I think I can source cylinders, pistons and heads for a 440. Not sure about the carbs and intake though.

Sorry I confused myself...LOL.

I would keep it 340 you won't have to recalibrate the clutch either.

Is it worth doing, or should I keep it original? What top speed can I expect from a fresh 340? Depending upon your weight it will be up to 15 mph slower and have less balls off the line. 340 parts might be easier to come by than 440 engine parts but could be more costly overall as you have to acqui...

Hi all, new to the site I recently aquired a 76 trail twister with low compression on the pto side (95 lbs). A little scuffing on the piston sides and some flaking of the cylinder. I'd like to know if the bottom half (cases and crank shaft) are the same for both the 340 and 440. I believe the strok...

If it is original equipment and/or using the original jackshaft it is a slide on fit with a long square key. Put the penetrating oil to it and let it sit. You can also use heat (I use a bernzomatic for plumbing as you don't really want more than that). Then get a 4 foot 2x4 and give it a couple of s...

I would be interested in a set of mounts.

Nice fairing around the light. What is that off of.

2 issues with the 1035. It can be found considerably cheaper elsewhere and The MAX1035 is the closest size that Dayco makes to the Merc belt. Is is not an exact clone and has a tendency to slip as it is a little bit bigger than the Merc. Make sure you adjust the chaincase concentric after installing...

There are no Liquid Sno-Twister manuals on that site.

And Mike...If you are going to shamelessly promote your site at least let everyone know what you are doing. LOL!

The 250RLC cylinders will bolt to the K4402AS base. While it will fit and work the parts are not identical.

Hello I am very new to merc sleds and this forum. I found a 74 sno twister 340, the guy may want to trade my 83 jd LF for it. My concern is there is no information on this sled anywhere was there a 340 in 74, how hard are parts to find. Thanks sled There was no 1974 model year 340 Sno-Twister....Ho...

All ignition parts interchange on all liquid Twister sleds.

The 1974 and 1975 SR belly pans are different. Major differences.

I am in the process of cleaning up the bone yard and have started to part out 4 scoots. I have many parts available. What is not available is carbs, tracks, skis, and running motors. I do have a couple of stuck engines that I can get parts off of. PM me your needs. Parts are in New Hampshire. Will s...

Originally it had the K340RLC
