Can you please guide me in the right direction. I have a 421 Athena banshee with 34mm Kehlins carbs. On the low end the bike bogs out and when you get into the power band it begins to run better. I backed out the air scew and every time I backed out the screws the bike ran better. Do I need to change the main jet to a smaller jet or change the small main jet. To me it seems like the bike is chocking and needs more air

You need to run CEL needles in the carbs are it will never run right.

It’s the Oring on the aluminum tube that is in the clutch cover. Pull the clutch cover and replace the Oring on the aluminum tube that sticks out of the side case.

Hi mate, im doing a build using athena 392 kit, the manual says to mod the reed stoppers to 22mm, does this sound correct? Do you know the stock distance between the reed stoppers on a stock cage Great vids!!

If you are going to use reed stoppers modify them open as far as you can. At a point they won’t fit into the intakes. I don’t ever run the reed stoppers myself.

Be sure to Remove the spring clamp on the rear rubber boot near the 8 bolt and replace with a hose clamp. If you do not replace the spring clamp, you will blow the rubber boot right off and spray coolant all over the engine bay.

Don’t know why people refer to that as the flywheel, it is a rotor for the generator and is listed as such by Yamaha. Yes it adds mass to the rotating assembly kinda like a flywheel but not by design, as a 2 stroke fires every rotation it is not as reliant on flywheel mass to smooth out power transmission between firing events. You can lighten a 2 stroke rotor without any major negative and more positives, if you lighten a 4 stroke flywheel it will become jerky on the low end due to the exhaust stroke. Also engineers have noted that you see more return putting the weight on the clutch basket allows for less bogging due to the rotating mass directly acting on the drive line, as weight opposite of the drive side is transferred through the crank increasing the twisting load on it.

My daughter's boyfriend installed a pyramid reed set up from Duncan racing in my daughter's Yamaha blaster. He forgot or never thought to rejet....I believe it ran too lean. It has a full port n polish and 34mm intake along with a 34mm mikuni carb, it had a 10.3:1 piston. Installing a wisco pro lite piston this time. I'm sure it will loose a little hp. My question is any aftermarket exhaust pipe do you recommend? To help reclaim some hp?

@@herrjugsracing7816 thanks for replying sir. Say, I have a 1995 all stock chassis machine, all matching numbers/title (1owner me) W/ONLY aftermarket pipes and cool head. It’s been sitting for around 17yrs. Its got 185 compression on both sides mostly because I fogged the engine before I parked it. I gave it a well deserved bath and when I took the seat off I noticed duck-tape on the snorkel tube (good idea) and the air filter looks just as I remembered.. new!! BUT when I touched it the damn thing FELL TO PIECES.. so I go to cycle craft inc where I bought it and they are NOT THERE ANYMORE (big surprise) but throttle monkey custom cycles is. Regardless but none the less got a new filter and 5gal 110fuel mixed it up 100ml to 1gal (37:1) approx. and it started rite up but the clutch isn’t disengaging so it shuts the engine down when I put it in gear. Should I just change the transmission oil and roll-start it and hopefully it kicks something loose because it was perfect when I parked it.

The stage II isn’t a great tune kit. The car is faster overall but the 60 foot suffers as a drag racer. It is all top end. Only got a tenth better out of it in the 1/4 mile. That Charger in the video is putting down 1000 hp. I might be putting down 800 hp. The Charger is clearly faster.
