well if we are collectin comision checks I am thinkin I should be first in line right dave??

 

 

I would get the 115 rod 4 mill crank from jeff, have the cylinders ported to match and get a set of domes cut for your head. I would also run cpi pipes for a dune motor, my friend has jeffs dune port 350 and it holds its own on the drag strip, and it is a blast to ride around in the dunes!!

I currently have a dune port on stock jugs and crank. Would a 4mil stroker crank and reporting it to match the changed timing/still dune port, make it easier to ride. I mean is it less work on the rider. My wife likes getting off her raptor and jumping on mine time to time. Would the 4mil be easier for her to ride. She can handle a bike real well, she just doesn't like the hard power hit. Would the 4mil broaden the power delivery over a larger rpm range. Can you lug the motor a little more and have it respond compaired to stock stroked dune port?

A stroker crank will give you a little more torque and HP, so...yes it would make it easier to ride.

It will NEVER be four stroke easy to ride, especially a big, torquey 4 poke like the Rappy.

 

What kind of pipes are on there now? There's plenty you can do to make it easier to ride. Compression, timing, gearing, etc....but, it'll never be a 4 stroke!!

Hey Dajogejr. I have dune port on 20 over wiesco's stock crank trued/welded, t-5's,vforce2, 30mm knock off pwk's, fireball billet intake, +4 timing, cool head, has 18cc domes, but with the porting heights i can still run 93 octane. running 15 tooth front, stock rear gear. +4 swinger. She likes the speed of the banshee but after the port job it hits a little differently than it did before, she wants a little more over all so she's not always clutching it and shifting. It's fine for me, just trying to make her happier, plus if i can sell the idea to her, she will let me spend the money. But if it doesn't do what i say then i'm up a creek for spending money in the future.

I'd be double checking my compression, depending on your altitude...

Stock timing anywhere near sea level, you're going to need at least 50/50 race/pump gas if not 100% race fuel with 18cc domes, even if you had a WIDE OPEN drag port, I still don't see that dropping the static compression to a range I'd feel comfortable running 93 octane in. And...you advanced your timing as well.

 

Check that compression pronto!!

 

However, if you're above...say, 3000 or 4000 ft, then I'd think about it....

 

Unless you're going to choke it down with a 2 into 1 pipe and 1 into 2 carb, etc., then you're simply not going to get much more bottom out of it....period. Dune porting hits a little higher in the RPMs, just not as high as a drag port.

 

Since you've got 18cc domes and a timing advance...porting, pipe(s) and carbs are all that's left to get more bottom....
