I know 100% on the X & R models when you are cruising around 3000 - 4000RPM or just opening the throttle with an open air box with the AIS system connected as standard, the AIS valve opens at this time for emission control you get an exhaust pulse wave back into the air box, sounds like a beating drumming sound, blocking the AIS pipe eliminates this noise as well as the popping back, the reduction in popping back depends on the year & ECU fitted to the bike.

If you have the snorkel in on a standard air box the AIS intake noise is greatly reduced & you would not hear any intake noise frrm the exhaust system.

No need to remove the AIS system just block the intake pipe as shown in the link I posted.

is it really possible to accelarate the Ten hard below 3000rpm in 4th and 5th gear without the chain slapping like mad? My XTR (same mods) certainly doesn't like it and i didn't expect the fuel mods to cure that.

#O2 controller update#

Guys I have the very first case of possible water entry into the connectors of a O2 controller with no damage to the bike, can I ask for everyone who has a O2 controller to use electrical tape & tape up the connectors & wires to the connectors & to make sure they are not exposed directly to the rain.

I buy the best connects that money can buy & surposed to be water proof, I have sold huindredes of these controllers & not had a water problems before, I react to things like this straight away.

I have done some water testing this morning & they seem to be fine with the connector completely submerged in water, the mod box is epoxy together so should be fine.

I have changed the installatiuon instructions to say the connectors need to placed out of direct rain & taped up. I will apply epoxy to all future mods where the wire enter the connectors.

Thanks Kev

Phew looks like I jumped the gun the O2 controller was not the guys problem, there was NO water entry into the mod so back to 100% success rate. :drool[1]:

Never mind I would still recommend you insulation tape up the wires & connectors if you ride in very rainy conditions. I have done some water tests on the connectors over the last 24hrs with the connectors completely submerged in water with no leaks into the connectors after 24hrs so looks like they are doing their job.

Guys I have just reduced the price of my mods on EBay if anyone is interested. http://www.ebay.com.au/sch/7416kevinh/m.html?item=141188157254&ViewItem=&rt=nc&_trksid=p 2047675.l2562

I'm interested kev...would it be easier to buy straightfoff e Bay or from yourself here.

BEing an XT Supporter, if you buy by pm from Kev directly you get a discount.

As of last night the O2 controllers on Ebay were discounted for the next two weeks, for supporters I can take the Ebay fees off the cost if bought directly from me.
