So having gotten plates for both my PA50-II and my Magnum II
last week, I was eager to have at least one of my peds running
this Saturday. My Proma pipe did not arrive in time to set up my
DR kit so I switched out to stock before peicing everything back
together. I also did not have the proper jet sizes or performance
reeds to run the DR kit.
The Honda started after only a few tries. It would only run with
the choke on. It would sputter out if I tried to push it past 10 mph.
I'm pretty sure the Keihin carb just needs another thorough
cleaning. I'm definitely running into an air flow / fuel flow issue
inside the carb. I hear these things are pretty fussy when not
properly cleaned. After all, this bike has only 230 miles on it and
hasn't run in over 20 years. In my next attempt, i'll also try running
it without the air filter, though mine is brand new, as a test.
By this coming weekend I should have my 78-92 jets, my
Boyesen performance reeds, and my Proma pipe. I will get
the moped to run solid as stock first before attempting to run
the DR kit and new pipe.
I did have the Boyesen dual stage reeds for an unmodded
cylinder installed on this run. I was impressed with the low end
torque and attribute it to this reed upgrade. I may throw the stock
reeds back in just to compare.
toiling with the same issue on my stock hobbit. those carbs are a fickle bitch.
ReplyDeleteYep.. Gotta clean those boogers out completely including all the worm holes emulsion tube behind the jet, your fuel lines even the tank. your best bet will be to get another pepcaulk and whatever you do make sure you use OEM drive belts i've torn up my variator using not the right belts.
ReplyDeleteone of the things that really suck about these hobbits is you have to drop the engine in order to get at the carb. that is true about my 78 i am not sure about some of the early 80's models.
