trx 90 motor swap

[tomcat7810]

hi, I am new to the trx 90 world however I have one laying around. I was wondering what kind of motor swaps in very easily with more power? my motor may be toast so i am considering something new. I seen some do a 85cc 2 stroke swap that looks sick is that swap hard?

i have a stock 06 trx90 motor with only about 10 hours on ill sell everything engine wiring harness carb for $450 +shipping. the crf150r swap was a nightmare so im sure the 85cc would be alot easier since the head and all is so much smaller but the head pipe might give you trouble. but then your also going to have to upgrade your suspension cause the stock suspension wont hold up. so your easily looking at a 5,000 + swap

ok I may consider that i just need to get some money together
