+8mm crank

[RaptorRandy]

Well i guess im the other 10%  I built a cylinder riser to fit my crank and only flycut deeper eyebrown in my piston that i have had.

I was just fixing to ask if you were running a spacer under your jug when you were posting that

I agree preddy. Im not going to go cheap thats for sure. Im just trying get outta someone if boring to a 105mm and 14:1 piston would be as effective as stroking a stockbore with 14:1 piston. if i can achieve the same results without splitting the cases i would like to do that.however if im going to gain a shit load of power and performance to bore to 105mm,14:1 piston, and stroke it all together i may go that route

Yes sir I do. But that us the only way you can get away with a stroke that big and the rod length that i have. If you go to like a +4mm all you have to do is run a stroker piston. Anything else is stroker piston and shorter rod, which i didnt want to do. I know that you are aware of this Randy....im just saying it for other people.

[RaptorRandy]

Damn....I must be goin blind....I just saw you had 1/2'' cylinder spacer in your siggy.....

[White Rider]

I just made my sig. Im a newbie So ur not all that crazy.....haha

[RaptorRandy]

ok, I guess I'm not going blind yet 

Glad to see you over here

Thanks, i just got a PM about it and said what the hell. It seems like a really good site.

could i start with boring to 105mm and install the cp stroker piston now. and if thats not enough than down the road install the stroker crank. This way i wouldnt have to buy another piston down the road if i wanted to make it a stroker

I think you'll like it here, it is an excellent forum

If you put the stroker piston on the stock stroke and rod your gonna be down in the hole and give up a good amount of compression.

If your gonna just bore it for now then I wouldn't run the stroker piston then when and if you decide to go with the +8mm crank I would do like Troy suggested and get a -4mm rod installed on the crank and have it trued ,welded and balanced.

But to me it makes a lot more sense to just save up and do it all at once and be done with it if you are really serious about stroking it in the near future.

If you will even have enough to detonate.....I wouldnt reccomend doing that. Go 105 then later on down the road get a stroker crank and piston. But if it were me i would do it all at once so you dont have to buy a piston twice.

Raptor randy, what would you recommend.I dont really trust my local machine shops to much. so im looking at what ever is basically a drop in part.i dont mind sending my cylinder out of state to have it bored and sleeved and upgraded for bigger studs because shipping is cheap that way. but i dont want to have to send my whole engine out. so would i be happy with just boring 105mm and 14:1 piston based on my mods in my signature? or hold out for the bigbore-stroker. I trust your judgment randy.

[1badazz_700r]

white rider i would rather do everything at once rather than buy 2 pistons actually would be my 4th and 4 tear downs. I want the next one to satisfy me for awhile dont get me wrong it runs like a mofo right now. im just weighing my options to see if its worth doing another rebuild. I just want what ever is the least amount of machine work. Thats why i wanted a drop in stroker crank and just send my cylinder out to be bored

[preddy08]

From what I have seen JUST boring does'nt really do a whole lot. Maybe a few ponys and a some down low TQ. I think you will be disapointed once you get it runnin. I would just save up and do the bore/stroke/piston all at once.

Did you ever think about the +5 hot rod crank. Its a cheap alternative. Troywcc came to my parts last weekend and his bike is about the same build as mine, but he had the crank in his. He was constantly 2-3 or more bikes ahead of me.

It's hard to say....it's definitly less money to just have it bored and get a 14:1 piston. The 727's can run good and hard with the right combination of porting, cam, piston and custom advance curve. But if your even thinking your wanting to stroke  it,  after some time your probably gonna wish you would have done it in the first place. It all depends on your budget and what kind of HP & TQ your gonna get out of it.
