baddboyy21 Posted April 21, 2004 Report Posted April 21, 2004 Okay...here is the deal I have two Banshees, One is modded and one is stock. The stock one is getting hard to start. The only mod to it is a K&N Filter Set up with no snorkle and and 6 1inch holes in the air box. The bike is still on the stock bore. It really hasn't been rode hard, the reason being that my girlfriend is the one usually riding it. I have the stock exhaust on it still. I am at 1250-1500 feet above sea level and usually ride at about 60-80 degrees. I bumped up the main jets to 240's and stock 25 pilots for the filter set up. The bike starts hard cold but idles fine. I did a compression test two different ways. The first was done cold, 5 kicks WOT and got about 117psi. The second was cold and I kicked WOT until the guage topped out. Both cylinders topped out at 120psi. Is it time for a rebuild? Could I need bigger pilots with the K&N? My second thought is that maybe the stock silencers are clogged. I had to remove the end caps on both of my quads when they were stock. With the end caps on it didn't seem to run right. I hate to tear the engine down and do a rebuild if I dont have to. I already have .020 over piston kit. I can do it if I have to. Should I replace the stock exhaust and maybe add a Noss head to this bike also? I have been riding a modded bike so long I dont know what a stock one should feel like lol. Quote
MotulMonsta Posted April 21, 2004 Report Posted April 21, 2004 Naw dude, your compression is good, your starting issues lie elsewhere...I'd say it's electrical. Clean up all the contacts on the flywheel and pickup..then clean up all the connections in the wires. Water will condensate on the flywheel and cause hard starting. You say it idles fine and runs good right? How old are the reeds? I had starting issues for a while on my shee..someday's it would fire right up, other it wouldn't..then after I had it running and shut it off it wouldn't start back up..well needless to say it was quite aggrevating and after I replaced my coil twice, rebuild my stator and dropped in a new cdi did my starting woes end..Oh and I got a brand spanking new wiring harness as well.

baddboyy21 Posted April 21, 2004 Author Report Posted April 21, 2004 This bike is like brand new. I just did some more investigation. It appears that the stock silencers have water in them. I started the bike and water was coming out of a rusted pin hole. I think it might be the silencers. Quote
MotulMonsta Posted April 21, 2004 Report Posted April 21, 2004 Pull off the mufflers and see if it starts better. Cheapest way to find out. If it's like brand new, how did the mufflers get all rusted already, mine were 14 years old before they literaly fell off while I was riding. Quote
baddboyy21 Posted April 21, 2004 Author Report Posted April 21, 2004 They werent all rusted...the silencers got water in them from washing the bike! Quote
baddboyy21 Posted April 22, 2004 Author Report Posted April 22, 2004 I put the stock silencers on that I had from my other bike. I am in process of cleaning the carbs. I'll let you know soon as I get it back together. Quote
baddboyy21 Posted April 22, 2004 Author Report Posted April 22, 2004 Okay...problem is solved. I switched the silencers with my spares from the other bike....cleaned the carbs. synched and tuned them. Starts on the first kick. It needs bigger pilots....I have the 25s in there now....the air screw is only .5 turns out for the best idle and throttle response....Im gonna go up to a 27.5. Quote
