So Ive always heard the best things about boysen reeds. Certainly not so with moto tasarni... So towards the end of last season I bought some carbon reeds from them and got perhaps 20 hours on them. When Rebuilding my motor this week I notice every single petal on them is peeled back and not...

So in the process of rebuilding my motor I lost my stainless head bolts. What size and thread are these? Thanks

So I just finished working on my ports, and THEN i realize while I was smoothing out the edges I made a hump in the floor of both exhaust ports. So basically I made the two bottom corners lower than the middle. Will this be prone to ring grabbing and do I need to concave the floor...

So my question is not so much the routing of cooling as much as it is with how I should deal with my flow control valve. Ive basically created a jetworks valve that pops off between 2-4 psi approx. As you can see in my diagram I have 2 bypasses. And mostly my question is should I...

38's or BlackJacks.... 38's, they are neither Overpowered, nor OverRated. Talk amongst yourselves

I never thought this day would come. Today is the happiest day of my life.

So I finally bought went to town to do everything I could while waiting for Nikad to (not) ship my exhaust, so heres what I did. Bought some tubbies off SurfJetLouie after I rode his 550 one's and loved them. So I glassed them on with some 404, and then ran 8" strips of kevlar down the sides...

Can someone that knows him ask how/when he shipped my B pipe, or if he even has yet? Its been 3 weeks or so.. Kthnx.<3

So this is basically what my SquareNose is up to now. Ive just added the flywheel, boysens, and removed the riva red pipe. Ski is still not together and I have no idea how it rides, but as of last ride it deffinately didnt hit of bottom like Id want... I have the engine apart and I'm...

Searched around a bit and I know that you need to bore the B pipe to 47-49mm, however I cant find specifics... I measured the manifold, and the opening is at 46mm, but just below that is a taper down to 44mm. I figured it is obvious this needs to be bored out to 47 or greater. But...

Almost bought a set of 46 buckshots, was advised against it and decided not to buy at the last minute. Very fuel hungry and they need a real strong vacuum signal. So perhaps someone can tell me about ProTec 46's. Ive heard that unlike OEM 44's, OEM 46's perform pretty damn good without...

I searched... found threads on each but not a comparison. Boysen or Vforce 2's? Whats better? From what I understand Im more apt to get boysen than the vforce 2's.

Dont do business with him. He may lure you in with cheap prices, but thats the end of the good deals. First off he has no idea what hes doing, and secondly, hes not willing to fix his own damn errors. He screwed me over 3 times in one day. Nothing very bad but just enough to...

i have a 92 square nose with a 61`x/62t, dual 38s, vortex f/a's, riva red pipe, porting (dont know what extent, already done when purchased) and a triton engineering head touching down at 190 psi. I got my main jet tuned a while back, but ended up never working with the low speed jet...

or whatnot. 62t/61x 701. Dual 38's, riva red pipe, porting(dunno what extent) My low jet is 67.5 and my high jet is 125. The high is awesome but the low seems like crap. Any recommendations?

are the 650 and 701 chambers different? From what I understand all i gotta do is bore the manifold outlet up to 46mm and match the inlets to the larger exhaust ports. Or is the thing different enough to just skip a 650 pipe and look for a 701 pipe?

So I was rudely awoken at 2:30 this afternoon by a text message that said I am a hourly winner that I needed to go to the alpha trade wamiltons booth to pick u p my prize. I wasnt aware when I entered the alpha trade sweepstakes I had to be there. Anybody wanna pick up my prize or tell me...

What will hit more? Ive read mixed reviews... but most people say the blaster pipe absolutely rips. Id like a deffinate whats what. 62t/61x w/ dual 38s triton eng head 200 psi. motor has apparently been bored once over and ported but I dont actually know to what extent. Right now...

Who sells a replacement needle with either a T-bar end or a big fat nob on it? I cant tune my duals worth crap. Could this be a dealer part to go pick up for this weekend?

Lets keep it short and sweet. Im about to put some footholds in my superjet. I glassed my own molded to my feet for my 550, but dont really have the time to go through that again so Im just gonna buy some. Heres my things. 1) I dont like a huge out cropping... I like the overhang to...
