Some Hawk upgrades

[OneLeggedRider]

Been busy today. My new folding shifter, my new 520 chain and sprocket conversion, and my new performance exhaust pipe. It's a bit louder now lol. 😁

Installed the bark busters too, but they're absolute crap.

Mods make me happy, even when it's other peoples

[roundhouse]

The exhaust is my fav mod. makes the bike sound GREAT!

Congrats

Here's the junk brush guards. Had to chase the threads on the outer mounting blocks before installing them. Then the right side went on no problem, but the left side split as soon as I put any torque on it. I patched it with epoxy for now and it will work, but I'm getting a better quality set when I get my fat bars.

My first set I ordered were the same crappy casting and left hand side was already broke so they sent me a replacement. Although they looked the same the casting was 100% better. Someone else had the same thing happen to them. I guess they are trying to dump the crappy ones 1st and if someone complains then the send out the good ones.

Well ya get what you pay for. I found a nice set for $60 and those with fat bars ought to give me some piece of mind when I lay it over at low speed, atleast protect the hand controls.

POTENTIALLY EMBARASSING NOOB QUESTION ALERT


Ok, now that we got that out of the way, some set up. I've read that the Hawk/TT250 share a similar (or the same?) engine. Is that true? If so, I'm also pretty sure the TT250/SG250 are the same engine as well, which would mean that the Hawk/SG250 have either essentially or exactly the same engine.


If all of the above is accurate, would that pipe work on an SG250? It looks great and I think it would make an excellent addition to an SG250 Scrambler build. If it would work, where can it be found?

Yea Jerry it was me with the hand guards. My first set looked like cast aluminum and i broke one trying to adjust it. My second set looks like proper smooth finish aluminum and went on no problem . They have since been tested in a slow fall over crash in the soft ground and they did save the clutch lever so that is what they are for.

They are not the same engine, the TT is counterbalanced, but the pipe will fit on both if you modify the exhaust flange bolt holes. I don't know about your particular bike.

[Megadan]

The head pipe would definitely bolt on. If the mid pipe and muffler would work is a different question, and I would be inclined to say that there may be a bit of modification required to make it fit and work correctly. In large part due to the fact that the SG250 has twin shocks, and the muffler would be trying to occupy the same space as the right hand shock.

An exhaust that will likely fit a lot better would be the scrambler exhaust Cleveland Cyclewerks sells for their ACE, which is a similar style bike to the SG250. https://clevelandspeedshop.com/colle...ambler-exhaust

Spent some more on the Hawk. Got heavy duty tubes for it. It was running way too lean after putting on the performance exhaust pipe so I took the mixture screw from 1.5 to 2.25 turns out and swapped the 110 main jet for a 115.

It's starting, idling and running better now but I think it's still a little lean and I haven't opened up the airbox yet. So I bought .45mm drill bits for the pilot jet. If I'm not happy with that I'm just gonna get a better carb.

Also got another helmet and am shopping for a mesh motorcycle jacket for summer riding.

The bark busters work great from Australia too, but they are pretty pricey.

I lost my chainguard and left passenger footpeg on my way to Canadian border last year

[Megadan]

My engine idles nice and stable with the original 40 pilot with my ported head and it is less than 2 turns out. Maybe consider cleaning that carb and blowing through the passages. Might have something stuck in there blocking flow.
