Thoughts on valve regression

Postby Stuart SS » Sat Nov 28, 2009 1:41 am

Pezza asked on his (re-) intro about issues he is shaving with Valve regression.

IMO ~ this is the first time I have heard of ~ Must have some crap fuel in the west eh Perry ~

When I went through the regression issue some years back with the Commando ~ I ended up using Nulon Octane booster.
I actually rang the 1800 number and one of their tech heads rang me back and had a chat . He was of the opinion that ( I think It was the standard recommendation ~ 40 mills per litre ~ although that sounds excessive to me ~ can't find the bottle just off hand ) But the mix is listed on the bottle ~

He felt that this would give an adequate valve protection to pre-unleaded engine ~ (plus the benefit of octane boosting.. )

well stu i recently started using Valve saver and have to put 5 mls to 50 litres my tank the small one for the time being is i think around 8 litres so i put about 5 mls in a tank of unleaded. I was told the bloke who rebuilt the bike to use BP ultimate and another Triumph dealer told me it was crap and use unleaded and a bar, I'm not sure Wat it is called but i think it converts or puts lead back in the fuel and will last 250.000 K's ( according to him anyway. ) I am however not sure how long it will take b4 i start to feel any difference. I have only used the stuff 3 times so far so will have a look, i may have to reset the valves first to see it it helps. Stu did it actuall make your norton run any better? the main issue i'm having is ideling at stop lights!!!

Hi Pezza

I suggested mushroom headed tappet adjusters elsewhere ... but have I assumed wrong and the problem you've got is valve clearances tightening up rather than increasing?

Impressive list of users. Pricey little things ...aren't they just lumps of solder?
