Hi guys n gal. Does anyone think a difference of 0.0005 of an inch between valve shims will make any noticeable difference to the engine running. I personally dont think so but would value your oppinions anyway. Its just how the shim sizes have worked out. I have no inlets to do. Theyre all in spec and seven exhaust are out on 0.007 of an inch with actually one being 0.0065. When i reshim it brings them all around 0.008 with one at 0.0085. Do u think that odd one at 0.0085 will make a jot of difference ? 🤔🤔🤔
Back in the past when I was an engineer and used to visit a company who made race engines they would get to within a thou 0.001 and be happy.
I doubt very much it would make any difference, tightening a bolt slightly to tight might take up any slack or leaving a bolt to slack might give it a bit more clearance.
If it was my bike, I would be happy.
:agree:

Ye i did think it wouldnt make much odds. Well im gonna stick with it ill throw a few photos too to show the amount of work involved. Showing exhaust cam in then out and spikey timing cog. Also one shows the limited amount of room to work with. But it is doable so when my shims arrive ill post some more 👍👍
I would be happy at that. A slightly larger gap is better as the gaps get smaller as they wear. :clap:
Yep wildy i make you right. Better over than under on these bikes 👍
heard stories of the camshaft position sensor leaking from the o ring seal. Maybe worth a look whilst your in there.
Another thing to consider is the fuel filter. http://www.zggtr.org/index.php?topic=17490.0;topicseen
Ironicaly i have just replaced the o ring n guess what its bloody leaking again. So thats one ill be doing again and i got the genuine part from kwakies n i know i fitted it properly they are just too small simple as that. Good shout with th fuel filter tho as its not been done as far as i know 👍

I agree.thats awesome for someone to follow :clap: :clap:
Lol my valve adjustment pics were just for effect,you couldnt use them for reference but ill put a few more on as i go just in case some of you guys av never seen under the plastic or your engines in pieces 👍😃 :banana: Its sometimes interesting for non mechanics to see the working parts of their bikes.

Well i did my maths or math as jim would say lol and turns out i can swap three shims around so only need four shims. £36 later and a cheap valve check i think. Turns out it had three on their low limit and four out of spec so glad i did it and wouldnt you know my newly installed cam position sensor o ring was leakin again. I knew they were too thin so ive laced it with high temp sealer this time. New shims should arrive tday so ill av her running up today hopefully 👍👍👍😬 :banana:
Yay :banana: :banana: valve check done n finished sounds nice runnin smooth rattled on start up then settled n now silky smooth adjusted throttle linkage n took up play now revs out v nice. Macs a happy chappy :punk:
You're a better man than I, Mac. That job would take me a month and I'd lose half the parts.
yep, very well done Mac :clap:

Ha ha jim youd be able to do it. Its just applying yourself and not being scared thats all.
Thanks oc. It was a saga but only because of waiting for micrometer n shims n bits from ebay. Once i had em it was full steam. V happy. Pulls like a train and runs nice n smooth 👍👍
