I have a add in the seven days for free section.

What shockwave helix angle works best in a 08' Apex. Thanks

I would take your sled in and have the valve clearances checked. I have a 03 rx1 mnt. with 9680km. I sprayed for one season and this sled has seen a lot of WOT. I had checked my comp. before spraying and it was pretty much 200 across the board. Checked my comp. before this season and it was all...

sparkplugs I am going to try the Denso iridium IU31A plug. It is a colder plug yet.

For running at the higher elevations you need to address your carb float hight. I was at Revy a few years ago and my 03' RX1 would sputter and sometimes even quit at 6500ft and above. Scarry. The Mech. at the local yamaha dealer inspected my carbs and set the float hights at 13mm. Problem...

Tuck tape? Is that government issue.

I run nitrous also and have found the shockwave helix to be a great, quick, tunning tool. A 500rpm adjusting range is about right. I set my sled to run at 10,400 off nitrous. To run on nitrous I use the adjustable helix to set the sled up to run at 9,900. My nitrous wet system gives me a...

Thanks again for the obviously well informed replies. I will be thinking about this for a while yet. Good to belong to a community that readily shares their knowledge with fellow members.

Was talking to a friend of mine today. The question came up about the lack of a bov on a supercharger. Can anybody say if there would be a issue not running a bov on a supercharger. We got to wondering if you were wot and then get out of the throttle, would it take a bit before the motor would...

Great info guys. Thanks for the responses. Be reading allot too. Something that I have been wondering about but haven't picked up on yet. If you are running a s/c or turbo and clutched for a certain rpm off nos, what happens when you hit the nos and gain a bunch of rpms in reguards to boost...

Hi guys. I am currently running a 03'rx1mnt with a nx wet system. I am thinking about getting a supercharger. I checked the nos forum and went back about thirty pages in the turbo/supercharger section. Didn't see anything current on the subject. Is anybody out there running a supercharger and...

YUP

Problems, what a under statment. After my first trip to the mountains with the 03RXmnt, and being the only four stoke on the trip, well I had a few less friends, I was pissed at Yamaha and I just about had to see a shrink. Good thing I'm a stuborn basterd and loved the four stroke engine. All...

Looking for thoughts on why people are selling there Yamies for the same price that you would sell a two stroke for. Yamahas have the best fit and finish in the bussiness and we don't need a motor check till 20,000km. In fact there was one year where there were no warrenty issues recorded for...

A budy and I had to resort to buying a nitrous pump off of e-bay for $700 and we buy the nos in 65lb bottles for $400. About $6 a pound. We did this because buying nos in northern Alta. is a bit unreliable. When you want nos YOU WANT NOS. javascript:emoticon(':nos')...

I run a NX wet system with a sixty horse shot. RPMs jump up 1000rpm. I get about 8 10sec. runs. I love it.
