2001SRX=Fast

Okay guys I have a 2001 SRX and I need a little bit more kick out of her. I have a set a cylinders sitting in the garage. Should i get them done to a 780 or a 835? I hear and have seen the 780's go down VERY easy in the mid range. Are 835's the same? Or should i save my money and port the cylinders I have on now? I have the hauck stingers and i will hopefully have a Ripsaw comming with in the next few weeks. I am also open to suggestions.

If you go the 835 route you will find youll need alot more money to get the sled to run properly, your gonna need a set of $1000 pipes right off the bat, bore your carbs, and be stuck with cast iron lined cylinders, these dont transfer the heat out of the piston as fast as the nikasil cylinders do. If you go 780 route, your gonna need cylinders bored and replated, then your gonna have special pistons needed and if you were to break something, gonna have to spend alot more $ on a replacement piston, and no one but Hauck,cpr,etc is gonna have them in stock. The other thing is the rings are thinner on the wiseco pistons and will need to be changed sooner then stock ones will to retain good compression and performance. Remember 1 thing, piston /ring performance is critical in a 2 stroke for max performance. The 780 will run very well, in my opinion, it still needs refinements to be "great" instead of just "good", alot of places just simply bore the cylinder, whack the head/exh valve and the 780 really wont make any more power, it needs some porting and other slight tweaks to shine. Your last option is to port your existing cylinders, you can obtain almost the same power output as you do from a 780, it takes porting, piston,head work to do this, but you have a dead reliable engine that works great and replacement parts are in stock. 835, will make alot of power,never dyno'd a 835 myself, but understand a good running one is 185hp, 780 kits are in the 160hp range, a properly done ported and slight engine tweaked 700 is 155-160hp, so pick your poision!

yep they are around 2 grand. I bought a trashed top end for $50, sent to Jeff and he did a really nice job(he doesnt just bore and cut the valves). Great power and no problems. I used his jetting specs, plugs , wash and egts are the same as a stocker. I ride from 1500' to 10000' give the veriflow 3 clicks and Im good to go.
