Ladies and Gentlemen,

I'm new to this forum .... so please bear with me ....

I have a '02 Kaw Prairie 650 that I use as a Farm Utility Vehicle and was wondering what mods that you think that I can/should put on my 650. We don't race, hunt with it on occasion, mostly used on our small farm. Couldn't afford a tractor so I got the best of both worlds.

Over the last month and a half it is getting harder to start and runs rough, keeps cutting out, Backfires . . . no power! What's up??? I have read here about Red/black springs, Jetting, snorkels, etc …. We do a lot of stop n’ starts, short hauling, fence line checking and rebuilding, manure moving, plowing …… farm stuff. What do I really need at this point.

Any help you can send my way would be appreciated!!!

Check your air filter, make sure it's clean.

 

Thanks for your reply!

I pull out the air filter once a month and clean it. Should I get a K&N or a TwinAir filter to replace it?

 

Sounds like your choke may be sticking... Mine was doing this and found that the chokes were stuck about half way... As far as rough starting a jet kit and K&N and shes starts and idles much better..
Later

 

Thanks FishHead

Jet kit . . . . which one? (make and model) we live in PA and the Alt is +/- 1400ft so . . . .....

 

If your just doing start and stop riding, i would take it out for a good ride, open it up and give the engine a good running. Twin air filter would be a good mod.

 

I would recomend the Black spring for sure. Sounds like you need more in the way of dependability than speed, therefore I would keep it mostly stock. Alot of mods require other mods to get the benifet from them. If pulling power is what you need you could get the holeshot module, this will improve your low and mid range power and does'nt seem to require any additional mods. Tires will help alot with the chores as well, the stock tires are no good. So for a reliable powerhouse with traction this couldnt hurt, If you want to get deeper in mods Im sure the guys on this forum will be a big help.

 

So far i should keep it 90% stock!
New air filter (K&N or Twin AIR)
Holeshot module . . .. ..... new info on this Rivermud Who, where what, why???
Black springs ..... was reading about these on NYROC's page.
New tires.... i see alot of hype on tire what brand and tire treads are best for what i need?

how about Progressive springs/shocks???

AND Open it up once a month!!!!

 

DBCooper,

If it doesn't already have it done get the choke spring upgrade. As fishhead stated earlier this was a problem on '02 models. Check your airscrews and adjust to about 2.5-3 turns out from closed. I'd go with the twinair filter in your case, it filters fine particles better than the K&N and I would think you'd get a fair amount of dust. Black secondary spring is a must for your start and stop riding and keep the deflection to the low end of the 22-27mm spectrum to get the best belt life. I wouldn't bother with a primary spring. Replace the stock tires with something in the stock sizes and in a tread pattern that will suit the conditions around your farm. Since I don't think you should go with any exhaust or intake modifications then the stock jetting should suit you fine. Also, the holeshot module will probably be too abrupt for constant start and stop use. The progressive spring upgrade is probably well suited for your conditions as the stiffer suspension could be an asset around the farm. Hope this has been some help.

 

Scotia650,

Thanks for the advice! the critter is going to the Dealer on thursday for its Yearly. Should i tell him i want the choke spring upgrade or just DYI??? Should i be letting this machine run insteat of stop n' go?

Can you give me a direction on this statment of yours to read up on ". . . and keep the deflection to the low end of the 22-27mm spectrum to get the best belt life." HUH???? I'm onyly starting to learn how to do my own maintainance.

We have a small horse farm that my wife has wanted all her life and I started working on her dream Farm as a full time job! I do all the manual labor and training she rides!
