Doing the tappet thing tommorow in my brothers workshop. (He is a motorcyle mechanic in south London. )Anybody have any helpfull advice/ tips things to look out for? Many Thanks... Would it be worth doing a photo shoot and how to for anyone?
Cheers.

can't hurt to take some photos, its pretty straight forward, the only tip would be to unbolt the cam in stages so you don't put too much stress on it as they can crack. but thats common knowledeg for mechanics! go for it!

Ok, so I got to my brother's workshop, (he shares workshop with car mechanic) car mechanic was working today (not usually on sat) and he took over! did the job in about 20 mins with interuptions!
no tick tick tappets any more...... however we seem to have upset something slightly as the idle hunts down, then jumps up again occasionaly.....ISV need cleaning? The timing is ok and all vacuum hoses seem fine as well.....?
Finished refurb and polish on the alloys today as well, here is a pic... getting tyres on monday...Eage F1's.

Yes, looked easy, make sure you are carefull about marking the timing, and undo the cam shaft bolts in the correct sequence, then use a torque wrench to re-torque them again. A usefull tip i guess is to remove the air box completely which he did, to make things more accessable. Oh and a good idea to get a new cam cover gasket.

i'd take your throttle body off and give that a good shot of brake cleaner, if you've had sh!tty oily stuff come throught the isv it may be stick ing the butterfly's and be constantly trying to correct its self., easy job, four 6mm allen head bolts. while your at it i'd clean your isv and check the condition of the crankcase breather and the bung that sits in the rocker cover as these are prone to splits which can also affect your idle.

wheels look sweet by the way! :wink:

Hmmm.. Thanks Joe. Will do when have time, temporarily fixed problem a little by increasing idle speed, whixh seems to have stopped the revs dropping off, and then hunting back up.
The throttle body did look quite clean, apart from some gunk from one of the breathers near the air inlet (forget which).
The rockercover bung looks fine, I did check that.
:smiley:

Check the idle switch, its underneath the throttle body. With the engine off make sure you hear a distinct click when the throttle is closed. I had to give mine a couple of taps with a hammer cos the bolts are a nightmare to get to!
Does it still haunt with the ISV disconnected? Also did you reset the ecu? Unplug blue sensor when the engine is up to temp, rev the engine 3 times over 3k then set up the CO and plug back in :)

Thanks. Read about the ECU reset last night in the normally useless Haynes. Will do all the suggestions at the weekend. Ta.
