also used on some polaris

i run n2c or n3c champions myself in all my jds.

2016

intake is /3 covering is /2 at a guess probably a 400. as for the fan comment jd ccw fans were all the same differences were 1 bolt on the top for engine cover and the plastic fan cover. I hate to argue but if jd used /3 and /4 the fans are different I have both and a manual to back it up. go ahead...

its a t7 crank needs a rebuild though.

lightly blasting springs is fine sand blasting them heavily can sometimes lose tension in springs. Blast them so that have heavy rust removed but are still mostly brown looking paint with rust paint enamel. powder coating is good for furnature not very good on stuff that moves as its brittle.

Raiders used 400 ccw and 440 reed valve mercs used 340/5 but went to 440/22 instead of piston port. There was some other 1 year sleds that used this engine but they are impossible to find.

Since its my favorite engine i know it rather well.

found in 600 74 75 and 75 500.

The absolute best is pure mink oil but this is impossible to get. Next up is needsfoot oil available from leatherworking supply places.

If while reading ingredents it says silicone on it dont even go near it.

I get most of my parts from sun&snow/rec supply/ or a kimpex dealer. Bearings I usually go to enns bros in carmen its more gas but i never have a problem with them. Crank bearings i order from a supplier they are good quality. Other stuff i have to make myself as its unavailable or the quality i...

36 and 34 use different seats.

You should see what 600 cc does in the same sled its...interesting. a guy i know fitted a set of cylinders from jetski on one.. wow that thing was super fast... dangerous too. also something to check out if you ever encounter one is the 9700 blizzard racers 82. rare as hell but interesting none the ...

i have to ask on the end of clutch is there a 3/8 hole on either side of shaft? there was a couple that were actually screwed on cranks pulling these with a puller will only ruin puller clutch and sometimes crank.
