Hi, i received the Yamaha speed jet kit, it came with 4 main
jets, 160 165 170 & 175. The main needle with clip adjustment and 2 stainless washers plus one bigger plastic one. Also the two pilots that came are 50 & 60.
I have a open exhaust with baffles incorporated (due to a bend at the end is not possible to take them out or add anything). They are not hugger.
Also i use a new K&N filter that goes inside the stock air filter unit.
Right now my setup is
Normal height is 1050 meters above see level.
Is not running bad; but when is running without throttle applied, as soon as i hit the gas, it looses power for a mil-sec and start pulling fine. i have pulled 100 mph at level fine.
What i feel is that is not working good in the middle throttle, the spark plugs are clean, no black showing in both front and rear. Here regular gas is red, so they show a reddish color. Before i took the carb
out they were black and the spark tip barely clean. Seem to be much better now, i think is lean due to the cough when i pull the gas and is at idle.
I would like to use the main needle, but don't know what could be the right clip position due to my setup. Can i use the 170 main jet too?
What about the pilots is 50 too big for my setup?
I know, the bike is not that bad right now, but I want to use the new kit. Also received some parts for rebuilding the carb due to needle don't stops gas form flowing, so if i don't turn the tank valve off, the back cylinder will fill with gas and have a hard time starting.
When i start the bike it needs chuck for more than 2 minutes to stand idle.
Bike has improved a little about mileage but is doing 32 to 33 in heavy traffic. (normal here)
This weekend i will go for a 200 km ride (to the beach side
and need to have the bike ready. It will help me to figure out the best mileage with my new setup.
Thanks for the advises!!!
