Top-end knock

[aviscomi]

I have a knock/rattle in the top end of my Blaster; it still starts on the 1st or 2nd kick and it doesn't seem to have loss any power. Rings? Piston? or both? The top end only has about 30 hours (Vito's Big Bore).

mabye detonation...but blaster's always have this hitting noise to them...ever blaster I"ve ever heard made a knocking noise its just the timing I think...nothing to worry about....

But check ur plug just incase and make sure everything is normal

[SickCRrider125]

run some higher octane and see if that takes the noise away, blasters tend to do that for some reason though

[aviscomi]

I already run 93 octane w/an additive and I have a Nology coil. It just started doing this recently, I've been running pretty hard on some really HOT days!

[$evy]

yeah lol take it easy on it on hot days lol....don't want to get a new motor after all that spent on it lol...

yea my buddies make fun of me sometimes for "not ridin" my banshee, meanin ridin like a bitch, oir going easy on it, but fuck it, on hot hot days likes it been latley here in NJ 90-95 and humid for the past 10 days or so, why risk overheating and fuckin uyour quad up? its not worth it, they can blow up their yfz450's and banshee if they want but i never abuse my shit, if we are all racing ill do one race, run it to 6th gear, flat out, then back off and go back down through the gears nice and slow and then makea few runs throught he open feild just babying it, lettin her cool off, i feel bad for her doin all that work on such hot days, some of my dumb ass friends will just keep linin up and racin and fuckin revvin it out on evcery gear, then linin up and doin it gain and again then rippin up hills then line up and race again and flyin 6th gear flat out then race again they are morons,smokin evyeyrwhere liek assholes, then they willl drive up to me and just shut it off, still smoking, hot as a bastard, theyll race to 70mph then just drive up and park it and shut if off, i duno what some peopel think, last time i checked the only time a radiator did u any good was when air was flowing through it..... i baby my shit for a reason, i want her to stay with me not leave me i love her

[Flattrack]

Hot days mean higher temps witch might be causing a little detonation problem of course 30 hours on a big bore is quite a few....I would at least check your plug for signs of detonation....

If you want it to stay cool then go fast. When I put around with my banshee is when it is the hottest because there's no air passing through the radiator. If I'm screaming in 6th I can watch temp guage creep down.

[erik6767]

how and where did u install a temp guage on the banshee PA_Banshee?? that sounds like a really good idea

Here's are some crappy pics of where it's at, I need to get some more pics of it clean. I got it off of this site. It's pretty easy to read while you're riding and not easily damaged cuz of where it is. It's essentially a meat thermometer in a plastic tube that you insert into your radiator hose.



This one's out of focus but you can see where you look at it.
