Does anyone remember a similar issue during break-in?.. Or do i really need to check my valves...?

If u have trouble starting in warm situations why are u wanting a smaller pilot ??? My carb is set up with 20 pilot and 245 main and is not optimal without my big bore. I went to stock carb jetted 25 and 135 with a 250 s needle</end quote></div>



The 20 pilot/ 245 main on big bore was that on the TM28? Trying to get a good starting point on my big bore. What elevation r u?Thanks</end quote></div>

500ft. Also specified that on the jetting when sudco did it

This was posted a while back. Just don't baby it and you'll be ok.... Get the revs up and ride it hard before day#1 is over.

Guy at the suzuki shop told my buddy his 1990 250s was a 1970 model.[img]i/expressions/face-icon-small-confused.gif[/img]

Question was for qs270, he had the same big bore....
I appreciate all your info as well, but his old set up is closer to mine.

My goal is to have a rich situation for break in, THEN i will go for perfection on the jetting.

Because I have a hard time starting when warm. Think about it. If you use a choke when its cold outside, then you need to do the opposite when its hot. So, I need a smaller pilot.</end quote></div>

if u use the choke does it start easier? my elevation is round 1000 ft.
