Stroker Motor Question?

[cloeter]

Hi guys,

 

I bought me a new wiseco 4mm Hotrod stroker crank and a set of 1.5 oversize wiseco pistons. My question is what size domes do you think I should use on the head, and what should the expected horsepower be on the current setup???

 

4mm Hotrod Stroker Crank

1.5 Oversize Wiseco Pistons

FMF Fatty PowercoreII pipes

Standard size carbs

Coolhead 19cc domes

Reed Valves

Prow Flow Airfilter with no lid

Ported as well

 

Will I be in the mid 50's hp and are the 19cc domes a good setup or should I go bigger?

with that setup and a nice port job you can very from 50-80 ????

You need to have your domes cut, to accept the pistons, because the pistons will come up out of the cylinders 2mm, and hit the domes, if they aren't cut. 18cc or 19cc domes should be fine, once they are cut.

Didn't want to see you destroy a brand new top end.

Depending on your porting you'll either need some new cyls or some new porting. If you just drop the crank in I'd say you'd get MAYBE 2 HP more than a stock stroke crank. If you get the porting to match the +4mm, then you should be able to get up into the high 50's at least.
