fixing it now :066:

Done!

Kev any other gremlin you find a solution for please let us know thanks.

Engine Breather
 

Something else I have done is disconnect the engine breather pipe from the airbox. Blocked the airbox side, fitted a L pipe to the existing pipe, connected a new 13mm ID pipe to the L pipe & routed the pipe down between the swinging arm & the motor. You can get a plastic L pipe from the local hardware shop, irrigation section.

This is so you get pure air into the airbox & not rebreathed engine fumes. Better Air more power.

They only do this for emission control.

Another interesting mod Kevin my old mate, how's about pictures and examples please?
Thanks

[ATTACH] Attachment 190[/ATTACH] The photos, engine breather mod. Don't forget to block off the Airbox after the mod.

Will take home my camera tomorrow, it's at work. Photo's taken by camera phone. Will post clearer photo's tomorrow night.

Kev ,do you know if this mod will have any effect on bikes that have power commaders and bikes that have had dyno runs,or is it a straight forward mod.???

Hi buck.

This mod is for all bikes, no matter what mod it has had.

In theory the purer the oxygen the bigger the bang. Oxygen levels change from city riding to country riding, so this mod really only makes sure you have the best oxygen molecules wherever you are riding.

A motor can only induct a certain swept volume of Air/Fuel usually 14.7 parts of Air to 1 part Fuel in the ideal. So making sure you have the best 14.7 parts of oxygen molecules is the ideal.

I remove my engine breather from the Airbox, for this reason. No use in rebreathing hot engine fumes, when you need cold condensed air for the big bang.

Ok gotcha,i was concerned it might give problems once people have had a dyno set up and doing this mod would result in having to put it through another run to set it up again.

Great! I have also been thinking of doing this mod. Now i got some great ideas of how to do. I was thinking of fitting a filter at first but now i will go for the "L" tube.

But what on earth is that "hose mod" you have done to the air box???? Seen in the middle pic.
You are not leading in unfiltered air are you?!?!???

The hose mod
 

The Hose Mod

Ok, I have been caught. Another mod by Kev.

Back to the Hose Mod. The standard air filter area is 9768mm sq in area. With the snorkel removed from the Airbox, the intake area of the Airbox is 4000mm sq. So the Airbox is restricting the air flow through the filter by more then half, not good.

I drilled two holes 33mm in diameter, one on the right side of the airbox & the other next to the removed snorkel. Then got two L pipes with the ID of 30mm with an extension tube between the L pipes, as seen in the photo & fitted it to the side of the airbox. Away from any water entry.

I also cut the removed snorkel hole bigger from 4000m sq to 5500mm sq. Cut was made in one piece so I can glue it back when I sell the bike. The two holes can also be blocked with 35mm grommets. All parts bought from the local hardware, L pipes from the irrigation section.

The extra air made a big difference in acceleration. More Air meant, more Fuel needed, that's where the Kev variable resister mod came in handy.

I did not want to fit a 2nd stage filter for fear of water entry or water saturation of the cotton in the filter.
