    CL1 cam and GX140 valve springs?

    With the 10.8lbs they are speaking of can achieve 7000+ rpm with that cam... Now speaking on that... those said springs will only last 1-2 race nights at that level before they get switched out... That is a AKRA box stock cam, for that spec class...

    non-hemi rod question

    Because I use the Honda crank you use a Honda Rod... yes the wrist pin in the Predators is the same as a Honda... The reason I mix and match parts is because I do a lot of Kart racing, and the engines blow up on a regular basis... So what ever left over parts are in the bin I use to build...

    non-hemi rod question

    By going a .020 over rod and a Hemi piston puts you at the same place as the beginning... If you use a .020 over rod and the stock dished piston would move you up .020... In the Non Hemi I always use a .040 rod and a Hemi piston... ends up right around .020-.015 in the hole... then adjust the...

    non-hemi rod question

    Most if not all non Hemi engines are a minimum .040-.050 in the hole... they have a taller deck height than Hemi or clones... That is why ARC came out with the 2 different rods... .020 for Hemi, .040 for non-Hemi...

    non-hemi rod question

    All the non Hemi engines I have built used the .04 over rod..especially if using the Hemi piston... using thin head gasket Even the Hemi engine I use the .04 over rod with a thick gasket... Now if putting a Predator crank in a Honda... I use the .02 over rod... This is what I have found...

    Installing GX160 lifters in the GX200?

    Why are you so concerned with weight??? You say you want stronger pushrods??? What is wrong with Honda pushrods??? They are pretty darn strong and lighter than the moly ones.

    Installing GX160 lifters in the GX200?

    I usually run them when the head is milled .100 or more... ran them for seasons at 8000+ rpm... stock Honda pushrods... no issues... Really depends what ya have around to build a motor... Never used them because they were lighter though???

    +.175 stroker crank and UT2 piston in 196 clone.

    Yup... all of the Honda, Clone, Predator... blocks have been bored to various sizes... Honda by far is the nicest block... You can pick up a new bare Honda block for $40-$50... I usually run them a season or two before I bore them out...

    1.3 ratio rocker on intake only?

    Also when these engines were designed... it was for a generator or cement mixer running at 3000rpm for a typical 8-10hr work day... So they intentionally engineered a larger exhaust to help promote cooling...

    New cheap carb Nibbi 26mm PWK copy

    We are using 14" WC... with a 200cfm orfice... I thought it should flow more than 100cfm... I wish I could have found a 250 2 stroke instead of the 250 4stroke... Nice Kart... I kept the tranny and added a shifter and clutch lever to the kart... Just got done tuning the carb... it was a bit...

    New cheap carb Nibbi 26mm PWK copy

    Wow, I am impressed with the flow of that carb as well... I just switched over to a Yz250f motor on my Kart for UAS racing...it did not come with a carb, so I used a Mikuni SBN 38mm carb I had... I flowed the carb and best I could get out of the SBN was 100-105 cfm... It looks like from your...
