Just got it firing!
Hi Guzzistis,
My T3 starts and goes fine in town, but on highway I noticed that it struggles to rev beyond 4800 (in fifth gear). At the point of stuck, it starts of kind of hesitating, it's not like one cylinder would not go, it's rather a strange near-interruption feeling. Interestingly though when I pull the clutch (as soon as the issue starts presenting itself at around 80 mph) to see if it can rev up without being in gear (like in neutral) it revs up fine till 6500 (possible also beyond, but wouldn't like to do that to her).
So in neutral it can rev up nicely to any regimes, but in gears less and less.
So I checked the acceleration in all gears, and in 1st gear it still reaches about 6000, in 2nd 5700, in 3rd 5300, in 4th 5000 and in 5th 4800 (which is around 130 km/h).
On a theoretical level, what would you suspect might be wrong? I would obviously start with checking spark plug, carburetors, and then maybe advance, but given that the issue is not present in neutral, I kind of suspect the coils.
Basically my question is would you be checking electrics or fueling system first in such case?
I know that such old carburetors run rather fat, but since I have the K&N filter (the original shape in the original housing, not the the two separate cones) installed, that should be compensating it, as it allows more air flow. (Carburetors have been thoroughly cleaned 2-3 years ago and I always make sure there is no fuel left in them when the bike stands for longer periods over winter, so we should be able to exclude that something is stuck).
Would be grateful for any pointers. Many thanks in advance.
Best regards,
Tom
