Hi can any one help, I have fitted a 26mm Dellorto to my TY 250 twinshock but it will not rev out at the top end, It has a 120 main jet and a 44 pilot. does any one know what the correct jets are for this to work?

What condition is the plug in after a top end run and did this condition exist before the carb swap?

44 is a huge size pilot. Also which carb are you using and what elevation/location.

The plug was a little wet but not much. The carb is a PHBL26B

Hi guys sorry no I didn't have the problem before and I am based just out side of London in the UK so not high up.

Thanks for your help

I would try a 35 or 36 pilot and go from there. Check out this post.
