    Shim kits for valves?

    Is the spreadsheet just an interactive version of the chart that's in the shop manuals? Looks like the 2-valve bikes all have the same chart, this is from my 450 manual but it is identical to the 650 and 1000 manuals I looked at.

    BOTM photo submissions needed NOW

    I don't have anything to submit now, but will once I get my 450 hopefully repaired before the start of summer. Always fun to see people's bikes and it is impressive how long BOTW has been going. I hope some others take the time to frame up a good picture on a nice day!

    '82 GS450 Engine Chatter - Cam Related?

    Hopefully this is the last update on the matter. I replaced the tensioner with a decent looking one from eBay. Immediately I could tell the knob had more spring tension than mine. I'm guessing I missed a turn of tension when replacing the oil seal, which didn't give the tensioner enough...

    '82 GS450 Engine Chatter - Cam Related?

    Bah, had the chatter return last night. When I had the tensioner disassembled to replace the oil seal the spring and push rod were in fine shape, the problem must be in the knob assembly. That isn't listed as a separate part on the fiche so I guess a complete replacement is in order. The...

    '82 GS450 Engine Chatter - Cam Related?

    I loosened the set screw and the chatter didn't return, I'll roll with it as is for now. Might be too soon to say the problem is eliminated but if it happens again at least I know the tensioner is the source. Might be a good idea to strap a 12mm wrench and screwdriver somewhere in case I need to...

    '82 GS450 Engine Chatter - Cam Related?

    Next weekend... one month, what's the difference? ;) That was some really impressive detective work guys. Yes I did rebuild the tensioner using bwringer's guide. After reassembly the mechanism seemed to work as intended but the bike needed more work before I could ride enough to uncover this...

    '82 GS450 Engine Chatter - Cam Related?

    Something with the tach gear makes sense but when I disassembled it nothing looked scored or gave an indication of something being off. It came apart no problem (once I pried loose #20 on the fiche from the head, that was pretty stubborn) and everything fit back together without a fight. I...

    '82 GS450 Engine Chatter - Cam Related?

    Hi everyone, my GS450 was running very well (I guess it still kinda does, fires right up and will run and rev while making this chatter) and then it started a very loud and tactile ticking when running. Definitely sounds like it is coming from the head/cams and it causes the cam chain tensioner...

    GS450 Official Service Manual PDF

    I tried e-mailing it using the address on his site, but it bounced as spam (which is weird, I use Gmail). If anyone is in touch with him it would be great to get this on the site.

    VG's Picture-Heavy 1982 GS450TXZ Journal

    Cap on and ready to try finding the best idle and syncing. I went a little fancy on my fuel supply. Got a generic coolant reservoir and since I wasn't about to remove the fuel line from the carbs I used a barbed shutoff switch to splice the normal fuel line with a new length. Worked pretty...

    VG's Picture-Heavy 1982 GS450TXZ Journal

    Cue March. Warmer weather is coming and I wanted to get things running. I decided that the best way to do that was to return the intake to the stock airbox instead of chasing carburation gremlins with the pods. I reached out to Bill about rejetting my carbs back to stock and he said send them...

    VG's Picture-Heavy 1982 GS450TXZ Journal

    Back to the bike. It was painstaking to remove the gasket without knocking material into the engine. But I did get it pretty clean I opted for the tappet tool instead of the zip tie method. My two exhaust valves were tight. So they got new 2.50mm shims from the original 2.55x size...

    VG's Picture-Heavy 1982 GS450TXZ Journal

    This was the big surprise. When first looking at my bike I didn't think much of the air intake. But by now I realized these K&N pods were not original. I somehow doubt the man I bought it from put these on so they're over 10 years old. The bike ran ok so there was an attempt to rejet. These will...

    VG's Picture-Heavy 1982 GS450TXZ Journal

    I've had my 1982 GS450TXZ for about a year now. It is my first motorcycle and this thread will be a sort of pictorial journal of the work I've done. While it had clearly been taken care of, the more I worked on it the more I realized that it didn't get all of the maintenance it should have over...

    GS450 Official Service Manual PDF

    I hope everyone is well and keeping occupied. Although I have hardly posted, these forums have been an awesome resource while I've been working on my GS450 over the past year. One thing that was a problem was the rarity of the official service manual. The Clymer manual is fine but it doesn't...

    GS450 Valve Cover Stuck

    Thanks for the help! A combination of everything got it off. I wet the perimeter with WD40 then used a sharp chisel and a mallet to set a score into the gasket in a couple of places. I tapped a flat and firm putty knife into the various scores until one started making progress along the seam...

    GS450 Valve Cover Stuck

    I've been working on my recently acquired '82 GS450 and sent my carbs to Bill for rebuilding. Figured it would be a good opportunity to check my valve clearances since I haven't looked at them yet. Removed the bolts and it isn't budging. I don't think the cover has ever been off. Before I start...

    New '82 GS450T Owner, My First Bike

    Thanks everyone! Glad to see some other Ohioans here. I appreciate the advice. The Earl's lines look pretty easy to assemble, I think I'll go with those. My dad recently bought a Harley Street Glide after riding a Yamaha V-Star 1100 for almost 10 years.

    New '82 GS450T Owner, My First Bike

    Hi Everyone! I have always been a fan of classic Japanese bikes and over the winter finally caught the bug to give owning my own a shot. My dad has ridden for a while now and kept suggesting I get a motorcycle to ride with him, so I'm looking forward to learning and joining him on the road. I...
