    Yamaha 760 Engine help

    Awesome! Thanks - the 94 raider donor had it. Maybe it was a Yamaha service cylinder after they started cracking.

    Dual 38 mikuni carbs

    There is a real nice set of real 38sbn’s on Facebook market place for $125. These are dual pump normal SBN’s. Perform little better than OEM yamaha. To run on the oem intake you would need oem adapters or buy a Rhas plate for the oem manifold.

    Yamaha 760 Engine help

    Show a picture. I’ve seen 200+ 62t cylinders and never seen one without the rib. All 701 62t’s have the heavy exhaust even the rentals in the resort countries that have unique parts

    Yamaha 760 Engine help

    62t castings are either 701 cc 81mm bore with groove in the bottom exposed portion of the sleeve or 760cc 84mm bore with no groove in bottom exposed portion of the sleeve. Both castings have reinforcement ribs running on the outside of the cylinders on the intake side (for the heavier exhaust)...

    Dry Pipe Solid Mounting

    You will crack your speedwerx! Harmonics will eventually crack it anyways. Best to always have perfect alignment and all 3 lord mounts in good condition. Never force then to accept the bolts. Do not install in a bind.

    Unequal cylinder temps on tpe 964

    I was told in 1997 or 1998 or around that time, when I complained to MSD, that it was so the rear cylinder (if wired properly) would be retarded from the front. Few people commented back in late 90’s/early 2000’s on rec.sport.jetki before forums. Very few people in the Freeride community...

    Unequal cylinder temps on tpe 964

    Traditional msd dual channel billet plates do NOT have the pickup triggers 180 apart. Depending how you are wired either the front or rear cylinder has advanced timing relative to the other. I recall I measured the difference and it was 2-3 degrees different. 2 seems to stick more than 3. The...

    Flywheel balancing?

    Here is another one to think about. Impellors - they are all balanced. Even Skat and Impros balance the props once repairing or repitching.
