you thinkits to rich for break in?.....i have a 102 main jetin right now what do you sugest

I don't think that's a proper mainjet plug chop as your still breaking it in unless your breaking it in at wot or more than 1/2 throttle on a constant on your ride? If your less than 1/2w throttle on your ride, its a pilot jet and needle that's running rich.

What does the temp gauge read when your riding?

your right it is not a proper plug chop.....i havent went over half throttle yet being that i am in the break in process still....the highest the temp has gotten was 286...but at a stop lightt it drops

so do you think i should leaveit untill im done breaking it in or down jet some now?

Your 280deg temp right there is a sign its rich. You can lean the needle 1 clip . I bet it burbles a lot when your just getting on the throttle? What do you have the air/fuel screw set at? Where is the needle clip position right now?

it burbles A LOT...my af screw is only a half turn out and the clip i have no idea it is where it is from factory so imguessing the middle....after break in period what is a good running temp

Yeah that air/fuel screw is in way to far.What size pilot jet in there? You can get the temps in the low 300's for breakin. At wot you want to see around 385

There are no hard numbers for idle mixture screw settings. You adjust for the highest idle speed possible, then adjust the idle speed screw for an idle of 1800 RPM.

Looks like a very cold plug

What temp gauge do you guys suggest? I would like it to be hard wired not just a BBQ type. Thanks

The trailtech tto temp gauge is a cheap good one. Plus its small to put anywhere. You can get one of those for about $45 shipped
