can any one please tell me if a stage 3 dyno kit is fitted, is it only the main jet,s that are changed in the carb? as i have a 4 in 2 one exhust fitted i have taken the pod filters off ( it was poping back through the filters ) the carb, and put a standard air box on, but at the moe it has 125 main jet,s fitted, ( when cold it is a bitch to run when warm it goes like stink you open the twist grip at 70 in top and it fly,s to 3 figers )would you think going to 115 would be best, at the moe under 2200/2500 rev,s when moving off it seem slugish,
thanks outlaw

Best to get it set up by an experienced person with a dyno.

hello mate, have you checked if the carb's have had an air correctors fitted in the pilot air way at the rear of the carb. you will need to remove this if you put the air box back on or it will restrict the air flow at low rev's

Hi John,

As bgb says, check for air correctors first (will be like little jets, screwed into the pilot airways).
If none fitted, you will need to open out the air screws.
Pick one of the air screws and turn it in until it (gently) seats, making sure you count how many turns ( you need to know where your starting from ) Turn screw back out to where it was and add half a turn more (out).
Then turn the the other air screws all the way in and adjust out to match the first one.
See if that improves the tickover, if it needs more increase by 1/4 turn at a time only.

Hope this helps.

From memory the needles are also replaced with a #3 dynojet kit.

Going by the jet size's you mention, I wonder if they are dynojet at all (if that's what you originally meant)
Bshaw's memory is sound! It is main jets & needles.
I have dug out my dynojet parts list for you, hope this helps!
