Re: four corner scoring on piston
How long does this s*** have to go on? It's just a commonly used term to describe the condition of a round piston :roll:. What happened to the days when someone asked a question they actually got help? WOW! Common my butt. No one with half a brain uses the term corner to describe anything to do wit...

Re: four corner scoring on piston
155psi for compression is to high for pump gas. You need to add a head gasket and lower that compression. As for air leaks, the common area is the exhaust flange where it connects to the bore. I use the Mr.gasket exhaust paper sheet and cut my own. You also need to retighten the nuts a few times. A...

Re: Deuces 450.00 Dolla halla Build 2000 Elite SR
Thanks for the input you 2.. What jetting sizes should I order to tune this carb(26mm oko)? I got the tach in today, what a great tool to really dial in your a/f for idle. Wow, I am loving this. not sure on jets for the 26mm carb, but a good place to order them from is rocky mountain atv thru amazo...

Re: four corner scoring on piston
Sounds like your midrange is running really lean. The air fuel screw,needle and pilot jet all tune that area. But that 155psi compression and running 93 octane pump gas is your reason for it running hot. You jet it rich or run a lot of oil and it will still run hot from it knocking and pinging.As f...

Re: four corner scoring on piston
Greetings: 155 is crazy-high for pump gas, Dawg. I was running 125 or so and still managed to hard-seize after a long coast-down using 60/160 jetting. Your jets aren't as big as you think for that setup. Baka-san recommends beveling the piston skirts and ball-honing the bore to remove oil-scraping ...

Re: four corner scoring on piston
baka, i didnt want to quote the last reply, would be pretty long. so you dont think has anything to do with plug or port duration? what about carbon build up on underside of piston. i also had a little blow by on the rings, on intake side. had bout 300 miles on kit. i did chamfer all ports and pisto...

Re: Deuces 450.00 Dolla halla Build 2000 Elite SR
id go with the 43.2 mini stroke, i have 44.1 and its been kicking my * since the day i put it in. hard to get port timing right and prob have to run a few head gaskets to keep compression down. shorter stroke would reduce the need for multiple head gaskets, unless you like having to re torque head d...
