tdod101 Posted August 24, 2015 Report Posted August 24, 2015 (edited) Left side seems to be a tad wet and black, right side is tan and dry. What can I do? Brand new motor, 4 mil redline dune port, 28mm carbs. I'd say I'm pretty close. Edited August 24, 2015 by tdod101 Quote
sheerider11 Posted August 24, 2015 Report Posted August 24, 2015 That first pic they look way off Quote
tdod101 Posted August 24, 2015 Author Report Posted August 24, 2015 Rich ? Lean ? I'm not very good at diagnosing plugs Quote
tdod101 Posted August 24, 2015 Author Report Posted August 24, 2015 (edited) New, very first ride on a new motor Edited August 24, 2015 by tdod101 Quote
sleeper06 Posted August 24, 2015 Report Posted August 24, 2015 Did u assemble motor or cam did it Quote
Deadbeat Posted August 25, 2015 Report Posted August 25, 2015 whats the history on the carbs are the boots in good condition, plugs should look same somethings fucky Quote
tdod101 Posted August 25, 2015 Author Report Posted August 25, 2015 (edited) Boots are brand new, everything including hardware to seals is new on this motor, I spared no expense. New new new! Might as well have come straight from the factory that's how new everything is, minus the upgrades obviously. Carbs are 28mm mikuni, I dipped em in carb cleaner for 24 hrs, rinsed in hot boiling water and blown with compressed air. As I always do. Edited August 25, 2015 by tdod101 Quote
sheerider11 Posted August 25, 2015 Report Posted August 25, 2015 Something is off. You can clearly see the difference in the plugs. Do a few plug chops and send the pics to cam. He should be able to figure it out. Quote
tdod101 Posted August 26, 2015 Author Report Posted August 26, 2015 (edited) I may have figured it out, re routed the fuel line, I think the one carb wasn't getting enough gas and had air in the line, shortened it up and flows freely now. I'll do another plug chop or two as well. I got pump gas domes but with Cams kick ass motors I think I'll have to use 93 octane instead of 91. Perhaps go up a main jet size as well Edited August 26, 2015 by tdod101 Quote
mike0chek Posted August 26, 2015 Report Posted August 26, 2015 have you done a leakdown test? theres def a huge difference in colors Quote
tdod101 Posted August 28, 2015 Author Report Posted August 28, 2015 Still no luck. I did notice a small hole in my Toomey T5 though, could that be it? Quote
nastyracing Posted August 28, 2015 Report Posted August 28, 2015 Check your float height on your carbs 28s are hard to get bowls on with out finesse and you should never force them on it knocks the float height out on them . Just my opinion when I began tuning it was with 28s and plugs looked like that till I got the nack of smoothly taking apart and putting back together. Is one pipe hotter to the touch then the other?
