Hawk is here, yay!

I thought it was just my shifter, or maybe I just got the wrong shifter. I guess RPS must have extended it. On a good note, the new shifter does have the folding peg!

The IMS shifter is just a hair longer, its for an xr400, but the peg also sits a bit more inward as well, and it gives me just a bit more room for my big foot.

It's Alive! Before you say something, yes, I have it idling at about 2100rpm. I did that intentionally for it's first break in run. Idle is now adjusted properly :P


As mentioned in the video, the valves need adjusted again. Clutch REALLY needs adjusted. I thought I had it right after pulling the cable to lube it, but obviously I didn't. Ah well.

Carb setup is just about spot on. Fired right up dead cold with half choke, and I was able to open the choke within 30 seconds of firing. 1 1/2 turns on the mixture screw. It will need a bit of tinkering, but not much, I am happy.

Your idle is too high, its obvious you don't know what your doing and you have no business working on a motorcycle

Dangit! Guess I better sell them both!

Changed the oil, adjusted the valves to .004 intake .005 exhaust. I started at the recommended TT250 specs for break in .007, but it just didn't want to run right and was WAY too clattery. the .004/.005 combo is still classic flat tappet loud, but its the right kind of noise now.

I backed off the idle mixture screw half a turn as well, so now it is at 1 turn out. Plug was rather sooty for the brief 20 minutes I first ran it. Not overly sooty, but definitely on the rich side for sure. Still hangs just a teeny bit before going back to idle so I may back it off another quarter turn and see how it behaves. That aluminum thumb screw for the idle mixture is a lovely thing, I must say.

Took it for it's maiden voyage around the neighborhood and up a major street here for a total of 5 miles, doing the typical break in thing, up shifting and down shifting constantly, engine braking, throttling up. I wouldn't call what I am doing a hard break in, but not really gentle either.

That said, she gets up and scoots. I was expecting the bike to be rather doggish being brand new with 17/45 gearing out of the box, but it pulls my 260lbs of chewed bubblegum rather well. Surprisingly comfortable too. I gave the suspension a mild test and it performed way better than I was expecting. Overall, I must say I rather love my Hawk. I don't regret my decision to buy it one bit.

Please tell us more about that! Where did you find an aluminum thumb screw for the pilot mixture screw?

So, after logging some actual miles and getting the bike nice and hot and playing with some settings. 1 turn out was a touch too lean for the mixture screw. I have a feeling the 30 pilot on a stock bike is probably a touch too big, so it is going to make getting it dialed in a bit tricky. Now at 1 1/4 turns out and it improved some.

The 110 main jet is a touch on the rich side. after checking the plug, but only JUST a little. I am going to try and move the needle clip up 1 spot/needle further down and see how that goes. If it is still a bit rich, I will go back to the middle position and try a 105 main.

Current max speed reached is 50mph... only because the speed limit is 45 on the road I went down and well... it's not registered yet because I still await the almighty MCO.

That said, it got up to 50 pretty quickly and was pulling strong. I did end up ordering a 43 tooth rear sprocket. I want just a bit more leg room in the gears than what it has now, but not much more. I am going to take out 2 links when I install that new sprocket for a 128 links total, along with 4 Honda SL350 sprocket/cush drive studs also on the way.

Also of note, the factory shifter is now installed on the bike. With the sprocket cover bolted on, the top bolt position of the IMS shifter means the bolt can't be installed. You can install it and then the cover, but then you can't get the bottom cover bolt in because the shifter is in the way. I need to figure out some formula to make this work, as the stock shifter sits too far out for my liking, and well I bought the IMS so I would like to use it.

It is taking every ounce of my willpower to not install the exhaust and do the airbox mod/filter. My "more" complex doesn't like stock. I do it for the sake of the dyno though... That is my chant.

EDIT. Random side observation on the 2017's, at least mine. No turn signal beeper/buzzer. Maybe mine is just broken, but my signals work, so it came broken in the right way.

Hey megadan my solution for the shifter was to cut the end off it and weld it to the MSR shifter. Took longer to set up and clean up then to weld and install. Just an option to consider.

[Megadan]

I thought about options like that, but I like finding simple solutions to issues that your average young person might be able to accomplish. I am going to try a couple of very simple approaches first, such as replace the flange head bolt with a standard bolt and washer, or quite possibly a button or cap head allen bolt. Without the flange on the bolt it may buy just enough room to finagle it in.

EDIT: I went ahead and ordered an EMGO aluminum shifter as well (Heck, it was only 19 bucks) which has the bolt on the bottom. I can compare the two, and in the end I will probably just turn around and sell the IMS shifter to somebody at an obvious discount.

Yes, it is my lazy way of doing things lol. I didn't order it to begin with, it was just sent to me when the actal shifter I did order was out of stock.

Thanks! May we see a pic of it installed?

[Megadan]

Of course. Will have to wait until I get off of work, but i will definitely snap a pic.

Awww heck. You need a break.

What is this "break" you speak of?

Anyway, as requested...

With mine, I ended up using the spring that was on the original mixture screw combined with a small washer under it to get the spacing to match. It may be able to be run the way it comes, but I figured I would stick with known variables. A note on said small washers... the one that it comes with, at least on mine, would not work because the center hole was not centered. I ended up having to use my jewlers files to oblong the hole so it would work.

[Weldangrind]

Thank you very kindly! I just ordered two.
