    Adjusting clearances on all four intake valves by removing cam shaft?

    Thanks. Now the conundrum is if I should do that at: 1. When the "1" arrow mark on the exhaust cam is pointed forward. The cam chain is relatively tight (i.e. less available slack), but this is the official assembly reference -or- 2. Find a spot in the cycle where the cam chain is relatively...

    Adjusting clearances on all four intake valves by removing cam shaft?

    @Gorminrider - Are you saying that if the tensioner is currently installed correctly, the camshafts could be removed without having to remove and reset the tensioner? I'm asking because I'm now in the gasket cleaning phase (a.k.a petrified gasket hell) and it *might* be easier if the camshafts...

    GS850GL: Where to start to learn how to tune carbs?

    A few more things to check in the long list ... 1. What is the setting for the air/fuel mixture screws? 2.5 turns out seems to be the norm for the Mikuni's on these bikes. 2. Are the intake rubbers and related orings in good condition? Still supple, no cracks, etc. If not, they may be letting...

    shim club

    Anyone have a true 2.6mm shim they want to exchange for cash or other size shims? I have several at 2.64, 2.7, and up.

    Adjusting clearances on all four intake valves by removing cam shaft?

    thanks all. I found an old Suzi tool and it worked fine on the intakes, which is all I really needed. Current state is: Exhaust - All four at .05-.06 using existing shims. On the low side of spec, especially for exhaust, but I didn't change any Intake - Adjusted all four. #1, 3, and 4 now in...

    '83 GS650L rescue

    Splines on final drive and various related and mating parts looking good. Always a relief

    Adjusting clearances on all four intake valves by removing cam shaft?

    Thanks for the hint, plus i've got a bunch of spare shims, so coin approach probably not needed. I'm pretty sure they all just need to go one size thinner. A .02 feeler gauge fit under one and all four bucket/shims turn easily as the exhaust ports with no contact. I realize turning still...

    GS850GL: Where to start to learn how to tune carbs?

    The Newbie Mistakes thread is certainly a good reference. Given the info above describing behavior when closing the choke, the most likely issues are: 1. Idle circuit passages didn't get fully clean during the recent carb cleaning. Ultrasonic cleaning and compressed air are the best/only...

    shim club

    I'm about to adjust the four intake clearances. I have a stockpile of seven (7) 29.5 shims, but if they don't fit the bill I'll be in contact.

    Adjusting clearances on all four intake valves by removing cam shaft?

    Thanks for thinking that through. Accessing the tensioner for adjusting or resetting is difficult with carbs in place, so I'll go with the normal 1by1 method.

    Adjusting clearances on all four intake valves by removing cam shaft?

    Checking valve clearances on my '83 650L project led to all four exhaust at .05-.06 (within spec) and all four intakes at less than .02 (too tight). Since it's all four on the same shaft, is it possible/reasonable to release the intake cam shaft and do them all at once? If so, should I release...

    Electrical system is awake...next step drain carbs or full clean?

    I used the ebay source that has been mentioned in other threads about oring availability. Delivery and quality seem fine, but it is difficult to differentiate between some of the rings that have similar but slightly different sizes. Image below shows the combined orings for the fuel tee, fuel...

    Electrical system is awake...next step drain carbs or full clean?

    I guess every bike and mechanic is different. Some are more patient & methodical than others, seems like I fall into the less patient end of the spectrum. For my current $250 GS650L project, I did the test fire yesterday after cleaning the carbs and replacing the air filter, but not checking...

    '83 GS650L rescue

    Update: After buying backup carbs to replace #1&4 who had immovable slides, the carbs now cleaned, sync'd, and back on the bike. Successful test start yesterday - starts, idles, revs up and comes down, shifts through gears, etc. Next need to clean out tank, check valve clearances, tires, and...

    Electrical system is awake...next step drain carbs or full clean?

    For me, the nastiest part of checking valve clearances is getting the petrified gasket material off the valve cover and cyl head. That is my least favorite part of rescuing these old bikes, which is why I test for basic engine firing before doing the valve check.

    Electrical system is awake...next step drain carbs or full clean?

    Count me as another vote in the "pull the carbs and give them a proper cleaning" category. Based on other info, it is extremely likely the idle circuit passages and tiny jet holes are clogged. I've tried to start some without carb cleaning, but it's super rare you'll get that lucky...

    Gs650 81 to 82 carbs interchangeable?

    That's what I thought, thanks for the confirmation. This carb rack will be far from perfect/factory since: - #1 has aftermarket #170 pilot air jet and the outlet port beneath the mixture screw has been enlarged by previous owner. Fiddling with mixture screw definitely required, currently 1.5...

    Gs650 81 to 82 carbs interchangeable?

    Speaking of jets for these carbs, how big of a difference will one size in the pilot air jet make? Specifically, going from #160 to #170 in 2 of the 4 carbs and assuming all other jets, filters, and exhaust are the factory parts. Asking purely for convenience of using parts on hand, not for any...
