I also put a new piston in (even though the old one was perfectly fine) so my first 4 mile loop around my favorite riding area was going to be relatively slow. The bike starts quickly and idles just fine. I take off down the trail and hit the first set of water breaks in 3rd gear,, blip the throttle good like I always do to clear the paddle on the other side of the water break and damn, it launches the bike off the top and I very nearly loop it out. I felt like a total idiot and was very glad no one saw that move. Continue on down the trail and the motor is almost unmanageable, it pulls so hard the front is in the air or the rear is spinning. I had been running the PV adjuster flush and I headed back to the trailer for some adjustments.
I turned the power valve in a turn and a half and that cured the monster hit down low but it is still a raging motor. Kelsey said it was worth a "couple" of horsepower but the butt dyno says it's more than a couple. I may go in another turn on the PV and see what happens. May fatten up the needle also, seems a tad lean.
It really transforms the motor, it even sounds different. Probably the most bang for the buck of any engine mod I've ever done.
The motor also runs a lot cooler.
Can't wait to see what you think about it.
PS I don't work for RK Tech and this is the first product I've ever bought from them.
Wow that sounds great!!!
It’s why I thought it would be worth buying. Thanks for the feedback!!!!
Now Im almost thinking Of a tiny bit of buyers remorse... that’s a big Almost!
I went riding Monday in some tech trails and thought to myself that my bike has tons of power. Do I really need more? Of course not lol but I will see. Your description sounds similar enough to what Kelsey . Actually he said “Trust me” so I did.
I like that you say the bike runs cooler. That was my first concern. It’s sounding like it’s like my old 430 Husky in the 80s. .. but with a lot less vibration..It’s sounding more like an old school big bore 2t... in some ways. This sounds fun and exciting!! Now I have a better chance of killing my self flashing back to my 20s
Shit.. makes you wonder how the race gas version would be. .. a Big Beta beast!
