The curse of Mikuni 35mm...

[Stein]

Hello you all!

After riding with a DellOrto 30mm without beeing able to tune it in correctly, I have switched to a Mikuni 35mm on my Malossi 210 engine. But, with problems it seems... The setup is 305 main jet, 20 pilot jet, standard needle with clip on second lowest. The engine ran very smooth and had good power, but the engine seemed to get quite hot. Actually too hot, since the nicasil left the inside of the cylinder and made it rather useless...

Today I have switched to another cylinder, a 340 main jet and put the clip on the needle on the second highest. It is now going too rich, but hopefully it wont seize. I should also inform you that I ride with the round Mikuni fuel pump and NGK 8 spark plug.

So, since I am leaving Norway for Holiday in Holland in a few days, and are a bit nervous that it will break down, I would very much appreciale any tip on why the engine gets so hot, and if anyone else have experienced anything like this. BTW, I have checked that the fuel pump is working properly.

I know others that have used 17,5 pilot, 290 main jet and clip on needle at second lowest on quite similiar engines to mine, and managed to keep it from seizing...

And naturally, I am looking for a place with a dyno and CO meassurer that can have a look at my scoot on my way to Holland. Does anyone know about something like this around Hamburg?

Any comments most appreciated!

There is www.scooterandservice.de in hamburg. But at the moment they don´t make any appointments for adjusting. New appointments from the 29.07 and then for august. I wanted them to adjust mine too. Good luck.
