Rather high rpm before it moves  By  richardhill (Read 1,123 times)

The clutch seems to engage properly, it is just that I have to give it a rather high RPM before it engages sitting still. At normal riding speed it works fine Also riding at speed it boges down if I try to accelerate up a hill, I think this is a carburetor fuel adjustment, issue, and will wait untill I get a few miles on it. . I had an Ice Bear 300cc Magnum 3 years ago and I loved it, put over 3,000 miles on it in two years, but because of some surgeries one after the other I had to sell it,

I have put 300 klm on the 2018 PST150-9 at 13/14 throttle if I start up a small or slight uphill grade it bogs down. I have noticed there is no air speed adjustment, only a brass plug where it should be, so there is no help there. It idles fine at 1800 RPM. I plan to put a big bore kit in it this winter. I have to find out how large I can go before I have the case bored out. I found a 170 cc that states no boring required. I am going to replace all air and fuel hoses and spark plug. Any suggestions greatly appreciated. PS I was riding a 2012 300 Magnum for three years had 5000 miles on it but had to sell it because of medical issues. I am on the mend now.

You can fiddle with the idle mixture screw (the one behind that brass plug), til the cows come home, and it won't help your hill climbing ability a bit.

Do you think that maybe you are expecting a little too much from your trike? It will never perform like the one you used to have, with twice as much engine.
