CRF150RB -- Thanks Kitaco
By Jerry Matta
Well after blowing up my Kitaco head, valves, $25 plug, and piston, then 4 months later breaking the crank; I've given up on trying to make my little XR100 go fast. By the way, I emailed Kitaco and they said the stock flywheel is too heavy. Well, I didn't see that in the advertisements or instructions. So I picked up a used CRF150RB for a decent price and went to work on it. I'm still not finished, but pretty close. List of things: Suspension 5.8 rear spring and .40 forks springs, valved form my weight and some secrete tricks to make the forks work better, Renthal CRF mini highs, BRP clamp that move the bars out, R&D power Bowl with a 48 pilot, jetting is spot on, DMC pipe, New Bridgstones, Regina Gold chain. The Bling would be: Wheels, plastics, graphics, all hoses. Still need to install foot pegs (already had my foot hit the rear wheel ... twice), Hotcam (stage 1), A real front brake (450 twin piston caliper and steel braided line), maybe a smaller rear sprocket or bigger front.

I've been putting off getting a TTR125 forever. Well of course, since it was a Yamaha. I had my little tricked out 120cc CRF80 that flew. So why would I want any other bike? I didn't, until all of the SoCal group were riding the track behind my house and I rode one of their TTR's. My first thought was, "Holy Crap!! I don't feel any of the bumps that were killing me on my bike." I was pretty much sold at that point. So my hunt was on for a TTR. I was going to get a '06 when the '07's came out or maybe get a '06 from some dealership out here that sells them for $2499 OTD. I figured that I would need about $1000 more to get it to work or at least be rideable. So I was going to have to sell my two CRF80's and all my after market parts. Luckily, I have a friend that is a Harvard Psyche school mental case. The type of guy who never has the right bike and gets a new bike every two months and three storage units worth of crap. So I picked it up with a 1/2 a ride and with front and rear BBR springs, cradle, tall seat, and Renthals already installed for less than a new bike. I couldn't pass it up. And the good news was, the sale of my other stuff paid for everything. So obviously, I would need to do some work to get it work for me. This is where BBR comes in. They are the only company that makes a full line of parts for the TTR125. Every part I bought for this bike has nothing to do with "Bling", but everything to do with utility. I'll do a list with the purpose of the product. In no real order.
BBR Products: Pipe, seat, shifter, rear spring, cradle, chain
guide, foot pegs, free flow filter, carb intake, BBR Rev box.
For the forks, I got some YZ85 forks off ebay and with a spacer here and spacer there, they are pretty close to a bolt on as you can get. The only issue is they soft, real soft. So I took them over to Jason at Fineline Suspension in Huntington Beach and he valved them and got me some .44 springs. Now they work. Other things I have are a CR85 master cylinder and brake line and some bar risers to get the forks a little higher. Also, the stock carb is junk. Some can work and some don't. Mine didn't. So I replaced it with a 200x carb off my xr120. It works twice as good. Forget trying to jet the stock pile carb, just get a 200x carb. I also had Dave Miller from DMC lighten the flywheel. You can't take as much off a electric start flywheel as a non-electric start one, but still a good 8-12 oz came off. I didn't have a scale to get the exact amount. About the only thing left to do is a BBR 150cc kit, which will be in next week.
On the track, it's night and day from stock. Even though the motor hasn't been bored, it's still has more bottom and pulls the 14t front sprocket better than the stock motor pulled the original 13t. The suspension is like real suspension, I can hit whoops now and not worry about the back kicking me side ways. Overall, it just a solid bike.
Part 2: Wheels
For part 2, I replaced the weak steal rims and spokes for a set of aluminum rims and heavy duty spokes. It was kind of a chore, but it only took a day. Plus, it enhances the look two fold. I also wrote a "how to" on lacing up TTR rims. Click Here.
Part 3: BBR 150cc Kit
There are definitely things to know ahead of time, if you haven't installed a big bore kit on a TTR before, which I haven't.
Tip 1: Take the motor out. I didn't, but it would have save
me time and aggravation if I would have.
with Kitaco 145cc
By Jerry Matta
Well this has been a long and arduous process. What started off as a pile of parts has turned into a fire breathing race bike that can hang with about any bike on a track. (Full article)
Kitaco 145cc Kit goes Boom!!!!
Well after eight months of shear fun, my $1150 Kitaco 145cc Kit grenaded into a very expensive fix. The head is savable, but hammered, the valves are history ($150 a pair), the piston has a sunroof, and the cylinder needs a sleeve ($150).
Fixed by Ray Groom of Spike Racing
Part 2 -- Kit Goes Boom Again!!!
So now, I running a stock head on a bored amd stroked motor. No more Kitaco.
BBR150f with DMC Twin Pipes
Although the bike has been complete for a few months now, I hadn't got
around to taking pics. Well, I finally did and here they are. This bike is
almost too nice to ride. Fortunately, when it comes time to take her out, I
have the necessary spare parts so the nice stuff won't get ruined, i.e.,
extra set of wheels from the CR85 donor bike, extra set of radiator shrouds
and the BBR D-Section pipe and header that came with the frame kit -- these
will go on the bike for its virgin ride (I am a woods rider but will keep
her off the really gnarly stuff).

DMC CR85/100 Street Legal
By Jerry Matta
Even though I don't ride this bike too much, this my favorite bike. Mainly because of it's uniqueness of being only one of a few street legal conversions in California. I also went way out of my way to make this street safe with full size mirrors that dont move when you ride and you can actually see the cars behind you. Plus it has real front brakes with a DRZ400 supermoto master cylinder, steel braded line, and a twin piston caliper. The Trail Tech computer has all kinds of info even including air temperature. The 120 scoots pretty good, but eventually I want to put in a Trail Bikes 132cc kit. Other things I would like to add is a rack that can hold a calaspable fishing pole and a small pack.

120cc Vintage XR75 Racer
Vacation in SoCal
This summer if you need a place to stay, I'm am renting out rooms at my house for $75 a night for two people. I'm located 25 minutes from Glen Helen, 13 minutes from Starwest, 20 minutes from Perris Raceway, and 35 minutes from Elsinore and 40 minutes from Disneyland. I have a little backyard track if you have a 50 or 110 (please bring a stock pipe for neighbors), plus a garage to store your bike, tools, washer/dryer for gear and clothes, pressure washer to wash your bike. It's not the Hilton, but at least your bikes won't get ripped off, plus you don't have to worry about smelly gear and not being able to clean your air filters or change your oil. Plus, I have a hook up with a local Honda dealer, so if your bike breaks, I can get the parts and gear at a discount.
If you're interested email me at firstname.lastname@example.org

Thanks to those over at BBR motorsports Chris "the Aussie" Alamangos picked
up a CRF150 roller, which was brand new still in the crate. He then pick
up an pretty clean XL200 with 1700 miles on it. With absolutely no modification
he took the XL motor and bolted it up to the 150. There are some concerns
with the manifold and the countershaft sprocket being off a little, but it's not
that big of a deal. The chain hasn't jump ship yet. Anyway, as most of you
know the XL isn't the fastest motor, the gear ratios are too
wide and everything seems to be against, from it's reverse dome 9:1 piston, to a
pencil for a camshaft.

Major Gains in Engine Performance
So you think we at SoCal XR's do nothing all day but play video games and shop on EBay. Well, you'd be right. However, we actually got off our duff and did something. I took my bike to Dave Miller the father of mini-bikes, along with the best tuner in the industry, and what we came up with, you can check out on the dyno chart. We started with my 123cc motor, with a 69/68 Web cam, Stock valves, 200 carb, 50/50 gas, standard Miller pipe, with just a slight clean up on the ports. This is your basic modified motor, nothing real special, in fact it wasn't faster than anybody else's' XR, faster than TTR's , But not XR's. Anyway, 59 dyno runs later, we managed to get my average motor well above average. I can't tell you what we did, or even the numbers, but you can see for yourself the results. Also, look how far it revved. Yes, that's more than 14 grand and it will go more.
If you have any pictures, race info, or anything, (no negative E-mail, unless your girlfriend just broke up with you and now she's available) please, E-mail me at email@example.com and I will post it ASAP.
