I was just a mess'n witcha n20

I'm calling you out n2otoofast4u, come back to Little Sahara and bring a bike this time so I can beat you by 10 to 20 links.

Look at the Otto 18-253 ball cap, Its a low profile with a very soft crown. Best looking and best fitting ball cap I have ever had, I choose to wear it over all of my fitted caps. They are made well and don't cost a lot.

All Inframes come standard with long lasting stainless steel packing. Stainless steel packing prevents repacking of mufflers every few months. However, we know some of our customers might need or prefer a quieter tone. So we do offer fiber glass packing. Please specify during checkout (note to seller) if you would like the fiber glass option. Otherwise your Inframes will arrive with stainless steel for the packing. We also offer a large stinger option for (cheetahs, twisters and super cubs). Please specify if you would like the larger stinger as well. *OPTIONAL FIBER GLASS PACKING & LARGER STINGER ARE OFFERED TO YOU FREE OF CHARGE*

The 78mm pistons should have far less crank failures than the 85mm piston engines have been having, the crank costs 2800 dollars. The 78mm bore Cougar has huge exhaust ports and huge triple ports, can be ported far bigger than any DM could ever be. Jim has said this engine would make 275 un-ported because all the metal that has to be removed on a DM exhaust port is already gone, very little porting is needed to get to 325 horsepower with four cylinders sharing loses through the transmission. There are pipes on the market that are proven to make 80+ horsepower per hole on engines this size and you don't have to get high dollar handconed pipes built.

I am selling my new 4 cylinder Cougar parts due to lack of time to build a new bike. Parts for sale Matton cases with transmission inspection port and transmission output support cover with special sprocket nut. 5 78x74 Cougar cylinders (as cast) Crankworks crankshaft 4 headshells 4 exhaust flanges Cylinder studs for Cougar Price 6000 plus shipping (cost is over 11000), the lockup cover in the picture is not part of this sell.

My engine design and simulation software uses Young's Modulus to study reed behavior and lift, the software will predict total reed lift, reed cage time/area, actual time/area across the petals, reed petal frequency, intake velocity, BMEP, direction of flow at important timing events and amplitude inside the intake pipe as the reed petals close. The software will predict an unstable reed petal if the lift ratio is much above 30% (reed max lift divided by reed un-clamped length), If the reed is unstable and floats it will close late and the inertia of the intake pipe will have to do most of the work keeping the charge in the crankcase. If everything goes right the reed closes on time and the charge inside the intake pipe sneaks into the crankcase just as the reed petals close, this will raise pressure inside the crankcase much like a very small supercharger would do. Cubs above 392 cc will have excessive primary compression and reed tip ratios at and above 30% unless the builder has adjusted it. The reed stops on the VF4 will help stable the reeds on these engines or so the math says. To learn more read Gordon Blair's Design and Simulation of Two-stroke Engines (Chapter 6), for the math Gordon Blair's The Basic Design of Two-stroke Engines and Google Young's Modulus.

I did simulation on the VF3 and VF4 and agree 100% with John on this one, simulation shows gains on 4 mill and 10 mill engines. This reed cage helps with a problem that most don't even know they have (reed tip ratio above 30%).

The corrected horse-power numbers at Denver will not be the same as sea level numbers on a high output two stroke. There is no air at 5000 feet for the engine to produce the same heat as it would at sea level, so a large volume expansion chamber will not work the same way at 5000 feet as it does at sea level. You have to run chambers with very little volume for that size of engine to make any real power, no correction factor will compensate for an expansion chamber that is too big for the amount of heat that is being pumped into it.

The correction factor can be changed anytime after a dyno pull, you can chose from uncorrected, std, sae and one other on a Dynojet. You can print and compare runs with different correction factors at will. Heating the stack will raise the horsepower output and a simple turn of a potentiometer on the weather station will raise power output just as J-Madd said. There are lots of other ways to manipulate the output of a Dynojet that I did not mention.

Have your dyno day on a day that everyone can be there, I want to be there for every dyno pull that will be posted. I do not have a dyno, I have had an independent shop dyno and tune for all the dyno sheets I have and all are 100 percent legitimate. The elevation in Sweet Home OR is the same as Oklahoma, This makes me confident enough to say that any Redline tests on 100+ horse Cubs,Cheetahs,T-rex or Twister engines on gasoline will look just like the dyno sheets that Jim posted comparing Sniper in-frame to Shearer in-frame. At this dyno test I will put Sniper in-frame up against Shearer IF or OOF on 100+ horse gasoline engines. I will not say that Sniper is the best on cast Servals, lightly ported Servals and all cast Cubs. Good porting is mandatory for them to be a better pipe. Every dyno sheet Jim posted was on gasoline comparing Sniper to Shearer, gas is the fuel of choice for most of my customers and most people with in-frame pipes. I am free most any time and can stay a few days if needed to finish testing. Cameron, thank you for offering to do these tests and to set the record straight.

Cameron, when you post the sheets have the notes, run conditions and correction factor on the sheet for reference....Thanks Ragun, I put a 1 inch ID stinger on all big bore gas engines and a lot of alcohol engines. Ims, this set is standard with removable stingers.

That dyno setup should be good. I hate for anyone to get their pipes scratched swapping out pipes, I have a set of in-frame test pipes you can test with. Ragun, I have not tested ceramic or power coatings for power gains or loses.

Rocket and CPI will both do better in a pipe test than some think if the bike is geared to simulate the load of racing. Any large volume pipe needs the exhaust gasses to be at maximum temperature to come into sync. Any dyno runs that do not spin the drum close to 80 mph on a 85+ horse engine will not show true potential of the engine or pipes on an ATV dyno. A car dyno does not need that much gear with the large rollers. Low exhaust gas temperatures in a large volume pipe will stop expanding and tumble, this acts like a wall inside the pipe. A 17/41-43 gear works good on 20 inch tires and a 19/41-43 gear works good on 18 inch tires. Using an eddy-brake will only simulate racing with your foot on the rear brake and will not let the engine peak at its natural RPM. Dyno runs with too low of a gear ratio will almost always have a bigger numbers with a smaller volume pipe, smaller stingers help as well to get a flash number under geared.

Oh yea, it just pulls a very small amount of air from the choke horn. Some of the older Lectrons did not have chokes and or the holes drilled that feed the choke, that's why I mentioned a working choke.

Any use of housing insulation should be non formaldehyde.

Yes Rainman56, if you have a working choke, the kit allows you to run the metering rods two turns rich and allows the idle to be fully adjusted from the secondary idle screws. If you can bottom out the idle slide screws and still not get the engine to idle up high enough for a good stable idle and you have to lower the metering rods so low it stumbles in the midrange to get a good idle, this kit will work very well for you. The need for this kit is much higher on gas than alcohol, many new Lectron carbs ordered for a four stroke engine will come with similar screws already installed for easy idle adjustment. On a first time tune on gas and alcohol, this kit will save tuning time be allowing the engine to run and idle perfectly with less metering rod adjustments.

Congratulations Brad Painter for the wins in the 431cc-525cc and 526cc-650cc classes at the first race of the year, Brad won both classes with a 10 mill cub.

No brad I don't know his name but Jim does, he sold the pipe. That guy told the other guy with the YZ85 his pipe was built in California, so he don't know I built it.

I did pipes for two dirt-bike hill climbers running in West Virginia on the 400 foot hill, both have custom in-frame pipes, one is a 610 DM and the other is a YZ 85. I have been told the DM was the fastest on the hill last year (with a pro rider), but let me say this is secondhand information, will post some video if I get any. I'm sure Loco could get the scoop on this.
