Hi folks. Progress with my lc is as follows. I have managed to sort out my starting issues so starts first kick now with choke. Carbs set as follows. 310 mains 22.5 pilots. Needles not sure. But new of yam bits. Middle setting. Boyesen 2 stage reed new carb to reed boots. Bike was pulling away quite nice but had the mid range splutter quite bad at aroun 4.5 to 5 thou revs. Air screws 1.5 turns. So upped my needle one notch leaner. Mid range splutter moved to about 5.5-6 thou. And cleared better, but made pullaway slightly worse. So put air screws to 1 3/4 turns out made it worse. Went to 1 1/4 turns made it better. Tried needles on leanest notch which pretty much made it un ridable. Tried air screws in/out not much better either way but best was richer. So went back to second notch down and settled for this for now. What should I try next to smooth out my mid range splutter. Pipes are lomas racing expansion chambers. Using pod filters not sure of state of tune of engine but it’s possibly ss stage 3. Also new carb bodies now. Cheers Gareth.
I’ve had all the usual symptoms everyone gets poor starting , poor pull away , mid range stutter at 4.5 -5thou revs I’ve tried everything . Finally bought my own ultrasonic cleaner and used white spirit at 50 defrees heat , put carb bodies in right way up and also upside down an hour each way and all jets too . Rebuilt them with 220 mains and 22.5 pilots . Floats set at 21mm and also clear tube so spot on .all good at 1 1/2 turns on air screw pulls away sweet as but stutter still there . Next step was to fit banshee coils made my own loom properly , still another improvement starts much better ,picks up much crisper off the throttle but still that bloody mid range stutter . Next step I fitted CHAO stage 1 carbon reeds improved the stutter a little Next and final step fitted 6mm reed block spacers on barrel side of reed block and bingo ! Stutter completely GONE ! I hope this long winded list helps you guys , I’m a happy bunny now yeeehah !! Anyone wanna chat about what I’ve done just pm me ok cheers
nah, that carb is done, the locating pin hole has gone which keeps the needle jet in the correct position, scrap I am afraid
Cannot remove my main jet as my needle jet just spins which means, i suppose, that the pin is no longer holding it in position. Pin still sits neatly in its hole when viewed from the outside. Drill it out and replace with something seems to be the answer, but has anyone done so and can help with a bit of advice?
