i'll probably put the o2 sensor in for final tuning and then pull it out. everything i read from the 4 stroke guys said that the ngk sensor was way more accurate then the bosch(sometimes as much as 1 number difference) comparing it w/lab referenced equiptment, and lifespan sometimes was fourfold. the snowmobile guys seem to run around 12-13.1 at cruise w/ the 2 strokes

That's great to hear Charlie! Can't wait to hear how it runs once it's all dialed in. Mine is sitting in the driveway covered in frost right now! It's going in to hibernation this week.
that sux dave, i heard it was getting cold up there already, i think its supposed to be 89 here today, it would be nice if it cooled off a lil here
Must be nice! I wish we had to worry about it cooling off right about now!!
:iagree: Dave, 31 this morning......BURRRRRRRRRR.......:pQuote:

that looks interesting, looks like individual runner? i was thinking for the next one of building a common plenum w/ 2 throttle bodies so it spreads the airflow out a lil.
you'd be hard pressed to fit that under the 3 litre cowling, lol!Quote:

by playing with different restrictors look wat the torque curves are doing
i was also looking for a 6 throttle valve setup but prices sky rocket
here is a nice one for alfa romeo but the price is not even listed

better one maybe ?

but it,s hard to decide on a diameter !!
maybe taking the throttle size of the evinrude,s and go slightly larger ?
