Still going through this new to me bike to figure out what all has been done to it!


Previous owner claimed:

13oz Flywheel Weight = No Dice

Eric Gorr Big Bore kit = Flanged head gaskets appear correct still don't know which kit it is.

Rekluse Z-Start Pro = After some adjustment this is working nicely

Oversized Gas Tank = From what I can tell it is an IMS needs new cap


So Far I have done:

Adjusted rekluse

new orings and springs on expansion chamber

new clutch cover (stock was cracked due to overtightening)

new twin air filter

bled the brakes (fluid was toasted)

new Kenda Equilibrium rear

New grippy seat cover

replaced some missing or incorrect fasteners with oem

I use this bike for woods riding. This is the first bike I ever bought, and I was told it was used as a spare bike that didn't get ridden very much. I think he wasn't being truthful lol it rode great at first, brought a buddy that has ridden most of his life to check it out and it was in really great shape for the year. Spring of 2016 I put 30+ hours on it and did a lot of upgrades in between. I learned a lot about jetting, and worked really hard getting it all dialed in for peak performance. Ended up tearing the top end apart because I heard some noise that made me concerned. Found crank bearings were worn, con rod bearing had really bad side to side play, piston didn't look too bad but still wanted to replace, luckily cylinder was in good shape. I did a complete top and bottom rebuild with OEM parts. Kinda expensive but $800-$900 later-a lot of time, patience, and cleaning-and I have basically a new engine and all the tools to rebuild one again. Rebuilt carb, repacked silencer, new chain and sprockets, all at the same time. Around 12 hours since rebuild and it's running very strong, great power, and so much fun to ride. Still have a little carb work to do, need to go up a size or two on the pilot jet. Overall though the bike is a blast, people told me it was too much to start with but honestly I think it was perfect to start with, I'm certainly not a greatly skilled rider but it taught me a lot, and it made me progress a lot and quickly.

I bought this bike completely clapped out from a coworker as a winter project. Rebuilt the engine and transmission. Rebuilt and resprung the suspension. Have been riding single track, groomed trails, and some motocross. Loving this bike.
