Hello all, Guess it's been awhile since I last checked in. I recently picked up a "barn fresh" pair of TF's that are actually in pretty nice shape. (pics tomorrow) Crank seals, chassis bearings and lube the suspension crossbars (all preventative, the sleds both start and run) and they'll b...

The significance of attempting to add reed induction to a piston port engine is to 1) Increase rideability while adding dual carburetors. If you open up the intake tract by 2,(dual vm34 carbs), you lose low end response due to fuel charge velocity. This mod is intended to regain that bottom end whil...

"Better Power" is an ideal choice of words. As the bottom of the piston skirt travels up past the intake port, it of course creates a vacuum and sucks in the fuel charge. On it's way back down it then forces this charge through the crankcase and up through the transfer ports. Unfortunately...

Looks like adding insult to injury to me. I quit reading it and will refrain from derogatory comments.

Thought I should show one of my "top secret" ported cylinders from a jetski with the reed adapter and dual SBN38 carbs....I have no intention of going crazy porting a fan cooled engine as cooling would become a issue. Just trying this to get a little "cleaner" response from the e...

It's been awhile since I've done any mods to a deere since the 4/6 into a new breed LF. I've been into hot rodding jetskis and have a new project in mind as the Kawasaki engines of the time have many similarities. One of these is the intake port shape and bolt pattern, and the 440/550 jetski manifol...

I would consider this sled to be "investment grade" if it's as described. This means if detailed and properly stored away for another 10-20 years the return would be greater than the investment. Of course, this is what you tell the wife. The reality is you have something truly special to d...

Pics please!!! Checking into shipping from Oregon, but awaiting pics to make offer or get serious into buying this. I lost my LF's in a one sided court battle with an ex girlfriend and looking at getting back into JD sleds. Thanks!

LOL, looks like I learned something too!!!

Couple differences in pistons. Primarily the ring locating pin is moved to a different location. Also, the rings were a little thicker than the standard Invader. (Invader part number 13008-3001, 4/6 13008-3008) As mentioned by Rainville, the 4/6 pistons were coated as they are prone to cold seizure....

The 4/6 engine was unique only in it's port design and multi plug ignition. However, if you run a "deere" bottom end, your initial timing should be set at 22 degrees, well beyond the deere initial settings. The dual plug ignition is not necessary, however I recommend getting a set of Invad...

Howdy Matt, site looks great!! Much easier than the last time we transitioned to new site, and I didn't lose any seniority!!

I know!!! I have an old Indy that needs skis and the bolts are stuck in the bushings....I am going to get to it this weekend as I've pounded, heated PB Blasted em all without any luck without damaging the bushings. Now I'm looking forward to it and will post some pics if it works!

Hey guys, I was just reading up on sleds and such and came across this handy little technique. It involves using melted wax on rusted (or corroded) bolts or anything else that is stuck. I've been wrenching forever and have never heard anything like this. Everyone on this guys thread swears by it, an...

Eric, you're Killing me!!! Wait a few months and my court crap will finally come to an end. I have a few sets but still in my ex's garage. Will PM you once this FINALLY ends!!! Any improvements on the SF? (I have an idea that this is the sled in need of NOS springs!!) Anyways, wish me luck, and any ...
