What ranges should one have to work on the clone engines. I assume one in foot pounds and one in inch pounds.
 
For the average DIY'er go to Harbor Freight and get 1/4'' drive in.lb. and a 3/8" drive ft. lb. on sale for $9.99 that's all you will ever need;And when your there look for that 60363 that may be hiding in the pile.
200 in.lbs. 80 ft.lbs.
 
Would you all say this is a good general start to a torque spec list? I found it on the interwebs googlemabob thingy...

For Honda and Honda Clone gx160 (5.5 hp) and gx200 (6.5 hp) Engines
This is the size list so far of the bolts and some torque values. Please let me know if you have anything to add. Please note these are the stock sizes and torque specs, please when installing aftermarket parts consult the Manufacture for proper bolt size and torque specs.

Bolt /size /(torque foot/lbs)

Connecting rod bolt M7 x 1.0 (9 ft/lbs)

Cylinder head bolt M8 x 1.25 (17 ft/lbs)

Flywheel nut (special nut) M14 x 1.5 (54 ft/lbs)

Rocker arm pivot lock nut (special nut) M6 x 0.5 (7 ft/lbs)

Rocker arm pivot bolt M8 x 1.25 (17 ft/lbs)

Crankcase cover bolt M8 x 1.25 (17 ft/lbs)

Muffler mounting nuts M8 x 1.25 (17 ft/lbs)

Cylinder head intake bolts. M6 x 20 1.00 (17 ft/lbs)

Cylinder head exhaust bolts. M8 x 25 1.25 (17 ft/lbs)

Crank Shaft bolt. 5/16"-24 x 3/4" fine thread (30 ft/lbs)

Crank case mounting bolts 5/16"-24 x 3/4" (17 ft/lbs) (some engines use M8 x 20 1.25 pitch) (17 ft/lbs)
 
Be careful;- With 17 ft.lbs.on the 8mm- head bolts and side-cover bolts; stock bolts w/lubed threads, bolts may break on headbolts, and cut gasket on side-cover; and that M6 on intake will break bolt also; 30ft.lbs.on 5/16"x24 tpi crank bolt is way too tight;flywheel 85 ft. lbs. dry; If possible use NR or Raceseng stud kit on Head& side-cover Well worth the investment stock bolts are Junk !!!!!! IMHO.... NO-- 17 ft. lbs. on M6 Bolts-- Wrong Spec.
