$10,000 to $15,000 for a Mod Engine is exactly why I had to get out!
I'm sure the top dogs are spending more than that now days!!!
I did the bulk of my own engine work too, labor wise.
That has been a few years back.
I just can't realistically afford that anymore.
I think Jim and Tom make some good points..............
(#1) YOU Ended Up OK! As a Parent; THAT IS My Main Concern!!!!
(#2) You might be able to find a wrecked bike that the engine will be usable for a reasonable price. Remember that you have parts from the blown engine that you can use also.
(#3) Can't expect the parents to cover "ALL" the costs..............
Find some sponsors to help defray the costs. Unfortunately, that will likely fall on your shoulders.
Don't be shy about asking friends, neighbors, other family members.
Read the threads on sponsorship. Might give you some good ideas!
IF "YOU" Truely want to race; "YOU" will be the one to find the solutions!
I'll help you with what I can. PM or Email me.
I Wish You The Best Of Luck!!!
