I have an lt250r that has some minor work. mosly bolt on accessories. i have done some 300 ft. races and it does good for what little is done to it but i am looking for more. i would like max. hp out of the motor. however, i have heard that the suzuki LT motors become fairly unreliable once they start producing big hp. i heard that the clutch and tranny wont hold up and perform well and most importantly they wont be reliable. now i understand that once you produce big hp you comprimise your motors reliability but i was told that if i go with a trx250r motor it will be more reliable with big hp. There is also the factor of aftermarket parts. they seem to be getting harder to find for the LT motor (especially clutch components) where parts for the trx250r seem to still be available and somewhat easy to locate. i dont plan on taking the motor over 270cc for now, i want to start small and work up. however i am thinking about an over ride tranny. if you have any experience with either of these motors then please help me out i would greatly appreciate it, i just need a little guidance as to which motor to choose. also, if i do go with the trx motor i am going to try and fit it into the lt chassis. dont know if it will work, but it will make things a little cheaper till i can afford a rigid chassis. im tryin to focus on the motor first, then move onto an aftermarket chassis. thanks for the help.
