Hawk top speed - Page 2

did you change the rear also? Does it sound like it bogging or are thr RPM up there?

w0ss · 05-25-2016, 07:50 AM

only did the front sprocket. It is weird in low gears it seems that the revs go up but at a certain RPM power just dies. But after like 3rd it really just bogs down. I only have like 20 miles on the bike

You should be able to do at least 60mph. I'm 6ft 250lbs and I can do 60mph on the flat. Did you replace the spark plug? Have you replaced the piece of crap stock carb, or at least rejetted it?

I replaced the plug and have a mikuni carb on order. I haven't rejetted the stock carb.

could be that the choke is faulty and doesn t open? or excessively tight valves, not uncommon on honda clones, did you check them?

w0ss, something definitely not right there. I'm not sure how a stock Hawk runs but others are saying better than that. Is your clutch slipping? Do you have any play in the cable?

I live in Mooresville North Carolina. How can I NOT be?!

It feels like it bogs down after half throttle on the road. Does that help?

Also pro tip If you plug the bottom line out of the carb to the petcock your carb will spring a leak...

exactly the same as mine was doing. it's the jetting. way too lean on the main jet. the new carb/jets will fix it up. don't sweat it. Most of us start off with a 30/115 combination with the pilot jet at 1.5 turns out. I went to a 117.5 with no improvement in performance. I'm running just a bit rich though. I am going to try to go down one step from the 30 and back to the 115 and see how it does. However, the 30/115 should work well enough for you.

The bike will run much better with the proper carb / jetting. Mine was a slow dog prior to installing the mikuni carb. Check your valve clearances as well, mine were very tight and the bike starts and runs better with the valves adjusted...

w0ss · 05-25-2016, 05:15 PM

I did do the valve adjustment. it's funny I bought from a CA seller assuming it would come quicker. Looks like it is going to be next Friday and it shipped on Monday. How is it that I get stuff from China in a week but CA is 2 weeks. I hate smartpost.

I'm willing to bet that its your choke lever!! It could be all the way closed, ioen or at hale point. Thus happened to me yesterday..I was riding half choke and I was all good u til I tried to go high speeds my bike would bog. Just mess with your choke lever. Hope this helped!

When I took off the carb I looked at the choke. The valve in the carb moves with the Choke level. It didn't look like it did anything but restrict air but I assume that is the point of the choke.

I took pictures of the plug and going to try to get get them online somehow. I am at work so need to figure out a way.

I did notice that sometimes it seems to sputter at higher RPM's as well. I am debating slotting the tamper proof screws on the original carb and playing around with the setup on it. But not sure I want to bother.

Rather than swapping out MotoCheez cracked his open and has had fantastic results. - Really what do you have to loose?

Plug looks super lean to me.

The screw on the carb body only affects idle mixture.

w0ss · 05-26-2016, 03:52 PM

without new jets any way I can make the mix richer with the stock carb?
