Turning Wrenches / Re: Wiring Question

Last post by Joe6v6 - Today at 06:55:42 PM

volt meter @ battery terminals. shouldn't really go over 14v , and should see over 12.5-13.00 at 1500-2000 rpm.

Thanks for the info, Even though this bike will have almost the bare minimum of wiring its still quite a challenge. Especially to make it look nice.   .

(not mine)
Really nice looking pair of low-mile 125s! A few really minor issues but easily fixed (missing badge on left engine cover, missing mirrors, oil leak (oil pump?).

Turning Wrenches / Re: Help with my left cylinder

this may be way out of left field, but have you thoroughly inspected your autolube lines from pump to inlet on carbs? All the extra oil in Left side sounds like it's getting more oil delivered than right side- maybe someone swapped a larger diameter replacement hose on that side at 1 time? Maybe something in the pump itself? Alternately or concurrently could pilot circuit air intake be blocked on that carb from bell mouth but not obvious on visual inspection?

so yes, it needs a switched 12v source to the brown wire

Thanks - just wanted conformation.   .   

On another note - Is there a simple way of determining that the charging system is operating correctly? after the motor is running of course.   .    Joe

I have changed the intakes and have adjusted and readjusted the carbs all kinds of ways. Does anyone know what the typical temp range of the cylinders should be? Although the temps are different between the cylinders, their temps are very consistent. It will be a few days before I can get back to working on the bike, but I want to swap that left carb and see if that has an effect. I appreciate all the tips and suggestions. Thanks!

This guy cut a Daytona head perfectly in half for me - for free! So talented and generous. Never actually spoke to him, communication was all by email. This makes me sad.
