I'm not sure I have the energy to have a "Which Big Bore" discussion [img]i/expressions/face-icon-small-blush.gif[/img]

............but since the thread originator asked............No sleeved big bores. The DS cylinder is not made like other cylinders that have good luck with sleeves. The Rotax has a high failure rate. Your options are the HPR or Pami............Nothing wrong with either of these options as far as performance is concerned so I would say price is about all that is left as a determining factor[img]i/expressions/face-icon-small-smile.gif[/img]

Ah!...........The good old days[img]i/expressions/face-icon-small-happy.gif[/img]

ENOUGH SAID[img]i/expressions/face-icon-small-wink.gif[/img]

 

Only if you want a 70 horsepower stock bore with shelf parts.

 

Are you attacking me? Im gonna report this to a mod....................Just Kidding[img]i/expressions/face-icon-small-happy.gif[/img]


But no, you could get in to a Pami 725 Big Bore, or the 703 or 710 or whatever they are, Stroker Motors for that kinda money.

 

Dang thats pretty good!

 

And you can take that to the bank. NO special cam grinds, no special lightweight piston, no special cnc porting. [img]i/expressions/face-icon-small-wink.gif[/img]

 

You got that right Goodsound if your heart it set on a stroker he can help you there too. Proven on more then one motor without nitromethane.

 

You people crack me up. Jeff must be really hurting for work. I bet he looses more work from you people than you help him. I spend my money with about every builder there is right now, exept Jeff. I surely dont want to be a part of his crowd, if this is how they act.

You folks want people to be subjective, and let everyone express themselves. But jump on anyone who chooses elsewhere, and then call them hypsters,lol. What a joke. I sure hope you can look at yourself in the mirror, and feel proud of who you are!

Hey Jeff, hope your happy, these are your salesmen.

Hey Choose, since your puting your two cents in on who to spend money with. What is your experience with pistons and cams? What, and who's stuff have you ever ran? Have you ever installed a set of cams, or piston in any bike? Just want to be sure of your experience.
