my link is to my site which shows my friends quads and a place for us to talk.



<< Lets just say for 2 seconds that you are right. So the bore squeezes down on the piston some. This would not wear the rings any faster, as this is why there is something called ring end gap. The ring end gap will squeeze .0000000001 tighter, end of story. >>



you just dont get it. the bore doesnt squeeze on the rings, it wears faster because of the slower contraction rate, which YES does make the ring gap tighter. it is more than .00000000001 and that puts more tension on the ring and wears the rings and bore out faster.



<< I would never take advice from a guy who thinks a Mac500r will be a good trail riding bike with a +1 swingarm >>



ha, dill actually had that motor with a stock 88 length swingarm with some destroking I think it will be a very capable trail/dune/mx quad, we are building it either way.

 

Im runnin 22:1 redline

 

can we all agree that a forged piston expands and contracts slower than a cast piston?

Oh I see...the rings just wear from some physics formula that nobody has ever heard of but you.

I sure did..and this motor IS NOT, a trail motor, de stroked or not. The vibration is a very real issue, (the plastic on my quad vibrated so much it sounded like a huge vibrator) and the power of it will probably end up hurting someone with only a 1 over swingarm. I ran it with the stock arm, but honestly, I was scared to take it on the pavement where real traction was available. It just spun ALOT on the dirt.

 

Robert106, glad to see you're still an active part of this forum. I was starting to doubt if you would ever get that thing running again.

Congradulations BeeRock69. You have just joined the list of people active forum members ignore. You also won the prize of talking in circles. Every statment you made in your 1st post, you have since discretided.

 

lol lonestarbanshee. thiers was only 2 posts to this last time I saw it! I was like what? 2 pages already damn!

 

yay lonestar,
but I stoodmy ground and did not discredit any statement, I did however add to it or REPEAT IT Over and over.

dill, what gearing were you running on this bike?

I was thinking of playing with the gearing to tame it.

 

Yeah buddy, you're a real conversation starter [img]i/expressions/face-icon-small-smile.gif[/img]

 

I started at 14/38. I went to 15/37 which helped the spin some, but it still had quite the hit. Keep in mind this motor was 'recreational' ported, not drag ported. It also ran a Wiseco piston ;P

 

22:1 is a little rich with redline oil, its a full synthetic, they claim you can run 80:1 or 100:1. Ive heard of people doing it, but I wouldnt recomend it, hehe, I usually keep it around 32:1 or 40:1.
