troyminator Posted January 23, 2005 Report Posted January 23, 2005 Hey guys, I have a 96 blaster as a spare bike and the top end finally went out this weekend. I pulled the head off today and noticed that the piston was seized and had been "shaving" off material off of the piston on the exhaust port of the cylinder. I was going to take the cylinder to be bored out to the next size, so here are my questions: - I couldn't physically see any metal debris in the crank...but you can't really see too much anyhow, so do I need to split the cases and clean everything out or will it be fine...The cylinder definitely had metal shavings in it...and it looked as if the exhaust ports had extra metal where it "shaved" material off of the top of the piston - Also, is there any way to flush stuff out of the crank area without splitting the cases? - If I decided to get the cylinder port/polished, would there be other stuff required to get the bike to run right...it has a bill's pipe on it (diff carb?, etc) - Will I be safe to just rebuild the top end with a new piston/boring out to the next piston size? I know that it isn't a banshee, but it is a Yamaha, so I figured allot of you guys may have these bikes for your wife/kids...so your help will be greatly appreciated! Thanks again, T Quote
98bonerSTOCKshee Posted January 24, 2005 Report Posted January 24, 2005 when I did my banshee top end dirt and crap fell down...My first thought was how in the hell was I gonna hold this thing upside down... I took my shop vac and duct taped about 2 foot of 1/4" fuel line into the end of the shop vac... This aloud me to suck all the crap out easy... Quote
troyminator Posted January 25, 2005 Author Report Posted January 25, 2005 That's a great idea! Thanks, T Quote
NugShee Posted January 25, 2005 Report Posted January 25, 2005 you could also use a magnet like those ones on the end of a screw driver or something to reach down in there and get out any metal shavings. Quote
Leadfoot350 Posted January 25, 2005 Report Posted January 25, 2005 Take it to your local self-car wash and use their pressure washer. Tip the bike over and blast the hell out of it. Dry it with a hair dryer after spaying wd40 so it wont rust. Put the top end back on and do a warm up and change the tranny oil. Also at the dunes after a good ride it would not be a bad idea to change the oil again. This process works very good. You have to clean it out no question about it. Quote
