    But again I am so happy with turnout especially for most of all parts and pieces on this bike were free or just sitting in tubs or boxes in garage! For that matter this 86 TRX was free I just paid to have registered. But if I needed a part I sold something I had laying around and used part sold money to buy what was needed.
    I may have $350 in this bike maybe a bit more.
    Again I’m just shocked 40 HP on a 2nd bore cylinder no porting, VForce3 reeds, FMF SST pipe, 86 CR 500 carb, and a OEM 1985 Honda ATC headgasket.
    Thanks everyone for chiming in on my project
    Congratulations on a nice OEM setup....!

    Don't be shocked Mike, OEM cylinders make awesome power and are the most reliable to date. When porting, matched setups even as a Duner, MX, TT or Woods....68MM x 72MM OEM's can hit 57HP/40TrQ. In some cases considerably higher than 310's or 292's. Check out the BDT 68MM x 72MM link and Dyno Graph for a MX engine...better than 99% of 310's...

    Were these #'s at wheel or engine......? See they give out around 8k. Pretty good for stock. Imagine hoping my ported goes to 10-11k, upwards of 55-60. HI RPM Port, head configuration on 108 cam2. Check out Richards' Engine Development. Maines hidden gem, IMO.
    Did my 99 583cc ski-doo. Torque monster, 80 trq-112hp at 7800 +/- tach being off. Sock 670's had 80 tq, so I was happy.

    Like to see more dyno runs.
    86 253cc, 40pwk, CT OOF pipe.
    99 583 Formula Z
    74 340 TnT- in progress/restoration
    Owner, hellabrokeNH- coming soon.
