ya they released it early I guess.

how often do you guys replace your piston an rings in your 4 strokes?

 

[monsterSJ]

i usually do it halfway through the season just to be safe prob dont need to but it doesent hurt to tear her down every so often to inspect

 

[CarFanatic]

how long does it take to drop in a piston and rings? Just curious. I take it your leaving the stock rod and bearings alone.

 

[monsterSJ]

not too long its pretty easy and if you are just a rec rider this will obviously not need to be done this often i know guys that have 2 seasons on theres
and they are top b riders so it really depends how you ride the thing
and what not i have never had to touch the bottom end usually 1 time i had to putt a new crank in a yam 250f other than that i think for the most part there bulletproof

I"m really liking the new kawi quad. The guys at the shop said all the 450's require more maintence. They said rings and piston once a year. I was kinda shocked by that since its a 4 stroke. I am only a rec rider. Just going to be a toy to play on. They said the suzuki 400's are great rec quads, but I'm not feeling it. Great price on them though.. I dont mind maintence I enjoy workin on that stuff. Just trying to get a better idea of how solid these 450's are. I'd hate to be wrenchin more then enjoying!

i dont think youll halfto as long as you keep the valves in spec and change the oil you should be good ive never heard of anyone haveing probs with that motor other than little things but im almost poss that kawi fixed the issues they were haveing after 06

 

[CarFanatic]

man I hope so! Valves are easy to check.. I guess you just have to use different size shims to keep them in spec correct?

if i was gonna get a quad id get the suzuki 450. i rode one and it was so easy to ride, i jumped everything on the track including an 80 foot triple. those things float like u wouldnt believe.

 

[CarFanatic]

ya the suzuki's are to wide for me since I will mostly be on trails. Thats really thats all around me.

 

[CarFanatic]

what do you guys know about the raptor 700r. It from what I read seems to be a great trail quad. lower compression so maintenance isnt' has much. maybe?

 

[kx454]

they are big and heavy, good in a straight line..... the 450 motors for rec riders are pretty bullet proof if you change your oil and do regular maintenence. get a 450 you wont regret it at all.

 

[CarFanatic]

cool. I"m going to check them out tomarrow in person at some dealerships. but If I go quad which I think I am, its either the kaw, or raptor. both are fuel injected. kawi is 363lbs and raptor is 396. so ya I am worried about size and wieght I"m 5'10 155.
