Thinking of upgrading my 883 to a 1200 or 1250 . Any advise on doing this? Should I even bother or how reliable is the bike after the upgrade. Is there more to it then swapping pistons and cylinders? What else would I need to change on the bike for the kit to work correctly? I would love to upgrade the bike but the money is not there right now.

Here's how to install it: http://hammerperf.com/ttinstallkit.shtml

Reliability is just as good if you install everything properly.

 

Ping member Hexnut. He just recently converted his 2014 883 with good success.

 

I have to give HammerPerf a big thumbs up too. Aaron & Dan have
been great. My 1250 'upgrade' (crush-ported 1200 heads/cams/30deg pistons/etc) kit is on the way. I'll get some pics of everything
when it gets here.

Go with Hammer. Those guys are great and very helpful. I with I had put this kit in sooner. It runs great with much more power. I have had no issues with it. I put in 1200 gearing to cruse at a lower RPM. You don't have to do this. If you leave the 883 gearing in it will make your bike take off much quicker. You will need an energy one clutch.

Just follow the direction and don't take short cuts. I had no problems. If I can do it at 72 years old you can.

 

does the clutch kit come with the big bore kit or is it ordered separate

 

It is separate. Best advice is to go to the Hammer website
and spend a few hours reading the weath of info they have
available about the conversion.

We also have a couple of threads in here by members on their 1250 builds, which are worth seeking out. Your first purchase should be a factory service manual, as that will provide essential guidance! Use Advanced Search for '1250' and have a browse.
