Rich or Lean Mixture? By bonbhead (Read 787 times)

[bonbhead]

I have replaced my stock air filter with this one along with the rejetting.

   

Works out well too after seeing a setup.

Now back to the

re-jet questions

Started out with the

stock jet size of 102

Moved up to a

110 jet

and changed the

air mixture a tad

and it ran Wonderful but gained nothing on a hill.

Now I currently have moved to a

115 jet

but now I do have a issue.

I have  pulled the plug to take a look at it which I will include a image



And I never had the black carbon build up as i see here  yet when I get to 3/4 throttle it will start to BoGG down.

Now for the advice I am asking on this for I was warned a

on the 115 jet may be way too much

Could a possible problem here be with the

Air Mixture

? My main goal is to get a little bit more speed on some of these hills I have here. 35 to 40 max. I can get around 52 mph on a straight stretch but but that is really pushing it on the "rpms"

If I have to I can go back to the

110

jet but I do like the way it does take off from a stop with the

115

installed.

So this is me

and I am too

rich

so I think I need to lean out a little. Which way on the air/mix screw should I go please?

My next step will be on considering on changing the Exhaust System from a Stock to a Performance Exhaust to relieve some of the Back Pressure but I imagine it will be alot louder. I just wish my

Boneheaded asz

would have went for the 250cc when I picked this up in 2012

You are rich,,,and exhaust change may very well bring It in line or split the difference in the Jets 112,,,
