laporta682 Posted September 2, 2013 Report Posted September 2, 2013 newbie here on my first banshee coming from a 686 raptor, I traded the raptor for my banshee and 2 weeks later it seized up on me.... pulled the motor and my crank was jb welded together and both pistons exploded. I had a local mechanic who specializes in banshees rebuild it with a hot rod 4 mil stroker crank and a ported & polished head to match the 4 mil with a .20 over bore. I also have full t 5s and white bros boost bottle. what should I expect as a power difference? will it be faster than my 686 raptor? how much hp should it be making? Quote
CAJUN BANSHEE Posted September 2, 2013 Report Posted September 2, 2013 Hurry and search boost bottle on here before (the wolves) find this. Welcome Quote
Deadbeat Posted September 2, 2013 Report Posted September 2, 2013 dont suppose you have pics of the jb welded crank Quote
laporta682 Posted September 2, 2013 Author Report Posted September 2, 2013 I do not have pics sorry, I didn't even want to look at it any more than I had to lol Quote
laporta682 Posted September 2, 2013 Author Report Posted September 2, 2013 it ran pretty strong even with the crank jb welded, I was impressed Quote
Deadbeat Posted September 2, 2013 Report Posted September 2, 2013 didnt your banshee specialist mechanic mention how much power you are going to make after he has rebuilt your shit? Quote
laporta682 Posted September 2, 2013 Author Report Posted September 2, 2013 it's not like he has a dyno... I figured I'd get a better idea from the forums Quote
special06shee Posted September 2, 2013 Report Posted September 2, 2013 A 4mil motor should make between 30 to 120hp. It all depends on how it was built. Honesty, with with the info you have given, id say you'll be at 45-50 hp Quote
hughmyron Posted September 2, 2013 Report Posted September 2, 2013 (edited) Boost bottle you say? Should leave you at like 90whp. Edited September 2, 2013 by hughmyron Quote
RagunCajun Posted September 2, 2013 Report Posted September 2, 2013 The person who ported your juggs will be able to answer best. If he cant, you should of had him do your engine work. Give him a call tomorrow during business hours and find out. As for being faster than another bike, line them up and find out. Quote
jbooker82 Posted September 2, 2013 Report Posted September 2, 2013 are you shure it wasn't Yamaha bond on the crank? Quote
Nightmare Posted September 2, 2013 Report Posted September 2, 2013 Jb weld on the crank? Ya hear a new one everyday:lol: Sent from my SGH-T679 using Tapatalk 2 Quote

laporta682 Posted September 3, 2013 Author Report Posted September 3, 2013 it was jb welded. I'll post pics when I get it back someday this week Quote
ban565 Posted September 3, 2013 Report Posted September 3, 2013 I had a 4mil stock cyl drag ported that was to be between 75 to 83 hp. Raced a few 686 and never lost. Quote
