I decided to purchase a new 2003 Prairie 650 in Camo. I have read a few post about these bikes, but honestly I don't fully understand the mods. I love to tinker with stuff. I just sold my Ducati 748 that was fully modified and now I am purchasing this new toy. Please help me modify this. I read alot about a black spring, but I am not sure what that does. Also I have read the tires are trash, what would you put on. If this was your bike and you could build it the way you wanted what would you do. I have done many things on my Ducati that I would have done different, that cost me more to do things twice, and I am sure you guys have too. Have fun and build the Prairie 650 of your dreams. I will report on my progress and tell you guys the things I do. I have also read about snorkles and filters, but I am clueless.

 

the black spring helps on belt life, I'm thinking 26 mudruners is a start. If you want more you snorkel, jet kit, twinair filter and order a new CDI box.

 

What kind of Snorkle, Jet Kit, CDI, and Filter do you recommend?

 

I like the dimond g racing snokel and run K&N jet kit but people like running the combos jets. and people like the twinair more than K&N I run the K&N because that was the only one I could get at the time

 

Welcome to the fun ;-) Go the NYROC's site for some excellent information on the P650 and related mods. Here is my little disertation. (Can you tell I'm tired of sitting inside and desperately need some time on my 650 - tomorrow I'm getting out)

The mods will depend a bit on where and how you ride. The good news is that the majority of the mods are not excessively expensive, so if you like to do the work it's not too painful to experiment.

My personal preferences are in my sig. below. I recommend the Keihin jets as they are only about $7 or $8 and seem to have a strong following over the Dynojet jets (K&N Power Kit is the same jets, but no longer in production as K&N). You should get a Reed Prince type phillips screwdriver for working on the carb screws. They are cranked on way too tight from the factory and you can strip the heads. Sears has them as I'm sure other places do as well.

Tires are pretty personal things - it can be like discussing religion around here ;-) - so take into consideration where you ride and what type of riding you do. The Mudlites are my favorite because I ride a mix of trails and mud. If we have another extremely dry summer this year I'll be going to ATR Holeshots for the really dry months. I like my 26" Mudlites a lot though.

I have the DiamondG Snorkle and recommend it. There are some lower cost options like the NAPA hose and using PVC. I like the fit of the DG Snorkle but can't argue that it is definately better that the NAPA hose or PVC.

The one thing you MUST get is the EPI black spring for the secondary. It is inexpensive and makes a significant improvement. If your riding style can take the 'snap' of a higher stall speed, consider the EPI red spring for the primary. They are both around $20.

I use the TwinAir filter, which supposedly does not flow as free as a K&N, because it flows more freely than stock while still filtering the fine stuff out. A TwinAir needs to be cleaned more often than the K&N for that reason.

Some type of CV Boot guard is useful. The stock plastic ones didn't hold up well for me, which could be a function of where I ride. I'm using OxLite CV guards and there are many other good ones out there.

Peace,
SgtRock

 

SGT,

Thank you for the tips. I am keeping a open mind and looking for all opinions. Only I can make the choices for myself, and if I make a mistake it's my own fault and not anyone elses. I can't wait to start riding.

 

What is the web address for NYROC site?

 

find his post and his site is in his signature.

 

sgt rock is right on target in my opinion. If you dont ride thick mud, get the holeshot atr's. I have them and love them, the handling and hookup on trails is way better than stock, and you have the peace of mind with a 6ply tire thickness compared to the stock 2.

As far as jetting and other mods, I haven't gone there. The v-twin makes such great power as it is, I'm just having fun riding the heck out of it, and not worrying. I'm always tempted to modify things, and every time I do I find myself spending less time riding, and more time riding and listening to the engine, adjusting carbs, etc. If you must go faster though, there are plenty of folks here that have done extensive mods and can help guide you along. Talk to alltoys if you want to get nuts! [img]i/expressions/face-icon-small-wink.gif[/img]
