Can any one tell me what is better I heard that an 89 cr 250 gasket is thinner and will give more comp. I also know that if you take the stock head gasket apart and use the thinner one that works too!!

But what is better??

Thanks

 

go with the 89 cr type i was told that would raise the comp between 5-12 lbs,,
spliting the gaskets the way u said , works but its a waste

 

I swapped my stock gasket in favor of the CR gasket in the hopes of more compression/power but I honestly didn't notice any difference at all.

 

dont forget to put the big hole forward or it will over head the exhaust side

 

yeah ...what they said. trx=3piece, can take apart,atc=thinner than trx (all 3 pieces),cr250 very thin,best choice. my bike went from 180 to 195 going from trx to cr gasket. can be tricky to seal,had problems last time with gasket though.maybe i did have the hole facing wrong way DE DE DE!!!

 

you could have me cut orings for $ 75

 

put a long piece of solder in the spark plug hole against the wall and head, roll it over to make sure it has enough clearence

 

Ok Thanks

I opted for the 3pc I am goin to take apart and use 1 of the thin ones this way i have 2 for price of one. hehehe

Now hopefully when I get it back together I can get this darn jetting figured out.......
