your reply, you are correct, I have searched the internet and come up with some numbers for the GS1000 series and indeed, T is 1980. When I imported the bike, it was given a X plate which would mean the bike was 81/82 but this was incorrect. Something I had not been too concerned with at the time. However, the bike is not correctly dated by the DVLA and we all know that these machines were not manufactured beyond 1981/82, T being the last GS 1000 models which date to around 1980. I have contacted Suzuki and they have responded with a try again later email as they are not able to do anything with respect to dating until the end of March. I note that the log book also validates it as a V model. This would be a completely different model. The following file from the internet puts the T series as 1980. See attached numbers for GS1000ST. I just need to convince DVLA that it should have a T validation, not a V. Cheers for the response, I will wait and see what Suzuki say, I might get the day it was actually made. Steve

Hi, I have a GS1000ST that I purchased back in 1981/2 in Dubai. I brought the bike back to the UK in 1985 where it was subsequently registered as a 1982 manufactured machine and registered with a 1984 plate 'X'. There is normally a data plate on the frames headstock with all the codes including dates etc but this one is missing. All I have are the 6 digit frame and Engine numbers. Does anyone keep a register or have any idea where I can get the actual date of manufacture of the bike from? I am not sure if Suzuki would be bothered looking this one up, but you never know. The numbers are: Frame GS1000 - 534663 Engine GS1000 - 152035 I believe the bike would have been manufactured about 1980/81, but unable to confirm this. Thanks Steve

Thanks Toni, that list confirms the GS hubs are all 49001 Not important now, I wonder which bike has the 49002? I bought this clutch assembly from a breaker (via Eblag) several years ago so they must have mixed up the parts, Caveat Emptor when buying from breakers, they are unregulated and not really responsible for what you buy and fit. Lesson learned. Cheers all for the help, I can sort this now. Steve

Hi, Sorry for the first post, what was I thinking? I have included a picture. The two clutch hubs have part numbers on the back face, the difference being, the shorter one is -1 and the longer one, -2 other than that the part number for the GS is 21411-49001, I presume the -2 is 49002. The dimensions are all the same except the longer one is approx 4mm longer. The longer Hub has shorter pressure plate attachment spigots and there are some spacers to attach the pressure plate and springs, these would need longer bolts. I just wanted to know which bike the longer -2 hub fits as it is may be incorrect for a GS1000. There is also a steel, riveted back to back driven plate, I don't recognise this in the standard bike and again, wondered if that fits a different machine. Here are some pictures. The Hub on the left is the longer one. Note, I could turn down the longer one to match the shorter hub on the right, has that been done before? Thanks

Hi, Some time ago I bought from Eblag a GS1000 clutch assembly and just stored it away until I needed it. Recently I have had a look at it and the clutch and the center, the driven bit, is about 4mm deeper than the standard clutch appears to be. The question is, what is it from. Can it fit, assuming I have the matching drive basket, the standard GS1000? I could fit an extra plate but under the pressure plate is a steel plate therfore I would have to fit two extra plates that would seem too much. There was a double steel plate, two riveted together, so I wonder if that would be sufficeint. Any advice concerning clutches would be gratefully received. Thanks. Steve
