I'm pretty sure this 1987 110 has been warmed up a little from the performance it's giving but my question is what do I need to really bump the horsepower up to as close to the 140 as I can get ?

In particular, what series carbs and reeds do I need, and what about cylinder porting work ?

If the port work is a must have to make a difference then I'll wait until the motor needs freshening up and do it all then.

Some say the ports are the same and others say the opposite on these bubble back 90 degree motors ... so I don't know what to think but it seems logical that the 140 would have larger ports ... but, maybe not :confused:

Thanks
