oil

Jeremy

Have you drop oil in your piston for storage? If yes you can end up with more compression.Crank it a few time without plugs to free up the oil and to fill your gas pump and carbs.This take about 20 crank to fill.After that it should fire up.

 

[RudeAwakening]

yes there has been lots of oil put downthe spark plug holes

just checked the compression in my engine! both cyelenders were 92lbs.
the rings and the pistons are new to this engine and engine has not been fired up yet.

 

[buffaloHAWK]

only 92 lbs? thats doesnt sound right

 

[cjgodden]

Brand new motor, It probably just needs to be ran and the rings need to seat. You can't do a compression check on a brand new rebuild like that.

 

[RudeAwakening]

ok! i will have to let it run for a few hours

 

[Hawkified]

when you did the compression check how many times did you pull to get 92lbs. I am no expert but I just rebuilt my motor and it had 150lbs in 5 pulls with throttle held open on each cyl before it ever ran

 

[RudeAwakening]

pulled it about 10 - 15 times
but never touched the throttal. do you think my compressonn would have been higher if the carbs were wide open?

comp test

you should always hold throttle open when doing this test because it allows maximum air intake. On that many pulls you should have more comp. than that i'm sure. I check my 600 and had 140 lbs in 3 pulls.

yes, you have to hold the throttle wide open. it makes a big difference.

 

[RudeAwakening]

i dont have the compression tester anymore. i borrowed it from a out of town friend wen he was viseting. you guys think im probley ok then? someone do the test with the carbs closed and tell me what your #s were.

 

[J&L Snowhawk]

don't worry

if it starts and runs quit worring about it and pin it wide open and hang on.

Just run it.. It wont start if the comp is really low. let the rings set and do it again if you want.. getting another reading from someone else wont help..
You have to open the throttle wide open.. 3 pulls is the standard..
with the throttle closed your chocking off the motor and will get inconsistent results..

my new 800 jaws pipe and the rad i think im gonna use

this is just a pic of a snowmobile show i had a little booth at.

 

[cjgodden]

That pipe looks alot like the stock 600 jaws pipe, Do you still have the origional?

 

[RudeAwakening]

no, i dont. its thicker and seems like its been built a little better. can is way lighter too.

 

[cjgodden]

I was just wondering about the dimensions, length, when the chamber starts, length of chamber, ect. Too see how close they are. The can is definitely different, looks to be lighter. Sure wish I would have had the money to get one. Oh well maybe later in the year.

 

[off road rider]

I like the rad with the both ports on the top.. you will have to add a cap up there, as thats now your high point..Sweet Pipe

 

[RudeAwakening]

i thought i wouldent need a cap, what would happen if i dident add one?
