It's not necessarily the rider, but the engine. Why break balls when it's a chinagirl probrem?

Also, not everyone's a little dude like you.
I disagree with both points.

First, build an engine that can endure the entire race. If you feel that it can't finish the race then use a smarter strategy to ensure you finish the race.

second, I'm probably one of the heavier racers out there pushing 200#.

Magrider & I swapped bikes in Willow Springs a few years back. I had his faster bike & he was on my slower bike. I couldn't shake him loose, it's not just the engine - it's both, engine, and skills of the rider.

The 4-strokers are ready to go right now. Really liking the Honda GC160, so smooth and runs great. Bolted a mikuni carb on and it ran with slight idle adjustment, amazing!

If you can get some racers in the 50cc class that would be great. I'm doubtful that the 66cc bike will be ready for the first race this season, but it won't stop me from working on it to the last day. No brakes, exhaust pipe not figured out yet, engine not yet mounted and no drivetrain. A lot of work to do.

Photos of the bikes lined up and a couple detail shots - custom springer front end, engine mount for the "pro" bike and the GC160 slipped into the old frame.
You are well armed my friend, a nice fleet of well prepared race bikes! Look forward to seeing you at the races as always Brian. Hope have a bike to compete on.....just one will do laff

See ya soon.......scotto-

If I brought this bike.......

.......what class would I race it in? It's 3-4hp basically stock 99cc 4-stroke.

I don't want to bring a bike that that is not going to be competitive in it's class and that is why I'm asking this question that has not been answered yet.

We're talking about chinagirls here. If one is playing the chinese lottery, one is going to get chinese results.
That means rebuilding often or hiding reality through propaganda. The fastest guy in your class practically rebuilds between sessions.

There's a pic floating around somewhere of me talking to you (El Dorado ride), and you look like a midget compared to me. I'm a lean 230.

I know you're a competitive dude, and you are one heckuva rider. Much respect for that. But your logic seems to miss the bigger picture.

Magrider & I swapped bikes in Willow Springs a few years back. I had his faster bike & he was on my slower bike. I couldn't shake him loose, it's not just the engine - it's both, engine, and skills of the rider.
Well duh, you're not telling me anything new, dude. I was racing BMX in the 80's. I no longer compete, but I've been through that rodeo.
Anyway, you completely missed my point, which from all your posts I've seen, is a very common thing for you :rolleyes:

If you two want to use an engine that showcases your racing skills, use a Huasheng or GXH50. There's very few hop-up parts for them, they don't have a removable cylinder head, and that means you are pretty much equal with your peers on power production. Well, aside from the pedal question. Maybe then you two can spend more time perfecting your lines and less time complaining about stuff. Just my humble opinion.

I want to thank Fred of CR Machine for his very generous
sponsorship of motorized bicycle racing with a couple of his
billet high performance racing cylinder heads for the 66cc engines.

The fast guys on the track in the 66 cc 2 Stroke Pro Class use these
heads because they are the best performance head on the market bar none.

Check out all versions of CR Machine's heads here:www.crmachine.com




CR Machine just came out with this product for all you guys that don't have brass nuts
for your special build.


Motorized bicycle 6 x 1.0 mm tall brass exhaust nuts pkg. of 2

http://www.ebay.com/itm/130880288717

Well, I just had to make some of these tall nuts!
I like to fit these nuts to any cylinder body that I sell, but now you can get these high quality nuts separately.

These are fully machined from 3/8 inch brass hex stock for a superior fit and finish.

This material is traditional for securing exhaust flanges.




The heads are big chunks of aluminum, that's some set up cutting the fins!!!

weird. brass is such a soft metal, i wouldn't think they'd hold up on an exhaust. i've used them for decoration, and they strip really easy.

i've used copper nuts on the exhaust before, and after taking them off and putting them on a few times, they won't hold anymore.

thems are awesome heads, though...

Scotto, we are bringing a stock 88cc bike with lights, fenders and saddlebags (150+pounds) to race mid-range!
Would be great to have you there!

My point is to build the most reliable engine you can that will finish the race. With all motor sports builders will push their engines to the point of failure. If it is a 1 lap race build an engine for 1 lap, 20 lap race build an engine for a 20 lap race not a 1 lap race.

To degrade someone for something they have no control over like height and call them a ‘midget’ is offensive.

I think all classes showcase rider skill, and If I can place before you with my POS engine then enough said.
