i have a 47.5 pilot and 155 main, stock jets for my 88 i was told but running lean. any suggestions. already took the carb out did a big clean to it. Washed the diaphrams and cut the tev spring. all in hopes i could get my throttle response quicker for my test. also moved the white spacer down a notch (my slide needle has three settings) and still no better response. what you think?

Reply #16 - 07/12/12 at 15:03:54 I have had nothing but grief after cutting that effing spring. The white spacer mod was a good idea, and your jetting should be good as it is, although you might try a 52.5 pilot to see how it works for you.

Also it may have been cleaned too vigorously. And be aware, Dynajet has a different numbering system than Mikuni. You may have a Dynajet and be comparing it to a Mikuni.

Reply #20 - 07/12/12 at 15:17:00 If you have a stock exhaust and clean stock air filter, and a plug read is telling you you are too lean, then yes I would try a 52.5 pilot with a Mikuni 155 main. How many turns out is your mixture screw?

Sorry- should what help with throttle response?
This could get confusing. Undecided

Let's start over. Huh

Let us know:
Stock filter? Stock muffler?
How much of the white spacer did you remove?
What jets do you have? Are they Mikuni jets?
To the nearest 1/4 turn, how many turns is the idle mixture screw turned out?
What does the spark plug look like after at least 1/2 hr run?
What specific performance issues are you having? (start with that.)

Gettin a new pilot jet,
stock air filter and stock muffler (wanting to get a cone filter)
my needle has three slots to move the spacer, i put it on the lowest setting.
pilot 47.5, main 155
about two turns out
Have not checked the spark plug
performance issues are that i dont have great throttle response been trying to get it to 25 km/h but it bogs out about at 15 kilometers. mainly trying to get better throttle response

Reply #24 - 07/13/12 at 04:50:30 Bogs out at 25kph That sounds more like a serious carb problem, rather than just jetting. Possibly a damaged slider diaphragm. If you aren't comfortable investigating, I suggest you take it to a trusted bike mechanic to have it looked at.

Reply #25 - 07/13/12 at 06:06:42 Bogs out.. please be more specific.. engine power decreses or fails to increase? does it slowly pick up from there or is that as fast as it runs? What happens if you pull the choke a click? Have you had the slide out? Were you super duper extra persnickety about it goin back in without so much as a fingerprint on it?
