1984 VF500F with 86 engine complete rebuild

Another shot of the R F cam lobe

 

Yes Capt all cams have offset lobes but with the cam gear in place it' compressing the valves. I suppose I could drill new holes in the cam gear and forget about the alignment marks and just align it visually.

 

Not sure I understand what you are trying so say.

Oof. No. Just no.


I suspect something got mixed up between engines or installed/timed incorrectly. Or a combo of the two. But to be honest, I really don't know for sure, as the pics and descriptions are not helping.

 

OK here let me show you . This is a view of about where the cam should be.
Left Front

Right front

There is plenty of space to adjust the valves.

 

No. That is wrong and not how/where the cams should be to adjust the valves. I still can't say whether your cams are timed properly, but I can say your method for positioning the cams for adjusting lash is wrong.

Show me where in the SM is states to use any "T" mark to adjust the valves on an 86. 84/85 use the "TR" and "TF" marks on the flywheel, but that is still not necessary if you note when the cam lobes are opposite to the rockers.

 

THIS is a view where the cam should be.

 

I'm too tired to do anymore today but tomorrow I'll probably pull the cam out and take pictures of the T1 mark and all the other cam positions. Thanks for helping out

 

Marks on the cam sprockets are for cam installation and timing. Not for position for checking valves.

 

any explanations welcome: whats the deal with the long headbolts with very wide thread pitch ?? 'splain me the engineering there.

never saw those until i had to take my vtr250 engine apart, dont understand the bolts.

 

S-Man, both the VTR250 and the VF500F /C have those same weird spiral wind "threads" on the head bolts.

Pure speculation but they may have something to do with how much the bolt "yields" under tension. Like when you torque them down.

Many head bolts are a one time use only design, but if you can't get new ones you use the old ones! I am not sure how much the stretch anyway at the low torque needed for the. Just 10 cents worth, LOL.

 

Thanks to the Captain I got my valves adjusted

I have a video made on youtube that I could share if I knew how. I've tried the embed feature but no sucess.

 

You have to host it somewhere (like uploading to YouTube), then you can use the "Share" button to get a link to embed.

And good job.

and this is how I tried to embed

 

I think it is because you created a YouTube "Short", not a Video.

 

If it is a short video they are automatically listed as short. Anyway can you see the video

 

Not necessarily the actual "length". How it was created in the first place. You can see right in your link

Sounds pretty good and crisp throttle response. I like how it settles right back down into an idle too.

That's gotta feel good.

 

Youtube does it automatically. Now owned by Google, if you search the internet for "can I change a youtube short to a regular video" you'll seewhat I'm talking about.

 

Got it. Had never happened to me.

 

After all this time you bet it feels good, and thanks to you. you made it happen
