Can some one tell me how to "correctly" install a snorkel and all breather in a 300 Honda?????

'00 Red Honda 300 - GNB DirtDevils
'00 Green Eton 90 - Highlifter Lift Kit, Extra lights, Warn winch, 22"x9" bearclaws on rear, heated grips, jet kit.
'97 CR 125
'8? 185 S
Monster-Kart with 185 S and i think 22" Wooly Buggers on back

 

Remove the stock snorkel. Place a 2 inch peice of 1 1/4 schedule 20 white pvc (THIN STUFF) use a
1 1/4 to 1 1/2 adapter (Nipple) Then use black schedule 80 pVC with the proper angles to get it to the top of the front rack but out of your way. Then use a threaded mail to threaded female and then a 90 angle go up one foot and the another 90 angle. This way when you are just riding trails you can put it down and it won't get broken. When you get in water, raise it up.

By going up to 1 1/2 near the air box it is not necessary to rejet. This has been my experience. You should always watch your plug though to make sure the bike does not run lean and over heat.

Hope this helps.

what about the Rear Exhaust? or should i bother with it?

 

No. If your intake is snorkeled properly and the drain line for your carb is plugged. It will not die from the back pressure.

The drain line for your carb is most important. If you ever notice people draining their carb after being in deep water 99times out of 100 it is because of a faulty check valve in the carb drain line. Remember to unplug after riding and definitely before transporting.

Enjoy the swim!

I used a 6 foot 1 1/2" ID swimming pool hose for mine. It fit snug in the existing breather box hole. Then I used gasket sealer to seal it up. The swimming pool hose is good b/c it is flexible and you don't have to worry about all the elbows on PVC pipes or it breaking. You do need to run breather lines for front and rear differential, front and rear brakes, crank case vent, and your carburetor breather. If you don't you will have big problems in the future. All are 5/32" lines except the crank case vent, which is 1/2". You need to seal the air box and your spark plug, too. Have fun in your new submarine!
