Richi gets a gold star for the cocktail stick suggestion! I'll see how it behaves when I get the carbs back later this week, I know it will need tuning properly after that to be at its best but its like Chris says - it would be nice if we could find somewhere that is less than a 4 hour round trip. I've been out 3 times in my car now, for less than an hour at a time - and its broke down 3 times! At the moment I would prefer to stay close to home till the gremlins are banished...

The mid range is the critical one, but as you say, if your guy knows his stuff he will know to richen it in the mid range... Top end then becomes important as you will be generating more heat with an efficient mid range...

As long as you check the plugs after a blast and they are tan-sooty then you are safe.. if they are spotlessly clean and look a bit shiny, beware...

Just to chip in with this one. My R1 was running lean and was consequently missing at the top end (7k+). I had the filter off today and thought what the hell Ill try the cocktail sticks and see what it does.......completely tranformed it. The difference is staggering. It will still benefit from a jet kit but at the moment the thing is flying how it should.

If youre on stock jetting and have the same problem - give it a whirl. Is this hole left unblocked when fitting a Dynojet kit?

Top suggestion, thank you

Rich

Cool - ta. Am I right in thinking the one which dynojet say should be blocked with epoxy is another one down the throats?

Honestly cant believe there was such a difference from those holes.

Cheers

Rich

I thought the one they do is down under the butterflies somewhere. Mine definately hasnt been dynojetted as it had the brass caps over the mixture screws as set in the factory and the needles have only one notch on them. Also, the numbers on the needles are right out of the manual.

Interesting though that just this should make such a vast difference

Not as such but it did come with a US loom and the same with the carbs as they had the brass blanking caps to prevent tampering of the mixture screws for emmissions regs. Rescued attachment plugcloseup.jpg
