Everyone has his favorite. From memory, these are in current production:

Jemco
Spec II
Higgspeed
Proflo (or something similar sold by FBG)
WTF (cone kits by Walms, on this board)
Denco (reproductions by me)

I'm sure I missed something.

I vote Denco; good torque down low and resonably high max RPM
No point getting pipes until you get the thing running right; as mentioned by others, if the baffle is clean (or removed) the bike still has a serious problem that will need to be found and repaired before aftermarket items can be succesfully used (IMO & IME; not trying to be a preacher but have been down this road and trying to save you time and $$)

Here is one guy's opinion... there are surely many that differ.

First you need to know what you have in the way of porting. The only way to know is to pull the cyl and do a port map. It can be seen that someone has been grinding. How much and where can be a factor in selecting pipes.

Porting will generally rob low end torque for added high end performance. A "fat" pipe can help restore low end performance without being detrimental to high end performance.

There is also an issue of cosmetics as the pipes mentioned have different looks.

How you ride and where is also a factor. Riding in town traffic with stop and go is better suited for one type of pipe rather than one that is normally run at hiway speeds.

So, it is largely a degree of rider preference but tempered by what, if any, porting is done to the motor.

Wirges are the least desirable and they were made with and without an internal baffle. If what you have has an internal baffle, it can clog and cutting it open is the only way to clear it. JA mentioned knocking out the plug with a broom stick or such and that can help.

It would be much easier to deal with all your issues if stock porting was present. Porting can be good or bad depending how and what was done. It can help or hinder performance but the main thing is to find out exactly what you have first or you can spend a lot of time and money for nothing.

Before you pull the cyls do a leakdown test. Otherwise, unless you plan to have the crank rebuilt it will still be a guessing game about crank seals.

Leak down test? Do I make block off plates for the intake and exhaust and put the squeeze ball to it? How much psi and for how long should it hold? Engine warm?

You really need to test vacuum and pressure. Don't use more than 6 psi, it should hold for 6 minutes. They may hold, but for how long? And yes block off the intake and exhausts.

I was just lazy when I did my H2c, had it running, took it to Brian H....... WAY BETTER.

Farming it out sometimes is the best way! I don't know any locals I trust with it at this point and I have some time ( let me re state that, I'm not in a hurry).

Not to hijack your thread but did I hear chainhsaw????

I have a few
