Subject: tuning - carburators - airfilter- exhaust
Hello to everyone,
it took me a long time to start working on the engine of my @, but now it was to cold for driving and so I stopped driving for the next 4 - 6 weeks ( depends on the snow during the next weeks).
Last weekend I started to look what my @ has inside of e.g the carburators, airfilter etc., and now I'm a little bit confused because I found some different parts than I have heard I should find.
Please can someone give me information about following details, in my opinion a @ with 60 hp should have other measurements than I found:
- plastic induction pipe (" Ansaugrohr") between carburator and cylinder min diameter ("Durchmesser") about 32mm
- diameter of carburator ( at cylinder side) and cylinder ( metal) about 36 mm
- diameter of carburator ( at air filter side) from about 39 - 35 mm (conical " konisch"), there is an alu inset ("Einsatz") that can be eliminated, should it thrown away (like a "Drossel")?
- marking at the housing of the carburator at the side of induction pipe airfilter : 50 C A GL
does this mean 50 hp configurated ?
- nozzles: front cylinder ( right carburator) main 118, small 38S,
nozzle without notch ("Kerbe") for screwdriver 60, "Schwimmernadelsitz" 2,0
rear cylinder (left carburator) main 120, all other as on the right side
In the past I got informed that there are some methods to slow down the hp of @ from 60 hp to 50 or 34 hp, do I have such a slow version ?
Two months ago I read the infos of Raymond Fels and another guy (don't remember his name) regarding tuning of @ unfortunately I couldn't read the graphics showing how to change the airfilter side for getting more cold air ( not the solution to make two wholes about 40 mm on the left and right side that is what I already knew , there was something else), is there someone who can send me the graphic showing what to change?
Furthermore I have to make some changes at the nozzles because of airfilter modifications (I want to mount a K&N who knows where to get at best price) another exhaust ( Arrow open version) and maybe change of plastic induction pipes if necessary, I'm thinking about to use a dyno jet kit but don't know how those parts look like ( pictures available? where to buy at best price, price expiriences?) or is it also a good solution to use only other nozzles( can I reach the same result of hp and torque?)?
It would be very helpful for me to receive competent information from some of you ( I know that a few profis are reading the mailing list).
kind regards
