Hi, i own a 1994 TE 610 with Dellorto Carb. I recently rebuild the engine (New Conrod, Main Bearings, Timing chain and ne Piston Rings). I never had the bike running before- i just cleaned the carb and the engine did start within 10 attemps... After that i had some serious problems starting the engine when hot. I replaced the sparkplug NGK C8E with a C7E and the Main jet to a 170- since the my bike starts first, sometimes 2. kick! Mainjet 170 Pilot jet 62 Star jet 60 Needle position 2
i would better save the money- i dont see a reason why invest money if the bike starts straight away and runs fine with the stock setting. Save the money for basic maintainence
