IQR pipe issues....any suggestions?

[himarker]

I bought a '06 IQR chassis and im in the process of installing my 900 UBR. At one point the sled had a 800 non-ves in it and the kid sold me the pipes for that motor when i bought the chassis. I talked to Fastrax, and they told me that those pipes would not work. The stinger size at the outlet of the pipe needs to be 33-35mm in dia. The crankshops that i bought with the chasis are only 30mm. My SLP race twins that i had on my 900 in my edge chassis are 35-336mm on the outlet. I dont know what pipes to use. Do i chop up my SLP's and make them fit, or do i put a bigger end on the crankshops and fit the inlet flangto to mathc my motor and run them? I know this is confusing as h#ll, but i need some help. Thanks for the help

Cut up the SLP pipes....The non-VES pipes will not work the expansion chamber is tuned differently. Like I said in the PM, just take your time and get them to fit really well. The reason the end needs to be larger is to flow more air. If you don't run the larger pipe you will notice a bogg especially when hitting the hill in consecutive runs or when you are boondocking. i have ran into this problem myself. I had Ted at Terra-Alps set me up with his front dump and that setup changed the end of the pipes to a larger diameter. All of my bogging issues went away and I had better bottom end etc. You will really notice the issue with your 900 as I am running the 910 and it took me about a year to finally change things up and getting rid of the bog. You also want as much air flowing into your motor and you will want it to be consistant temps. Let me know if you need any other info. or specs.
