Hawk break in

Rail32 · 03-02-2017, 08:43 PM

Wanna rejet carb ASAP. But know its senseless unless it's broke in. So I have 100 miles mostly 25 mph Max . So figuring 4-5 hours total. Maybe completely warmed up to operating temps ,,,12 times . I am thinking I am good to go . What do the rest of ya think ?
Maybe not senseless as much as a waste of time , after a bit more thought.

If you are asking me how I broke in my counterbalanced Lifan engine, I would tell you that I put 500 miles on mine before I started pushing up the rpms . I'm a conservative kinda guy.

they say its best to break one in with it jetted rich and the hawks come jetted extremely lean.

"They "

They always seem to get me into trouble , same as them .
Anyways here is what I know . Fuel is a detergent , cleaner , or simply will break down oil . So my thinking is rich fuel carb washes away oil easier from piston and cylinder . I have read this rich theroy many years ago when I was building engines when when I was a kid . Never really bought into it . I do agree to never wind out a new motor anything more than a brief moment . I also agree with never holding that one rpm steady ( aka cruising down a flat road for a long time) . I very well feel the carb Is super lean and it needs to be tuned ASAP. I have time off work today , I may just do it , and again if needed . Waiting for pipe anyways , but I can mod air intake prior anyways . It's a simple easy carb for removing and tuning . Thanks for all replies .

I wouldn't hold back on re-jetting. Just take it easy for the 1st 500 miles. You can feel when these engine start to loosen up, smooth out and come to life.

yeah, I jetted mine early on as well. it doesn't seem to have hurt it any. I also ran up the RPMs occasionally, but did not hold it for long. Generally, I didn't go over 40 for any long period of time.

If you want to rejet, go ahead and rejet. I think this idea of waiting for the motor to break in was with regard to tuning. My hawk ran so crappy out of the box it really needed rejetting almost immediately.

It's a CG engine, don't overanalyze it, don't abuse it. I think your'e 25 mph max is overly friendly.

What's the stock size jet?

Agree, I can't think of a single benefit to running an engine lean, unless you are after fuel economy. Even then, at what price to the health of the engine?

How's that saying go?

I went a bit crazy. Not only did I slap in a 115 jet right away and adjust air mix screw. I threw On a Uni filter , modded or gutted air box , whacked off spark arrestor, and now just waiting for pipe to get here . Wow did this all really wake up my little China girl . Oh installed NGK plug while I was at it . I am a bit too rich right now , but woth pipe it should be almost perfect . Besides test ride at 27 degrees and 3 " snow on ground made for a intersting ride . The snow was flying pretty good to see where I need a bit more protection around Uni filter . Will do that tomorrow . Now if only the pipe would get here

For some unknown reason I can only load one pix per post . Hope this helps . If you want more , pm me your email and I will give ya lots more . Maybe you can post them here for me than . Or anybody else also , it's cool .

The easiest way is to set up a "photobucket" account, which lets you kid pics up and hosts them for you. I have the app on my phone. Take a pic with my phone, open the app, add it to my Photobucket account, copy the image URL and just post it here. You. An put up as many as you want. And it saves the pics for you, so if you want, you can delete them off your phone to clear up space.
