thanks for your advice!i will look out for a good replacement!the bike usually rests on the side stand so maybe thats an issue too since the left bowl will be easier to overflow then.

i will need a 2 way petcock,i have a shop in vienna who sells all kidn of stuff,icluding petcocks in different dimensions.

as for the gas i'm using the standard 95 octane unleaded gasoline we have in austria (we also have 98 octane but i heard to use this is just a waste of money.

Possibly the high Octane rating IS of value.  Just FYI, octane is not a material, it is a theoretical rating based on the percentage of iso-octane that produces comparable results to the sample fuel in a laboratory test engine.  For our purposes, it is meaningful for how resistant the fuel is to enabling detonation (spark knock).  Two strokes are rather prone to this problem.  Past that, it is absolutely true that high octane fuel does not create more power on its own, so if your engine does not need it, it is in fact a complete waste of money.  Conversely, if it does need it because of its higher state of tune, it really does need it if only for self preservation.  93 is generally as high as is commonly available where I live, and my Rd's are definitely afflicted by the low rating.

Sounds like your petcock is leaking.  My Rd's always drip fuel if the tap is on, but not a drop if turned off.  I commonly run the bowls dry - and it does take a while - but you don't have to empty the bowls, just turn off the gas a hundred meters or so before you come in and park.  If the petcock does not leak, you will not have drips - even on the side stand.  I keep one of my bikes inside my house, and there is not even a whiff of fuel odor.  Pingel makes an excellent tap for your tank though it is very expensive.  Their off the shelf for your bike application has fuel outlets that are too large and makes fuel lines tricky to match your carbs, but they will make you one with the correct size for a small extra charge.  Like I said, expensive, but it is a very high quality part and worth it in that regard.

If it were race fuel this would be no problem for me... U-4 with a hint of ester could be a perfume IMO or a nice V-P T-2 after shave  :o

Hydro clutch would be great for racing, but you could get a nice lever and perch with quick adjuster like the one in the picture and along with a fresh cable, you could have almost the same pull feel without loosing that "feeling" of the shutters and obvious end of life warning sign  :o

You know when a clutch gets down to the EOL and slips a little, builds up some glaze and then the lever get the jitters... With that perch and lever setup you can quick adjust for hot and cold running so you are in the meat all the time like a hydro :o

About as useful as t*ts on a hedgehog. Just route your cable properly and/or fit a new one. Furthermore, lube up the clutch lever and bush it out at the pivot, if it is worn. You'll be amazed...

Cheers,

you get no feel on a hydro clutch...new cables and levers do wonders
