Hi All,
New joiner, after picking up my first Guzzi, a v50ii, last summer.
I have used the search function to try and identify similar issues, but not found any. Sorry if this has been asked before.
I serviced the bike myself a couple of months ago, and in doing so I have replaced the air filter with the cone filters from Gutsibits. I took it for a run after, it’s power was fine, pulling through all the range and no flat spots. The only problem was constant backfires every time i shut off the throttle, as such I changed the main jets to the 115 recommended on Gutsibits for the cone filter change.
I took it for a run again the other day, and whilst the backfires had stopped, I experienced two problems:
- on two occasions, when pulling away from a stop there was a half second of complete power loss when opening the throttle, not so much a ‘delay’ in the delivery, the bike started to move for a second, lost power for half a second (juddered) then kicked back in.
- when hitting 70mph if i continued to try and accelerate the revs went up (and quickly) but no further speed increase.
Does anybody know if anything else needs changing or tweaking within the carbs to alter the air to petrol ratio?
Cheers,
James
