Hi everyone. My wifes bike came back from the dyno last week with numbers I thought were lower than expected but I've had few guys tell me it was a good number. It's a 06 xl1200 with se536 cams, Sampson 2-1 and a tc88a. what do you think?

SE Cams??? Well, thats the first bad mistake. Woods, Andrews would be a better choice. My bike pulls over 105hp and 94+hp torque... But those numbers aren't that bad IMO, unless of course you want to heavily modify your bike, spend over 5k in engine work, like I did! Well, per se, I didn't spend that much but the previous owner did...

 

I think those are good numbers. You should be happy with that.

IMO beware the numbers chase. You can spend a lot of money for bragging rights, and most people never ride in the range that those numbers start to kick in.

 

Bizaare
I spent under 2 grand and I bet I hit 100 hp

 

I learned a longtime ago Not to chase Dyno numbers it appears not all dyno's or the technicians that run them are the same, to truly get somewhat of a good idea of what the numbers are it takes three different dyno's with three different technicians at three different locations and even then the numbers will not match but it should give you an idea of what they are..

 

Those are very respectable numbers if all that is on the bike is pipe, air cleaner and some chicken cams. nice job. Sampson caliber pipe?

 

chicken 497, 536 and 575 cams are some of the best out there. Andrews cams suck. They have the n-4 thats proven itself, the rest suck except for a few big lift cams for monster engines.

Please enlighten us on what andrews and woods cams will go into his 06 1200 with stock valve springs? besides the n4 and crappy n6

 

I disagree somewhat. There are a lot of variables...thats for sure. On my hammer builds i am with in a few hp of what they tell me the bike should bring.

Maybe i should say this, there are a lot of shops out there with dynos......cough....hd shops that dont put a full tune on the bike. beat every last once out of it.

The dyno is a tool for tuning. nothing wrong with chasing numbers as long as you keep using the same dyno. Most guys give up on the dyno chasing numbers because it can get expensive and most fail at it.

 

Yes, it's a caliber. I was thinking of putting a HSR42 on it but the dyno guy said I'd be wasting my money. He said I'd be better off with some headwork and different pistons and then showed me a bunch of their "flow" numbers from past customers heads and also showed me the dyno results after. He was pretty confident I could see low 90's for HP and mid 80's for tq. What do you think? Is he blowing smoke or?

i think a 42 mikuni is a great idea for any bike....mild to wild. He can put you in head work then you have a stock carb that will work but really wont get full potential from the engine.

I could care less about flow numbers......you can punch a hole threw a garbage can and it will flow big numbers....doesnt always mean it will make power.

He is blowing smoke....haha.......with that pipe, a 42 mikuni, your chicken cams matching pistons to good head work that bike capable of a 100hp plus pretty easy. Esp with 1200 rubbermount heads.

Im partial to these guys but read up on this. These guys deliver power in any level you want and its pretty good bang for your buck.
