Hello started around 1995 with an fl250 odyssey then got an 250r got a trx250r when I was 15 in 98. i wanted a banshee but they told my mom it was too much and the dealership actually wouldn't sell her it but they would sell me the trailblazer but I was done with CVT transmissions I wanted efficiency. So the performance shop in town sold us a customer's rebuilt 87 trx250r everything stock but some porting and high compression aviation gas . So as u know every modification I did was a crazy jump in performance and I was hooked throughout the years I did in order iirc fmf rev pipe, fmf ram valve, bored and modded stock carb to 36.5 I think, then upgraded to 38 air strikeer lrd high rev cdi, nology coil thing was a high revving beast. Then I think I had a bad water pump and they discovered a crack in the cylinder so rebuilt with different cylinder and it never ran the same. Changed it up a bunch of times and never got good results. I completely rebuilt customized everything then sold it and just bought it back I'm going to try replacing flywheel harness and cdi and see where that gets me.
