Uf21 Posted August 4, 2013 Report Share Posted August 4, 2013 So I did a plug chop while at my riding spot on sunday. How do they look? There's also a weird marking on both plugs on one side. First plug: SECOND PLUG: Quote Link to comment Share on other sites More sharing options...

pickerg1 Posted August 6, 2013 Report Share Posted August 6, 2013 (edited) Lean IMO. I'd fatten her up and see how she responds. Edited August 6, 2013 by pickerg1 Quote Link to comment Share on other sites More sharing options...

Uf21 Posted August 6, 2013 Author Report Share Posted August 6, 2013 What should I go up on? Mains? Also those marks on both plugs, what do they mean? Quote Link to comment Share on other sites More sharing options...
special06shee Posted August 6, 2013 Report Share Posted August 6, 2013 When performing a plug chop you are only tuning the mains. Bump up 2-3 jet sizes. Quote Link to comment Share on other sites More sharing options...
Uf21 Posted August 7, 2013 Author Report Share Posted August 7, 2013 ok, is that very lean or border line. I'll go up 2 sizes. Also does anyone know what those weird marks are? Quote Link to comment Share on other sites More sharing options...

jayhawkatv Posted September 5, 2013 Report Share Posted September 5, 2013 27.5 pilots are a good place to start also Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted September 5, 2013 Report Share Posted September 5, 2013 (edited) What should I go up on? Mains? Of course. A plug chop is Main jet. Id go 3 sizes more(then try the chop again). I did mine as recommended then when it was good, i went up one more richer. Bike ran perfect for over 3 years.
