Basically the plug on the right cylinder is coming out wet still and they appear really white (not sure if the photos show this that well)

 

Its also gutless, a stock shee with pipes is keeping up when I'm doing runs to check plugs

 

I only have enough space to do this in 4th

 

From all the reading I've done 170 mains seems big?

And I have limited carb experience so not sure what would cause wet plug

 

Any help will be great

Thanks

Stripped both carbs, cleaned and inspected everything this is what I found

Like a sticky gunk on the needle, cleaned it off and that solved the wet plug issue

 

Although it runs a lot nicer its still way down on power would this be from the jetting? 48/170 is the biggest I have currently
