Well, I don't really like the idea of RTV on an adjustable part to keep it from leaking. I won't be able to adjust it the way it is and I'd have to keep gooping it up to keep it from leaking.

If I could find the whole adjuster assembly, I'd just swap the whole thing, adjust it, and be done with it.

Anyone know where parts like this can be found semi-easily?

My 78 XS11 has some RTV on the end of the adjuster that has been there for many years to stop a slow seep. Works fine, don't worry about it.
BTW, good to see another MN member. I was just up there last week to run Hwy 1 from Ely to the north shore. Great ride. You might want to check out www.xs11.com/ for more info and some excellent tech advice.

It's not threaded. It's just a little plastic plug that stops dirt getting into the plunger/shaft area. It just pushes in. If a new one is available the I wouldn't expect it to cost more than a buck.

If new is not available then I'm sure something could be found/made to replace it. Try a rubber place who have cap ends for tube type furniture. Around 15mm diameter I think.

Thanks for all the advice. I really need to adjust the cam chain, but I'm afraid to take off all the RTV and find out it leaks really bad.

I'm sure there's a better fix for the leak than filling it with RTV. If anyone has any parts laying around, I'd be interested. Drop me a line here or e-mail me.

2fast, I've done the Hwy 1 trip a few times. It's a great little ride on a nice day. I'm on XS11.com too, but they're geared more toward XS bikes. I like it here where people mainly deal in the XJ's.

Anyway, thanks again for all the replies. Much appreciated!

You won't know what the problem is till you scrape that goop off. If the plastic cap is still undr there then it's an easy fix. Just knock it out and put a light coat of rtv in there before replacing the cap. Also check the rubber o-ring under the locknut. Apart from that the only other leak source is the face gasket.

If it was me I'd take it off and give it a good clean. One danger of cam chain tensioners is overtightening them and having the housing split. DAMHIKT. PO might have done this and put RTV over the crack. If this is the case then get a replacement pronto as the tensioner will be floating around, not locked in position.

Does anyone know it the 85 XJ700 is a manual tentioner or automatic?

Thanks

I just found this thread and found it to be exactly what I needed to do to my #1 1100. The valve train was making some noise and I had just checked the valve clearance and it was still noisey. I did the adjustment and now no noise. It also seems to run better. Not sure if the chain is loose if it retards the valve timing. Just one more little thing done to make my bike run better.
Seems like there are a few who are asking about valve train noise these last few weeks. Maybe they should check there tentioners to see if their chains are loose and making that noise.

In my previous post I stated that my search results said "Post Not Found"
Turns out I was clicking the wrong search button...
I humbly accept my spot in the idiot line!

Just picked up my new (old 1982) yam xj 650.
The rattle near the front of the engine makes me wonder about the tightness of the chain.
Is this a manual or hydraulic adjuster?
Thanks for any help.
