    Psyching myself up for the top end - any veteran eyes up to read borescope pictures?

    May be some photos of where the oil is leaking? Also if the 6 mm to cam cover bolt holes are stripped, the correct (best and permanent) fix is to use a thread insert. You do need all of these bolts torqued evenly to the correct torque for the gasket to work as intended. You can do thread...

    Psyching myself up for the top end - any veteran eyes up to read borescope pictures?

    Hi Seinwave My two cents is that you want to be 100% certain of the source of the oil leaks. Disturbing good joints that aren't leaking can lead to that joint leaking. Including if you aren't fastidious in your gasket replacement. The likelihood that it the leak has just started, its coming...

    Engine Knock

    No, it's not damaging, just annoying. It can be eliminated but requires custom matching to fit a shim. I think there is a thread about how to do this. The sound is one (or both) camshafts sliding sideways as they rotate at low speed due to a little too much clearance. The sideways oscillation...

    Buying Tires - Front vs Rear

    I was told by a local tyre dealer that with bias ply tyres (and it may be true of radials), the way the plys are laid in the carcass effects tyre/tread deformation at the contact patch under load. Effectively the tyre is better at transmitting force in one direction than the other. The advice...

    Just got a 1982 GS650G have ?

    Diesel oils will work. Some folks like them because they have higher ZDDP additive levels. ZDDP forms a localised physical anti scuff coating stopping metal to metal contact in extreme low lubricant , high-pressure, high-temperature contact points. So high ZDDP is desirable in air-cooled...

    They're all really good and why they are a personal favorite isn't a mystery. It's come down to a toss up for me between Gustovh and Rich82GS750TZ. Both would make great album cover art works (remember them?). Really tough, but I'm throwing my vote to Rich.

    Why does intake leak cause hanging high idle ?

    Not labor the point, but this doesn't explain why leaning out a fuel screw on carbs without air leaks also causes a hanging idle... Your not adding any more air, your reducing the amount of fuel... which suggests its the leanness causing the hanging idle rather than extra air. Thoughts?

    Sorry time difference... Thanks for the votes and the theme is 'favourite' or 'favorite' for the USA. Can be anything you like (pun intended).

    I am looking for some help with my '83 GS1100E fork setup using emulators

    I stand corrected, although the oil passes back through the emulator the check valve allows free passage of the oil to be metered by the rebound orifice. Which makes sense as the rebound extension speed is governed by the fork spring so is for all intents and purposes constant. No variation in...

    Bike randomly died while riding.

    Did you have the throttle wide open? Seems strange that they are within 10 psi of each other and all are equally low; service limit is 100 psi, - recommended range from the workshop manual is 128 - 170 psi.

    I am looking for some help with my '83 GS1100E fork setup using emulators

    My Gold Valve Cartridge Emulators made with 3 extra sets of springs with different compression rates for larger tuning changes. The nut is more of a vernier adjustment of pre-load on the spring. There no shim stack on the 3 sets I've fitted and it's the valve spring and preload nut/screw that...

    Why does intake leak cause hanging high idle ?

    Extra air bleeding into the idle mix from a leak makes it lean and lean mixtures burn slower than a correct mixture. A rich also mixture burns slower too. This is why you can tune for highest idle on the mixture screw to set a correct idle mixture. With a rich mixture the extra fuel cools the...

    Identifying seal 81 750

    Just because I've never seen one doesn't mean it's not meant to be there. Its interesting as it sits underneath and is covered by the gasket (carbs inverted for reassembly) so what does it seal? I've never had a problem with leakage or starting. As far as I know the choke plungers are the...

    Identifying seal 81 750

    I've never seen a seal in that position. There is a metal blanking plug which appears to be related to the machining process during manufacture. The float bowl gasket seals this area (which the fuel pick up/air bleed for the choke circuit). I think a PO may have tried to 'improve' sealing... The...
