Abarth Posted September 28, 2016 Share Posted September 28, 2016 After riding the Honda home the right cylinder started smoking like crazy in traffic, bellowing a white smoke screen behind, which is great from high speed escapes but not so much oil consumption. I assume what's happening is that once the oil heats up it runs past seal and into the combustion chamber. Question is - is there an easy way to change them without having to take the head off? It looks like a generic collet that holds the valve spring. Need a valve spring compressor that bolts to the head? Quote Link to comment Share on other sites More sharing options...
MaxPower Posted September 28, 2016 Share Posted September 28, 2016 can you run compressed air through the spark plug hole to hold the valve in place while you replace the seal? have herd of people using thin rope through the plug hole at the bottom of the stroke then winding the piston up but i don't like that idea.

Raizer Posted September 28, 2016 Share Posted September 28, 2016 Rope works damn well, and for me at least feels much safer than using air. Quote Link to comment Share on other sites More sharing options...
Guypie Posted September 28, 2016 Share Posted September 28, 2016 I have done the rope trick on a mini before cause I was super clever and forgot to put the seals on when assembling the head. It worked mint, and I learnt a lesson on checking my work. 1 Quote Link to comment Share on other sites More sharing options...
SOHC Posted September 28, 2016 Share Posted September 28, 2016 A few of my bikes run no valve seals and they only do a puff of smoke on start up, you might find its piston and rings witch need attention if the bike is smoking alot all the time. 1 Quote Link to comment Share on other sites More sharing options...
fuel Posted September 28, 2016 Share Posted September 28, 2016 I'm about to go through this myself - but yeah I think you should do a compression test first both cold/hot and dry/wet to get an idea of the numbers (do the other side so you know what to compare it with). Â I bought a cheap head on valve spring compressor tool from fleabay and will get around to it eventually using the rope trick. Quote Link to comment Share on other sites More sharing options...
Roman Posted September 29, 2016 Share Posted September 29, 2016 I remember reading a thread on another forum, where a guy fed the rope in and it knotted itself while in the chamber... So stuck with rope in his motor hahaha 3 Quote Link to comment Share on other sites More sharing options...
fuel Posted September 29, 2016 Share Posted September 29, 2016 yeah that would suck! I guess buy rope that has that slippery coating maybe? Quote Link to comment Share on other sites More sharing options...
jakesae101 Posted September 29, 2016 Share Posted September 29, 2016 id say that would only happen if you used really small rope id say you would want the biggest diameter that can fit in the spark plug hole and still get it to feed in 1 Quote Link to comment Share on other sites More sharing options...

Guypie Posted September 29, 2016 Share Posted September 29, 2016 Yeah I used the plasticy yellow rope that doesnt tie a good knot. 1 Quote Link to comment Share on other sites More sharing options...
