Hey all,

So I've been reading through some threads but I seem to be getting a little confused on what it is EXACTLY to do to increase the performance on a 1200C. On the 883, it's pretty simple. Buy a 1250 kit and you're good to go. But for a 1200, is that the way to go? I can't imagine that an exta 50cc's would really make that much of a difference. So what does that leave? New heads? Cams? What is the first step in that process? Just to give a benchmark for performace, let's say I'm going for 100hp for arguments sake.

I've already got a stage 1 upgrade which certainly made a difference, but certainly nothing like the jump for 883 guys to the 1250. Thanks in advance for all the help. I know you guys won't let me down!

Are you sure you want to go for 100HP? It can get pretty expensive. Check Hammer, they can get you there.

 

Cams would be the next logical step, and the last of the easy "bolt on" options.

A 1250 kit on a 1200 is still a huge upgrade. Has more to do with combustion chamber design, flow, and compression ratio than a displacement increase. Also, there are differences in the heads between the 883 and 1200. This means all other things being equal, a 1250 upgrade on a 1200 is still going to make more power than an 883/1250.

No not really, I'm just using 100hp so you guys have something to go off of.

Ok so a 1250 followed by cams? Or cams then 1250? Thanks for the info though, I'll give hammer a look

 

Cams first. Hammer will answer all your questions and lead you in the right direction. If you plan to do a 1250, you might also consider valve train upgrades at the same time, which will allow for other cam selections. But.....

You should also do the the best upgrade not mentioned enough.
UPGRADE YOUR CLUTCH.

 

Yea I've built some performance cars with over 600hp so I know the need of a good performance clutch to handle the increased hp. I just want to know the order of upgrades in order to get all my thoughts together haha.

Any particular brand of clutch upgrades or will the harley upgrade suffice?

Actually same question for the 1250 upgrade. Is hammer or nhra better than the harley one? I know the harley upgrade will keep my warranty intact but if it's not as good then I really won't care.

 

Most here would agree that Hammer is the way to go. Top notch customer service and support.
As far as the clutch goes, it is a fine clutch for performance, but has a riveted plate in the center of the pack that is prone to failure. More power just means it might fail earlier. Not with the risk, replace it before it happens. You can replace the entire pack or just eliminate the rivet plate with two steels and a friction plate. There are a thousand threads on the subject.

Your upgrade path should be
clutch first,
Then cams,
Then 1250.

If you are going all out ($$$$$), you'll be doing cams, valve train, head work and 1250 all at the same time.

 

100 HP comes pretty easy but not Cheap !
The pipes you have wont help the cause however.
Clutch ? I love my Alto Carbonite lubed with Royal Purple 20W50 MC
You should have a good tuner like the Power Vision
Big *** Air Cleaner like a Hurricane Flow from NRHS or the Air Hammer from Hammer Perf.
The 560 Cams from Hammer Perf. are bolt ins.
Next we think about head work and a 1250 kit with 10.5 compression and 30 degree squish bands.
Theres your 100 plus HP
Contact both for package prices.

 

Yea that's why I'm not really worried about reaching 100hp. The look of the bike is exactly where I want it. So the pipes are here to stay. All I need now is the power to back it up haha.

But essentially a new cam, 1250 kit and clutch and I'm good to go. Seems like a plan. Oh and a tuner with someone competent enough to dyno and tune it haha.

 

The Dynojet Power Vision is pretty damn good !
You MIGHT get to 100 HP without doing the heads.
