883 to 1200 conversion

[redeye]

Is it worth it? And if it is worth it, which way should I go

screaming eagle with a cost of about $553
or
V-twin with a cost of about $422.

This is a 98 sportster and I usually just use the bike to go back and forth to work. About 400 miles per week.

I dont have much expierence with thsi but a few of our members did it

I'll move this to the Sporster forums so you get more attention

I know it runs like a raped ape if you do the cam & a little headwork to it

Would I do it, Yep

Whichever you decide, be sure you get the correct pistons to use with the 883 heads without head modification.

[redeye]

Neither way should require head work. They say either way is simple bolt on. How simple, we shall see

[McMike]

you will see a big improvement 0 to about 70 or so, if it's done right you should be faster to 70 than a stock 1200.

If you don't do the head work, it won't run on anything but racing fuel. The combustion chamber on the 883 is egg shaped . When you put 1200 pistons in the chamber will be too small. I had someone do my heads. I cc'ed them to 9.6:1 . I have to run on 93 octane or better.

I thought this is why the new pistons were reverse domed.

Redeye you are correct,dished pistons for stock heads.
I recently did all that.....be warned its very addicting.Just pistons and jugs ups the hp alot.But you will still be leaving some horse's on the table.As money allows stage 1 or 2 head work and since the heads are breathing better some cams help alot.ok so now ya need a ing. mod.I put in a dyna 2000i. with a accel singlefire coil.Then you will want a good exhust(thunderheader)
Do you have to have all that?Nope but the other stuff makes everything elese work better.
attached is a graph that shows stock,then each mod.,etc..

If I had to buy a new sportster all over again I would probably buy an 883 and do the conversion instead of buying a 1200 at first. Cheaper bike price, cheaper insurance and if it's true what they say, the 1200 conversion is quicker than a 1200 stage 1 stocker?

Ok, so far you all say I should do it, but nobody has said yet if I should go with the v-twin or the screaming eagle
