viper needs more power what to do????

[live2rideyamaha]

So i just got done riding for the year and I am trying to decide what to do for next year. I am a big Yamaha fan so I am not ready to go to another brand yet. I have an 05 yamaha viper that I extended to a 162 not much don e really just geared down and tripple pipes. I am ready to spend a little money but just done know if its worth it. I have ridden and apex and a nytro and i just really like my viper, so what do i do. I keep thinking Big Bore but dont want to hassle with a bunch of problems. so this is what I want to do what are some of your opinions. let me know what you think.
any help would be great
thanks

i don't know if you can handle more power

mcx 270 nytro before you switch brands

Get it race ported, think it gives around 15hp, the max hp I've seen on a 700 viper is 163. You could get a A/M head, w higher comp. bore your carbs to 35.5mm and tune your clutch.

viper

thanks for the suggestions, my buddy was doing some searching and Hauck has a 780 big bore kit on sale right now for $1500 im thinking that may be the way to go.

IMO you can't go wrong with Hauck, I've used their stuff over the years and it comes with a lot of race proven results, bulletproof, worry free, great sound too. for 1500$ you'll be really happy, now just start shaving some pounds here and there and you'll have a beast

I ran with some guys with the Hauk 780 kit. I ended up with the Bender 835 kit. with stock carbs their pipes and CLUTCHING( not theirs). I had a lightweight viper and rode with a friend who bought an Apex from Squamish dealer(knows what he is doing) He was running 10 lbs boost, and I could hole shot him up to 80 mph. That kit rips and on a dyno is putting 180 hp, then I added a 40 shot of go juice Just make sure you seal the pipes and get lots of fresh air to the engine...whole new world.

gotta ask mcx nytro, how's the cooling problems w a 835kit? since they want to get hot stock.

I say leave the motor stock and do lightweight parts first. A stock motor will ALWAYS be more reliable than a mod. Maybe get the head with interchangable domes for high/low elevation. To bad the Viper weighs so much more than a MM or SX chasis..

room for improvements

sky is the limit on what to spend. porting definitely helps. I heard you need to get an opticool gasket to keep your motor from getting to hot. vipers have a heat distrbutionn problem. I wouldlook at clutching, gearing, and dropping weight. you get those right and its a whole new world. lightweight trailing arms, lighter skid. no action skid is a boat anchor. It depends on what you want the sled to do. Highmarking, boondocking, trees. but any or all will help. my 2 cents

viper skid

I found an 05 162 skid from an M7 cat. are these good skids to use. I have seen in other posts that a 153 AC skid is the way to go for a 162 yami
any input on this.

I just read up on a guy that did that skid on his Viper and said he loves it and it makes the sled a whole new machine and feels much much lighter, transfer good. Cat makes some good products. If you can get a skid with the floats I think you will be golden. But i would put the sled on a diet first rip everything off you dont think you need, get some light weight trailing arms,hood,raidus rods, handle bars. I know years ago when I bought the 08 Nytro RTX I drove it one season for warrenty then that summer ripped off everything i can and I managed to drop like 25lbs off the sled and found most of the wieght in the rear skid.

I ran a Cat skid in mine as well. Along with some other light weight stuff, such as trailing arms, etc and if I remember correctly it saved about 25-30 pounds. Most of it was in the rear skid as mentioned above, the stock pro-action skid weights 74 pounds .
The sled had triple pipes and some mild port work done, which I believe was good for around 160 hp. It ran pretty strong
Main thing is to get fresh air to the intake, I drilled several holes in the cowl behind the windshield and sealed it off from under the hood. This kept the hot air/steam from entering the motor. You do have to jet up when doing this mod though.
