Zacharysalis Posted April 24, 2014 Report Posted April 24, 2014 i just recently bought my banshee off craigslist and on post it said it had a 418cc bore but i have been looking up bore kits and yet to find a kit that does a 418, so my question is is that bore size even possible or is it just a fib? Thanks. Quote
WINDYCITYJOHN400 Posted April 24, 2014 Report Posted April 24, 2014 (edited) Fib It's possible… But it would have to be a 64.5 bore with a 10 mill crank. (Anybody with a motor like that would have PLENTY of details for you) Even a standard 4mill with bigger pistons only hits 403cc. To eclipse those numbers you would have to sleeve it for a 68 bore. I'm betting you got a major scam. Or the guy is doing some convoluted math based off of some overbore numbers he didn't understand. (No "bored 30 over" does not make a motor a 380) Edited April 24, 2014 by WINDYCITYJOHN400 Quote
Zacharysalis Posted April 24, 2014 Author Report Posted April 24, 2014 it is a 4mill so i wonder what it actually is everything else about it is correct so maybe it doesnt even actually have a 4mill in it? but everything else that was written in the add was correct Quote

Starwriter Posted April 25, 2014 Report Posted April 25, 2014 That bike has been for sale for at least a year. Maybe 2. Has a lot of aftermarket parts, but it's sure ugly. Time to strip, repowder coat the frame, and recover the seat. Quote
WINDYCITYJOHN400 Posted April 25, 2014 Report Posted April 25, 2014 What's wrong with it ? Claims it's a size it couldn't be. (Well it's POSSIBLE that it could be sleeved for a 68 bore…….But unlikely) Talks about a it being a big bore, but no mention of any porting. (bore doesn't make power in a 2-stroke. Porting is everything!) Were the carbs really bored? (Time to verify everything) Quote

WINDYCITYJOHN400 Posted April 25, 2014 Report Posted April 25, 2014 Windy you'd understand if you knew the guy that "built" it.......unfortunately , I did. Oh, I don't know the details of the seller. I was commenting on the easy to see fails in the sale post. But trust me, i've heard enough so far about him to get a glimpse of the base individual we're starting with. I trust you're opinion of Sanford and Son is on point. Quote
Zacharysalis Posted April 25, 2014 Author Report Posted April 25, 2014 So is there anyway I can check without tearing the whole engine apart Quote
WINDYCITYJOHN400 Posted April 25, 2014 Report Posted April 25, 2014 Pulling a head is not tearing a whole engine apart. It's SLIGHTLY more work than a jetting change. Learn to wrench early....it's better than wrenching later. Quote

Nieskes Posted April 26, 2014 Report Posted April 26, 2014 Drain coolant. Pull head pipes. Disconnect coolant lines from head. Remove head nuts. Remove head. Read #s on top of piston. Report back with #s.Or take the plugs out and look with a light/borescope if he is lazy. Quote
