I'm getting some money together for my winter build and looking for a good motor to use.... I wanted something with more power than my little china girl SR, but I also want to maintain the use of a lever actuated clutch. Looked for a while found nothing. Does anyone in here have any ideas?

Perhaps any engine, and fit a countershaft with a clutch on it, like a speedway bike? Sample pic of an expensive one here, you will probably find something cheaper if you hunt round: http://www.foxyraceproducts.co.uk/NEBClutch.php

if you have a large frame you can use a lifan or loncin engine they start at 50cc and go all the way to 150cc+

try a 79cc hf predator. you can make a manual clutch by using a belt primary drive and a cable controlled idler pulley. check out my build: http://motorbicycling.com/showthread.php?t=40292

HFT has a 6-1/2HP for $99.99 until Dec. 1 I think. It is light and sloper 4 cycle OHV. so has low profile and is light. I have one on my 3 speed Monarch and it runs about 50 mph with balls of torque

lifan 98cc is very low profile, looks better than any other clone engine, and has decent power. it is much lower than ohv engines like harbor freight and cheaper than a briggs. the compression can be raised from 5:1 to 9:1 by milling the head and that will give you a huge boost in torque, it should cost less than $30 at a machine shop.
