These are all the factors i am looking at and was really thinking about getting one of them, first its vitos 404cc, trinity 420cc reg rod,lrd 380cc,ct 370cc log rod, which of these are the best for a guy who wants to hang with the 500cc dirt bike boys.

 

get a dirt bike, sorry but thats the way it is

 

come on lets get some real answers

 

I don't really know since I have none of these (yet!). The vito 404 looked very well priced at first...but you have to add 320$ for the sleeving job, which makes it more expensive than the Trinity (420RR is 700$, and vito is 470+320)(I don't know if you have to add anything for labor and such).
That's the only thing I know about this...

 

I have been wondering the same thing. Who gives you the most for your money. I don't mean by that who is the cheapest either. what i mean is for spending the money which engine is going to be the most reliable and have the best quality components used, which company has the best customer service, and finally what the total cost would be to have that done. I have heard good things about lrd although i would like to have at least some idea about how much their 380 kit costs. I to would appreciate anyone who has had any of these companies do work for them respond a give us some feedback, How long did it take, How happy are you with the results, How helpful was their customer service, finally how much total did it end up costing by the time you finally got done.

 

I think for the vitos you can add antoher $300 on there for labor. you can read all about vitos kit at www.mobiledyno.com. I would probably go with Vito since he is in Michigan and I am in Michigan, I can just drive my shee down there and pick the whole thing up when he's done. Have you looked at FMF's PowerValve 400?

 

The company I'm looking at is PSI Performance. They are famous for the dependable snowmobile motors (300+ hp) and are now getting into high-tech ATV motors. I know they offer motors for the 250Rs (I'm looking at the 425cc Genisis Power-Valve 72hp motor for my 250R), but I'm not sure about other quads at this time. Give them a call and see what their plans are. Their customer service has been great. The web site is...
