Ehh.. just start with a better motor, be cheaper and easier in the long run. Spend some time aboard a DRZ, not your cup of tea but twice the bike and stupid wheelies on demand. 6 months ago I found a clapped out one for $1400, could've dropped another 1000 in it and had a mean a## dualsport. Still kicking myself for not jumping on that one.

There is a reason my youtube name is oddballperformance. I am not the type to get a better motor. I am that weirdo that loves to make a better motor out of an inferior one.

I earned the nickname because of my strange obsession with Isuzu Impulse JR chassis. The old rwd door wedge cars with their 2 valve hemi headed 4 cylinder turbo motors. 2.6 swaps out of trucks with custom cam regrinds and custom forged internals with fairly large turbos making silly amounts of torque and decent hp.

You should have seen the laundry list of parts adopted from other vehicles lol. Fiero spindles and hubs with corvette rotors drilled to 5x100 and corvette calipers. Just as an example.

I understand that, and I was referring to getting a Loncin OHC 250cc motor for your Hawk.

But honestly you could get a used DRZ with twice the power (if not more) that could be jumped without fear of bending a rim, and be stupid reliable for $2500 to 3000 because they been making them for 18yrs with almost no changes (testament to quality). And with your ability and talent you could turn that bike into a fire breathing widow maker I'm quite sure.

I mainly want the 6spd transmission far more than the OHC setup lol.

I have ridden a DRZ or two. The 400 to be specific. I did like it very much, but it isn't quite my cup of tea.

No sir, if I am going to spend silly levels of cash on a Japanese dirt bike/dual sport of any kind, I am going to have to go straight to my childhood bedroom wall poster (the one that was next to the Ferrari Daytona and Lamborghini Countach posters) which is the XR650R;

Yes, that's right. I am a BRP fan. Just so damned hard to find locally.

My high performance instructor Don was a wirery little fella in his 60s that had worked as tuning specialist/Tech for several teams in the NHRA for most of his career. He had a very short fuse and even lit into me (his prize student) a few times.

But he owned your dream bike, and was always tinkering with it and throwing it on the dyno in between classes. Mind you this was his daily driver but it had a lope at idle that was a dead giveaway of it's capabilities. The school was located in a developing industrial park and sometimes on our lunch break he would show us what his big thumper could do. A bit big and top heavy for my taste, but it was a serious beast.

Megadan · 10-26-2019, 03:33 AM

They are monsterous machines for sure. 61hp and 47ft-lbs completely stock and a wet weight of 317lbs. They were called Big Red Pigs for a reason, but my goodness are they amazingly capable machines, and the power was honestly not too hard to manage. I have had the pleasure of riding one a couple of times, and they just felt built to fit me. I would have to toss a few modern CRF450 components on it, mainly forks and the 450L lighting package.

So in Hawk related news. I have the tracking info for the cam. It is sitting waiting to be shipped off. I decided I may as well do some other things while I have the motor apart, so I ordered a new piston and ring kit just to refresh the motor from my abuse of dialing in carbs and whatnot. The piston I ordered has whatever that black coating is on the crown. Not sure if it will make any sort of difference but it's so cheap I may as well right? Full gasket and O ring kit coming with it and some new cam follower arms to go with the cam as well.

I do want to look into the clutch as well as I would at least like to upgrade the clutch springs to get a little more clamping power. I haven't had any real clutch issues, but it can't hurt. EBC clutch springs are fairly inexpensive anyway, so again, why not?

Yeah Dan, it's just as fun to make a slow engine faster as it is to make a fast engine faster. The mechanical mind just likes to tinker.

Completely true! I just enjoy the challenge more than anything.

Update on the cam order. The cam is now in customs and has been for 3 days now. I know it can take up to a couple of weeks to clear before it is then shipped on from there. Hopefully the cam arrives by mid november.

Still waiting on my Aliexpress ordered goodies, but they should be arriving soon.

I decided to order a new cylinder to go with the piston and rings as a precaution, just in case the original cylinder is potentially scored. I figure for $44, why not? At the very least I can have a backup ready to go.

Temps and weather are supposed to be quite favorable today, so I may even get a short ride in.

Megadan · 11-12-2019, 05:19 PM

Cam arrived today. Got my new cylinder in as well. Just waiting on the cam followers, gaskets, and piston kit. Pictures to follow along with the contact information for ordering the camshaft. Just have to wait until I get home first.

So, as promised...

I will start with the information on where I ordered mine, as well as a second alternative. The camshaft I ordered is model number 1010851 from WGK. This cam profile has no extra lift, more duration, and a flatter peak for increased "overlap" between the two valves. It is designed/intended to be installed with no modifications to the engine for clearance reasons and will shift the power band of the motor up the RPM range, sacrificing some mid range power for more top end. Basically, if you are tired of your engine wheezing its way beyond 7000rpm, this will definitely solve that issue.
Cam spec card here (in Portugese, but its not hard to figure out). https://wgkindustria.com.br/wp-conte...CG-125-OHV.pdf

I ordered my camshaft by e-mailing RB Motos in Brazil directly, found here: sac@rbmotos.com.br
I got in contact with a person who spoke decent enough English and I simply stated that I wanted to purchase the WGK 1010851 camshaft. I was able to place my order through them by having them setup and send an invoice via Paypal through which I paid. Total cost for all things involved, $95. Time frame was pretty typical for most international orders I have made, so expect to wait 3 or 4 weeks.

Alternative option is to talk to a gentleman that works at/with WGK more directly. I asked if he would be ok with me sharing his information to others here that may want to order anything from WGK and he agreed. His contact name is Douglas Carvalho, E-mail is douglasernani@hotmail.com He speaks pretty darn good English too.

In regards to the fitment, I can understand why many would hesitate to drop this kind of money on something that doesn't show a listing to work specifically with a CG250 engine. I took the leap because from every bit of information I could find, the specs of the camshafts themselves are the same across almost every model with the only difference being how the cam is mounted to the gear. One style is via snap ring, and the other is a press fit. I confirmed with two different Hawk owners that had to tear down their engine that our engines use the snap ring style camshafts, so I ordered with some confidence. That said, if you want to eliminate any and all guess work when it comes to your money, then the only way to know 100% for sure would be to tear down your motor far enough to remove the camshaft.

In short, do your due diligence or order at your own risk.

Moving on to pictures. I actually got the cylinder and piston in along with the camshaft. So all I am waiting on at this point is the cam followers and the gasket kit.

Maybe, just maybe, I can get it installed in an easy weekend and get at least a break in run going, but the weather turned south really quick with the high temps now sitting in the 20's, so I am not sure how soon I will be able to actually get it up and running. Fingers crossed for at least some 40 or 50 degree weather here soon.

I already gapped the rings and checked the piston to wall clearance at a few points. So far everything is within spec, which is nice.

Thanks

Nice!

Your house is heated right? I would have that sucker inside working on it or get a heater for the garage. lol I picked up a propane heater over the weekend. My neighbor was cleaning out his shed and was throwing it a way. I asked him what was wrong with it. He said nothing, just don't need it. Took it home and hooked propane up and it fired right up. I'm set for winter projects now.

I consider mine semi-climate controlled. It has a vent straight off the HVAC into the garage, but the garage isn't the most well sealed at the door either. For the most part the garage stays comfortable enough, if not toasty. My bigger issue with it getting super cold is being able to simply ride/run the bike once it is back together.

Maybe you should set up a PayPal to do a Dyno run before and after. I'd be interested in seeing the number difference, and I'd contribute.
