What a great website, which means a great bunch of enthusiasts. Thanks for all of the threads I have read today.

One thing I need to know is where to get a good manual? I bought the Yamaha manual, but it is pretty limited. I need to remove the starter and replace the starter clutch system ( on a 20-ride bike, 03 and it growled when new, according to the original owner) and the Service manual doesn't show chit ( unless I am blind).

Second is, for a stock cammed trail riding application which slip on or full exhaust is suggested? I am interested in the HMF quiet series, and will call them for a recommendation, but I am not sure if their up-to-date on technology, or if someone else is better for the $$. I will ride on both forrest service trails/ logging roads and state parks, so I believe I need the 101 DB or less setup.

Only thing I can gather from past threads is probably keeping a stock headpipe ( size anyway) will probably keep the low end grunt, while allowing some good gains. I know enlarging a headpipe usually gaiuns on the top end, but at a severe loss on the bottom unless you undergear the front sprocket.

Thanks for any suggestions. What an improvement ( Raptor) over my old Suz 230 quadsport I had back in the early 90's...........

Here's the factory manual in pdf.

It's in the AC magnito section...

Scott at West Coast ATV in Elk Gorve has installed the aftermarket starter clutch on my buddies bike. Check out Raptor Tranny dot Com for info including detailed instalation instructions. Raptor Tranny

Thanks for the great information and links.

It looks like the LA system is the one to get.

I have a 2003 as well and my starter is getting worse, what a joke! Looks like the LA is the way to go for me as well.

 

I have a full Yoshimira Comp system on my 01 Raptor, with a K&N and holes in the airbox lid and 150-155 main jets. It lost no low end power with the full system including headpipe, in fact gained a bunch. I like the Yoshi because it's quieter than many others, well built, and has the spark arrestor. I also geared it down to a 12-42 gearing (stock was 13-40 I think) but the 01 tranny has funky ratios too. Welcome to the nuthouse!

Thanks for the information.I will look into the Yoshi pipe, glad to hear bottom end was not lost. I see on HMF's website it shows a 5 hp increase at 2500, and 4 hp with the full system ( so the headpipe does loose a little bottom end, it seems, but of course is MORE than stock!)

And thanks for the welcome. Going camping/ riding this weekend, we will see if I survive-lol.

Head up to Sand Mt. for Labor Day Weekend.

Mostly a DS group but, they will be sure to show you where the main hill is [img]i/expressions/face-icon-small-wink.gif[/img]

 

I'll second the Yosh exhaust. I had that on my 660 and it worked well and was not too loud.
Also, you can get it at Rocky Mtn ATV for a good price.
