Hey guyz!

There is no way that the mechanic (I think so if I got it right) messed up the timing becouse he only adjusted the clearance!! He didn't remove the cams or something. According to the quoted post!! So it must be the a/f mixture!
Enough with the theory. Sorry for all the fuzz! I would like to thank you all for being so kind with yr help!! I'll start wearing my woking rob tomorrow afternoon or Sat morning and get the jobs done!! Will post pictures!!

All they need to do is turn it to tdc rear cylinder (no need to touch the front one) with the cams pointing up and towards each other, then remove the cam caps and cams, then holding the cam chain loosely to stop it jamming round the crankshaft, rotate the engine anticlockwise one full turn at the crank, until RT is lined up once more.
Then fit the cams, with lobes pointing up and towards each other as before.

:wink: As for the backfiring problem solved by connecting the rubber hose under the tank! Backfiring comes from:

-cut sub-pressure rubber tube
-carburator total wrong synch, A/F mixture
-Spark plug problem
-Spark plug wire or coils!

Hope this helps!
Good afternoon everyone!

Valve clearances adjustments are done by shim & bucket - rather than by screw & locknut - so some dismantling needs to be done if he changed a shim and potentially done wrong if they didn't know what they were doing/have little/or no experience of working in VTR.

See page 125+ in the PDF Honda service manual> Cylinder Head/Valve 8-12 > http://www.vtr1000.org/phpBB3/viewtopic ... 31&t=18025

Have you checked all the lines underneath the tank have been put back correctly?

Cams word have been removed to do the head gasket.

Good morning!

Friday today and I can't wait fixing my bike!. I'll start with carbs, cleaning, checking jets, jet adjustments (screws) etc. Therefore I'd like to ask a question. Do I have to change the gaskets? Mechanic didn't, just covered with the same gaskets and sealant.

No need at all to use sealant on the carbs .
Check all passages for sealant blockages

Well,

Must I replace the head gaskets if I open the cylinder heads?

You only need to add a dab of silicone gasket to the help seat the rubber seal on the cam covers if you remove them to check the timing. Make sure you can get the timing cover cap off the alternator cover.

Not sure why you want to dismantle the head when all you need to do is to check the timing is correct. Check the manual which I linked to earlier in the thread. And if you are replacing the CCT use the illustrated guide in the workshop knowledgebase.

I have to check, if the camshafts position (readings on camshaft sprockets) comply with the the crankshaft position (readings on the little window located at the alternator cover).

All that to check if the bike had been timed wrong 180' off. I hope not!! :crazy:

If your going to check for timing being 180 out the timing marks will all line up correctly. So it's not something you can visually check for. Follow the instructions in this post http://www.vtr1000.org/phpBB3/viewtopic ... 34#p300720 there is no harm in trying. You can put the timing 180 without doing any damage. One of two things will happen, you will either put it 180 out or put it back to as it should be.

Make sure you know what your doing with the timing!!!!

Good day everyone!

I'll check the timing as I'll change the CCT. I must say that I'm afraid a little but it'll be an interesting work. W/o your help and the help of manuals it'd be difficult as heck! So cheers everybody and wish me luck for Saturday's works! :wave: :beer:

Work List for Sat 26/10/2013:
-Carburator Removal
-Engine's CCT replacement
-Both cylinder head cover removal and timing check
-Camshaft sprocket adjustment (if need any)
-Head gasket placement for both cyl with new ones
-carburator de-assembly, clean, jet adjustment
-carburator assembly, placement
-TESTING-ADJ-TESTING-ADJ

AND THEN riding!
