    Mixing 16gm and 14gm weights in a Hunterworks sheave?

    Are there any issues combining 16 and 14 gram weights in the sheave.
    I’ve got some very heavy 27” tires and when riding in the WV mountain roads in high going up slight inclines the machine won’t generate enough torque to get going much over 30-35 mph, once on flat roads it does fine and get up to around 50mph.
    I am just thinking if I can increase the rpm’s a bit I think it may be fine.
    Anyone done this before?

    So long as you put a 16 and a 14 gram in each pair of slots on the 700 cc engines, you can do it. Also make sure the 16 and 14 are opposite each other on the other side of the sheave so:




    ..............................................16g| 14g............................................... ...
    .........................................14g ...........16g.................................... .........
    .........................................16g ...........14g.................................... ........
    ..............................................14g| 16g............................................... ....

    I thought there was an issue with the heavier weights trying to move out faster and taking all the load.

    If you don't have them staggered as suggested above and you had a big spread between the weights, say trying to combine 14 gram weights with 20 gram weights, I can see it being a problem. For example:

    ..............................................20g| 20g............................................
    .........................................14g ...........14g.................................... ...
    .........................................14g ...........14g.................................... ...
    ..............................................20g| 20g............................................

    Would be bad

    I have never been a fan of mixing weights for this reason and you will not see a difference in 14 and 15 equal and 16 and 15 equal. You see a difference in 14 and 16.

    Well gentlemen, the ride and 15 gm weights did great. Did around 55 miles in the WV mountains, it was acting as if it was new again.
    Then.....going up a black top road to the next trail and BAMM... NO power..engine would crank over but not start?
    You could hear the fuel pump come on and seemingly pressure up. But, no start.
    Checked fuses, oil level, coolant good...
    Would love to hear others thoughts.

    Fuel injections? Coil?
    I just got it home and had to tow it up the driveway with the grizzly (old faithful to the rescue).
    Any help in diagnosing the problem would be greatly appreciated..

    You'll do better with a new thread.

    Any codes? You need fuel, spark and compression. Which one don't you have?
