Just got my bike back from the shop with 351 kit installed. Bike has some "authority" to it now. I installed the pumper carb too. I also have the FMF Q4 and Powerbomb. Only issue was the fuel line from the tank to the carb. The angle is alittle awkward and tends to pinch. Only thing left is to break it in which I'll do riding to work. Can't wait to take it to Tahuya!

Thanks for all the posts on this forum, my main source of information.

//Need to send old cylinder back to Bill.
//Moto-Tune is next. I'm fortunate to live in same city as the company, I can just drop off my suspension.

 

Right On. Congrats

 

I've got my 351 kit, just need to put it on. Can't wait. Congrats on yours - power looks good.

 

put a stainless spring inside the tubing

 

wow, thats the best dyno chart i have seen for a before and after. bill should post that on his site. now maybe ill get my kit once i get tax returns.

 

a little while ago i saw on the forum that a motor cycle dealer put bills 351, tm33, and p-bomb and two bros slip on. they stated that they were getting 30 odd rwhp. any one know more on why there would be a difference

 

Different dyno's, different weather, maybe one was an engine dyno and the other a wheel dyno

 

Type of rear tire also. The more aggressive the knobby the lower the HP/torque reading on the dyno.

 

Let me know when you go it would give me a reason to go!

 

you show a gain of 5 HP and 7ftlb torque,
I thought the stock bike was like 17 HP, was your dyno pull totally stock and then 351??
