Kuda, next time you talk to the builder or owner of the
Engine you have, ask him which rod is in it. Stock or what year of 250r. I noticed in the pic of the piston of the cylinder if at TDC (Top Dead Center) there was a lot of deck. This may account for some the low comp reading. Before you install a head on it set it at TDC (Top Dead Center) and get the measurement from top of cylinder to top of piston edge and then run it to BDC and measure from the top of the cylinder to the exhaust and intake port opening. As an alternate number place a flat piec of metal across cylinder and run the piston up from BDC untill it touches the flat bar then measure down from top of cylinder to top of piston edge and measure crushed thickness of head gasket and the ID. This of couse if you have time. I know your busy. With this info I can start to figure about where you CR is Just curious. DO you know what rpm you comp reading are taken at. The cylinder look like a poloris 400 modified, any info there.
Thanks, Adnoh
Adnoh,
Both motors have 350 jugs,the 360 has a 350 sleeve the 420 has a yz 490 sleeve
This I know for sure, I may not have had the
motor ((
Internal Combustion Engine ? )) TDC (Top Dead Center) for that pic
Here is what I know about the 360 that I am working on now.
it uses a 350 .40+ 533p4 piston,coated witha window cut in it
custom liquid cooled jug and head
both motors use stock 350 connecting rods,although the 360 has a hot rod in it
custom built head... both the heads I have coming have different size chambers
I was told One with be good on pump gas{93} the other may require race gas{110+}
lots of port work was done to the jugs
The problem is...The original builder of the 360's was Bob Victoreno
what I had planned on doing maybe is seeing if you want to take a closer look at these?
Once I have the motor (( Internal Combustion Engine ? )) together and running proper I want to start on the 420,..But if you want to take a close look at one of these motors at a time
we can make it happen, If you get a chance,give me a call and we will talk on it
As far as my time is concerned, I am loving working on these things
I feel like a kid again!!!
hoser mentioned having them blueprinted??
you up to it?
KUDA
I can't get a hold of him..Not sure if he is still around
Yes make him blueprint them he is good with these type details it would be great to document so if others wanted to build one in the future they know what needs done, we need to start documenting all the Pilot Odyssey history we can before its all lost for ever.
