YAMAHA XT660Z FUEL MOD

[SPEN]

I have twin MTC"s ,fuel mod and snorkel removed with the DNA filter ,bike pulls harder down low and just keeps on reving ,you could hit the limiter in every gear .

You need to blank off the air bleed pipe to help stop the popping. It doesn't stop it completely but is a lot better .

Thanks for that redbikejohn, I will try it.

Remove right hand side airbox cover and there is a pipe right near the top front that needs blocking. M 10 cap screw fits in nicely with a bit of sealant.

Thanks again John. Just ordered a 3K ohm potentiometer off ebay.

And if you need a DNA filter let me know i have one of my 660

Hi i thought it was 1k ohm :huh: i read on xt660com.?And blue and black wire jump into.

[redbikejohn]

1k is for the x and r models. The z needs a 3k Aaron its a different system

Can you confirm that the splodge shown in the photo is the pipe to be blocked?

[redbikejohn]

That is the one I did. Still pops now and again though.
