I kept my rebuild from 883 to 1200 SIMPLE....
THIS IS WHAT JERRY BRANCH (BRANCH HEADS IN CALIF) SUGGESTED for MY low budget rebuild....
I wanted LOW END TORQUE and BOY DID IT HAVE THAT when finished.....
***** ***** *****
I used wiseco 10.5/1 pistons ( An 883= 3" piston a 1200=3.5"piston) a big difference!
BOT new HD 1200 cyl's barrels....
boring out the 883 is not practical $$$ (3" to 3.5") as i could BUY NEW 1200 cyl's from harley for LESS than a shop charged to bore them... and KNEW the cyl's from HD were properly done and ready to go...
LAPPED the valves by hand to clean and seal....(used stock 883 heads and not modified) they work really well with the wiseco pistons as they are built to work with the stock 883 heads
USING REGULAR STOCK HD carb...JETTED it properly(? 165/185 main?) and installed the OLD style-sized 1200 sporster NEEDLE ? part #?(stock needle from the older ? 1200) someone here will know the # and will let you know....TQ maybe?
PUT THAT all together and used (old style) scrm'n eagle exhaust slip-ons and scrm'n e air cleaner...
NOW MIND YOU ,,people will suggest CAMS but when I asked JERRY BRANCH " now how about cams?" HE YELLED " there you guys go again,,,,, wanting all that low end power then you go CAMING IT OUT!!!!!
JERRY BRANCH said "put it together like I said,, and break it in then GO find a POLE to climb...... THEN call me back!"
I went with the above and the only advice i give you IF YOU FOLLOW the ABOVE is
HOLD ON TIGHT WITH BOTH HANDS it will climb a pole......
YOU can pull up all my post under BUBBIE and WEED thru for the stories on my 1200 rebuild....
HOBBIT MAY weigh in her about the gear ratio change IF DESIRED of which the stock 883 was JUST RIGHT FOR ME....
HOPE THIS HELPS.... and don't forget to use the 30/60/30 X 10 times method for "breaking in a new motor" found under SELF HELP on this site.....
THIS WILL SEAT IN THE RINGS RIGHT THEN!
