Hi, great post on the install. I have just completed this myself and the only problem I have encountered is an increase in tappet noise. I have checked and re adjusted the valve clearance several times to the specs supplied of 004" and 006" and then even tried reducing the clearance to the original settings, but it just slightly reduced the noise of quite a noticable loud ticking coming from the valve gear. I was wondering if you had this problem or you could suggest a area to look at? Any information would be greatly appreciated.
Kind regards. Cameron
i have the same problem...still trying to track down the ticking noise...bike runs fine, gaps are correct.. I am going to pull the motor down after i return from speed week at lake gairdner. noise sounds like tappet noise but i am unsure...but runs ok...quiet when cold but ticks when hot
being a pushrod motor without roller rockers etc , its always going to make some tappet noise, and as it gets hot it gets louder, its normal to hear it
I am not concerned that the motor will eat itself, just noisier than with original pot and piston. strange seeing how it is all the same rocker gear pushrods and cam...might be the steel in the new valves expand at a different rate?..
anyway don't panic about the ticking. i am not...just puzzled to why it is louder...my valve stem clearance has been set back to standard, not recommended gap by oo racing. i have refitted base gasket to cylinder not left it out as recomended as well.
motor runs fine . top speed of 115 kph with 17/38 gearing(maybe more but didn't push my luck).
Hi again. I have been re reading through your guide to the install of the kit, and I think I may have picked up a problem when I put it back together that is causing my louder than usual valve gear noise. When I looked at your photos of removing cam followers and being carefull not to loose thrust washer it got me thinking that when I put the followers back through the locating pin I put the thrust washer between the two followers!!! Is this incorrect? Should it be placed at the end of the pin towards the centre of the motor?
Thanks again in advance for your input. As a recent sign on to this site I have been blown away with all the great info and passion for these bikes. Keep up the great work, it makes great reading and is inspirational.

That's how its shown on the Skyteam drawing motor - on the end that is

Great news that the fault is mine and not the bike!!! Thanks for the photo, it was just what I was thinking about.
Pretty dumb mistake on my part.....I will let you know how I go when I do it tomorrow. Might have to make a new gasket for the bottom of the cylinder or is it safe to do it the way suggested with a smear of silicon sealer and no gasket? I have high quality 220 c silicon sealer is this ok?
Update..... this afternoon I removed the head and cylinder to rectify the incorrectly placed thrust washer. When I turned the cylinder over to drift the locating pin out I couldn't see the washer. All sorts of thoughts ran through my mind like did it fall out of my hands when i was putting it back together? Did I put it in then take it off because I wasn't sure where it should go, then leave it out all together by mistake? It all became clear when I drained and strained the oil...... Feeling a bit sick at the moment with the thought of my extreme incompetence.
Where to from here? Does everthing need to come apart now?
Removed motor yesterday and all bolts around the centre of the crankcase, but when trying to seperate the two halves I could easily get around a 3-4mm gap but that is about it without forcing anything. (Also removed the clutch side cover and inspected for any of the broken washer, but nothing in that side.)
Is there something else that needs to be removed before the two halves can be seperated for inspection purposes?
