Hey guys. I have a 2001 blaster and i just got a trenga racing oil block off kit. Before i got the kit it was running fine but i didn't want to take a risk seizing up my engine. after i put the kit on it first fouled a spark plug rite away and then i put a new one in it and it ran fine all day. after letting it sit after i rode it it took me 15-30 kicks to get it started again. Im just tryin to figure out wuts wrong be it the jetting or anything. Any advice on fixing it will greatly appreciated. thank you.
