Thanks for the video . I’m about to do my valves also on my 97 1200S . That blue stuff you put on under the half circles of the gasket , is that the same thing as Lock-tite?
The manual says to use the special Suzuki sealant . Nobody seems to know what it actually is the equivalent of . I was thinking of using something I already have , Permatex Ultra Black , which is a high temperature RTV gasket sealer .
We’re you happy with the sealant you used ?
Good idea to make sure all engine openings are covered to avoid unwanted stuff going down .

Hi Willy, thank you for the nice words. Don't know, if you mean a silicone sealant, or thread locker. This is a thread locker and it works very well. But you could use a high temperature and oil friendly silicone as well. Loctite is making both of them. Just use something. Good luck

[@willyf6172]

@@REBUILDLab Yes , I meant lock-title thread locker , if that is what you used . I was thinking of using the Permatex stuff because I already have it . Never heard of thread locker being used . One concern I seen brought up with sealants is if you put too much on , it squishing out on the inside unseen . And the a piece of that coming loose and circulating inside your engine , where it could block an oil passage way .
The thread locker should not be a risk for that , so that is why your idea interests me .

[@REBUILDLab]

Hi Willy, yes, you're correct on this. If I would use a silicone, it would be a very tiny layer exactly because of the risk you just described. A medium thread locker is kind of soft glue, that should be just the right thing for this purpose. Btw. the valve cover sealing is over 15 years old and still seals ok, the locker was applied only on the sphere shapes.

What is that noise at 3:14 during turning the rear wheel?

[@REBUILDLab]

It's the noise of secondary chain hits the sprocket and via the transmission moves the internal parts of the engine. There was a 5-th gear set in the gearbox to move the engine.

[@grabir01]

If there is little to no air gap, then adjust. Otherwise, leave then alone.

[@REBUILDLab]

well, yes, if the clearance is too little, it is dangerous...should be adjusted, you're right

[@grabir01]

@@REBUILDLab Are you still doing Bandits?

[@REBUILDLab]

@@grabir01 Well I have mine, driving it doing maintenance on it... like that. Having it for 15 years or so now ... But it's not the only bike I have. Why?

[@willyf6172]

Just watched your video again and noticed you state that the exhaust clearance is .18 - .32 mm . According to the Haynes manual the spec is .18- .23 mm . At .25 you are too loose . And just checked the factory service manual and those specs are the same. .23 mm is the maximum for the exhaust valves .

[@REBUILDLab]

Thanks have to check it. Anyway - too loose is better than too tight. The engine is working fineust ok.

[@REBUILDLab]

Checked it - you are right. It should be 0.18 - 0.23. Added a correction comment for this in the video... Thanks for the hint

[@willyf6172]

@@REBUILDLab good was not trying to be argumentative , but a correction was required . Others may have seen it and ignored it . I think if you are to loose it won’t hurt your engine , but you may lose a little power , due to the valves opening slightly later than they should .
On a different note ,have you had any oil leaks with the lock-tite?

[@REBUILDLab]

@@willyf6172 I'm glad for the correction, it is of course not ok to use false data. Luck was it wasn't the other way around. Regarding your qiestion, the rubber sealings are 15 years old at least and a bit harder. So the thread locker was used and it holds pretty good. No leaks so far...

[@99Barmaley]

Выглядит так, как будто он свое уже проехал.

[@REBUILDLab]

Sorry my friend, don't understand your language. Anyway, thanks for the comment.
