Exup 1000

A compression test would help... Do one to rule out a a goosed piston... I've seen holes blown in piston tops.. Have you done a physical check on your headers whilst the bike is running.. Touch them,,, carefully to see if it's hot on no3.. If it is hot, strip your carbs, check and clean everything a...

i had an ancient mercury sync tool ,which i tried to use but it was jumping around too much to use. so i got by with a uni-syn tool and moving it between the carbs. but i will make some better brass nozzles and plugs and get heavy duty rubber and leave in situ. thanks for the link to the FB page. m...

Hi all.... As the title states, has anybody had experience with this set up.. Mine has been done by previous owner, to stage 3..

Cheers stig....im drooling over that.. :retard: Your needles are what i have in one set of carbs..5 settings. My other carbs have fatter needles, 6 settings, 143 main jets, and a capped main air jet....definitely been took to a stage 3 mod.. To answer my original post, YES standard needles can be lo...

So i presume standard needles work in the same way,, up 1 setting to lower needle making a leaner fuel ratio...so why the need to change needles when fitting a jet kit..????

So standard needles are adjustable.. Thanks for that...at least one set of carbs are STANDARD... And looking at at them side by side, ones definitely been tarted...thanks guys..

Are box standard needles height adjustable??.. I own 2 exups,, both 1992 models.. One has definitely been jetted/fat adjustable needles (6settings)/main air jet capped off etc.. The other is running standard jets, adjustable need(5 settings) standard air box, main air jets open etc.... What is the n...

Hi all...just been through my plugs to cure a missfire, hoping i didnt have to replace my caps...I found on the cap in question had come loose internally over the years..I was unaware that the internals unscrew and can collect moisture, as mine had.

Hi all..jyst done a carb stripdown, and found its been jetted by previous owner(s)......originally stripped it down to clean and synch carbs to cure a carb pop on number 4 (sitting on bike, last pot on right) and slight bogging in 2nd at low revs to open throttle. Carbs were grainy inside, and found...
