The zong is in fact smoother, the hawk clearly has more low end grunt. both appear to be good motors. One thing, the zong clutch is VERY smooth and 2 finger light. The Hawks is stiffer. Zong tranny seems free'er running so far, Hawk's feels just plain industrial:) which for me is a good thing. Zong is happier in the high revs/ Hawk in the low/mids, like a tractor-think smaller KLr like.
You are going to change the same things to get either ready for adv work, the Hawk just saves you more money.

I'll be curious to see how the Zong responds to you, as compared the the Hawk, after break-in. These CG motors change dramatically between 300-500 miles in their power delivery. Mrs 2LZ TT noticeably grew in mid-range between those miles.
I'm sure spinning the counterbanancer takes away a little umph but with these tiny motors, who knows how little.

It's neat that you have both bikes to compare and I look forward to the reports as they go along. I don't have a Hawk to compare to but you're sure right when you say how solid of a feel the TT has when you're riding it. For a little bike, it has a very substantial, stable feel to it under you.

Interesting that you have both perspectives, but I am thinking of someone flying in to the US and getting an assembled bike delivered to them from CSC vs. the hit or miss of putting a Hawk together. I guess, if one found one at a dealership, assembled, that could change the dynamics. Motobuys in Phoenix sell the Hawk, so I wonder if they would assemble them and PDI if one was to visit their retail store? There is another dealer selling Bashan Storms in the Phoenix area.

As far as going with Wolftrax, I had emailed him months ago, and was discussing riding down to Cabo and back, whereas he would continue on his journey by hopping on the ferry.

I am actually thinking of getting my old TMEC back in shape, but Excalibur has one for a super low price. They took it back under warranty a couple years ago, but have since fixed it, but it has been sitting for at least 2 years. They are in the middle of moving warehouses, so I would have to go this week, as they don't want to move it, but that would involve renting a truck and driving the 600 miles there and back.

again, culcune, sorry in advance but a couple of things about the csc assembly...
mine was assembled and road-tested by csc, before recrating as were all the units delivered so far. This thread has numerous reports that this has not guaranteed problem free bikes, nor does it mitigate the things that would still have to be done to prepare one for your own expedition. in fact verses my own Hawks, one put together in front of me by a knowledgeable
seller, and one done by myself and my bro, we have had fewer issues with the Hawks, save the recent discovery of the stupid mechanical axle bolt swingarm spacer mechanism- which MAY well be the same setup used in the TT250 swingarm, we haven't torn that one down yet.
In any even, the mods and prep needed to be done look to be the same, not counting the shock/headset/speedo problems I've found on my tt250, but NOT on the hawks....
ps, that TMEC was(/remains?) a good piece of kit:)

Hawk engine and TT 250 engine. The Chinese make me confused and I did drink the punch tonight.

Nice posts on the sites. Good to see these replacement motors are pretty cheap. I believe that overhead cam unit produces a little more hp than the pushrod. :tup:

Do you think the OHC mill will fit the TT250 frame?

TT250 Trail Ride
 
Rode an excellent trail ride yesterday courtesy of Glenn Morgan (MrGem) on the TT250.

As I'm not particularly skilled, I give it a 7 out of 10 for difficulty. Some pretty steep and rocky climbs and descents. Half-way through the ride I realized it was forward or nothing as going back was not an option. Quite sore this morning, but glad that I rode outside my comfort zone and survived.

I'm Pleased so far with the TT250's suspension for my uses, but I could tell that the suspension would probably be inadequate at higher speeds on this particular set of trails. I think the TT250 isn't designed for this type of riding, but it did it OK.

this is the question. one would have to have the schematics for the motor for dimensions. first thought is no because of the possible addition to the top of the cylinder due to the overhead cam mech. unless there is plenty of room on the 250tt between the frame and the head. i wouldn't know that, i have a bashan.

I think that Fastdoc could have fit either pushrod or OHC motor in his XR200 he built. Hopefully he'll chime in....

Oh, Man I love it up there. See any good burns / flames? You rode right though where the fire was a few weeks ago didn't you?

DanKearney 07-25-2016 01:57 PM

The fire was north and east of Nederland. Nothing but trees and grass where we were riding.

Cheers,

dan k...any trail that says "nat forest boundary ridgeline" has to be some serious stuff. thanks for sharing. what kind of technology did you use to track this trek?

Ghaniba 07-25-2016 02:23 PM

It's just the GPX track from my Garmin Oregon GPS unit. I imported it into Google maps.

I calculated the elevation profile for the ride:

Dan,
I would agree on the suspension. Not enough travel for some of the rockier spots. I've not looked at adjusting the suspension much but might look at the preload and rebound on the rear shock and rebound on the front to see if it helps.

Will be looking at gearing too for steeper trails.

Do you still have your TT at the stock jetting?
